Main Features
D-PRE and High-Quality Operational Amplifiers
Mono input channels are equipped with “D-PRE” Class-A discrete microphone preamplifiers. The D-PRE head amplifier
features an inverted Darlington circuit used in high-end audio devices. This circuit uses multi-stage amplifying elements to
ensure high current and low impedance, for an audio texture with crispness and richness in the low and mid frequencies.
Combined with the specially-designed “MG01” operational amp, the overall result is full-bodied reproduction of low fre-
quencies as well as sustained high frequencies. Input channels feature combo jacks, which can accept both XLR and TRS
connectors. In addition, PAD circuitry allows line level input, to accommodate a wide variety of instruments.
Improved Convenience with Built-in Universal Switching Power Supply
The MG series features a universal switching power supply. This power supply supports input voltages of 100 V to 240 V,
for stable operation even in environments where power voltage fluctuates easily. Lowering the impedance of the power sup-
ply has resulted in improved sound quality with a faster attack. An AC inlet allows simple installation in environments
where portability is required, as well as when mounting the mixing console in a rack.
24 High-Quality Digital Effects (XU Models)
The XU models (MG20XU/MG16XU/MG12XU) feature 24 built-in effects that are based on SPX algorithms used by pro-
fessionals. In particular, the high-quality reverb and delay expand the spatial quality of the sound with remarkable realism
and naturalness.
24-bit/192 kHz USB Audio Interface (XU Models)
The XU models (MG20XU/MG16XU/MG12XU) feature a USB 2.0 audio interface capable of 24-bit/192 kHz sound qual-
ity. With the audio interface you can play back music from your computer, or use DAW software such as Cubase AI to
record the mixer output. The XU models support USB Audio Class 2.0 so you can use them with USB Audio Class 2.0
compliant tablets and other devices, without the need to install drivers. The USB protocol uses asynchronous data transfer.
Audio data is transferred based on a highly precise audio clock signal from the MG, for high quality recording and play-
back.

Quick Start Guide
We’ll begin this guide by connecting a pair of speakers and generating some stereo output. Note that the operations
and procedures will vary somewhat according to the input devices you are using.
Step 1 Preparing the Power Sup-
ply
1. Make sure that the power switch of the unit is
set to the “ ” position (off).
2. Connect the socket of the included power cord
to the [AC IN] jack on the rear panel.
3. Plug the power cord into a power outlet.
Step 2 Making Connections
1. Turn all the faders and [GAIN] knobs com-
pletely down.
2. Connect the microphones, instruments, and/or
speakers you intend to use.
For details on making connections, see “Setup Examples”
(pages 12 – 13), “Front Panel” and “Rear Panel” (pages 14 –
15).
Step 3 Powering Up the System
To prevent an unwanted burst of noise from the
speakers, power up the devices in the following
order: peripheral devices (instruments, micro-
phones, etc.) mixing console power amps
(or powered speakers).
Reverse this order when turning the power off.
WARNING
Be sure to turn the power on/off in the order given in Step 3
above every time you use the mixer. Failure to do so may
result in loud noise bursts that can damage your equipment,
your ears, or both.
NOTICE
If you are using condenser microphones that require phantom
power, turn the mixer’s [PHANTOM +48V] switch on before
turning on the power to the power amps or powered speakers.
See page 17 for details. Also, read the details about the

