ContentsMain Features
Sophisticated analog circuits D-PRE (Discrete
Class-A MIC preamp)
Mono input channels are equipped with Class-A discrete microphone
preamplifiers.
The head amplifier features an inverted Darlington circuit* used in
high-end audio devices, and reproduces low frequencies with excep-
tionally musical characteristics as well as sustained high frequencies.
Independent toggle switching of +48V phantom power and 26dB (pad)
on each channel.
* Inverted Darlington circuit: An amplifying method for eliminating the
nonlinear characteristics of the amplifier element and suppress-
ing the distortion.
The circuit features highly musical phase characteristics.
EQ (equalizer)
The shelving EQ (low/high) on the mono input channels features
Xpressive EQ, which effectively models analog EQ utilizing Yamaha’s
famed VCM (Virtual Circuitry Modeling) technology. We analyzed
vintage EQ analog circuits and redesigned the technology specifically
for the MGP to create an EQ with exceptionally musical characteris-
tics. Furthermore, the cutoff frequency can also be adjusted, enhancing
use of the EQ in sound reinforcement applications, and extending the
sonic control range of the mixer.
Digital effects — REV-X and SPX (pages 21, 28)
Two powerful digital effect blocks are built into the mixer: REV-X (8
types) and SPX (16 types). REV-X gives you a high-density, richly
reverberant sound ambience, with smooth attenuation, spread and
depth that work together to enhance the original sound. The versatile
SPX block features a variety of effect applications, such as reverb,
delay, and modulation effects, along with complex combinations of
multiple effects.
Convenient, practical func-
tions for events – Ducker,
Leveler, and Stereo Image
(pages 14, 18, 19)
The mixer features three exceptionally
convenient features for the stereo input
channels: Ducker, Leveler and Stereo
Image. The Ducker function automatically lowers the level of back-
ground music to accommodate the voice of an announcer coming in on
another channel. The Leveler function automatically maintains a con-
sistent sound volume, even when using sound sources that have differ-
ent mastering levels, such as on an iPod/iPhone filled with a variety of
sources classified according to different genres and ages. Stereo Image
narrows the pan balance of the stereo sound source, and changes stereo
signals to mono. This is useful in restaurants and other spaces where
the left and right speakers are distantly positioned, or when you input
accompaniment sound to the left channel and vocal sound to the right
and want a more natural stereo image.
USB port for playing and charging your iPod/iPhone
(page 20)
The mixer has a built-in USB port (at top) for connection to an iPod/
iPhone. Digital audio output from the iPod/iPhone can be directly input
to the unit, and the iPod/iPhone can be charged while connected.

Making the Most of Your Mixer
Balanced Cables and Unbal-
anced Cables
Two types of cables can be used to connect microphones, elec-
tronic instruments, and other audio sources to the mixer’s inputs,
as well as to connect the mixer’s outputs to a power amplifier or
related gear: balanced or unbalanced.
Balanced cables are highly resistant to noise, and are the best
choice for low-level signals such as the output from microphones,
as well as for long cable runs. Unbalanced cables are generally
used for short runs from line-level sources such as synthesizers.
Cable Guidelines
Connector Types
XLR connectors
This 3-pin connector is resistant to externally induced noise, and
is used primarily 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 profes-
sional audio gear.
Phone jacks
Phone jacks are available in mono and stereo versions. Stereo
types are also known as “TRS” connectors (Tip-Ring-Sleeve),
and are used for stereo headphone jacks, insert jacks, and also to
carry balanced signals in many cases. Unbalanced types are used
for mono signals -guitar cables are a common example.
RCA Pin Connectors
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.
Microphones Balanced is best.
Short line-level cables
Unbalanced cable is fine in a rela-
tively noise-free environment.
Long line-level cables Balanced is best.

Making the Most of Your Mixer
Level Adjustment for Optimum
Mix
Equalizer Tips
The best advice that can be given regarding equalization while
recording is simply to use as little equalization as possible. If you
want a little more presence you can turn the HIGH end up a bit.
Or you can boost the bass a little if you feel the low end is lack-
ing. During recording it’s better to use EQ sparingly for compen-
sation only.
Cut for a Cleaner Mix
For example: pianos have a lot of energy in the mid and low fre-
quency ranges that you don’t really perceive as musical sound,
but which can interfere with the clarity of other instruments in
these ranges.
You can basically turn the low EQ on piano channels all the way
down without changing the way they sound in the mix. You’ll
hear the difference, however, in the way the mix sounds more
“spacious,” and instruments in the lower ranges will have better
definition.
Naturally you won’t want to do this if the piano is playing solo.
The reverse applies to kick drums and bass guitars: you can often
roll off the high end to create more space in the mix without com-
promising the character of the instruments. You’ll have to use
your ears, though, because each instrument is different and some-
times you’ll want the “snap” of a bass guitar, for example, to
come through.
The fundamental and harmonic frequency ranges
of some musical instruments.
Comp settings
One form of compression known as “limiting” can, when prop-
erly used, produce a smooth, unified sound with no excessive
peaks or distortion. A common example of the use of compres-
sion is to “tame” a vocal that has a wide dynamic range in order
to tighten up the mix. Compression can also be applied to guitar
tracks to add extra sustain. Too much compression can be a cause
of feedback, however, so use it sparingly.
Use the High-pass Filter for Microphone
Input
As the name implies, a “high-pass filter” allows only signals
above a certain frequency to pass. Conversely, signals below that
“cutoff frequency” are attenuated. When an MGP high-pass filter
is turned on, signals below 100Hz are attenuated.
This can be useful for minimizing low-frequency breath noise
from a vocalist, as well as handling noise, or rumble transmitted
via the microphone stand. It is generally a good idea to turn the
high-pass filter on for microphone channels.
Start with the Featured Part
You can start working on a mix from almost any part, but it makes
the most sense to start with the main instrument or vocal. Set up
an initial level for the main part, and then build the rest of the mix
around it.
For example, if you’re mixing a piano trio with a vocalist, begin
by setting the level of the vocal track at around the nominal level,
and then gradually add the other instruments. Your choices will
also be influenced by the type of music you are working on. If the
song is a ballad you might want to add the piano to the mix after
the vocal, and then add the bass and drums. If it’s a more rhythmi-
cally oriented piece you could add the bass and drums first, and
then the piano. Whatever best serves the music is right.

