ACU16-C/NHB32-C
Owner’s Manual Addendum
Please make the following changes and additions to the ACU16-C/NHB32-C owner’s manual. Some of
these are due to the ACU16-C/NHB32-C system software upgrade, while others are corrections and
supplementary explanations.
Changes due to the software upgrade
Support for CobraNet “Low Latency” (system software v1.10)
In conjunction with the upgrade to system software V1.10, the latency setting that had been fixed at 5.33 ms can now be
selected from three choices (5.33 ms/2.67 ms/1.33 ms). This allows even lower-latency distribution of audio signals. In
addition, you can now make connections at the desired latency to digital mixers such as the PM5D or digital mixing engines
such as the DME64N/24N via the Yamaha “MY16-C” card.
Changing the latency can be done in conjunction with NetworkAmp Manager V1.1.0E. For the procedure, refer to the
NetworkAmp Manager owner’s manual (PDF format).
The latency and audio bit depth settings will determine the limits on the number of channels that can be distributed in one
bundle, and the number of bundles that can be distributed.
NHB32-C
•ACU16-C
If two or more different latencies exist in a CobraNet network, it may become impossible for the various devices to
communicate correctly. You must make sure that all CobraNet devices in a single network have the same latency setting.
Additions and corrections
Cable Length & Switching Hubs
The maximum length of a cable used in a 100Base-T Ethernet network is 100 m (a maximum of 2 km for a multimode optical
fiber cable), but depending on the type of cable used and on the performance of the switching hub, there are cases in which
this length cannot be guaranteed. Three or four switching hubs can be connected, but this also will depend on the
performance of the switching hub.
“System Requirements (NetworkAmp Manager)” (page 10)
The following items have been added to the operating requirements for NetworkAmp Manager.
•If your computer has HyperThreading Technology, you must disable it when connecting via USB.
•This software cannot be used on a computer that has multiple CPUs (e.g., Intel’s Xeon processor or AMDs Opteron
processor).
•This software cannot be used on a computer that has a dual core CPU (e.g., Intel’s Pentium-D processor or AMDs
Athlon64 x2 processor).
•This software cannot be used on a computer running Windows XP x64 Edition.

“Installing Acrobat Reader” (page 12)
Incorrect—To view the Network Amp Manager Owner’s Manual, you’ll need to install the Adobe Acrobat Reader
software, which is included on the CD-ROM. If you already have this software installed, skip this section.
Correct—To view the NetworkAmp Manager Owner’s Manual (PDF format), Adobe Reader software (free of charge)
must be installed. If you don’t have Adobe Reader, please download it from the Adobe Corporations website.

“PRIMARY & SECONDARY CobraNet ports” (page 22)
Incorrect—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the
ACU16-C uses the PRIMARY port. However, if communication via that port fails, it will automatically switch to the
SECONDARY port and operation will continue uninterrupted.
Correct—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16-
C uses the PRIMARY port. However, if system problems such as port malfunction or broken cable occur in the PRIMARY
port, it will automatically switch to the SECONDARY port. The audio signal will be momentarily interrupted, but the
duration of the interruption will depend on the performance and settings of the hub, and on the structure of the system.
“Introduction” (page 25)
Incorrect—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging between 512
CobraNet audio channels and 512 AES/EBU format inputs and outputs.
Correct—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging a maximum (total
inputs and outputs) of 256 channels of CobraNet audio and AES/EBU audio.
“CobraNet Primary & Secondary” (page 35)
Incorrect—In the first example, if a primary connection fails, the system automatically switches to secondary and
operation continues uninterrupted. However, if the switching hub fails, the entire system stops working. In the second
example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation
continues on secondary via switching hub B.
Correct—In the first example, if a primary connection fails, the system automatically switches to secondary. However if
the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for
primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B.
Be aware that with either connection, the time required in order to switch between primary and secondary will depend on
the performance and settings of the hub.
“CobraNet Primary & Secondary, Ex. 2” (page 35)
In consideration of a case in which the primary connection fails, connect switching hub A and switching hub B.

Notes on rack-mounting the unit
If you install the ACU16-C/NHB32-C along with another
ACU16-C/NHB32-C or other device in a rack that is not well
ventilated, the temperature inside the rack may rise due to the
heat generated from the devices and the devices may be unable
to perform properly. When you rack-mount the unit, be sure
to keep a gap of 1U (4.5cm) above and below the unit for better
ventilation. Also, install the ventilation panels in these gaps or
remove the partition panels.
If the temperature inside the rack is expected to be 40°C or
higher (in this case, the room temperature is generally about
30°C or higher), install the fan kit on the top shelf of the rack,
and install the ventilation panels between devices or remove
the partition panels. The fan kit must generate a maximum
wind of 1.6m
3
/min or higher and a maximum static pressure
of 5mmH
2
O or higher.
Anmerkungen zum Rackeinbau des Geräts
Wenn Sie den ACU16-C/NHB32-C gemeinsam mit einem
anderen ACU16-C/NHB32-C oder einem Gerät mit
mangelhafter Lüftung in ein Rack einbauen, könnte die
Te mperatur im Innern des Racks rapide ansteigen und Ausfälle
der vorhandenen Geräte verursachen. Lassen Sie über und unter
Geräten in einem Rack jeweils 1HE (4,5cm) frei, um eine
ausreichende Luftzirkulation zu gewährleisten. In diesen
Öffnungen müssen Lüftungsblenden angebracht werden.
Außerdem sind eventuell vorhandene Trennplatten zu entfernen.
Wenn die Temperatur im Innern des Racks die 40°C-Marke zu
übersteigen droht (was der Fall ist, wenn die Raumtemperatur
mindestens 30°C beträgt), müssen Sie ganz oben im Rack eine
Lüftereinheit und zwischen den Geräten Lüftungsblenden
einbauen. Trennplatten zwischen diesen Partien müssen
entfernt werden. Die Lüftereinheit muss einen Luftstrom von
mindestens 1,6m
3
/min und einen statischen Druck von
5mmH
2
O oder mehr erzeugen.
Remarques concernant l’installation de l’unité dans un rack
Si vous installez l’ACU16-C/NHB32-C dans le même rack
qu’un deuxième ACU16-C/NHB32-C ou tout autre dispositif
avec une ventilation autonome plutôt limitée, la température au
sein du rack pourrait très vite monter à des valeurs qui
empêchent les unités de fonctionner correctement. De ce fait,
pour le montage en rack, il convient de laisser un espace d’1U
(4,5cm) au-dessus et en dessous de tels dispositifs pour assurer
une bonne circulation d’air frais. De plus, il faut couvrir les
ouvertures ainsi laissées avec des panneaux de ventilation.
Retirez toute cloison éventuellement présente entre deux unités.
Si la température au sein du rack risque de monter au-delà de
40°C (auquel cas la température ambiante s’élève à 30°C ou
plus), installez un kit de ventilation en haut du rack et des
panneaux de ventilation entre les unités. Retirez en outre les
cloisons qui les séparent. Le kit de ventilation doit générer un
flux d’air supérieur à 1,6m
3
/min et une pression statique de
5mmH
2
O ou plus.
Notas acerca de la instalación en rack de la unidad
Si instala el ACU16-C/NHB32-C junto con otro ACU16-C/
NHB32-C u otro dispositivo en un armario rack que no esté
correctamente ventilado, la temperatura en el interior del
armario puede elevarse debido al calor generado por los
propios dispositivos y afectar al correcto funcionamiento de
los mismos. Cuando instale la unidad en rack, asegúrese de
dejar una separación de 1U (4.5cm) por encima y por debajo
de la unidad con el fin de conseguir una correcta ventilación.
Además, instale los paneles de ventilación en estas
separaciones o elimine los paneles de partición.
Si se calcula que la temperatura en el interior del rack sea de
40°C o más (en este caso, cuando la temperatura de la
habitación es de 30°C o superior), instale el kit de ventilación
en la parte superior del armario rack e instale los paneles de
ventilación entre los dispositivos o elimine los paneles de
división. El kit de ventilación debe generar un caudal mínimo
de 1.6m
3
/min o superior con una presión estática mínima de 5
mm H
2
O o superior.

