EMX660—Owner’s Manual
Precautions
• Do not allow water to enter this unit or allow the
unit to become wet. Fire or electrical shock may
result.
• Connect this units power cord only to an AC
outlet of the type stated in this Owner’s Manual
or as marked on the unit. Failure to do so is a fire
and electrical shock hazard.
• Do not scratch, bend, twist, pull, or heat the
power cord. A damaged power cord is a fire and
electrical shock hazard.
• Do not place heavy objects, including this unit,
on top of the power cord. A damaged power cord
is a fire and electrical shock hazard. In particular,
be careful not to place heavy objects on a power
cord covered by a carpet.
• If you notice any abnormality, such as smoke,
odor, or noise, or if a foreign object or liquid gets
inside the unit, turn it off immediately. Remove
the power cord from the AC outlet. Consult your
dealer for repair. Using the unit in this condition
is a fire and electrical shock hazard.
• Should this unit be dropped or the cabinet be
damaged, turn the power switch off, remove the
power plug from the AC outlet, and contact your
dealer. If you continue using the unit without
heeding this instruction, fire or electrical shock
may result.
• If the power cord is damaged (i.e., cut or a bare
wire is exposed), ask your dealer for a replace-
ment. Using the unit with a damaged power cord
is a fire and electrical shock hazard.
• Do not remove the unit’s cover. You could receive
an electrical shock. If you think internal inspec-
tion, maintenance, or repair is necessary, contact
your dealer.
• Do not modify the unit. Doing so is a fire and
electrical shock hazard.
• When rack-mounting the unit, allow enough free
space around the unit for normal ventilation.
This should be: 30 cm at the sides, 30 cm behind,
and 40 cm above.
For normal ventilation during use, remove the
rear of the rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat
up inside and may cause a fire.
• This unit has ventilation holes at the rear to pre-
vent the internal temperature rising too high. Do
not block them. Blocked ventilation holes are a
fire hazard.
• Clean the contacts of the phone plug before con-
necting it to the SPEAKERS jack of this unit.
Dirty contacts may generate heat.
• Use only speaker cables when connecting speak-
ers to amplifier outputs. Using other types of
cables is a fire hazard.
Hold the power cord plug when disconnecting it
from an AC outlet. Never pull the cord. A dam-
aged 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.
• The digital circuits of this unit may induce a
slight noise into nearby radios and TVs. If noise
occurs, relocate the affected equipment.
• Using a mobile telephone near this unit may
induce noise. If noise occurs, use the telephone
away from the unit.
• XLR-type connectors are wired as follows: pin 1:
ground, pin 2: hot (+), and pin 3: cold (-).
• Do not set all equalizer controls and faders to
maximum. Doing so may cause oscillation
depending on the condition of the connected
unit and speakers, and may damage the speakers.
• The performance of components with moving
contacts, such switches, rotary controls, faders,
and connectors, deteriorates over time. The rate
of deterioration depends on the operating envi-
ronment and is unavoidable. Consult your dealer
about replacing defective components.

Front and rear panel
Control panel
Channel section
In this section, you can adjust equalization (fre-
quency response), volume level, effect and moni-
tor output levels for the input signal of each
channel.
1
Equalizer controls (HIGH, MID, LOW)
This is a 3-band equalizer that adjusts the high
frequency range, mid frequency range, and low
frequency range of each channel. Response is flat
when the knobs are in the
position. Rotating it
toward the right will boost the corresponding fre-
quency band, and rotating it toward the left will
cut it.
The base frequency (or center frequency), range
of boost or cut, and equalizer type of each band
are as follows.
HIGH: 12 kHz ±15 dB shelving type
MID: 2.5 kHz ±15 dB peaking type
LOW: 80 Hz ±15 dB shelving type
2
Monitor controls (MONI)
For each channel, this controls the amount of sig-
nal that is sent to the MONITOR bus.
The signal of the MONITOR bus is sent to the
speakers connected to the POWER AMP 2 A/B
jacks (only if the power amp select switch is in the
MAIN-MONITOR position) and to the MONI-
TOR jacks (input/output panel
6
).
3
Effect control (EFFECT)
For each channel, this controls the amount of sig-
nal that is sent to the EFFECT bus.
The signal of the EFFECT bus is sent to the built-
in effect and to the EFFECT OUT jacks (input/
output panel
3
).
4
Level control (LEVEL)
This adjusts the output level for each channel.
5
Pad switch (PAD) (Channel 1–4 only)
This switch attenuates the input signal by 30 dB.
When connecting a line level device to channels
1–4, or if the mic input is distorted, turn this
switch on (the pressed-in position).