Rack Mounting
The unit requires at least 11U* of rack space. To take into
account the cable connections, we recommend to ensure at least
13U* of rack space.
* 11U corresponds to about 489mm and 13U is about 578mm.
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 1U of space between the MGP and other equipment.
Also either leave the open spaces uncovered or install appropri-
ate 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 commer-
cially available fan or similar ventilating option to secure suffi-
cient airflow. If you’ve installed a fan kit, there may be cases in
which closing the rear of the rack will produce a greater cool-
ing effect. Refer to the rack and/or fan unit manual for details.
Mounting the MGP16X/MGP12X
1. Two metal rack-mount brackets are screwed
onto the unit. Use a screwdriver to remove
these brackets.
2. Turn the brackets over, and fasten them into
place again using the same screws.
Fasten them to the mixer in order (as shown): q center,
w front, and e back.
CAUTION
Be sure to use the same screws that were removed in step
1. Using other screws can cause damage.

Similarly fasten the other side as well.
CAUTION
Be sure to use the included screws with the MGP12X.
Using other screws can cause damage.
5. Mount the unit into the rack, and fasten it into
place.
Security Cover Mounting
In order to prevent the control knobs of the front panel from being
operated inadvertently, you can attach a protective cover using
four screw holes on the unit. (Size: M3; horizontal spacing:
410mm for MGP16X and 311mm for MGP12X; vertical spacing:
208.5mm.) Yamaha does not sell such a cover; however, you can
easily make one yourself and attach it to the front cover.
When mounting a cover make sure that the screws used do not go
deeper than 12 millimeters into the front panel. Also, to ensure
that the cover does not come in contact with the panel controls,
leave a space of about 20–25 millimeters between the front panel
and the cover.

Quick Start Guide
We’ll begin this guide by connecting a pair of speakers
and generating some stereo output. Note that the oper-
ations 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] connector.
3. Plug the power cord into a power outlet.
Step 2 Connections
1. Turn all the faders and gain controls com-
pletely down.
2. Connect the microphones and/or instruments
you intend to use.
For details on making connections, refer to the “Setup Exam-
ples” on pages 8, 9.
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 (instrument, micro-
phone, iPod) MGP mixer power amps (or
powered speakers).
Reverse this order when turning the power off.
CAUTION
• If you are using condenser microphones that require phan-
tom power, turn the mixer’s +48V switch on before turning
on the power to the power amps or powered speakers. See
page 18 for details.
• Be sure to turn the power on/off in the order given in Step 3
above every time you use the device. Failure to do so may
result in loud noise bursts that can damage your equipment,
your ears, or both.

Although electric guitars and basses can be connected directly
to the mixer’s inputs, the sound is likely to be thin and possibly
noisy. For best results with these types of instruments use a DI
box (direct box) or amp simulator between the instrument and
the mixer.

Step 4 Getting Sound to the
Speakers
1. Adjust the channel GAIN controls so that the
corresponding peak indicators flash briefly on
the highest peak levels.
NOTE
To use the level meter to get an accurate reading of the incom-
ing signal level, turn the channel PFL switch on. Adjust the
GAIN controls so that level meter indication occasionally rises
above the “<” (0) level.
Note that the PHONES jack outputs the pre-fader signal from
all channels for which the PFL switch is ON, so that those sig-
nals can be monitored via the headphones.
2. Turn on the ON and ST switches for each chan-
nel you are using.
3. Make sure that all PFL and AFL switches are
set to off ( ).
4. Turn on ( ) the ON switch for the STEREO
master.
5. Raise the STEREO master fader to the “0”
position.
6. Set the channel faders to create the desired
initial balance.
7. Adjust the overall volume of the STEREO mas-
ter fader.
The overall headphone level is adjusted by the MONITOR/
PHONES control.
NOTE
If the PEAK indicator lights frequently, slightly lower the chan-
nel faders to avoid distortion.
Step 5 Using the Built-in Digital
Effects
1. Turn the [PROGRAM] knob to select the
desired effect, and then press the knob to
enable it.
For details about available effects, see the Digital Effect Pro-
gram List on page 28.
2. Turn on ( ) the FX1/FX2 ON button.
The button lights up when it is turned on.
3. Set the FX1/FX2 RTN fader to the “0” position.
4. Use the channel FX1/FX2 controls to adjust the
effect depth for each channel.
5. Use the FX1/FX2 RTN fader to adjust the over-
all effect depth.
You can use the PARAMETER control 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 control, see page 28.