Important Note for PC-N Series Power
Amplifier Users
When you are using the ACU16-C connected to a PC9500N or
PC4800N power amplifier, the NetworkAmp Manager's meter
may not display the correct value, depending on your power
amplifier. Please check your power amplifier for the following
items to find out whether the problem has been fixed on your
amplifier:
Locate the product serial number label on the packing container
or on the rear panel of the power amplifier.
•If the first two alphabetical letters in the serial number are IL,
IM, IN, IO, IP, IX, IY, IZ, or JH, the problem may not have
been fixed on the amplifier. Otherwise, you can assume that
the problem has been fixed on your amplifier.
On units that have a serial number that begins with any of the
letter combinations described above, if there is a green round
sticker adjacent to the serial number label, the problem has
been fixed on the unit.
If the problem has not been fixed on your power amplifier,
contact your Yamaha dealer.
Wichtiger Hinweis für den Einsatz von
Endstufen der PC-N-Serie
Wenn Sie den ACU16-C an eine Endstufe des Typs PC9500N
oder PC4800N anschließen, zeigen die Meter von NetworkAmp
Manager eventuell nicht den richtigen Wert an. Wenn das bei
Ihnen der Fall ist, können Sie folgendermaßen ermitteln, ob das
Problem der Endstufe behoben werden muss:
Bringen Sie die Seriennummer Ihrer Endstufe in Erfahrung.
Diese finden Sie auf dem Lieferkarton und dem rückseitigen
Typenschild.
•Wenn die ersten beiden Buchstaben der Seriennummer „IL,
„IM”, „IN”, „IO”, „IP”, „IX”, „IY”, „IZ” oder „JH” lauten,
bedarf die Endstufe eventuell noch einer Aktualisierung.
Andernfalls können Sie davon ausgehen, dass das Problem
bereits behoben wurde.
•Auf Geräten, deren Seriennummer mit den oben erwähnten
Buchstaben beginnt und bei denen das Problem bereits
behoben wurde, befindet sich neben dem Typenschild ein
runder grüner Aufkleber.
Fehlt dieser Aufkleber auf Ihrer Endstufe, so wenden Sie sich
bitte an Ihren Yamaha-Händler.
Remarque importante à l’attention
des utilisateurs d’un amplificateur de
puissance de la série PC-N
Quand l’ACU16-C est branché à un amplificateur de puissance
PC9500N ou PC4800N, il se peut (selon l’ampli de puissance)
que l’affichage de niveau de NetworkAmp Manager n’indique
pas la valeur correcte. Contrôlez alors le numéro de série de
votre amplificateur comme suit pour vérifier si ce problème doit
être corrigé ou non:
Vérifiez le numéro de série de l’amplificateur sur l’emballage ou
le panneau arrière de l’appareil.
•Si les deux premières lettres du numéro de série
correspondent à “IL, “IM”, “IN”, “IO”, “IP”, “IX”, “IY”, “IZ” ou
“JH”, le problème n’a peut-être pas été corrigé sur
l’amplificateur. Si les lettres initiales du numéro de série
diffèrent des caractères ci-dessus, vous pouvez partir du
principe que le problème a été corrigé sur votre
amplificateur.
•Certains amplificateurs dont le numéro de série commence
par une paire de lettres mentionnée ci-dessus pourraient
comporter une vignette ronde et verte collée à côté de
l’étiquette du numéro de série. La présence de cette vignette
signifie que le problème a été corrigé sur l’appareil en
question.
Si le problème n’a pas été corrigé sur votre amplificateur de
puissance, contactez votre revendeur Yamaha.
Nota importante para los usuarios de
los amplificadores de la serie PC-N
Si utiliza el ACU16-C conectado a un amplificador PC9500N o
PC4800N, el indicador NetworkAmp del Manager puede que no
visualice el valor correcto, dependiendo de su amplificador.
Compruebe los siguientes elementos en su amplificador para
saber si el problema se ha solucionado:
Localice la etiqueta del número de serie del producto en el
embalaje o en el panel posterior del amplificador.
•Si las dos primeras letras del número de serie son “IL, “IM”,
“IN”, “IO”, “IP”, “IX”, “IY”, “IZ” o “JH”, es posible que el
problema no se haya solucionado en el amplificador. De lo
contrario, puede asumir que el problema se ha solucionado
en el amplificador.
En las unidades con números de serie que empiecen por
cualquier serie de letras mencionada, si observa un punto
verde al lado de la etiqueta del número de serie, el problema
se ha solucionado en la unidad.

Cautions
Installation
•Keep this unit away from the following locations:
—Locations exposed to oil splashes or steam, such as near cooking stoves, humidifiers, etc.
—Unstable surfaces, such as a wobbly table or slope.
—Locations exposed to excessive heat, such as inside a car with all the windows closed, or
places that receive direct sunlight.
—Locations subject to excessive humidity or dust accumulation.
•Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A
damaged power cord is a potential fire and electrical shock hazard.
•Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard.
•This unit has ventilation holes to prevent the internal temperature from rising too high. Do
not block them. Blocked ventilation holes are a fire hazard. In particular, do not operate the
unit while it’s on its side, is upside down, or while it’s covered with a cloth or dust sheet.
•When installing the unit in a rack, you must use the rack-mounting screw holes at the rear
in addition to those on the front panel.
•When rack-mounting or stacking several units, always leave at least 1U (i.e., about 4.5 cm)
of free space above and below the unit for normal ventilation. If the airflow is restricted, the
unit may overheat, which could cause a fire.
•To relocate the unit, turn the power switch off, remove the power plug from the AC outlet,
and remove all connecting cables. Damaged cables may cause fire or electrical shock.
•This unit is equipped with a dedicated ground connection to prevent electrical shock.
Before connecting the power plug to an AC outlet, be sure to ground the unit. If the power
cord has a three-pin plug, it will provide sufficient grounding so long as the AC outlet is
grounded correctly.
Operation
•If you know you will not use this unit for a long period of time, such as when going on vaca-
tion, remove the power plug from the AC outlet. Leaving it connected is a potential fire haz-
ard.

ACU16-C & NHB32-C Owner’s Manual
2 ACU16-C Amp Control Unit
Introduction
The Yamaha ACU16-C Amp Control Unit is a CobraNet interface offering 24-bit D/A con-
version of up to 16 CobraNet audio channels, which are output via Euro-block connectors
for connection to up to eight 2-channel power amplifiers. Up to 16 ACU16-Cs can be used
on a single CobraNet network, providing D/A conversion of up to 256 CobraNet audio
channels. Primary and secondary CobraNet ports are provided for integration in systems
with built-in redundancy.
In addition, the ACU16-C works as an interface for Yamahas NetworkAmp Manager soft-
ware, which runs on standard Windows PCs and offers control and monitoring of up to 512
Yamaha PCxxxxN series power amplifiers (32 amps per ACU16-C), up to eight NHB32-Cs,
and up to 16 ACU16-Cs. A PC can be connected directly to the ACU16-C by using either
USB or RS-232C. Multiple units can be managed from a single PC connected to any
ACU16-C or NHB32-C on the CobraNet network.
As of this writing, the Yamaha PC9500N and PC4800N power amplifiers can be networked
with the ACU16-C. Please check the Yamaha Professional Audio Web site at the following
URL for news and information on networkable power amplifiers to be released in the
future, and for information on other Yamaha professional audio products:

Front Panel
A USB port
This USB port is used to connect the ACU16-C to a USB port on a PC running Net-
workAmp Manager. The rear panel TO COMPUTER port offers an alternative method of
connection. The PC port to be used for communication with the ACU16-C is set in Net-
workAmp Manager.
B UNIT ID switch
This switch is used to set the unit ID of the ACU16-C. Each ACU16-C on the network must
be assigned an exclusive ID from 0 to 15. The following table shows how the switch mark-
ings correspond to unit IDs 0 through 15. The switch can be set by using either a small
flat-bladed screwdriver or a Phillips screwdriver.
C NETWORK STATUS indicators
LINK: This indicator lights when the ACU16-C has a valid connection to a CobraNet net-
work. If a link cannot be established, the CONDUCT and ERROR indicators light instead.
CONDUCT: This indicator lights when the ACU16-C is the CobraNet Conductor (i.e.,
wordclock master and arbitrator for the entire network).
ERROR: This indicator lights when a CobraNet link cannot be established, and flashes
when a CobraNet interface error occurs.
D POWER ON/OFF switch
This push switch is used to turn on the ACU16-C. To prevent loud clicks and thumps in
your speakers, turn on your audio equipment in the following order (reverse this order
when turning off)—sound sources, A/D converters, mixers, network equipment,
NHB32-C/ACU16-C, D/A converters, power amplifiers.
Unit ID 0123456789101112131415
Switch Setting
0123456789ABCDEF
Note: The ACU16-C must be turned off before setting the unit ID. Make sure that each
ACU16-C is assigned an exclusive ID. Assigning the same unit ID to two or more ACU16-Cs
will produce unpredictable results.
Note: Use a screwdriver that’s appropriate for the size of the slot in the switch. Using a screw-
driver with too big a handle, or a screwdriver with too small a tip, may damage the switch.
Note: If a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simulta-
neously. This type of error can be caused by an incorrect device setting or a faulty ACU16-C.
See “System Errors” on page 37 for more information.