each channel. This means that it will not be af-
fected by the setting of the LEVEL control.
Note:
The signal is sent to the EFFECT bus
from a location after the level control (
4
) of
each channel. This means that the amount of
signal that is sent to the EFFECT bus will be af-
fected not only by the setting of the effect con-
trol, but also by the setting of the level control.

DIGITAL EFFECT ON switch and indicator
When this switch is on (pressed), the indicator
lights up and the built-in digital effect can be
used. In that case, the signal processed by the dig-
ital effect will be sent to the MAIN/MONITOR
bus. The mix level of the effect sound is adjusted
by the EFFECT RTN control of the MAIN and
MONITOR sections.
MONITOR section
This section allows you to adjust the tone and
volume of the MONITOR bus, and specify the
mix level of the built-in effect and the external
input signals.
8
Graphic equalizer
This is a 7-band graphic equalizer that allows you
to adjust the frequency response of the MONI-
TOR bus signal, providing a maximum of ±12 dB
of cut/boost for each frequency band. You can use
these sliders to reduce the level of frequency
bands at which feedback easily occurs. Frequency
response is flat when a slider is in the center posi-
tion. Moving a slider in the positive direction will
boost, and in the negative direction will cut.
This graphic equalizer affects both the MONI-
TOR bus signal that is output to the speakers and
the line level signal which is output from the
MONITOR jack (input/output panel
6
).

Hi-Z, Lo-Z input jacks
These are the input jacks for channels 1–4. By
using the PAD switches (control panel
5
) you
can connect any of the jacks to a wide range of
sources from mics to line level devices (synthesiz-
ers or rhythm boxes etc.). The Lo-Z jacks can
provide +15 V phantom power, allowing you to
use condenser microphones.
Both Hi-Z and Lo-Z are balanced, and are com-
patible with microphones of output impedance
50–600
or line level devices of 600
. The nom-
inal input level is –40 dB – –10 dB for the Hi-Z
jacks, and –50 dB – –20 dB for the Lo-Z jacks.
Pin connections for the Hi-Z and Lo-Z jacks are
as follows.
2
MIC, LINE, INST input jacks
These are the input jacks for channels 5–6.
Microphones can be connected to the MIC jacks,
and stereo line level devices (such as synthesizers
or rhythm boxes) can be connected to the LINE
jacks.
The MIC jacks are balanced, and are compatible
with microphones of output impedance 50–
600
.
The LINE
1
&
2
jacks are unbalanced, and are
compatible with line level devices of 600
output
impedance. These two input jacks can be used
simultaneously.
Nominal input level is –50 dB for the MIC jacks
and –10 dB for the LINE jacks.
INST 1 & 2 jacks are unbalanced, can be used
simultaneously, and their high input impedance
makes them ideal for use with instruments such
as electric-acoustic guitar and electric bass. They
can also be used with line-level sources, such as
synthesizers and drum machines. Nominal input
level is –30 dB.
3 Effect output jack (EFFECT OUT)
The input of an external effect such as a delay or
echo can be connected to this jack.
The signal adjusted by the EFFECT control of
each channel will be sent to the EFFECT bus, and
output from this jack.
The nominal output level and impedance are
+4 dB/10 k.
4 Foot switch jack (FOOT SW)
A separately sold Yamaha FC5 foot switch can be
connected to this jack. If a foot switch is con-
nected to this jack, you can use your foot to