Step 6 <Application>
Using the Ducker function
1. Connect a music player or device for playing
background music.
Connect the device to CH13/14 or CH15/16 on the MGP16X,
and to CH9/10 or CH11/12 on the MGP12X.
To connect an iPod/iPhone, use the USB terminal of the
MGP, and then set to the TO CH15/16 (TO CH11/12) switch
to USB ( ).
2. Turn on ( ) the DUCKER switch for each
channel you are using, and then adjust the
channel’s input to an appropriate level.
3. Connect the microphone to the SOURCE chan-
nel (MGP16X: CH8, MGP12X: CH4).
4. Adjust the input of the microphone to an
appropriate level.
5. Turn on ( ) the ON switch of the SOURCE
channel, and then raise the channel fader to
around “0” (nominal).
6. Play the background music, and listen to con-
firm that the sound volume automatically turns
down when you speak into the microphone.
NOTE
• The volume on the SOURCE channel is detected after fader
adjustment.
It is affected by the setting of ON switch and/or the channel
fader.
• If you want to make custom changes to the automatic sound
attenuation, refer to “About the Detailed Setting Mode” on
page 21.
Built-in digital effects
Your mixes can be further refined by adding ambience effects
such as reverb or delay.
The MGP’s internal effects can be used to add reverb or delay
to individual channels in the same way as external effects pro-
cessors.
Reverb and Delay Time
Small adjustments to the reverb/delay time can actually have a
significant effect on the sound. 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
“grooves.” When adding delay to a vocal, for example, try set-
ting the delay time to dotted eighth notes (e.) corresponding to
the tune’s tempo.
Reverb Tone
Different reverb programs will have different “reverb tone” due
to differences in the reverb time of the high or low frequencies.
Too much reverb, particularly in the high frequencies, can
result in unnatural sound and interfere with the high frequen-
cies in other parts of the mix. It’s always a good idea to choose
a reverb program that gives you the depth you want without
detracting from the clarity of the mix.
Reverb Level
It’s amazing how quickly your ears can lose perspective and
fool you into believing that a totally washed-out mix sounds
perfectly fine. 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.”
You don’t want reverb to dominate the mix unless you are try-
ing to create the effect of a band in a cave-which is a perfectly
legitimate creative goal if that’s the sort of thing you’re aiming
for.

Where Your Signal Goes Once It’s Inside the Box
The purpose of configuring an audio system around a mixer is to collect signals from all channels and mix their levels and other settings
to achieve a good balance. The following simplified mixer block diagram shows how the input signal flows once it’s inside the mixer. For
an overall block diagram of the MGP, see page 33.
Input channel
q Head amp
The very first stage in any mixer, and usually the only stage
with significant “gain” or “amplification.” The head amp has
a “gain” control that adjusts the mixer’s input sensitivity to
match the level of the source. Small signals (e.g. mics) are
amplified, and large signals are attenuated.
w Equalizer
An equalizer boosts (amplifies) or cuts (attenuates) certain
frequency ranges to shape the tone. It can be used to modify
the tone to suit the acoustic characteristics of a room, to make
creative sounds, or for many other purposes. An equalizer
could be a high pass filter that cuts the sound below a speci-
fied frequency.
e PEAK indicator
When the level of an input signal exceeds the level that can be
handled by the mixer’s head amp or equalizer, distortion and
noise will result. The PEAK indicators are used to visually
check the signal level to ensure no overload occurs.
If the PEAK indicator lights continuously, make sure that sig-
nals are not amplified too much by the equalizer, and if
needed, adjust the GAIN control of the head amp to reduce
the level.
It is important to know the mixer stage for which the PEAK
indicators are indicating signal levels. The PEAK indicator of
this unit detects the signal after the head amp and EQ stage.
r Channel fader
A channel fader enables you to adjust the level of the corre-
sponding input channel signal that is going to be routed to the
buses (excluding a pre-fader signal). It is the most often used
control during performance.
Master section
t Bus (Summing Amplifier)
This is where the actual “mixing” takes place. Signals from
all of the mixer’s input channels are “summed” (mixed)
together here.
The signals flow in each channel from top to down after being
adjusted by the level control, and then these signals are
summed (mixed) from left to right. Finally, the overall level is
adjusted by the master control located at far right.
The operation of summing from left to right is the role of the
bus (summing amplifier).
y Master control and level meter
The master controls, specifically, the STEREO fader and
GROUP faders, are the means used to adjust the level of all
signals from all of the mixer’s input channels. The level meter
LED shows the level of the signal flowing to the STEREO
bus.

q +48V switch and indicator
This switch toggles phantom power on and off. When this
switch is turned on ( ), the mixer supplies DC +48V
power to pins 2 and 3 of all XLR input jacks. Turn this switch
on when using one or more phantom-powered condenser
microphones. The indicator lights when it is turned on.
CAUTION
• Be sure to leave this switch off ( ) if you do not need
phantom power. Humming or damage may result if you
connect to an unbalanced device or to an ungrounded
transformer while this switch is on.
• When turning the switch on, make sure that only a con-
denser microphone is connected to the XLR input jacks.
Devices other than condenser microphones may be
damaged if connected to the phantom power supply.
This precaution does not apply to balanced dynamic
microphones, however, as these will not be affected by
phantom power.
• To prevent damage to speakers, be sure to turn off power
amplifiers (or powered speakers) before turning this
switch on or off. It’s also a good idea to turn the mixers
output controls - the STEREO master and GROUP (1-2,
3-4) faders - all the way down when turning phantom
power on. Neglect of these precautions may result in
large noise bursts that may damage your equipment,
your ears, or both.
w 26dB (PAD) switch
When this switch is turned on ( ), the input signal from
the MIC/LINE jack of the mono channel is attenuated by
26dB.
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.
e (High Pass Filter) switch
Turning this switch on ( ) will apply a high-pass filter that
attenuates frequencies below 100Hz in the signal by a slope
of 12dB/octave.
r DUCKER switch
When this switch is turned on ( ), the volume of the stereo
channels is automatically lowered when a signal exceeding a
certain level is input to the SOURCE channel (MGP16X:
CH8, MGP12X: CH4). You can use this switch, for example,
when you want to have the volume of background music
automatically lowered when making an announcement on the
microphone. For effective use of this switch, see Step 6 on
page 14. The switch lights when it is turned on.
NOTE
You can adjust the attenuation of the Ducker function in the
detailed setting mode (see column on page 21).