Rear Panel
A Grounding screw
For electrical safety reasons, its important that the ACU16-C is grounded properly. The
supplied power cord has a three-pin plug, and if the ground terminal of the AC outlet is
grounded, then the unit will be grounded sufficiently through the power cord. If the AC
outlet does not provide a suitable ground, this screw must be connected to a good ground
point. Grounding is also an effective way to eliminate hum, interference, and other noise.
B AC IN connector
This connector is used to connect the ACU16-C to an AC outlet via the supplied power
cord. Connect the socket-end of the supplied power cord to the AC IN. Connect the
plug-end to a suitable AC wall outlet, one that conforms to the power supply requirements
stated on the ACU16-C’s rear panel. Use the supplied retaining clamp to secure the power
cord, preventing inadvertent disconnection.
C RS-485 port
This RJ-45 port is used to connect the ACU16-C to a network of up to 32 Yamaha PCxxxxN
series power amplifiers for control and monitoring. Networkable Yamaha power amplifiers
are connected together in a daisy-chain fashion using standard CAT3 or CAT5 Ethernet
cables, maximum length end-to-end, 1 kilometer. UTP (Unshielded Twisted Pair) or STP
(Shielded Twisted Pair) cable can be used.
D PRIMARY & SECONDARY CobraNet ports
These RJ-45 ports are used to connect the ACU16-C to the primary and secondary Cobra-
Net networks. Primary and secondary can be used to build redundancy into systems. Under
normal conditions, the ACU16-C uses the PRIMARY port. However, if communication via
that port fails, it will automatically switch to the SECONDARY port and operation will con-
tinue uninterrupted. Straight 100Base-TX CAT5 Ethernet cables should be used to connect
the ACU16-C to a CobraNet network. Use STP (Shielded Twisted Pair) cables to protect
against electromagnetic interference. If necessary, two CobraNet devices can be connected
together using a crossover 100Base-TX Ethernet cable. Straight and crossover cables are not

3 NHB32-C Network Hub & Bridge
Introduction
The Yamaha NHB32-C Network Hub & Bridge is a CobraNet bridge offering flexible patch-
ing of up to 64 CobraNet audio channels (32 in/32 out) to 64 AES/EBU format inputs and
outputs (32 in/32 out). Up to 99 patch setups can be created, stored, and recalled in Net-
workAmp Manager. Patches can be recalled directly from the NHB32-C’s front panel while
NetworkAmp Manager is offline. Up to eight NHB32-Cs can be used on a single CobraNet
network, providing bridging between 256 CobraNet audio channels and 256 AES/EBU for-
mat inputs and outputs when using unicast distribution. Primary and secondary CobraNet
ports are provided for integration in systems with built-in redundancy.
In addition, the NHB32-C works as an interface for Yamahas NetworkAmp Manager soft-
ware, which runs on standard Windows PCs and offers control and monitoring of up to 512
Yamaha PCxxxxN series power amplifiers, up to eight NHB32-Cs, and up to 16 ACU16-Cs.
A PC can be connected directly to the NHB32-C by using either USB or RS-232C. Multiple
units can be managed from a single PC connected to any ACU16-C or NHB32-C on the
CobraNet network.
By utilizing CobraNets Serial Bridge feature, MIDI data (Program Change and Control
Change), or AD824 data (head amp control) can be transmitted between any two
NHB32-Cs up to 100 meters when using 100Base-TX cabling, and up to 2 kilometers when
using fiber. Note that the Serial Bridge cannot carry MIDI, AD824, and Amp Control data
simultaneously. Only one can be selected in NetworkAmp Manager. The wordclock source
for the NHB32-C can be a pair of AES/EBU inputs, the BNC WORD CLOCK IN, or the
CobraNet network.

workAmp Manager. The rear panel TO COMPUTER port offers an alternative method of
connection. The PC port to be used for communication with the NHB32-C is set in Net-
workAmp Manager.
B UNIT ID switch
This switch is used to set the unit ID of the NHB32-C. Each NHB32-C on the network must
be assigned an exclusive ID from 0 to 7. The following table shows how the switch markings
correspond to unit IDs 0 through 7. The switch can be set by using either a small flat-bladed
screwdriver or a Phillips screwdriver.
C LOCK indicator
This indicator lights up when the NHB32-C is locked to the selected wordclock source. It
flashes when the NHB32-C is unlocked.
D NETWORK STATUS indicators
These indicators show the status of the CobraNet network.
LINK: This indicator lights when the NHB32-C has a valid connection to the CobraNet
network. If a link cannot be established, the CONDUCT and ERROR indicators light
instead.
CONDUCT: This indicator lights when the NHB32-C is the CobraNet Conductor (i.e.,
wordclock master and arbitrator for the entire network).
ERROR: This indicator lights when a CobraNet link cannot be established, and flashes
when a CobraNet interface error occurs.
E Wordclock source indicators
These indicators show the currently selected wordclock source.
AES/EBU: Wo rdclock sourced from a pair of AES/EBU inputs.

Note: The NHB32-C must be turned off before setting the unit ID. Make sure that each
NHB32-C is assigned an exclusive ID. Assigning the same unit ID to two or more NHB32-Cs
will produce unpredictable results.
Note: Use a screwdriver that’s appropriate for the size of the slot in the switch. Using a screw-
driver with too big a handle, or a screwdriver with too small a tip, may damage the switch.
Note: If a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simulta-
neously. This type of error can be caused by an incorrect device setting or a faulty NHB32-C.

F Wordclock source button
This button is used to set the wordclock source, which can be a pair of AES/EBU inputs, the
CobraNet network, or the NHB32-C’s BNC WORD CLOCK IN connector. To set the word-
clock source, use the button to select a source and while the corresponding wordclock indi-
cator is flashing, press the button again. The wordclock source will change and the
corresponding indicator will stop flashing and light up continuously.
G PATCH number display
This 2-digit, 7-segment LED displays the number of the currently selected patch.
H Patch edit indicator
This indicator lights up when the current patch has been edited since it was last recalled or
stored. When the patch is recalled or stored, this indicator goes off. Patches can be edited
only in NetworkAmp Manager.
I Patch selector buttons
These buttons are used to select patches 0 through 99. Use the Up button to increment the
patch number. Use the Down button to decrement the patch number.
J RECALL button
This button is used to recall the patch selected by the patch selector buttons. Patches are cre-
ated and stored in NetworkAmp Manager.
To recall a patch on the NHB32-C, use the patch selector buttons to select a patch from 0
through 99. The PATCH number flashes. When you’ve selected the patch that you want to
recall, press the [RECALL] button. The patch is recalled and the PATCH number stops
flashing.
Patch #0 is a special read-only patch containing initial AES/EBU to CobraNet channel
assignments. Each AES/EBU input and output is assigned to the correspondingly num-
bered CobraNet input and output. For example, AES/EBU input #1 is assigned to CobraNet
output #1, AES/EBU input #2 is assigned to CobraNet output #2, and so on.
K POWER ON/OFF switch
This push switch is used to turn on the NHB32-C. To prevent loud clicks and thumps in
your speakers, turn on your audio equipment in the following order (reverse this order
when turning off)—sound sources, A/D converters, mixers, network equipment,
NHB32-C/ACU16-C, D/A converters, power amplifiers.
Note: When you change the wordclock settings of your system, some devices may output noise,
so turn down your power amps beforehand, otherwise your speakers may be damaged.