Installation/Connection
Installation
The EMX660 uses a forced cooling system with intake on the bottom of the rear panel and exhaust on the top
of the rear panel to avoid blocking the heated air flow.
Connection
When connecting various devices, be sure to use cables and plugs of the appropriate standard.
Speaker connection
There are three ways in which speakers can be connected to the EMX660.
1 Two-channel connection — A single speaker each can be connected to either the A or the B jack of POWER
AMP 1 and of POWER AMP 2.
2 Two-channel parallel connection — Two speakers can be connected in parallel to both the A and B jacks of
POWER AMP 1 and of POWER AMP 2.
3 Bridge connection — A single speaker can be connected to the BRIDGE jack.
For each of these, the required speaker impedance will differ. Refer to the following diagram, and make sure
that the speaker impedance is not less than the specified value.

Basic Operation
This section explains basic operation of the EMX660.
Connecting microphones
and instruments
1 Before connecting mics or instruments,
make sure that the power of all equip-
ment (where applicable) is turned off.
Also make sure that the level controls of
each channel of the EMX660 and the
MASTER control of the MAIN section are
turned down.

ments, and insert the other end of the
cable firmly into the appropriate Lo-Z/Hi-
Z jack (channels 1–4) or the MIC jack
(channels 5–6), LINE jack (channels 5),
INST jack (channels 6).
3 Turn the power on in the order of periph-
eral devices EMX660.
4 Set the MAIN section MASTER control to
the
position.
5 While speaking into the mic (while play-
ing the instrument), adjust the channel
LEVEL control so that the 0 LED of the
MAIN section peak level meter lights
occasionally.
Repeat this step for each channel.
6 If you wish to adjust the tone of each
channel, rotate the equalizer controls as
desired.
7 Use the MAIN section graphic equalizer
to adjust the tone.
8 Use the MAIN MASTER control to adjust
the overall volume.
Monitoring
By connecting a powered monitor speaker to the
MONITOR OUTPUT, you can create a monitor
mix independent of the MAIN mix, since the
input channel MONI controls are not affected by
the LEVEL controls.
1 Set the MONI MASTER control to the
position.
2 While speaking into a connected mic, or
playing a connected instrument, adjust
the MONI control of the input channel
that you want to monitor.
Repeat this procedure for each channel.
3 Use the MONI MASTER control to set the
overall level of the monitor mix.
Using the digital effect
The EMX660 has a built-in digital effect, allow-
ing reverberation or ambiance to be added to
vocals or instrumental sounds.
1 Press the DIGITAL EFFECT ON switch of
the DIGITAL EFFECT section.
2 Use the effect select switches of the DIGI-
TAL EFFECT section to select the effect
type.
VO.ECHO 1, 2 .....Echo appropriate for vocals.
VO.REV. 1, 2........Reverb appropriate for vocals.
HALL 1, 2 .............Reverb typical of a hall.
ROOM..................Reverb typical of a room.
PLATE .................Plate echo-like reverberation
3 Set the MAIN EFFECT RTN control to the
position.
4 Raise the EFFECT control of the channels
to which you wish to apply the digital
effect.
5 Use the MAIN/MONITOR section EFFECT
RTN control to adjust the level of the
sound processed by the effect.
Note: When connecting a line level device to
channels 1–4, turn on the PAD switch.
You cannot use a channel’s Lo-Z and Hi-Z jacks
at the same time. The MIC and LINE jacks, or
the MIC and INST jacks, however, can be used
at the same time.
Note: When turning the power off, reverse this
sequence.
Note: If the effect sound is distorted even if the
EFFECT RTN turned all the way down, lower
the EFFECT controls of each channel.