t LEVELER switch and indicator
When playing music from an iPod/iPhone or other audio
players, the actual sound output level may differ for each
song depending on the assigned category. Turning this switch
on ( ) lets you have the volume adjusted automatically to
a certain level, preventing sudden jumps or dips in the level.
The indicator lights when it is turned on.
NOTE
If an audio player other than iPod/iPhone is connected to the
input jacks (LINE) on the rear panel, initially adjust the input
level according to the softest part (lowest level) of the song,
and then turn on the LEVELER switch. Adjust the input level so
that the level meter indication occasionally rises above the “<”
(0) level while the PFL switch is on.
y GAIN control
Adjusts the sensitivity of the input signal. Monaural channels
have a 26dB switch (w) that lets you change the range of this
control. The adjustable sensitivity range is as follows.
Mono channel
Stereo channel
-34dB to +10dB
u COMP control and indicator
Adjusts the amount of compression applied to the channel.
As the knob is turned to the right the compression ratio
increases while the output gain is automatically adjusted
accordingly. The result is smoother, more even dynamics
because louder signals are attenuated while the overall level
is boosted. The COMP indicator will light when the compres-
sor operates.
NOTE
Avoid setting the compression too high, as the higher average
output level that results may lead to feedback.
i STEREO IMAGE switch
This switch selects the output signal by switching the input
stereo signal to one of the following three signal types.
• MONO : Mono signal
• BLEND : Stereo signal in which left and right inputs
are mixed in a certain percentage for a more nat-
ural stereo image.
• STEREO : Stereo signal (original, as is)
o Equalizer (HIGH, MID, and LOW)
This three-band equalizer adjusts the channel’s high, mid, and
low frequency bands.
Setting the knob to the “t” position produces a flat response
in the corresponding band. Turning the knob to the right
boosts the corresponding frequency band, while turning to the
left attenuates the band. The upper knob sets the center fre-
quency for the mid range, while the lower knob sets the
amount of attenuation or boost (counterclockwise/clockwise)
for the range. For the CH9/10 and CH11/12 (on the
MGP16X), and CH5/6 and CH7/8 (on the MGP12X), the
attenuation/boost can only be set at a fixed 2.5kHz center fre-
quency.
The following table shows the EQ type, frequency, and cut/
boost range for each of the three bands.
* The MID frequency can be adjusted from 250Hz to 5kHz.
The MID frequency is 2.5kHz when the MID frequency
control is set at the center position.
!0 AUX1 PRE, AUX2 controls
These knobs adjust the channel’s signal levels sent to AUX
buses 1 and 2. Each knob controls the signal sent to the corre-
sponding AUX bus. These knobs should generally be set
close to the “t” (nominal) position. The AUX1 control
adjusts the signal before the channel fader (pre-fader). The
signal adjusted by the AUX2 control is determined by the
PRE switch (!1).
!1 PRE switch
This switch selects whether the signal sent to the AUX 2 bus
is taken after the equalizer but before the channel fader (pre-
fader), or after the channel fader (post-fader). When the
switch is on ( ), the mixer sends the pre-fader signal to the
AUX2 bus, so that the AUX2 output is not affected by the
fader.
!2 FX1, FX2 controls
Adjusts the level of the signal (post-fader) sent from the chan-
nel into the FX bus. These knobs should generally be set
close to the “t” position.
NOTE
• To send the signal to the bus engage the ON switch (!4).
• On stereo channels, the LINE L (odd) and LINE R (even)
input signals are mixed before moving into the bus.

PAN/BAL control
BAL control
The PAN control knob determines the stereo positioning of
each mono channel signal in the GROUP 1-2, 3-4 buses or in
the stereo L and R buses. For example, rotating the knob
toward L moves the sound to the left (depending on the loca-
tion of the knob).
The BAL control knob sets the balance between left and right
stereo channels. For example, rotate the knob toward L to
increase the volume level of the left or Groups 1 and 3, and
decrease the level of the right or Groups 2 and 4.
!4 ON switch
Turn this switch on ( ) to send the respective channel’s
signal to the buses. The switch lights when on.

The LEDs indicate the input channel’s post-equalizer signal
level. The SIG indicator lights when a signal is being input
into the channel. The PEAK indicator lights when the input
signal level is 3dB below clipping.

These switches determine the bus(es) to which each channel’s
signal is sent. Press the switch in ( ) to output the signal to
the corresponding buses.
• 1-2, 3-4 switches: Assign the channel’s signal to the
GROUP1-2, 3-4 buses.

• INSERT: These jacks are located between the com-
pressor and equalizer of the corresponding input
channel. The INSERT jacks are ideal for connect-
ing devices such as graphic equalizers or noise
filters into the corresponding channels. These are
TRS (tip, ring, sleeve) phone jacks that carry both
the send and return signal (tip = send/out; ring =
return/in; sleeve = ground).
NOTE
Connection to an INSERT I/O jack requires a special insertion
cable as illustrated below. Use a separately-sold Yamaha inser-
tion cable (YIC025/050/070).
CAUTION
The signal output from the INSERT jacks is reverse-
phased. This should not be a problem when connecting to
an effect unit, but please be aware of the possibility of
phase conflict when connecting to other types of device.
A reversed-phased signal may result in degraded sound
quality or even complete sound cancellation.
• MIC/LINE: These are combo jacks that support both
XLR-type and TRS phone-type plugs, and are for
connection of both microphones and/or instru-
ments.
w Mono/Stereo inputs
• LINE: These are unbalanced phone-jack stereo line
inputs.
• MIC: These are balanced XLR-type microphone input
jacks. (1: Ground; 2: Hot; 3: Cold)
NOTE
On any given channel, you may use either an XLR or phone
jack, but not both.
e Stereo input
• LINE: These are stereo input jacks that connect line-
level instruments, such as a synthesizer. These
are unbalanced input jacks. Two jack types are
provided: phone type and RCA pin type.
NOTE
On any given channel, you may use either a phone or RCA
jack, but not both.