Rear Panel
A Grounding screw
For electrical safety reasons, its important that the NHB32-C is grounded properly. The
supplied power cord has a three-pin plug, and if the ground terminal of the AC outlet is
grounded, then the unit will be grounded sufficiently through the power cord. If the AC
outlet does not provide a suitable ground, this screw must be connected to a good ground
point. Grounding is also an effective way to eliminate hum, interference, and other noise.
B AC IN connector
This connector is used to connect the NHB32-C to an AC outlet via the supplied power
cord. Connect the socket-end of the supplied power cord to the AC IN. Connect the
plug-end to a suitable AC wall outlet, one that conforms to the power supply requirements
stated on the NHB32-C’s rear panel. Use the supplied retaining clamp to secure the power
cord, preventing inadvertent disconnection.
C MIDI OUT/IN ports
These standard MIDI IN and OUT ports are used to connect MIDI devices for MIDI data
transmission via CobraNet’s Serial Bridge. Program Change and Control Change messages
can be transmitted over the Serial Bridge, however, it’s not suitable for time-sensitive per-
formance data such as MIDI Note On/Off.
D PRIMARY & SECONDARY CobraNet ports
These RJ-45 ports are used to connect the NHB32-C to the primary and secondary Cobra-
Net networks. Straight 100Base-TX CAT5 Ethernet cables should be used to connect the
NHB32-C to a CobraNet network. Use STP (Shielded Twisted Pair) cables to protect against
electromagnetic interference. If necessary, two CobraNet devices can be connected together
using a crossover 100Base-TX Ethernet cable. Straight and crossover cables are not inter-
changeable.
E WORD CLOCK 75 ON/OFF termination switch
This switch applies 75 termination to the WORD CLOCK IN. Normally this switch
should be set to ON when a wordclock source is connected to the WORD CLOCK IN. The
OFF setting is for use with wordclock source devices with special specifications.
F WORD CLOCK OUT BNC
This BNC connector outputs a wordclock signal.
G WORD CLOCK IN BNC
This BNC connector is for connecting an external wordclock signal. The wordclock source
is selected by using the wordclock source button on the front panel.
Wa r ning: Turn off all equipment connected to the NHB32-C before making any power con-
nections.

port to be used for communication with the NHB32-C is set in NetworkAmp Manager.
J AES/EBU 1–4 I/O connectors
These four 25-pin female D-sub connectors are used to input and output up to 64 channels
of AES/EBU format digital audio. Each connector handles eight ins and eight outs.
AES/EBU inputs and outputs are assigned to CobraNet audio channels in NetworkAmp
Manager.
Cable Length & Switching Hubs
The maximum cable length for 100Ba-se-T Ethernet networks is 100 meters (2 kilome-
ters with fiber optic cables). However, depending on the type of cable, switching hub,
ACU16-C/NHB32-C’s workload, etc., reliable operation with this length of cable cannot
be guaranteed. In addition, although about three or four switching hubs can be con-
nected to a network, the actual number will depend on the efficiency of each switching
hub.

ACU16-C Power Amp Control System
This example shows how up to 32 Yamaha PCxxxxN series power amplifiers can be con-
nected to a single ACU16-C for remote control and monitoring via NetworkAmp Manager.
PCxxxxN Series Amp ID Setting
Up to 32 PCxxxxN series power amplifiers, each with an exclusive ID from
0 to 31, can be connected to a single ACU16-C. The ID is set using the
power amplifier’s rear panel AMP ID DIP switch, which consists of six indi-
vidual switches, five for setting the ID, one for turning on and off termina-
tion (marked “T”). The five switches are individually numbered. IDs are set
using a combination of switches to achieve the required ID. For example, to
set ID #7, youd set switches 4, 2, and 1 to the ON position (i.e., 4+2+1=7). To set ID #25,
you’d set switches 16, 8, and 1 to the ON position (i.e., 16+8+1=25). To set ID #0, all
switches should be set to OFF. On the last power amplifier in the RS-485 daisy-chain, the
“Tswitch should be set to ON to enable termination.

CobraNet Primary & Secondary
These two examples show how the CobraNet PRIMARY and SECONDARY ports can be
used to build redundancy into systems. In the first example, if a primary connection fails,
the system automatically switches to secondary and operation continues uninterrupted.
However, if the switching hub fails, the entire system stops working. In the second example,
individual switching hubs are used for primary and secondary, so even if switching hub A
fails, operation continues on secondary via switching hub B.

Troubleshooting
Unit Symptom Advice
ACU16-C
NHB32-C
Cannot power up?
Make sure that the power cord is connected to a suitable AC wall outlet. Also
make sure that the other end of the power cord is connected to the unit’s AC IN
correctly. Use the supplied retaining clamp to ensure that the power cord cannot
be disconnected inadvertently. Make sure that the POWER switch is set to the ON
position. If you still cannot turn on the unit, contact your Yamaha dealer.
Cannot establish a
connection with
NetworkAmp Manager?
Make sure the unit is powered up and that NetworkAmp Manager is running
properly on your PC.
Have you installed the necessary Yamaha USB or CBX driver? See “NetworkAmp
Manager Installation” on page 10.
In NetworkAmp Manager, choose General Setup from the Option menu and
make sure that the correct MIDI driver is selected. If you are using a USB connec-
tion, this should be “YAMAHA USB.” If you are using an RS-232C serial connec-
tion, it should be “YAMAHA CBX Driver.”
If you have used NetworkAmp Manager with a USB connection, while the USB
cable is still connected, even if you select the “Yamaha CBX Driver,” a serial con-
nection will not work unless the USB cable is disconnected.
Check the USB or RS-232C serial cable connections as appropriate. If you are con-
necting to an NHB32-C, be sure to connect to the TO COMPUTER port, not the
COM port.
If you are using
a USB connection, make sure that your PC’s USB port is working
correctly. In Windows, open the System control panel and click the Device man-
ager tab. See your Windows documentation for further information.
If you are using an RS-232C serial connection, make sure that your PC’s serial
port is working correctly. In Windows, open the System control panel and click the
Device manager tab. See your Windows documentation for further information.
Make sure that all ACU16-Cs and NHB32-Cs are assigned exclusive unit IDs. It’s
okay to use the same unit IDs for ACU16-Cs and NHB32-Cs.
Connected the unit to a
CobraNet network and
the CONDUCT and
ERROR indicators light
instead of the LINK
indicator?
Make sure that all devices on the network are powered up.
Make sure that the Ethernet cables are connected to the unit properly (i.e., check
they’re not pushed in only half way).
Try swapping the Ethernet cable with a known good cable.
Try connecting the unit to another port on the hub.
Try disconnecting other devices from the network one-by-one to determine if
another device or Ethernet cable is at fault. CAT3 Ethernet cable will almost cer-
tainly cause problems, as will incorrectly wired cables, damaged cables, cables
deformed by tight cable ties, and tightly bent cables. When making cables your-
self, be sure to maintain the natural twist of the conductors as close to the connec-
tor as possible. More than 25 mm of untwisted cable can affect performance.
The LINK indicator is lit,
but digital audio cannot
be transmitted or
received?
Make sure that your CobraNet devices are set to transmit and receive the correct
bundles. Also check your audio connections, audio sources, and audio I/O to bun-
dle assignments.
The CONDUCT
indicator never lights
up?
This is normal. The CONDUCT indicator lights up only when the unit is working as
CobraNet conductor. This selection is made automatically and you don’t normally
need to do anything.
The ERROR and
CONDUCT indicators
light simultaneously?
A CobraNet link cannot be established. Make sure that the switching hubs and
other devices are properly connected and turned on.
The LINK, CONDUCT,
and ERROR indicators
flash simultaneously?
A system error has occurred. There maybe an incorrect setting on another device
or the unit maybe faulty. See “System Errors” on page 37 for more information.
The ERROR indicator
flashes?
An error has occurred with the unit’s built-in CobraNet interface. Check the cable
connections and settings of all devices on the network. If you cannot resolve the
problem and the ERROR indicator keeps flashing, the unit maybe faulty, in which
case you should contact your Yamaha dealer.
Audio sounds distorted?
Continuously distorted sound is most likely due to overloaded audio inputs and
levels being too high. Intermittent audio clicks and pops may be network related.
Check your Ethernet cables and other CobraNet devices. Also check your word-