Step 4 Getting Sound to the Speakers
1. Turn on ( ) the [PFL] switches for each chan-
nel you are using.
NOTE
• When you turn on the [PFL] switch for a channel, you can
monitor the signal for that channel through headphones con-
nected to the [Phones] jack. The level of the signal is also
shown on the level meter indicator, allowing you to more
accurately check signal levels. After checking levels, turn the
[PFL] switches off.
• When a [PFL] switch is turned on, the [PFL] indicator below
the level meter flashes.
2. While playing your instrument or speaking into
a microphone, adjust the input signal with the
[GAIN] knob until it goes past the “0” (<) posi-
tion on the level meter only occasionally.
NOTE
If you connect a portable audio player, synthesizer, or other
equipment to a stereo input channel that has no [GAIN] knob,
adjust the output level on the connected device.
3. Turn on ( ) the [ON] switches for each chan-
nel you are using.
4. Turn on ( ) the [ST] switches for each chan-
nel you are using.
5. Turn off ( ) all [PFL] switches.
Confirm that the [PFL] indicator below the level meter is off.
6. Turn on ( ) the [ON] switch for the [STEREO]
master.
7. Raise the [STEREO] master fader to the “0”
position.
8. Set the channel faders to create the desired
initial balance.
9. Adjust the overall volume of the [STEREO]
master fader.
The overall headphone level is adjusted by the [PHONES]
knob.
NOTE
If the level meter [PEAK] indicator lights frequently, slightly
lower the channel faders to avoid distortion.

Using Reverb and Delay
Your mixes can be further enhanced by using the built-in ambience effects such as reverb or delay.
Reverb and Delay Time
The optimum reverb time for a piece of music will depend on the music’s tempo and density, but as a general rule longer reverb times
are good for ballads, while shorter reverb times are more suited to up-tempo tunes. Delay times can be adjusted to create a wide vari-
ety of repeating rhythmic effects. When adding a delay to a vocal, for example, try setting the delay time to dotted eighth notes ( e. )
corresponding to the tune’s tempo.
Reverb Level
While working for many hours on a mix, your sense of hearing will start to dull slightly. This can lead to the perception that tracks with
excess processing sound like the perfect mix. To avoid falling into this trap, start with reverb level all the way down, then gradually bring
the reverb into the mix until you can just hear the difference. Any more than this normally becomes a special effect or, worse yet,
makes the sound muddy and indistinct. In general, you don’t want reverb to dominate the mix, so you should apply it judiciously.

r [PAD] switch
When this switch is turned on ( ), the input signal from
the [MIC/LINE] jack of the mono input channel is attenuated
by 26 dB. Turn this switch off ( ) if you’ve connected a
microphone or other device with a low input level to the
channel. Turn it on ( ) if you’ve connected a line-level
device.
NOTE
There may be some noise when operating switches. To prevent
this, turn the [ON] switch of a channel off before operating
other switches.
t [HPF] (High Pass Filter) switch
Turning this switch on ( ) will apply a high-pass filter that
attenuates frequencies below 80 Hz in the signal by a slope of
12 dB/octave.
NOTE
Turning the [HPF 80Hz (MIC)] switch on will apply a dedicated
high-pass filter only to the signal from the [MIC] jacks.
y [GAIN] knobs
For adjusting the gain of the input signal. Mono input chan-
nels have a [PAD] switch r that lets you change the range of
this control.
The adjustable gain range is as follows.
u [COMP] knobs
For adjusting the amount of compression applied to the chan-
nel. As the [COMP] knob is turned to the right the threshold,
ratio, and output gain are adjusted simultaneously.
• Threshold: +22 dBu to -8 dBu
• Ratio: 1:1 to 4 :1
• Output gain: 0 dB to +7 dB
• Attack time: Approximately 25 ms
• Release time: Approximately 300 ms
NOTE
Avoid setting the compression too high; since the resulting
higher average output level may lead to feedback.
i [PHANTOM +48V] switch and indicator
This switch toggles phantom power on and off. Turn this
switch on ( ) to supply DC+48 V to the XLR input jacks.
The indicator lights when this switch is on. Turn this switch