Master I/O connectors section
r 2TR IN
These RCA pin jacks can be used to input a stereo sound
source. Use these jacks when you want to connect a CD
player, and output the signal to the monitor or the STEREO
L/R bus.
NOTE
You can adjust the signal level using the 2TR IN control in the
Master Control block.
t REC OUT
These RCA pin jacks can be connected to an external
recorder such as an MD recorder in order to record the same
signal that is being output via the STEREO OUT jacks.
NOTE
The mixer’s STEREO master fader has no affect on the signal
output via these jacks. Be sure to make appropriate level
adjustments at the recording device.
y MONITOR OUT
Connect these impedance-balanced* TRS phone jacks to
your monitor system. These jacks output the signal before or
after the faders for the various buses. The PFL and AFL indi-
cators in each section indicate which signal is being output.
NOTE
The PFL switch has priority when both the PFL switch and AFL
switch are on. To monitor the post-fader signal, make sure to
turn off all PFL switches.
u RETURN
These are unbalanced phone-jack type line input jacks. The
signal received by these jacks is sent to the STEREO L/R
buses and the AUX1 and AUX2 buses. The mixed signal of L
(MONO) and R is sent to the AUX1 and AUX2 buses.
These jacks are typically used to receive the signal returned
from an external effect device (reverb, delay, etc.).
NOTE
• These jacks can also be used as an auxiliary stereo input.
• If you connect to the L (MONO) jack only, the mixer will rec-
ognize the signal as monaural and will send the identical sig-
nal to both the L and R jacks.
i GROUP OUT
These impedance-balanced* TRS phone jacks output the
GROUP 1-2, 3-4 signals. Use these jacks to connect to the
inputs of a multi-track recorder, external mixer, or another
similar device.
o SEND
You use these jacks, for example, to connect to an effect
device or monitor system.
• AUX1, AUX2: These are balanced XLR-3-32 type out-
put jacks (1: Ground; 2: Hot; 3: Cold).
• FX1, FX2: These are impedance balanced* phone-
jack type output jacks. These jacks output the
signals from the FX1 and FX2 buses, respec-
tively.
!0 STEREO OUT
These are XLR type and TRS phone type balanced output
jacks that output the mixed stereo signal. The signal level is
adjusted by the STEREO master fader before it is output. You
can use these jacks, for example, to connect to the power
amplifier driving your main speakers.
Power section
!1 POWER switch
Turns power to the unit ON or OFF. Press the switch to the
“ ” position to turn on the power. Press the switch to the
“ ” position to turn off the power.
CAUTION
Rapidly turning the unit ON and OFF in succession can
cause it to malfunction. After turning the unit OFF, wait for
about 6 seconds before turning it ON again.
!2 AC IN connector
Connect the included power cord here. First, connect the
power cord to the MGP, and then plug it into an AC outlet.
* Impedance balanced
Since the hot and cold terminals of impedance balanced
output jacks have the same impedance, these output jacks
are less affected by induced noise.

Please read this manual thoroughly to make the best use of the mixing console for the longest possible period of time. After reading this manual, please keep it available for future reference. Explanation of Graphical Symbols Explication des symboles CAUT I ON The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. RISK OF ELECTRIC SHOCK DO NOT OPEN L’éclair avec une flèche à l’intérieur d’un triangle équilatéral est destiné à attirer l’attention de l’utilisateur sur la présence d’une « tension dangereuse » non isolée à l’intérieur de l’appareil, pouvant être suffisamment élevée pour constituer un risque d’électrocution. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. Le point d’exclamation à l’intérieur d’un triangle équilatéral est destiné à attirer l’attention de l’utilisateur sur la présence d’instructions importantes sur l’emploi ou la maintenance (réparation) de l’appareil dans la documentation fournie. The above warning is located on the rear of the unit. L’avertissement ci-dessus est situé sur le arrière de l’appareil. IMPORTANT SAFETY INSTRUCTIONS PRÉCAUTIONS CONCERNANT LA SÉCURITÉ 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Read these instructions. Keep these instructions. Heed all warnings. Follow all instructions. Do not use this apparatus near water. Clean only with dry cloth. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

(UL60065_03) 2 MGP16X/MGP12X Owner’s Manual Main Features Contents Sophisticated analog circuits D-PRE (Discrete Class-A MIC preamp) Main Features ................................ 3 Mono input channels are equipped with Class-A discrete microphone preamplifiers. The head amplifier features an inverted Darlington circuit* used in high-end audio devices, and reproduces low frequencies with exceptionally musical characteristics as well as sustained high frequencies. Independent toggle switching of +48V phantom power and 26dB (pad) on each channel. PRECAUTIONS.................................4 Making the Most of Your Mixer............ 6 * Inverted Darlington circuit: An amplifying method for eliminating the nonlinear characteristics of the amplifier element and suppressing the distortion. The circuit features highly musical phase characteristics. Setup ........................................... 8 EQ (equalizer) The shelving EQ (low/high) on the mono input channels features Xpressive EQ, which effectively models analog EQ utilizing Yamaha’s famed VCM (Virtual Circuitry Modeling) technology. We analyzed vintage EQ analog circuits and redesigned the technology specifically for the MGP to create an EQ with exceptionally musical characteristics. Furthermore, the cutoff frequency can also be adjusted, enhancing use of the EQ in sound reinforcement applications, and extending the sonic control range of the mixer. Digital effects — REV-X and SPX (pages 21, 28) Two powerful digital effect blocks are built into the mixer: REV-X (8 types) and SPX (16 types). REV-X gives you a high-density, richly reverberant sound ambience, with smooth attenuation, spread and depth that work together to enhance the original sound. The versatile SPX block features a variety of effect applications, such as reverb, delay, and modulation effects, along with complex combinations of multiple effects. Convenient, practical functions for events – Ducker, Leveler, and Stereo Image (pages 14, 18, 19) The mixer features three exceptionally convenient features for the stereo input channels: Ducker, Leveler and Stereo Image. The Ducker function automatically lowers the level of background music to accommodate the voice of an announcer coming in on another channel. The Leveler function automatically maintains a consistent sound volume, even when using sound sources that have different mastering levels, such as on an iPod/iPhone filled with a variety of sources classified according to different genres and ages. Stereo Image narrows the pan balance of the stereo sound source, and changes stereo signals to mono. This is useful in restaurants and other spaces where the left and right speakers are distantly positioned, or when you input accompaniment sound to the left channel and vocal sound to the right and want a more natural stereo image.