System Errors
When a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simulta-
neously in a repeating patttern. You can determine the type of error by counting the num-
ber of flashes. Theres a two second pause between each series of flashes, as shown in the
following illustration.
ACU16-C
NetworkAmp Manager
cannot control and
monitor all power
amps?
Make sure that all power amps are powered up.
Make sure that each power amp is assigned an exclusive amp ID.
Check the RS-485 cable connection between each power amp. If a cable is not
connected properly, or a cable is faulty, power amps further down the line will not
be detected.
Speaker output sounds
out of phase?
Check your Euro-block connector wiring at the ACU16-C and power amps.
NHB32-C
The LOCK indicator
flashes continuously?
This means that the NHB32-C cannot lock to the currently selected wordclock
source. Check and correct the source, or select another.
The PATCH number

ENGLISH FRANÇAIS AMP CONTROL UNIT DEUTSCH NETWORK HUB and BRIDGE ESPAÑOL Owner’s Manual Mode d’emploi Bedienungsanleitung Manual de instrucciones NETWORK HUB AND BRIDGE LINK LOCK CONDUCT ERROR 88 M ACU16-C/NHB32-C Owner’s Manual Addendum Please make the following changes and additions to the ACU16-C/NHB32-C owner’s manual. Some of these are due to the ACU16-C/NHB32-C system software upgrade, while others are corrections and supplementary explanations. Changes due to the software upgrade ❏ Support for CobraNet “Low Latency” (system software v1.10) In conjunction with the upgrade to system software V1.10, the latency setting that had been fixed at 5.33 ms can now be selected from three choices (5.33 ms/2.67 ms/1.33 ms). This allows even lower-latency distribution of audio signals. In addition, you can now make connections at the desired latency to digital mixers such as the PM5D or digital mixing engines such as the DME64N/24N via the Yamaha “MY16-C” card. Changing the latency can be done in conjunction with NetworkAmp Manager V1.1.0E. For the procedure, refer to the NetworkAmp Manager owner’s manual (PDF format). The latency and audio bit depth settings will determine the limits on the number of channels that can be distributed in one bundle, and the number of bundles that can be distributed. • NHB32-C 20-bit 24-bit Latency Channels per bundle Maximum number of bundles (total of input and output) Channels per bundle Maximum number of bundles (total of input and output) 5.33ms 8 8 7 8 2.67ms 8 8 8 8 1.33ms 8 4 8 4 • ACU16-C Latency Maximum number of bundles (input only) 5.33ms 4 2.67ms 4 1.33ms 4 If two or more different latencies exist in a CobraNet network, it may become impossible for the various devices to communicate correctly. You must make sure that all CobraNet devices in a single network have the same latency setting. Additions and corrections ❏ Cable Length & Switching Hubs The maximum length of a cable used in a 100Base-T Ethernet network is 100 m (a maximum of 2 km for a multimode optical fiber cable), but depending on the type of cable used and on the performance of the switching hub, there are cases in which this length cannot be guaranteed. Three or four switching hubs can be connected, but this also will depend on the performance of the switching hub. ❏ “System Requirements (NetworkAmp Manager)” (page 10) The following items have been added to the operating requirements for NetworkAmp Manager. • If your computer has HyperThreading Technology, you must disable it when connecting via USB. • This software cannot be used on a computer that has multiple CPUs (e.g., Intel’s Xeon processor or AMD’s Opteron processor). • This software cannot be used on a computer that has a dual core CPU (e.g., Intel’s Pentium-D processor or AMD’s Athlon64 x2 processor). • This software cannot be used on a computer running Windows XP x64 Edition. –2– Incorrect—To view the Network Amp Manager Owner’s Manual, you’ll need to install the Adobe Acrobat Reader software, which is included on the CD-ROM. If you already have this software installed, skip this section. Correct—To view the NetworkAmp Manager Owner’s Manual (PDF format), Adobe Reader software (free of charge) must be installed. If you don’t have Adobe Reader, please download it from the Adobe Corporation’s website. http://www.adobe.com ❏ “PRIMARY & SECONDARY CobraNet ports” (page 22) Incorrect—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16-C uses the PRIMARY port. However, if communication via that port fails, it will automatically switch to the SECONDARY port and operation will continue uninterrupted. Correct—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16C uses the PRIMARY port. However, if system problems such as port malfunction or broken cable occur in the PRIMARY port, it will automatically switch to the SECONDARY port. The audio signal will be momentarily interrupted, but the duration of the interruption will depend on the performance and settings of the hub, and on the structure of the system. ❏ “Introduction” (page 25) Incorrect—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging between 512 CobraNet audio channels and 512 AES/EBU format inputs and outputs. Correct—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging a maximum (total inputs and outputs) of 256 channels of CobraNet audio and AES/EBU audio. ❏ “CobraNet Primary & Secondary” (page 35) Incorrect—In the first example, if a primary connection fails, the system automatically switches to secondary and operation continues uninterrupted. However, if the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B. Correct—In the first example, if a primary connection fails, the system automatically switches to secondary. However if the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B. Be aware that with either connection, the time required in order to switch between primary and secondary will depend on the performance and settings of the hub. ❏ “CobraNet Primary & Secondary, Ex. 2” (page 35) In consideration of a case in which the primary connection fails, connect switching hub A and switching hub B.