!0 Equalizer ([HIGH]/[MID]/[LOW])
Equalization Types and Characteristics
The equalizer shapes the high, mid, and low audio frequen-
cies. Turning the knob to the right amplifies (boosts) the cor-
responding frequency band, while turning it to the left
attenuates (cuts) the band. Setting the knob to the middle “t”
position produces a flat response in the corresponding band.
The upper knob sets the variable mid frequency, while the
lower knob sets the amount of attenuation or boost (counter-
clockwise/clockwise) for the range.
The following table shows the EQ type, frequency, and cut/
boost range for each of the three bands.
* The signals from mono input jacks of the MG20XU/MG20
and MG16XU/MG16 can be adjusted from 250 Hz to 5 kHz.
!1 [AUX 1 – 4] knobs
[PRE] switches
[AUX (2, 4)/FX] knobs
The levels of each signal sent to the AUX 1 –
4 buses from each channel can be adjusted
independently. On stereo input channels, the
Line L (odd) and Line R (even) input signals
are mixed before being sent to each AUX
bus. Adjust the knobs so that they are near or
at the “t” (nominal) position.
NOTE
• The [AUX1] knob indicated “PRE” adjusts the level of the pre-
fader signal (before fader adjustment).
• The [PRE] switch on [AUX1] and [AUX2] can be used to
select whether the pre-fader ( ) (the signal before fader
adjustment) or post fader ( ) (the signal after fader adjust-
ment) signal is sent to the AUX bus by the [PRE] switch.
• The [AUX4/FX] and [AUX2/FX] knobs are used to adjust the
level of the signal sent to the FX bus (built-in effects) in addi-
tion to the AUX bus. The same signal level is sent to the AUX
buses and FX buses connected to these knobs.
!2 [PAN] knobs
[PAN/BAL] knobs
[BAL] knobs
• PAN: Sets the position of the sound image within the
stereo field. This knob adjusts the volume bal-
ance of each channel sent to the STEREO L/R
bus. When the knob is set to the 12 o’clock posi-
tion, the channel’s sound will be sent to the L and
R of the STEREO L/R bus at the same volume. In
this case, the sound image is positioned at the
center. If the bus assign switch [1-2] or [3-4] is
pressed, this knob adjusts the volume balance
sent to the GROUP bus. When the knob is set to
the 12 o’clock position, the same volume is sent
to each GROUP bus. If the knob is turned com-
pletely to the left, the signal is sent to the GROUP
1 or GROUP 3 bus only; if the knob is turned
completely to the right, the signal is sent to the
GROUP 2 or GROUP 4 bus only.

• BAL: Sets the volume balance of the signal sent from
each stereo input channel (L/R) to the STEREO
L/R bus or GROUP bus. When this knob is set to
the 12 o’clock position, the sound of the stereo
input channels (L/R) will be sent to the STEREO
L/R bus or GROUP 1, 3/2, 4 bus at the same vol-
ume.
• PAN/BAL: This knob performs both [PAN] and [BAL]
functions. You can use this as a [PAN] control
when sound is input to the [LINE] (L/MONO) jack,
and as a [BAL] control when sound is input to
both the [LINE] (L) and [LINE] (R) jacks.
!3 [ON] switches
Turn this switch on ( ) to send the respective channel’s
signal to the buses. The switch lights when on. When this
switch is off ( ), the respective signal input is not sent to
the AUX bus or GROUP bus.

nel can still be monitored via the [PHONES] jack.
• To minimize noise, turn the [ON] switch off for any unused
channels.
!4 [PEAK] indicators
The peak level of the post-EQ signal is detected, and the
PEAK indicator lights red when the level reaches 3 dB below
clipping.
!5 Bus assign switch
These switches determine the bus(es) to which each channel’s
signal is sent. Turn the switch on ( ) to output the signal to
the corresponding buses.
• [1-2] switch: Assigns the channel’s signal to the
GROUP 1-2 buses.
• [3-4] switch: Assigns the channel’s signal to the
GROUP 3-4 buses.
• [ST] switch: Assigns the channel’s signal to the STE-
REO L/R buses.
NOTE
To send the signal to each bus, engage the [ON] switch !3.
!6 [PFL] (Pre-fader Listen) switch
When the [PFL] switch is on ( ), the channel pre-fader
signal is output to the [MONITOR OUT] and [PHONES]
jacks for monitoring. In this condition, the audio from the
STEREO L/R buses or GROUP buses that could be heard in
the [MONITOR OUT] and [PHONES] jacks can no longer be
heard. When a [PFL] switch is turned on, the [PFL] indicator
below the level meter flashes.
!7 Channel faders
For adjusting the level of the channel signal. Use these con-
trols to adjust the balance between the various channels.
NOTE
To minimize noise, set the fader sliders for any unused chan-
nels all the way down.