As a band PA 15
EMX660—Owner’s Manual
As a band PA
Here is an example of using the EMX660 as a small PA for a band. In this example, the monitor speakers are
being sent a mix that is independent of the MAIN speaker mix. An external effect such as delay or reverb is
also being used.
Connections
• Connect mics or instruments, such as keyboards,
to the channel input jacks 1–6.
• Connect the main speakers to the POWER AMP
1 A/B jacks, and connect the monitor speakers to
the POWER AMP 2 A/B jacks.
• If you will be using an external effect such as
delay or reverb, connect the EMX660’s EFFECT
OUT jack to the input jack of the external effect,
and connect the output jack of the external effect
to the EMX660’s AUX IN jack.
Note: Set the power amp select switch of the POW-
ER AMP section to the “MAIN MONITOR” posi-
tion. If you are using an external effect, we
recommend that you turn down the EFFECT RTN
controls of the MAIN and MONITOR sections. If
the external effect has a stereo output, it is possible
to connect its output jacks to the LINE jacks of
channels 5. However in this case, be sure that the
EFFECT controls are turned all the way down for
the channels into which the effect sound is being in-
put. If the EFFECT controls are raised, feedback will
occur, and your speakers may be damaged.

*1. Although this example shows an
external effects processor and foot-
switch, which is used to turn on and
off the built-in digital effects process-
or, connected to the EMX660, in
practice, only one effects processor,
internal or external, will be used at a
time, so the footswitch is not required
when using external effects.

Sending an independent mix to the
monitor speakers
1 Set the MONITOR section MASTER con-
trol to the
position.
2 Raise the MONI controls for the channels
that you wish to hear from the monitor
speakers.
3 Use the graphic equalizers and MASTER
controls of the MAIN/MONITOR sections
to adjust the overall volume and tone.
Using an external effect
1 Raise the EFFECT controls for the channels
to which you want the external effect to
be applied.
2 Adjust the input level of the external
effect so that the sound is not distorted at
the input of the external effect.
3 Use the MAIN section AUX IN control to
adjust the level of the sound processed by
the effect.
Note: The MONI controls are not affected by
the level settings of each channel. This allows
you to create a mix that is independent of the
MAIN section.
Troubleshooting 17
EMX660—Owner’s Manual
Troubleshooting
The following table describes the possible malfunctions of this device, and the appropriate actions to be taken in
each case.
Problem Cause Action
Sound is no
longer out-
put from the
speakers.
The POWER
indicator is
dark.
The load on this device was too great,
and the protection circuit for the inter-
nal transformer has operated. Possi-
ble reasons for the excessive load are
an excessive input to the device, or inap-
propriate ventilation.
Please wait. When the device cools off, normal
operation will resume automatically. However,
please check the following two points to prevent the
problem from recurring.
If the input to this device is greater than the nominal
level, lower the input to the nominal level. If the
device is not ventilated sufciently, refer to the cau-
tions given at the beginning of this manual and take
appropriate measures to insure adequate ventila-
tion.
The POWER
indicator is lit.
The load on the amplier of this device
was too great, and the protection cir-
cuit for the amplifier has operated.
Possible reasons for the excessive load
are an excessive level setting in the
channel control section or main section,
insufcient ventilation, or insufcient
load impedance of the connected speak-
ers.
Please wait. When the device cools off, normal
operation will resume automatically. However,
please check the following three points to prevent
the problem from recurring.
If the level setting is excessive, lower it to the nomi-
nal level. You can refer to the peak level indicators
of the main section when doing so.
If the device is not ventilated sufciently, refer to the
cautions given at the beginning of this manual and
take appropriate measures to insure adequate ven-
tilation.
If the load impedance (including a short) is too low,
refer to the chapter on connections (page 11) and
change the connections so that the impedance is
correct.
Other
Connections between devices have
come loose.
Inspect the connections, and correct any faulty con-
nections.