When you rack-mount the unit, be sure to keep a gap of 1U (4.5cm) above and below the unit for better ventilation. Also, install the ventilation panels in these gaps or remove the partition panels. Anmerkungen zum Rackeinbau des Geräts Wenn Sie den ACU16-C/NHB32-C gemeinsam mit einem anderen ACU16-C/NHB32-C oder einem Gerät mit mangelhafter Lüftung in ein Rack einbauen, könnte die Temperatur im Innern des Racks rapide ansteigen und Ausfälle der vorhandenen Geräte verursachen. Lassen Sie über und unter Geräten in einem Rack jeweils 1HE (4,5cm) frei, um eine ausreichende Luftzirkulation zu gewährleisten. In diesen Öffnungen müssen Lüftungsblenden angebracht werden. Außerdem sind eventuell vorhandene Trennplatten zu entfernen. F Si la température au sein du rack risque de monter au-delà de 40°C (auquel cas la température ambiante s’élève à 30°C ou plus), installez un kit de ventilation en haut du rack et des panneaux de ventilation entre les unités. Retirez en outre les cloisons qui les séparent. Le kit de ventilation doit générer un flux d’air supérieur à 1,6m3/min et une pression statique de 5mmH2O ou plus. Notas acerca de la instalación en rack de la unidad Si instala el ACU16-C/NHB32-C junto con otro ACU16-C/ NHB32-C u otro dispositivo en un armario rack que no esté correctamente ventilado, la temperatura en el interior del armario puede elevarse debido al calor generado por los propios dispositivos y afectar al correcto funcionamiento de los mismos. Cuando instale la unidad en rack, asegúrese de dejar una separación de 1U (4.5cm) por encima y por debajo de la unidad con el fin de conseguir una correcta ventilación. Además, instale los paneles de ventilación en estas separaciones o elimine los paneles de partición. D Wenn die Temperatur im Innern des Racks die 40°C-Marke zu übersteigen droht (was der Fall ist, wenn die Raumtemperatur mindestens 30°C beträgt), müssen Sie ganz oben im Rack eine Lüftereinheit und zwischen den Geräten Lüftungsblenden einbauen. Trennplatten zwischen diesen Partien müssen entfernt werden. Die Lüftereinheit muss einen Luftstrom von mindestens 1,6m3/min und einen statischen Druck von 5mmH2O oder mehr erzeugen. Remarques concernant l’installation de l’unité dans un rack Si vous installez l’ACU16-C/NHB32-C dans le même rack qu’un deuxième ACU16-C/NHB32-C ou tout autre dispositif avec une ventilation autonome plutôt limitée, la température au sein du rack pourrait très vite monter à des valeurs qui empêchent les unités de fonctionner correctement. De ce fait, pour le montage en rack, il convient de laisser un espace d’1U (4,5cm) au-dessus et en dessous de tels dispositifs pour assurer une bonne circulation d’air frais. De plus, il faut couvrir les ouvertures ainsi laissées avec des panneaux de ventilation. Retirez toute cloison éventuellement présente entre deux unités. E If the temperature inside the rack is expected to be 40°C or higher (in this case, the room temperature is generally about 30°C or higher), install the fan kit on the top shelf of the rack, and install the ventilation panels between devices or remove the partition panels. The fan kit must generate a maximum wind of 1.6m3/min or higher and a maximum static pressure of 5mmH2O or higher. S Si se calcula que la temperatura en el interior del rack sea de 40°C o más (en este caso, cuando la temperatura de la habitación es de 30°C o superior), instale el kit de ventilación en la parte superior del armario rack e instale los paneles de ventilación entre los dispositivos o elimine los paneles de división. El kit de ventilación debe generar un caudal mínimo de 1.6m3/min o superior con una presión estática mínima de 5 mm H2O o superior. fan kit/Lüftereinheit/ Kit de ventilation/Kit de ventilación ACU16-C/NHB32-C ventilation panel/Lüftungsblenden/ Panneau de ventilation/Panel de ventilación ACU16-C/NHB32-C ventilation panel/Lüftungsblenden/ Panneau de ventilation/Panel de ventilación M.D.G., Pro Audio & Digital Musical Instrument Division, Yamaha Corporation © 2003 Yamaha Corporation ACU NHB Pera_M_A Page 1 Wednesday, April 23, 2003 10:04 AM / Important Note for PC-N Series Power Amplifier Users When you are using the ACU16-C connected to a PC9500N or PC4800N power amplifier, the NetworkAmp Manager's meter may not display the correct value, depending on your power amplifier. Please check your power amplifier for the following items to find out whether the problem has been fixed on your amplifier: Locate the product serial number label on the packing container or on the rear panel of the power amplifier. • • If the first two alphabetical letters in the serial number are IL, IM, IN, IO, IP, IX, IY, IZ, or JH, the problem may not have been fixed on the amplifier. Otherwise, you can assume that the problem has been fixed on your amplifier. Remarque importante à l’attention des utilisateurs d’un amplificateur de puissance de la série PC-N Quand l’ACU16-C est branché à un amplificateur de puissance PC9500N ou PC4800N, il se peut (selon l’ampli de puissance) que l’affichage de niveau de NetworkAmp Manager n’indique pas la valeur correcte. Contrôlez alors le numéro de série de votre amplificateur comme suit pour vérifier si ce problème doit être corrigé ou non: Vérifiez le numéro de série de l’amplificateur sur l’emballage ou le panneau arrière de l’appareil. • Si les deux premières lettres du numéro de série correspondent à “IL”, “IM”, “IN”, “IO”, “IP”, “IX”, “IY”, “IZ” ou “JH”, le problème n’a peut-être pas été corrigé sur l’amplificateur. Si les lettres initiales du numéro de série diffèrent des caractères ci-dessus, vous pouvez partir du principe que le problème a été corrigé sur votre amplificateur. • Certains amplificateurs dont le numéro de série commence par une paire de lettres mentionnée ci-dessus pourraient comporter une vignette ronde et verte collée à côté de l’étiquette du numéro de série. La présence de cette vignette signifie que le problème a été corrigé sur l’appareil en question. On units that have a serial number that begins with any of the letter combinations described above, if there is a green round sticker adjacent to the serial number label, the problem has been fixed on the unit. If the problem has not been fixed on your power amplifier, contact your Yamaha dealer. E Wichtiger Hinweis für den Einsatz von Endstufen der PC-N-Serie Si le problème n’a pas été corrigé sur votre amplificateur de puissance, contactez votre revendeur Yamaha. F Wenn Sie den ACU16-C an eine Endstufe des Typs PC9500N oder PC4800N anschließen, zeigen die Meter von NetworkAmp Manager eventuell nicht den richtigen Wert an. Wenn das bei Ihnen der Fall ist, können Sie folgendermaßen ermitteln, ob das Problem der Endstufe behoben werden muss: Bringen Sie die Seriennummer Ihrer Endstufe in Erfahrung. Diese finden Sie auf dem Lieferkarton und dem rückseitigen Typenschild. • • Wenn die ersten beiden Buchstaben der Seriennummer „IL”, „IM”, „IN”, „IO”, „IP”, „IX”, „IY”, „IZ” oder „JH” lauten, bedarf die Endstufe eventuell noch einer Aktualisierung. Andernfalls können Sie davon ausgehen, dass das Problem bereits behoben wurde. Auf Geräten, deren Seriennummer mit den oben erwähnten Buchstaben beginnt und bei denen das Problem bereits behoben wurde, befindet sich neben dem Typenschild ein runder grüner Aufkleber. Fehlt dieser Aufkleber auf Ihrer Endstufe, so wenden Sie sich bitte an Ihren Yamaha-Händler. D Nota importante para los usuarios de los amplificadores de la serie PC-N Si utiliza el ACU16-C conectado a un amplificador PC9500N o PC4800N, el indicador NetworkAmp del Manager puede que no visualice el valor correcto, dependiendo de su amplificador. Compruebe los siguientes elementos en su amplificador para saber si el problema se ha solucionado: Localice la etiqueta del número de serie del producto en el embalaje o en el panel posterior del amplificador. • Si las dos primeras letras del número de serie son “IL”, “IM”, “IN”, “IO”, “IP”, “IX”, “IY”, “IZ” o “JH”, es posible que el problema no se haya solucionado en el amplificador. De lo contrario, puede asumir que el problema se ha solucionado en el amplificador. • En las unidades con números de serie que empiecen por cualquier serie de letras mencionada, si observa un punto verde al lado de la etiqueta del número de serie, el problema se ha solucionado en la unidad. Si el problema persiste en el amplificador, contacte con su distribuidor Yamaha.

The rear panel TO COMPUTER port offers an alternative method of connection. The PC port to be used for communication with the ACU16-C is set in NetworkAmp Manager. B UNIT ID switch This switch is used to set the unit ID of the ACU16-C. Each ACU16-C on the network must be assigned an exclusive ID from 0 to 15. The following table shows how the switch markings correspond to unit IDs 0 through 15. The switch can be set by using either a small flat-bladed screwdriver or a Phillips screwdriver. Unit ID 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Switch Setting 0 1 2 3 4 5 6 7 8 9 A B C D E F Note: The ACU16-C must be turned off before setting the unit ID. Make sure that each ACU16-C is assigned an exclusive ID. Assigning the same unit ID to two or more ACU16-Cs will produce unpredictable results. Note: Use a screwdriver that’s appropriate for the size of the slot in the switch. Using a screwdriver with too big a handle, or a screwdriver with too small a tip, may damage the switch. C NETWORK STATUS indicators LINK: This indicator lights when the ACU16-C has a valid connection to a CobraNet network. If a link cannot be established, the CONDUCT and ERROR indicators light instead. CONDUCT: This indicator lights when the ACU16-C is the CobraNet Conductor (i.e., wordclock master and arbitrator for the entire network). ERROR: This indicator lights when a CobraNet link cannot be established, and flashes when a CobraNet interface error occurs. Note: If a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simultaneously. This type of error can be caused by an incorrect device setting or a faulty ACU16-C. See “System Errors” on page 37 for more information. D POWER ON/OFF switch This push switch is used to turn on the ACU16-C. To prevent loud clicks and thumps in your speakers, turn on your audio equipment in the following order (reverse this order when turning off)—sound sources, A/D converters, mixers, network equipment, NHB32-C/ACU16-C, D/A converters, power amplifiers. ACU16-C & NHB32-C Owner’s Manual 22 ACU16-C Amp Control Unit Rear Panel 1 2 3 4 5 6 A Grounding screw For electrical safety reasons, it’s important that the ACU16-C is grounded properly. The supplied power cord has a three-pin plug, and if the ground terminal of the AC outlet is grounded, then the unit will be grounded sufficiently through the power cord. If the AC outlet does not provide a suitable ground, this screw must be connected to a good ground point. Grounding is also an effective way to eliminate hum, interference, and other noise. B AC IN connector This connector is used to connect the ACU16-C to an AC outlet via the supplied power cord. Connect the socket-end of the supplied power cord to the AC IN. Connect the plug-end to a suitable AC wall outlet, one that conforms to the power supply requirements stated on the ACU16-C’s rear panel. Use the supplied retaining clamp to secure the power cord, preventing inadvertent disconnection. Warning: Turn off all equipment connected to the ACU16-C before making any connections. C RS-485 port This RJ-45 port is used to connect the ACU16-C to a network of up to 32 Yamaha PCxxxxN series power amplifiers for control and monitoring. Networkable Yamaha power amplifiers are connected together in a daisy-chain fashion using standard CAT3 or CAT5 Ethernet cables, maximum length end-to-end, 1 kilometer. UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair) cable can be used. D PRIMARY & SECONDARY CobraNet ports These RJ-45 ports are used to connect the ACU16-C to the primary and secondary CobraNet networks. Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16-C uses the PRIMARY port. However, if communication via that port fails, it will automatically switch to the SECONDARY port and operation will continue uninterrupted. Straight 100Base-TX CAT5 Ethernet cables should be used to connect the ACU16-C to a CobraNet network. Use STP (Shielded Twisted Pair) cables to protect against electromagnetic interference. If necessary, two CobraNet devices can be connected together using a crossover 100Base-TX Ethernet cable. Straight and crossover cables are not interchangeable. E TO COMPUTER port This 9-pin male D-sub port is used to connect the ACU16-C to a COM port on a PC running NetworkAmp Manager. It’s an RS-232C serial interface, supporting cable runs of up to 15 meters. The front panel USB port offers an alternative method of connection. The PC port to be used for communication with the ACU16-C is set in NetworkAmp Manager. F Euro-block connectors These Euro-block connectors output 16 balanced analog audio signals for connection to power amplifier inputs. CobraNet audio channels are assigned to these outputs in NetworkAmp Manager. There are eight 6-way Euro-block connectors, each with hot (+), cold (–), and ground terminals for two audio channels. The supplied Euro-block plugs should be wired as shown. Tighten the screws to secure the wires. Be careful to clamp the actual conductor, not its insulation.