switches? Check that the power of that device is turned on.
No sound is output. Are external instruments (including microphones) and speakers connected correctly?
Are your cables shorted?
Are the [GAIN] knobs for each channel, channel faders, [STEREO] master fader, and [GROUP] fad-
ers adjusted to appropriate levels?
Are the bus assign switches and [LINE /USB ] switch set appropriately?
No sound is output from the
[STEREO OUT] jack.
Are the [ON] switch and [ST] switch for the channels you are using turned on?
Is the [STEREO] master [ON] switch turned on?
No sound is output from the
[SEND (AUX1 – 4)] jacks
Are the [SEND MASTER] knobs and [AUX 1 – 4] for each channel set appropriately?
Are the [ON] switches for the channels you are using turned on?
No sound is output from the
[MONITOR OUT] jack or
[PHONES] jack.
Are the [PFL] switches for the channels you are not using turned on?
Turn the [PFL] switches off.
The sound is low, distorted,
or noisy.
Is the microphone connected to a [MIC] jack or a [MIC/LINE] jack?
When using a condenser microphone, is the [PHANTOM +48V] switch turned on?
Is the [PAD] switch on? Turn this switch off for sources with low output levels, such as microphones.
Is the output signal level for the instrument connected to the mixer appropriate?
When connecting an instrument with an output level of +4 dBu, either turn on the [PAD] switch on a
mono input channel or use a stereo input channel.
Where an input channel provides both a XLR input jack and a phone input jack, or a phone input
jack and an RCA pin jack, are there connections made at both jacks? Use only one of these jacks.
Are the [GAIN] knobs for each channel, channel faders, [STEREO] master fader, and [GROUP] fad-
ers adjusted to appropriate levels?
Are effect or compressor levels too high? Use the [FX] knob, [FX RTN] fader, [FX RTN LEVEL]
knob, and [COMP] knob to lower their levels.
Effects are not applied. Are the [FX] knobs for each channel adjusted to appropriate levels?
Is the [ON] button for [FX RTN] turned on?
Are the [PARAMETER] knob and [FX RTN] fader adjusted to appropriate levels?
Is the [FX RTN] bus assign switch set appropriately?
If external effects are connected to the [SEND(AUX1 – 4)] jacks, are the [AUX1 – 4] knobs for
[SEND MASTER] set appropriately?
Speaking voices are not
clear.
Is the [HPF] switch turned on?
Is the equalizer ([HIGH]/[MID]/[LOW]) adjusted appropriately?
No mixer monitor signal is
output.
Are powered speakers connected to the [MONITOR OUT] jacks?
Use the [MONITOR LEVEL] knob to adjust the signal output from the [MONITOR OUT] jacks.
Left and right levels are dif-
ferent for a stereo signal
input.
Is [PAN] set to the center? If panned to the center, try reversing the left and right input connections.
If, after switching the left and right connections, the side with the low volume level also switches,
check the instrument or device that is the source of the signal.
Are you using the same type of cable to connect both the left and right input signals? Cables with
built-in resistors will attenuate the signal.
The sound level is unstable
and inconsistent.
Is the compressor level set too high? Use the [COMP] knob to lower the level.
The volume of audio play-
back from a computer need
to be adjusted.
Use the “Attenuator Function”. For details, see page 28.