Response is flat when the knobs are in the ▼ position. Rotating it toward the right will boost the corresponding frequency band, and rotating it toward the left will cut it. The base frequency (or center frequency), range of boost or cut, and equalizer type of each band are as follows. HIGH: 12 kHz ±15 dB shelving type MID: 2.5 kHz ±15 dB peaking type LOW: 80 Hz ±15 dB shelving type EMX660—Owner’s Manual For each channel, this controls the amount of signal that is sent to the MONITOR bus. The signal of the MONITOR bus is sent to the speakers connected to the POWER AMP 2 A/B jacks (only if the power amp select switch is in the MAIN-MONITOR position) and to the MONITOR jacks (input/output panel 6). +15 MID 5 2 Monitor controls (MONI) Note: The signal is sent to the MONITOR bus from a location before the level control (4) of each channel. This means that it will not be affected by the setting of the LEVEL control. 3 Effect control (EFFECT) For each channel, this controls the amount of signal that is sent to the EFFECT bus. The signal of the EFFECT bus is sent to the builtin effect and to the EFFECT OUT jacks (input/ output panel 3). Note: The signal is sent to the EFFECT bus from a location after the level control (4) of each channel. This means that the amount of signal that is sent to the EFFECT bus will be affected not only by the setting of the effect control, but also by the setting of the level control. 4 Level control (LEVEL) This adjusts the output level for each channel. 5 Pad switch (PAD) (Channel 1–4 only) This switch attenuates the input signal by 30 dB. When connecting a line level device to channels 1–4, or if the mic input is distorted, turn this switch on (the pressed-in position). 5 Control panel ■ DIGITAL EFFECT section ■ MONITOR section This section allows you to turn the built-in digital effect on/off and to select the effect type. This section allows you to adjust the tone and volume of the MONITOR bus, and specify the mix level of the built-in effect and the external input signals. 8 VO. ECHO 1 VO. ECHO 2 VO. REV. 1 VO.

The indicator of the selected effect type lights up. 7 DIGITAL EFFECT ON switch and indicator When this switch is on (pressed), the indicator lights up and the built-in digital effect can be used. In that case, the signal processed by the digital effect will be sent to the MAIN/MONITOR bus. The mix level of the effect sound is adjusted by the EFFECT RTN control of the MAIN and MONITOR sections. This is a 7-band graphic equalizer that allows you to adjust the frequency response of the MONITOR bus signal, providing a maximum of ±12 dB of cut/boost for each frequency band. You can use these sliders to reduce the level of frequency bands at which feedback easily occurs. Frequency response is flat when a slider is in the center position. Moving a slider in the positive direction will boost, and in the negative direction will cut. This graphic equalizer affects both the MONITOR bus signal that is output to the speakers and the line level signal which is output from the MONITOR jack (input/output panel 6). 9 EFFECT RTN control This controls the level of the effect sound which is returned from the built-in digital effect to the MONITOR bus. 0 TAPE IN control This controls the level of the signal routed from the TAPE IN jack to the MONITOR bus. A MASTER control This adjusts the final level of the MONITOR bus. It affects both the MONITOR bus signal which is output to the speakers and the line level signal which is output to the MONITOR jack (input/ output panel 6). B Peak level indicator This indicator allows you to monitor the level of the signal which is output from the MONITOR jack (input/output panel 6). Note: To avoid distortion, adjust the MASTER control (A) so that the 0 indicator lights occasionally.