Up to 99 patch setups can be created, stored, and recalled in NetworkAmp Manager. Patches can be recalled directly from the NHB32-C’s front panel while NetworkAmp Manager is offline. Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging between 256 CobraNet audio channels and 256 AES/EBU format inputs and outputs when using unicast distribution. Primary and secondary CobraNet ports are provided for integration in systems with built-in redundancy. In addition, the NHB32-C works as an interface for Yamaha’s NetworkAmp Manager software, which runs on standard Windows PCs and offers control and monitoring of up to 512 Yamaha PCxxxxN series power amplifiers, up to eight NHB32-Cs, and up to 16 ACU16-Cs. A PC can be connected directly to the NHB32-C by using either USB or RS-232C. Multiple units can be managed from a single PC connected to any ACU16-C or NHB32-C on the CobraNet network. By utilizing CobraNet’s Serial Bridge feature, MIDI data (Program Change and Control Change), or AD824 data (head amp control) can be transmitted between any two NHB32-Cs up to 100 meters when using 100Base-TX cabling, and up to 2 kilometers when using fiber. Note that the Serial Bridge cannot carry MIDI, AD824, and Amp Control data simultaneously. Only one can be selected in NetworkAmp Manager. The wordclock source for the NHB32-C can be a pair of AES/EBU inputs, the BNC WORD CLOCK IN, or the CobraNet network.

Assigning the same unit ID to two or more NHB32-Cs will produce unpredictable results. Note: Use a screwdriver that’s appropriate for the size of the slot in the switch. Using a screwdriver with too big a handle, or a screwdriver with too small a tip, may damage the switch. C LOCK indicator This indicator lights up when the NHB32-C is locked to the selected wordclock source. It flashes when the NHB32-C is unlocked. D NETWORK STATUS indicators These indicators show the status of the CobraNet network. LINK: This indicator lights when the NHB32-C has a valid connection to the CobraNet network. If a link cannot be established, the CONDUCT and ERROR indicators light instead. CONDUCT: This indicator lights when the NHB32-C is the CobraNet Conductor (i.e., wordclock master and arbitrator for the entire network). ERROR: This indicator lights when a CobraNet link cannot be established, and flashes when a CobraNet interface error occurs. Note: If a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simultaneously. This type of error can be caused by an incorrect device setting or a faulty NHB32-C. See “System Errors” on page 37 for more information. E Wordclock source indicators These indicators show the currently selected wordclock source. AES/EBU: Wordclock sourced from a pair of AES/EBU inputs. NETWORK: Wordclock sourced from the CobraNet network. WORD CLOCK IN: Wordclock sourced from the NHB32-C’s BNC WORD CLOCK IN connector. ACU16-C & NHB32-C Owner’s Manual Front Panel 27 This button is used to set the wordclock source, which can be a pair of AES/EBU inputs, the CobraNet network, or the NHB32-C’s BNC WORD CLOCK IN connector. To set the wordclock source, use the button to select a source and while the corresponding wordclock indicator is flashing, press the button again. The wordclock source will change and the corresponding indicator will stop flashing and light up continuously. Note: When you change the wordclock settings of your system, some devices may output noise, so turn down your power amps beforehand, otherwise your speakers may be damaged. G PATCH number display This 2-digit, 7-segment LED displays the number of the currently selected patch. H Patch edit indicator This indicator lights up when the current patch has been edited since it was last recalled or stored. When the patch is recalled or stored, this indicator goes off. Patches can be edited only in NetworkAmp Manager. I Patch selector buttons These buttons are used to select patches 0 through 99. Use the Up button to increment the patch number. Use the Down button to decrement the patch number. J RECALL button This button is used to recall the patch selected by the patch selector buttons. Patches are created and stored in NetworkAmp Manager. To recall a patch on the NHB32-C, use the patch selector buttons to select a patch from 0 through 99. The PATCH number flashes. When you’ve selected the patch that you want to recall, press the [RECALL] button. The patch is recalled and the PATCH number stops flashing. Patch #0 is a special read-only patch containing initial AES/EBU to CobraNet channel assignments. Each AES/EBU input and output is assigned to the correspondingly numbered CobraNet input and output. For example, AES/EBU input #1 is assigned to CobraNet output #1, AES/EBU input #2 is assigned to CobraNet output #2, and so on. K POWER ON/OFF switch This push switch is used to turn on the NHB32-C. To prevent loud clicks and thumps in your speakers, turn on your audio equipment in the following order (reverse this order when turning off)—sound sources, A/D converters, mixers, network equipment, NHB32-C/ACU16-C, D/A converters, power amplifiers.