XLR
This 3-pin connector is resistant to externally induced noise, and is used pri-
marily for balanced connections. With properly designed receiving circuitry,
cables with this type of connector can also be used for unbalanced signals.
XLR type connectors are the standard for microphone connections as well as
most professional audio gear.
Phone
Phone connectors are available in TRS and TS types. TRS types are used for
stereo headphone jacks, insert jacks, and also for carrying balanced signals in
many cases. TS types are used to carry unbalanced signals -for example,
electric guitar cables.
RCA Pin
This type of unbalanced connector is most commonly found on home audio
and video equipment. RCA type pin jacks are often color coded: white for left
audio channel and red for right audio channel, for example.

Rack Mounting
The MG12XU/MG12 require at least 10 U* of rack space. To take
into account the cable connections, we recommend to ensure 11
U* of rack space. The MG20XU/MG20/MG16XU/MG16 require
at least 12 U* of rack space. To take into account the cable con-
nections, we recommend to ensure 14 U* of rack space.
* 10 U is approximately 445 mm, 11 U is approximately 489 mm, 12
U is approximately 533 mm, and 14 U is approximately 623 mm.
Precautions for Rack Mounting
This unit is rated for operation at ambient temperatures
ranging from 0 to 40 degrees Celsius. If you install this unit
along with other devices in a poorly ventilated rack, the
ambient temperature inside the rack may rise, resulting in
inefficient performance. Be sure to rack-mount in the fol-
lowing conditions so the unit does not overheat.
• When mounting the unit in a rack with devices such as
power amplifiers that generate a significant amount of
heat, leave more than 1 U of space between the MG and
other equipment. Also, either leave the open spaces
uncovered or install appropriate ventilating panels to
minimize the possibility of heat buildup.
• To ensure sufficient airflow, leave the rear of the rack
open and position it at least 10 centimeters from walls or
other surfaces. If the rear of the rack cannot be left open,
install a commercially available fan or similar ventilating
option to secure sufficient airflow. If you’ve installed a
fan kit, there may be cases in which closing the rear of the
rack will produce a greater cooling effect. Refer to the
rack and/or fan unit manual for details.
Mounting Procedures
(The illustration shows the MG12XU.)
1. Use a screwdriver to loosen the screws on the
sides of the mixer (six total).
2. Use the screws removed in Step 1 to install the
rack-mount kit (included with MG20XU/MG20/
MG16XU/MG16, optional RK-MG12 for the
MG12XU/MG12 sold separately) on the mixer.
NOTICE
Be sure to use the screws removed in Step 1. Using other
screws can cause damage.
3. Mount the unit into the rack, and fasten it into
place.
CAUTION
This unit is heavy, and should be lifted by two people
when mounting it into a rack.
* The MG20XU/MG20/MG16XU/MG16 require at least 12 U of rack
space. To take into account the cable connections, we recom-
mend to ensure 14 U of rack space.