PA_en_1 2/2 MGP16X/MGP12X Owner’s Manual 5 Making the Most of Your Mixer Balanced Cables and Unbalanced Cables Two types of cables can be used to connect microphones, electronic instruments, and other audio sources to the mixer’s inputs, as well as to connect the mixer’s outputs to a power amplifier or related gear: balanced or unbalanced. Balanced cables are highly resistant to noise, and are the best choice for low-level signals such as the output from microphones, as well as for long cable runs. Unbalanced cables are generally used for short runs from line-level sources such as synthesizers. Connector Types XLR connectors This 3-pin connector is resistant to externally induced noise, and is used primarily 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. Cable Guidelines Microphones Balanced is best. Short line-level cables Unbalanced cable is fine in a relatively noise-free environment. Long line-level cables Balanced is best. Male Female Phone jacks Phone jacks are available in mono and stereo versions. Stereo types are also known as “TRS” connectors (Tip-Ring-Sleeve), and are used for stereo headphone jacks, insert jacks, and also to carry balanced signals in many cases. Unbalanced types are used for mono signals -guitar cables are a common example. Stereo/TRS phone plug Mono phone plug RCA Pin Connectors 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. White Red 6 MGP16X/MGP12X Owner’s Manual Making the Most of Your Mixer Level Adjustment for Optimum Mix Equalizer Tips The best advice that can be given regarding equalization while recording is simply to use as little equalization as possible. If you want a little more presence you can turn the HIGH end up a bit. Or you can boost the bass a little if you feel the low end is lacking. During recording it’s better to use EQ sparingly for compensation only. Comp settings One form of compression known as “limiting” can, when properly used, produce a smooth, unified sound with no excessive peaks or distortion. A common example of the use of compression is to “tame” a vocal that has a wide dynamic range in order to tighten up the mix. Compression can also be applied to guitar tracks to add extra sustain. Too much compression can be a cause of feedback, however, so use it sparingly. Output 0 (Min) 10 (Max) Cut for a Cleaner Mix For example: pianos have a lot of energy in the mid and low frequency ranges that you don’t really perceive as musical sound, but which can interfere with the clarity of other instruments in these ranges. You can basically turn the low EQ on piano channels all the way down without changing the way they sound in the mix. You’ll hear the difference, however, in the way the mix sounds more “spacious,” and instruments in the lower ranges will have better definition. Naturally you won’t want to do this if the piano is playing solo. The reverse applies to kick drums and bass guitars: you can often roll off the high end to create more space in the mix without compromising the character of the instruments. You’ll have to use your ears, though, because each instrument is different and sometimes you’ll want the “snap” of a bass guitar, for example, to come through. The fundamental and harmonic of some musical instruments. frequency ranges Cymbal Input Use the High-pass Filter for Microphone Input As the name implies, a “high-pass filter” allows only signals above a certain frequency to pass. Conversely, signals below that “cutoff frequency” are attenuated. When an MGP high-pass filter is turned on, signals below 100Hz are attenuated. This can be useful for minimizing low-frequency breath noise from a vocalist, as well as handling noise, or rumble transmitted via the microphone stand. It is generally a good idea to turn the high-pass filter on for microphone channels. Piano Start with the Featured Part Bass drum Snare drum Bass guitar Guitar Trombone Trumpet 20 50 100 200 500 1k 2k 5k 10k 20k (Hz) Fundamental: The frequency that determines the basic musical pitch. Harmonics: Multiples of the fundamental frequency that play a role in determining the timbre of the instrument. You can start working on a mix from almost any part, but it makes the most sense to start with the main instrument or vocal. Set up an initial level for the main part, and then build the rest of the mix around it. For example, if you’re mixing a piano trio with a vocalist, begin by setting the level of the vocal track at around the nominal level, and then gradually add the other instruments. Your choices will also be influenced by the type of music you are working on. If the song is a ballad you might want to add the piano to the mix after the vocal, and then add the bass and drums. If it’s a more rhythmically oriented piece you could add the bass and drums first, and then the piano. Whatever best serves the music is right. MGP16X/MGP12X Owner’s Manual 7 Setup Setup Examples 1.

To take into account the cable connections, we recommend to ensure at least 13U* of rack space. Mounting the MGP16X/MGP12X 1. Two metal rack-mount brackets are screwed onto the unit. Use a screwdriver to remove these brackets. * 11U corresponds to about 489mm and 13U is about 578mm. 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 1U of space between the MGP 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. 2.