Microphones can be connected to the MIC jacks, and stereo line level devices (such as synthesizers or rhythm boxes) can be connected to the LINE jacks. The MIC jacks are balanced, and are compatible with microphones of output impedance 50– 600Ω. The LINE 1 & 2 jacks are unbalanced, and are compatible with line level devices of 600Ω output impedance. These two input jacks can be used simultaneously. Nominal input level is –50 dB for the MIC jacks and –10 dB for the LINE jacks. INST 1 & 2 jacks are unbalanced, can be used simultaneously, and their high input impedance makes them ideal for use with instruments such as electric-acoustic guitar and electric bass. They can also be used with line-level sources, such as synthesizers and drum machines. Nominal input level is –30 dB. Note: It is possible to simultaneously use both the MIC and LINE inputs for channel 5, and the MIC and INST inputs for channel 6. + Note: It is not possible to simultaneously use both the Hi-Z and Lo-Z inputs of a given channel. For each channel, use only one of the inputs as appropriate for the input source. Phantom power is switched on/off in simultaneously for the Lo-Z jacks of channels 1–4 and the MIC jacks of channels 5–6. For this reason, any devices other than condenser microphones must be connected to the Hi-Z or LINE jacks if the PHANTOM switch (control panel L) is on. EMX660—Owner’s Manual 1 2 MIC, LINE, INST input jacks These are the input jacks for channels 1–4. By using the PAD switches (control panel 5) you can connect any of the jacks to a wide range of sources from mics to line level devices (synthesizers or rhythm boxes etc.). The Lo-Z jacks can provide +15 V phantom power, allowing you to use condenser microphones. Both Hi-Z and Lo-Z are balanced, and are compatible with microphones of output impedance 50–600Ω or line level devices of 600Ω. The nominal input level is –40 dB – –10 dB for the Hi-Z jacks, and –50 dB – –20 dB for the Lo-Z jacks. Pin connections for the Hi-Z and Lo-Z jacks are as follows. Lo-Z jacks (XLR type) EEEngine 1 3 Effect output jack (EFFECT OUT) The input of an external effect such as a delay or echo can be connected to this jack. The signal adjusted by the EFFECT control of each channel will be sent to the EFFECT bus, and output from this jack. The nominal output level and impedance are +4 dB/10 kΩ. 4 Foot switch jack (FOOT SW) A separately sold Yamaha FC5 foot switch can be connected to this jack. If a foot switch is connected to this jack, you can use your foot to switch the built-in digital effect on/off. Input/output panel 9 5 External input jacks (AUX IN/TAPE IN) These are input jacks that allow the signal from an external device to be added to the MAIN output. Monaural output devices such as external effects can be connected to the AUX IN jack, and stereo output devices such as cassette recorder or CD players can be connected to the TAPE IN jacks. The nominal input level and impedance are –10 dB/ 600Ω for the AUX IN jack, and –10 dBV/600Ω for the TAPE IN jacks. 6 External output jacks (REC OUT/MONITOR/MAIN) These are output jacks which send line level signals from the EMX660 to external devices. A stereo recording device such as a cassette deck, DAT or MD recorder can be connected to the REC OUT jacks, and a playback device such a power amp can be connected to the MONITOR and MAIN jacks. The signals sent from each jack are as follows. • REC OUT jacks: The MAIN bus signal before it has passed through the MASTER control and graphic equalizer • MONITOR jack: The MONITOR bus signal which has passed through the Monitor MASTER control and graphic equalizer • MAIN jack: The MAIN bus signal which has passed through the Main MASTER control and graphic equalizer The nominal output level and impedance are –10 dBV/10 kΩ for the REC OUT jacks, and +4 dB/10 kΩ for the MONITOR/MAIN jacks. EMX660—Owner’s Manual 10 Front and rear panel Rear panel 2 POWER ON / OFF 1 Speaker output jacks (POWER AMP 1 A/B, POWER AMP 2 A/B, BRIDGE) Speakers can be connected to these jacks. The EMX660 contains a two-channel power amp, and there are three ways in which the speakers can be connected to the EMX660. At this time, use the power amp select switch J on the control panel to select a signal sent to the correct jacks. ■ When the power amp select switch is set to MAIN-MONITOR or MAIN-MAIN: • Two-channel connection Two 4–8Ω speakers can be connected to the A jack or B jack of the POWER AMP 1/2 (maximum output 300W+300W). • Two-channel parallel connection Two 8–16Ω speakers can be connected to the POWER AMP 1 A/B jacks and two more to the POWER AMP 2 A/B jacks, for a total of four speakers (maximum output 300 W+300 W). ■ When the power amp select switch is set to MAIN-BRIDGE (Bridge connection) • One 8–16Ω speaker can be connected to the BRIDGE jack (maximum output 600 W).