CAUTION Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the device or other property. These precautions include, but are not limited to, the following: Power supply/power cord • When removing the electric plug from the device or an outlet, always hold the plug itself and not the cord. Pulling by the cord can damage it. • Remove the electric plug from the outlet when the device is not to be used for extended periods of time, or during electrical storms. Location • Do not place the device in an unstable position where it might accidentally fall over. • Do not block the vents. This device has ventilation holes at the bottom/sides to prevent the internal temperature from becoming too high. In particular, do not place the device on its side or upside down. Inadequate ventilation can result in overheating, possibly causing damage to the device(s), or even fire. • Do not place the device in a location where it may come into contact with corrosive gases or salt air. Doing so may result in malfunction. • Before moving the device, remove all connected cables. • When setting up the device, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet. Even when the power switch is turned off, electricity is still flowing to the product at the minimum level. When you are not using the product for a long time, make sure to unplug the power cord from the wall AC outlet. • When rackmounting the device, always use two or more people. Attempting to lift the device by yourself may damage your back, result in other injury, or cause damage to the device itself. • If the device is mounted in an EIA standard rack, carefully read the section “Precautions for Rack Mounting” on page 35. Inadequate ventilation can result in overheating, possibly causing damage to the device(s), malfunction, or even fire. Connections • Before connecting the device to other devices, turn off the power for all devices. Before turning the power on or off for all devices, set all volume levels to minimum. MG20XU/MG20/MG16XU/MG16/MG12XU/MG12 Owner’s Manual 5 PA_en_2 2/2 Maintenance • Remove the power plug from the AC outlet when cleaning the device. Handling caution • Do not insert your fingers or hands in any gaps or openings on the device (vents). • Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any gaps or openings on the device (vents). If this happens, turn off the power immediately and unplug the power cord from the AC outlet. Then have the device inspected by qualified Yamaha service personnel. • Do not rest your weight on the device or place heavy objects on it, and avoid use excessive force on the buttons, switches or connectors. • Do not use speakers or headphones for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician. Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed. NOTICE To avoid the possibility of malfunction/damage to the product, damage to data, or damage to other property, follow the notices below. Handling and Maintenance • Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile phone, or other electric devices. Otherwise, the device, TV, or radio may generate noise. • Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components. • Do not place vinyl, plastic or rubber objects on the device, since this might discolor the panel. • When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths. • Condensation can occur in the device due to rapid, drastic changes in ambient temperature—when the device is moved from one location to another, or air conditioning is turned on or off, for example. Using the device while condensation is present can cause damage. If there is reason to believe that condensation might have occurred, leave the device for several hours without turning on the power until the condensation has completely dried out. • Avoid setting all equalizer controls and faders to their maximum. Depending on the condition of the connected devices, doing so may cause feedback and may damage the speakers. • Do not apply oil, grease, or contact cleaner to the faders. Doing so may cause problems with electrical contact or fader motion. • When turning on the AC power in your audio system, always turn on the power amplifier LAST, to avoid speaker damage. When turning the power off, the power amplifier should be turned off FIRST for the same reason. • Always turn the power off when the device is not in use. Connectors XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).

The D-PRE head amplifier features an inverted Darlington circuit used in high-end audio devices. This circuit uses multi-stage amplifying elements to ensure high current and low impedance, for an audio texture with crispness and richness in the low and mid frequencies. Combined with the specially-designed “MG01” operational amp, the overall result is full-bodied reproduction of low frequencies as well as sustained high frequencies. Input channels feature combo jacks, which can accept both XLR and TRS connectors. In addition, PAD circuitry allows line level input, to accommodate a wide variety of instruments. Improved Convenience with Built-in Universal Switching Power Supply The MG series features a universal switching power supply. This power supply supports input voltages of 100 V to 240 V, for stable operation even in environments where power voltage fluctuates easily. Lowering the impedance of the power supply has resulted in improved sound quality with a faster attack. An AC inlet allows simple installation in environments where portability is required, as well as when mounting the mixing console in a rack. 24 High-Quality Digital Effects (XU Models) The XU models (MG20XU/MG16XU/MG12XU) feature 24 built-in effects that are based on SPX algorithms used by professionals. In particular, the high-quality reverb and delay expand the spatial quality of the sound with remarkable realism and naturalness. 24-bit/192 kHz USB Audio Interface (XU Models) The XU models (MG20XU/MG16XU/MG12XU) feature a USB 2.0 audio interface capable of 24-bit/192 kHz sound quality. With the audio interface you can play back music from your computer, or use DAW software such as Cubase AI to record the mixer output. The XU models support USB Audio Class 2.0 so you can use them with USB Audio Class 2.0 compliant tablets and other devices, without the need to install drivers. The USB protocol uses asynchronous data transfer. Audio data is transferred based on a highly precise audio clock signal from the MG, for high quality recording and playback.