In order to prevent the control knobs of the front panel from being operated inadvertently, you can attach a protective cover using four screw holes on the unit. (Size: M3; horizontal spacing: 410mm for MGP16X and 311mm for MGP12X; vertical spacing: 208.5mm.) Yamaha does not sell such a cover; however, you can easily make one yourself and attach it to the front cover. When mounting a cover make sure that the screws used do not go deeper than 12 millimeters into the front panel. Also, to ensure that the cover does not come in contact with the panel controls, leave a space of about 20–25 millimeters between the front panel and the cover. 4.

Note that the operations and procedures will vary somewhat according to the input devices you are using. Step 1 Preparing the Power Supply 1. Make sure that the power switch of the unit is set to the “ ” position (off). 2. Connect the microphones and/or instruments you intend to use. For details on making connections, refer to the “Setup Examples” on pages 8, 9. Front Panel Rear Panel When using a condenser microphone, set the +48V phantom switch to ON (page 18). 2. Connect the socket of the included power cord to the [AC IN] connector. 3. Plug the power cord into a power outlet. Step 2 Connections 1. Turn all the faders and gain controls completely down. GAIN controls Power switch (rear panel) DI Although electric guitars and basses can be connected directly to the mixer’s inputs, the sound is likely to be thin and possibly noisy. For best results with these types of instruments use a DI box (direct box) or amp simulator between the instrument and the mixer. 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 (instrument, microphone, iPod) MGP mixer power amps (or powered speakers). Reverse this order when turning the power off. CAUTION • If you are using condenser microphones that require phantom power, turn the mixer’s +48V switch on before turning on the power to the power amps or powered speakers. See page 18 for details. Faders • Be sure to turn the power on/off in the order given in Step 3 above every time you use the device. Failure to do so may result in loud noise bursts that can damage your equipment, your ears, or both. 12 MGP16X/MGP12X Owner’s Manual Quick Start Guide Step 4 Getting Sound to the Speakers Step 5 Using the Built-in Digital Effects 1. 1. Adjust the channel GAIN controls so that the corresponding peak indicators flash briefly on the highest peak levels. NOTE To use the level meter to get an accurate reading of the incoming signal level, turn the channel PFL switch on. Adjust the GAIN controls so that level meter indication occasionally rises above the “<” (0) level. Note that the PHONES jack outputs the pre-fader signal from all channels for which the PFL switch is ON, so that those signals can be monitored via the headphones. 2. Turn on the ON and ST switches for each channel you are using. 3. Make sure that all PFL and AFL switches are set to off ( 4. Turn on ( ). Turn the [PROGRAM] knob to select the desired effect, and then press the knob to enable it. For details about available effects, see the Digital Effect Program List on page 28. 2. Turn on ( ) the FX1/FX2 ON button. The button lights up when it is turned on. 3. Set the FX1/FX2 RTN fader to the “0” position. 4.

The MGP’s internal effects can be used to add reverb or delay to individual channels in the same way as external effects processors. Reverb and Delay Time Small adjustments to the reverb/delay time can actually have a significant effect on the sound. 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 “grooves.” When adding delay to a vocal, for example, try setting the delay time to dotted eighth notes (e.) corresponding to the tune’s tempo. Reverb Tone Different reverb programs will have different “reverb tone” due to differences in the reverb time of the high or low frequencies. Too much reverb, particularly in the high frequencies, can result in unnatural sound and interfere with the high frequencies in other parts of the mix. It’s always a good idea to choose a reverb program that gives you the depth you want without detracting from the clarity of the mix. Reverb Level It’s amazing how quickly your ears can lose perspective and fool you into believing that a totally washed-out mix sounds perfectly fine. 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.” You don’t want reverb to dominate the mix unless you are trying to create the effect of a band in a cave-which is a perfectly legitimate creative goal if that’s the sort of thing you’re aiming for. Step 6 <Application> Using the Ducker function 1. Connect a music player or device for playing background music. Connect the device to CH13/14 or CH15/16 on the MGP16X, and to CH9/10 or CH11/12 on the MGP12X. To connect an iPod/iPhone, use the USB terminal of the MGP, and then set to the TO CH15/16 (TO CH11/12) switch to USB ( ). 2. Turn on ( ) the DUCKER switch for each channel you are using, and then adjust the channel’s input to an appropriate level. 3. Connect the microphone to the SOURCE channel (MGP16X: CH8, MGP12X: CH4). 4. Adjust the input of the microphone to an appropriate level. 5. Turn on ( ) the ON switch of the SOURCE channel, and then raise the channel fader to around “0” (nominal). 6. Play the background music, and listen to confirm that the sound volume automatically turns down when you speak into the microphone. NOTE • The volume on the SOURCE channel is detected after fader adjustment. It is affected by the setting of ON switch and/or the channel fader. • If you want to make custom changes to the automatic sound attenuation, refer to “About the Detailed Setting Mode” on page 21.