Although this example shows an external effects processor and footswitch, which is used to turn on and off the built-in digital effects processor, connected to the EMX660, in practice, only one effects processor, internal or external, will be used at a time, so the footswitch is not required when using external effects. EMX660—Owner’s Manual Normally, connect speakers to the jacks on the rear panel. If more speaker outputs are needed, use the MAIN (STEREO) jacks for stereo output and the MONITOR jack for monaural output. Basic Operation 13 Basic Operation This section explains basic operation of the EMX660. Connecting microphones and instruments 1 Before connecting mics or instruments, make sure that the power of all equipment (where applicable) is turned off. Also make sure that the level controls of each channel of the EMX660 and the MASTER control of the MAIN section are turned down. 2 Connect cables to your mics and instruments, and insert the other end of the cable firmly into the appropriate Lo-Z/HiZ jack (channels 1–4) or the MIC jack (channels 5–6), LINE jack (channels 5), INST jack (channels 6). Note: When connecting a line level device to channels 1–4, turn on the PAD switch. You cannot use a channel’s Lo-Z and Hi-Z jacks at the same time. The MIC and LINE jacks, or the MIC and INST jacks, however, can be used at the same time. 3 Turn the power on in the order of peripheral devices ➞ EMX660. Note: When turning the power off, reverse this sequence. 4 Set the MAIN section MASTER control to the √ position. 5 While speaking into the mic (while playing the instrument), adjust the channel LEVEL control so that the 0 LED of the MAIN section peak level meter lights occasionally. Repeat this step for each channel. 6 If you wish to adjust the tone of each channel, rotate the equalizer controls as desired. 7 Use the MAIN section graphic equalizer to adjust the tone. 8 Use the MAIN MASTER control to adjust the overall volume. Monitoring By connecting a powered monitor speaker to the MONITOR OUTPUT, you can create a monitor mix independent of the MAIN mix, since the input channel MONI controls are not affected by the LEVEL controls. 1 Set the MONI MASTER control to the √ position. 2 While speaking into a connected mic, or playing a connected instrument, adjust the MONI control of the input channel that you want to monitor. Repeat this procedure for each channel. 3 Use the MONI MASTER control to set the overall level of the monitor mix. Using the digital effect The EMX660 has a built-in digital effect, allowing reverberation or ambiance to be added to vocals or instrumental sounds. 1 Press the DIGITAL EFFECT ON switch of the DIGITAL EFFECT section. 2 Use the effect select switches of the DIGITAL EFFECT section to select the effect type. VO.ECHO 1, 2 .....Echo appropriate for vocals. VO.REV. 1, 2........Reverb appropriate for vocals. HALL 1, 2 .............Reverb typical of a hall. ROOM ..................Reverb typical of a room. PLATE .................Plate echo-like reverberation 3 Set the MAIN EFFECT RTN control to the √ position. 4 Raise the EFFECT control of the channels to which you wish to apply the digital effect. 5 Use the MAIN/MONITOR section EFFECT RTN control to adjust the level of the sound processed by the effect. Note: If the effect sound is distorted even if the EFFECT RTN turned all the way down, lower the EFFECT controls of each channel.

Although this example shows an external effects processor and footswitch, which is used to turn on and Footswitch off the built-in digital effects process(YAMAHA FC5) or, connected to the EMX660, in practice, only one effects processor, internal or external, will be used at a time, so the footswitch is not required when using external effects. EMX660—Owner’s Manual 16 Example setups Sending an independent mix to the monitor speakers 1 Set the MONITOR section MASTER control to the √ position. 2 Raise the MONI controls for the channels that you wish to hear from the monitor speakers. Note: The MONI controls are not affected by the level settings of each channel. This allows you to create a mix that is independent of the MAIN section. 3 Use the graphic equalizers and MASTER controls of the MAIN/MONITOR sections to adjust the overall volume and tone. EMX660—Owner’s Manual Using an external effect 1 Raise the EFFECT controls for the channels to which you want the external effect to be applied. 2 Adjust the input level of the external effect so that the sound is not distorted at the input of the external effect. 3 Use the MAIN section AUX IN control to adjust the level of the sound processed by the effect.