Make sure that the power switch of the unit is set to the “ ” position (off). Step 3 Powering Up the System To prevent an unwanted burst of noise from the speakers, power up the devices in the following order: peripheral devices (instruments, microphones, etc.) mixing console power amps (or powered speakers). Reverse this order when turning the power off. WARNING 2. Connect the socket of the included power cord to the [AC IN] jack on the rear panel. Be sure to turn the power on/off in the order given in Step 3 above every time you use the mixer. Failure to do so may result in loud noise bursts that can damage your equipment, your ears, or both. 3. Plug the power cord into a power outlet. NOTICE Step 2 Making Connections If you are using condenser microphones that require phantom power, turn the mixer’s [PHANTOM +48V] switch on before turning on the power to the power amps or powered speakers. See page 17 for details. Also, read the details about the [PHANTOM +48V] switch on page 17 before turning the switch on. 1. Turn all the faders and [GAIN] knobs completely down. 2. Connect the microphones, instruments, and/or speakers you intend to use. For details on making connections, see “Setup Examples” (pages 12 – 13), “Front Panel” and “Rear Panel” (pages 14 – 15).

Use the [FX RTN] fader to adjust the overall effect depth of the selected effect. You can use the [PARAMETER] knob (page 23) to adjust effect parameters such as reverb time and delay time. For details about the parameters of each effect that can be adjusted with the [PARAMETER] knob, see page 33. Using Reverb and Delay Your mixes can be further enhanced by using the built-in ambience effects such as reverb or delay. Reverb and Delay Time The optimum reverb time for a piece of music will depend on the music’s tempo and density, but as a general rule longer reverb times are good for ballads, while shorter reverb times are more suited to up-tempo tunes. Delay times can be adjusted to create a wide variety of repeating rhythmic effects. When adding a delay to a vocal, for example, try setting the delay time to dotted eighth notes ( e. ) corresponding to the tune’s tempo. Reverb Level While working for many hours on a mix, your sense of hearing will start to dull slightly. This can lead to the perception that tracks with excess processing sound like the perfect mix. To avoid falling into this trap, start with reverb level all the way down, then gradually bring the reverb into the mix until you can just hear the difference. Any more than this normally becomes a special effect or, worse yet, makes the sound muddy and indistinct. In general, you don’t want reverb to dominate the mix, so you should apply it judiciously.

Red 34 MG20XU/MG20/MG16XU/MG16/MG12XU/MG12 Owner’s Manual Appendix Mounting Procedures Rack Mounting The MG12XU/MG12 require at least 10 U* of rack space. To take into account the cable connections, we recommend to ensure 11 U* of rack space. The MG20XU/MG20/MG16XU/MG16 require at least 12 U* of rack space. To take into account the cable connections, we recommend to ensure 14 U* of rack space. (The illustration shows the MG12XU.) 1. Use a screwdriver to loosen the screws on the sides of the mixer (six total). * 10 U is approximately 445 mm, 11 U is approximately 489 mm, 12 U is approximately 533 mm, and 14 U is approximately 623 mm. Precautions for Rack Mounting This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. If you install this unit along with other devices in a poorly ventilated rack, the ambient temperature inside the rack may rise, resulting in inefficient performance. Be sure to rack-mount in the following conditions so the unit does not overheat. • When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave more than 1 U of space between the MG and other equipment. Also, either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup. 2. Use the screws removed in Step 1 to install the rack-mount kit (included with MG20XU/MG20/ MG16XU/MG16, optional RK-MG12 for the MG12XU/MG12 sold separately) on the mixer. NOTICE Be sure to use the screws removed in Step 1. Using other screws can cause damage. • To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If the rear of the rack cannot be left open, install a commercially available fan or similar ventilating option to secure sufficient airflow. If you’ve installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and/or fan unit manual for details.