The following simplified mixer block diagram shows how the input signal flows once it’s inside the mixer. For an overall block diagram of the MGP, see page 33. Simplified Mixer Block Diagram Input channel Master section PEAK CH Fader INPUT HA EQ LED meter q Head amp w Equalizer e PEAK indicator GROUP Fader r Channel fader STEREO Fader CHs INPUT OUTPUT SUM t Bus y Master control and level meter Input channel Master section q Head amp t Bus (Summing Amplifier) The very first stage in any mixer, and usually the only stage with significant “gain” or “amplification.” The head amp has a “gain” control that adjusts the mixer’s input sensitivity to match the level of the source. Small signals (e.g. mics) are amplified, and large signals are attenuated. w Equalizer An equalizer boosts (amplifies) or cuts (attenuates) certain frequency ranges to shape the tone. It can be used to modify the tone to suit the acoustic characteristics of a room, to make creative sounds, or for many other purposes. An equalizer could be a high pass filter that cuts the sound below a specified frequency. e PEAK indicator When the level of an input signal exceeds the level that can be handled by the mixer’s head amp or equalizer, distortion and noise will result. The PEAK indicators are used to visually check the signal level to ensure no overload occurs. If the PEAK indicator lights continuously, make sure that signals are not amplified too much by the equalizer, and if needed, adjust the GAIN control of the head amp to reduce the level. It is important to know the mixer stage for which the PEAK indicators are indicating signal levels. The PEAK indicator of this unit detects the signal after the head amp and EQ stage. This is where the actual “mixing” takes place. Signals from all of the mixer’s input channels are “summed” (mixed) together here. The signals flow in each channel from top to down after being adjusted by the level control, and then these signals are summed (mixed) from left to right. Finally, the overall level is adjusted by the master control located at far right. The operation of summing from left to right is the role of the bus (summing amplifier). y Master control and level meter The master controls, specifically, the STEREO fader and GROUP faders, are the means used to adjust the level of all signals from all of the mixer’s input channels. The level meter LED shows the level of the signal flowing to the STEREO bus. r Channel fader A channel fader enables you to adjust the level of the corresponding input channel signal that is going to be routed to the buses (excluding a pre-fader signal). It is the most often used control during performance.

NOTE 18 MGP16X/MGP12X Owner’s Manual You can adjust the attenuation of the Ducker function in the detailed setting mode (see column on page 21). Controls and Connectors t LEVELER switch and indicator When playing music from an iPod/iPhone or other audio players, the actual sound output level may differ for each song depending on the assigned category. Turning this switch on ( ) lets you have the volume adjusted automatically to a certain level, preventing sudden jumps or dips in the level. The indicator lights when it is turned on. NOTE If an audio player other than iPod/iPhone is connected to the input jacks (LINE) on the rear panel, initially adjust the input level according to the softest part (lowest level) of the song, and then turn on the LEVELER switch. Adjust the input level so that the level meter indication occasionally rises above the “<” (0) level while the PFL switch is on. o Equalizer (HIGH, MID, and LOW) This three-band equalizer adjusts the channel’s high, mid, and low frequency bands. Setting the knob to the “t” position produces a flat response in the corresponding band. Turning the knob to the right boosts the corresponding frequency band, while turning to the left attenuates the band. The upper knob sets the center frequency for the mid range, while the lower knob sets the amount of attenuation or boost (counterclockwise/clockwise) for the range. For the CH9/10 and CH11/12 (on the MGP16X), and CH5/6 and CH7/8 (on the MGP12X), the attenuation/boost can only be set at a fixed 2.5kHz center frequency. The following table shows the EQ type, frequency, and cut/ boost range for each of the three bands. y GAIN control Adjusts the sensitivity of the input signal. Monaural channels have a 26dB switch (w) that lets you change the range of this control. The adjustable sensitivity range is as follows. Mono channel 26dB switch Range ON -34dB to +10dB OFF -60dB to -16dB Stereo channel -34dB to +10dB u COMP control and indicator Adjusts the amount of compression applied to the channel. As the knob is turned to the right the compression ratio increases while the output gain is automatically adjusted accordingly. The result is smoother, more even dynamics because louder signals are attenuated while the overall level is boosted. The COMP indicator will light when the compressor operates. NOTE Avoid setting the compression too high, as the higher average output level that results may lead to feedback. i STEREO IMAGE switch This switch selects the output signal by switching the input stereo signal to one of the following three signal types. • MONO : Mono signal • BLEND : Stereo signal in which left and right inputs are mixed in a certain percentage for a more natural stereo image. • STEREO : Stereo signal (original, as is) Band Type Frequency HIGH Shelving 8kHz MID Peaking 2.5kHz* LOW Shelving 125Hz Cut/Boost range ±15dB * The MID frequency can be adjusted from 250Hz to 5kHz. The MID frequency is 2.5kHz when the MID frequency control is set at the center position. !0 AUX1 PRE, AUX2 controls These knobs adjust the channel’s signal levels sent to AUX buses 1 and 2. Each knob controls the signal sent to the corresponding AUX bus. These knobs should generally be set close to the “t” (nominal) position. The AUX1 control adjusts the signal before the channel fader (pre-fader). The signal adjusted by the AUX2 control is determined by the PRE switch (!1). !1 PRE switch This switch selects whether the signal sent to the AUX 2 bus is taken after the equalizer but before the channel fader (prefader), or after the channel fader (post-fader). When the switch is on ( ), the mixer sends the pre-fader signal to the AUX2 bus, so that the AUX2 output is not affected by the fader. !2 FX1, FX2 controls Adjusts the level of the signal (post-fader) sent from the channel into the FX bus. These knobs should generally be set close to the “t” position. NOTE • To send the signal to the bus engage the ON switch (!4). • On stereo channels, the LINE L (odd) and LINE R (even) input signals are mixed before moving into the bus. MGP16X/MGP12X Owner’s Manual 19 Controls and Connectors !3 PAN control PAN/BAL control BAL control The PAN control knob determines the stereo positioning of each mono channel signal in the GROUP 1-2, 3-4 buses or in the stereo L and R buses. For example, rotating the knob toward L moves the sound to the left (depending on the location of the knob). The BAL control knob sets the balance between left and right stereo channels. For example, rotate the knob toward L to increase the volume level of the left or Groups 1 and 3, and decrease the level of the right or Groups 2 and 4. !4 ON switch Turn this switch on ( ) to send the respective channel’s signal to the buses. The switch lights when on. !5 Input Meter The LEDs indicate the input channel’s post-equalizer signal level. The SIG indicator lights when a signal is being input into the channel.