The supplied power cord has a three-pin plug, and if the ground terminal of the AC outlet is grounded, then the unit will be grounded sufficiently through the power cord. If the AC outlet does not provide a suitable ground, this screw must be connected to a good ground point. Grounding is also an effective way to eliminate hum, interference, and other noise. B AC IN connector This connector is used to connect the NHB32-C to an AC outlet via the supplied power cord. Connect the socket-end of the supplied power cord to the AC IN. Connect the plug-end to a suitable AC wall outlet, one that conforms to the power supply requirements stated on the NHB32-C’s rear panel. Use the supplied retaining clamp to secure the power cord, preventing inadvertent disconnection. Warning: Turn off all equipment connected to the NHB32-C before making any power connections. C MIDI OUT/IN ports These standard MIDI IN and OUT ports are used to connect MIDI devices for MIDI data transmission via CobraNet’s Serial Bridge. Program Change and Control Change messages can be transmitted over the Serial Bridge, however, it’s not suitable for time-sensitive performance data such as MIDI Note On/Off. D PRIMARY & SECONDARY CobraNet ports These RJ-45 ports are used to connect the NHB32-C to the primary and secondary CobraNet networks. Straight 100Base-TX CAT5 Ethernet cables should be used to connect the NHB32-C to a CobraNet network. Use STP (Shielded Twisted Pair) cables to protect against electromagnetic interference. If necessary, two CobraNet devices can be connected together using a crossover 100Base-TX Ethernet cable. Straight and crossover cables are not interchangeable. E WORD CLOCK 75Ω ON/OFF termination switch This switch applies 75Ω termination to the WORD CLOCK IN. Normally this switch should be set to ON when a wordclock source is connected to the WORD CLOCK IN. The OFF setting is for use with wordclock source devices with special specifications. F WORD CLOCK OUT BNC This BNC connector outputs a wordclock signal. G WORD CLOCK IN BNC This BNC connector is for connecting an external wordclock signal. The wordclock source is selected by using the wordclock source button on the front panel. ACU16-C & NHB32-C Owner’s Manual Rear Panel 29 This 9-pin male D-sub port is used to connect a Yamaha AD824 A/D converter. Control signals from a supporting device, such as the Yamaha DME32 Digital Mixing Engine or Yamaha DM2000 Digital Production Console, can be transmitted via CobraNet’s Serial Bridge. The COM port is an RS-422 serial interface, supporting cable runs of up to 1 kilometer. I TO COMPUTER port This 9-pin male D-sub port is used to connect the NHB32-C to a COM port on a PC running NetworkAmp Manager. It’s an RS-232C serial interface, supporting cable runs of up to 15 meters. The front panel USB port offers an alternative method of connection. The PC port to be used for communication with the NHB32-C is set in NetworkAmp Manager. J AES/EBU 1–4 I/O connectors These four 25-pin female D-sub connectors are used to input and output up to 64 channels of AES/EBU format digital audio. Each connector handles eight ins and eight outs. AES/EBU inputs and outputs are assigned to CobraNet audio channels in NetworkAmp Manager. Cable Length & Switching Hubs The maximum cable length for 100Ba-se-T Ethernet networks is 100 meters (2 kilometers with fiber optic cables). However, depending on the type of cable, switching hub, ACU16-C/NHB32-C’s workload, etc., reliable operation with this length of cable cannot be guaranteed. In addition, although about three or four switching hubs can be connected to a network, the actual number will depend on the efficiency of each switching hub.

The ID is set using the power amplifier’s rear panel AMP ID DIP switch, which consists of six individual switches, five for setting the ID, one for turning on and off termination (marked “T”). The five switches are individually numbered. IDs are set using a combination of switches to achieve the required ID. For example, to set ID #7, you’d set switches 4, 2, and 1 to the ON position (i.e., 4+2+1=7). To set ID #25, you’d set switches 16, 8, and 1 to the ON position (i.e., 16+8+1=25). To set ID #0, all switches should be set to OFF. On the last power amplifier in the RS-485 daisy-chain, the “T” switch should be set to ON to enable termination.

Cannot establish a connection with NetworkAmp Manager? Advice Make sure that the power cord is connected to a suitable AC wall outlet. Also make sure that the other end of the power cord is connected to the unit’s AC IN correctly. Use the supplied retaining clamp to ensure that the power cord cannot be disconnected inadvertently. Make sure that the POWER switch is set to the ON position. If you still cannot turn on the unit, contact your Yamaha dealer. Make sure the unit is powered up and that NetworkAmp Manager is running properly on your PC. Have you installed the necessary Yamaha USB or CBX driver? See “NetworkAmp Manager Installation” on page 10. In NetworkAmp Manager, choose General Setup from the Option menu and make sure that the correct MIDI driver is selected. If you are using a USB connection, this should be “YAMAHA USB.” If you are using an RS-232C serial connection, it should be “YAMAHA CBX Driver.” If you have used NetworkAmp Manager with a USB connection, while the USB cable is still connected, even if you select the “Yamaha CBX Driver,” a serial connection will not work unless the USB cable is disconnected. Check the USB or RS-232C serial cable connections as appropriate. If you are connecting to an NHB32-C, be sure to connect to the TO COMPUTER port, not the COM port. If you are using a USB connection, make sure that your PC’s USB port is working correctly. In Windows, open the System control panel and click the Device manager tab. See your Windows documentation for further information. ACU16-C NHB32-C Connected the unit to a CobraNet network and the CONDUCT and ERROR indicators light instead of the LINK indicator? If you are using an RS-232C serial connection, make sure that your PC’s serial port is working correctly. In Windows, open the System control panel and click the Device manager tab. See your Windows documentation for further information. Make sure that all ACU16-Cs and NHB32-Cs are assigned exclusive unit IDs. It’s okay to use the same unit IDs for ACU16-Cs and NHB32-Cs. Make sure that all devices on the network are powered up. Make sure that the Ethernet cables are connected to the unit properly (i.e., check they’re not pushed in only half way). Try swapping the Ethernet cable with a known good cable. Try connecting the unit to another port on the hub. Try disconnecting other devices from the network one-by-one to determine if another device or Ethernet cable is at fault. CAT3 Ethernet cable will almost certainly cause problems, as will incorrectly wired cables, damaged cables, cables deformed by tight cable ties, and tightly bent cables. When making cables yourself, be sure to maintain the natural twist of the conductors as close to the connector as possible. More than 25 mm of untwisted cable can affect performance. The LINK indicator is lit, but digital audio cannot be transmitted or received? Make sure that your CobraNet devices are set to transmit and receive the correct bundles. Also check your audio connections, audio sources, and audio I/O to bundle assignments. The CONDUCT indicator never lights up? This is normal. The CONDUCT indicator lights up only when the unit is working as CobraNet conductor. This selection is made automatically and you don’t normally need to do anything. The ERROR and CONDUCT indicators light simultaneously? A CobraNet link cannot be established. Make sure that the switching hubs and other devices are properly connected and turned on. The LINK, CONDUCT, and ERROR indicators flash simultaneously? A system error has occurred. There maybe an incorrect setting on another device or the unit maybe faulty. See “System Errors” on page 37 for more information. The ERROR indicator flashes? Audio sounds distorted? ACU16-C & NHB32-C Owner’s Manual An error has occurred with the unit’s built-in CobraNet interface. Check the cable connections and settings of all devices on the network. If you cannot resolve the problem and the ERROR indicator keeps flashing, the unit maybe faulty, in which case you should contact your Yamaha dealer. Continuously distorted sound is most likely due to overloaded audio inputs and levels being too high. Intermittent audio clicks and pops may be network related. Check your Ethernet cables and other CobraNet devices. Also check your wordclock settings. System Errors ACU16-C NHB32-C NetworkAmp Manager Symptom Advice NetworkAmp Manager cannot control and monitor all power amps? Make sure that all power amps are powered up. Make sure that each power amp is assigned an exclusive amp ID. Check the RS-485 cable connection between each power amp. If a cable is not connected properly, or a cable is faulty, power amps further down the line will not be detected. Speaker output sounds out of phase? Check your Euro-block connector wiring at the ACU16-C and power amps. The LOCK indicator flashes continuously? This means that the NHB32-C cannot lock to the currently selected wordclock source. Check and correct the source, or select another. The PATCH number flashes continuously? This indicates that a patch other than the one recalled or stored last is selected. Recall the patch, or select the patch that was last recalled or stored in order to stop it flashing. Cannot display the PDF format help document? Have you installed Acrobat Reader? See the ACU16-C/NHB32-C Owner’s Manual for details. System Errors When a system error occurs, the LINK, CONDUCT, and ERROR indicators flash simultaneously in a repeating patttern. You can determine the type of error by counting the number of flashes. There’s a two second pause between each series of flashes, as shown in the following illustration. Number of flashes 1 2 N 0.5 second (approx.) flash cycle - - - 1 2 N - - - 1 2 N 2 second pause Number of Flashes Symptom & Advice 2 Two or more units are set to the same ID. Make sure that all units are assigned an exclusive ID. 3 Some NHB32-Cs are in COM mode, some are in MIDI mode. On NetworkAmp Manager’s COM/MIDI dialog box, cancel COM/MIDI mode, and then set as required. 4 Three or more NHB32-Cs are in either COM or MIDI mode. On NetworkAmp Manager’s COM/MIDI dialog box, cancel COM/MIDI mode, and then set the required mode for two NHB32-Cs. 6 One or more ACU16-C/NHB32-C units have experienced an internal memory read error. Check the error messages in NetworkAmp Manager to determine which units are affected. The units maybe faulty, in which case you should contact your Yamaha dealer. 7 One or more ACU16-C/NHB32-C units have experienced an internal memory write error.
