Introduction
Thank you for purchasing the Yamaha MGP32X/MGP24X
mixing console.
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.
Main features
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 exceptionally 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 elimi-
nating the nonlinear characteristics of the amplifier element
and suppressing the distortion. The circuit features highly
musical phase characteristics.
Convenient, practical functions for events –
Ducker, Leveler, and Stereo Image
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. 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
Digital audio output from the iPod/iPhone can be directly input to
the unit, and the iPod/iPhone can be charged while connected.
X-pressive EQ
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.
USB device recorder
A USB device recorder is built into the mixer for recording mixed
audio to a USB device as an audio file, and for playing back
music saved in the USB device by assigning it to the desired
channel output or bus output. Supported file formats are MP3
(MPEG-1 Audio Layer-3) and WAV for recording and MP3,
WAV, and AAC for playback.
Stereo master – COMP and GEQ
The stereo master is equipped with a compressor (COMP) or
multiband compressor that adjusts the sound pressure of the output signal, and with a graphic equalizer (GEQ) that adjusts sound
quality such as feedback.
About the models
The MGP32X and MGP24X feature a different number of monaural input channels and COMP control knobs. The MGP32X has
24 monaural input channels and the MGP24X has 16. The
MGP32X is equipped with 16 COMP control knobs for channels
9-24 and the MGP24X with 8 COMP control knobs for channels
9-16.
Conventions in this manual
• Whenever there is a different number of channels or a different
channel number for the same function between the MGP32X
and the MGP24X, the number that applies only to the MGP24X
model is enclosed in curly brackets { }. For example, “CH1-24
{CH1-16}” means channels 1-24 for the MGP32X and channels 1-16 for the MGP24X.
* “CH” is an abbreviation for channel.
• Control knobs on the panel are called “knobs.” Some knobs
rotate from a minimum value to a maximum value, while others
rotate endlessly.
MGP Editor
MGP Editor is a free software application that gives you additional control of your MGP mixer’s DSP settings via your iPhone,
iPod touch, and iPad. See the following web site to download the
application.
http://www.yamahaproaudio.com/global/en/products/peripherals/applications/mgp_editor/
Digital effects — REV-X and SPX
Two powerful digital effect blocks are built into the mixer: REVX (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.

Turning this switch on ( ) attenuates the input signal from
the INPUT jack of the mono channel by 26dB. Turn this
switch off ( ) if you have connected a microphone or other
device with a low input level to the channel. Turn it on ( )
if you have connected a line-level device.
w +48V switch and indicator
Toggles phantom power on and off. When this switch is
turned on ( ), the mixer supplies DC +48V power to
INPUT A of XLR input jacks. Turn this switch on when
using one or more phantom-powered condenser microphones.
The indicator is on when the switch is on.
CAUTION
• Be sure to leave this switch off ( ) if you do not need
phantom power.
• When turning phantom power on ( ), follow the important precautions below, in order to prevent noise and
possible damage to the mixer and external devices.
• Turn this switch off when connecting a device that
does not support phantom power to INPUT A of XLR
input jacks
• Do not connect/disconnect a cable to/from channels 1-
24 {1-16} while this switch on.
• Turn the mixer’s output controls – STEREO master and
GROUP faders- all the way down when turning phantom power on/off.
e GAIN knob
Adjusts the sensitivity of the input signal. Monaural channels
have a 26dB switch (q) 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
NOTE
The stereo channel is fixed to a range of -34dB to +10dB.
r (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.
t
COMP knobs and indicator (Channel 9-24 {9-16})
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 comes on when the compressor operates.
NOTE
Avoid setting the compression too high, as the higher average
output level that results may lead to feedback.

device will be input to CH29/30 {21/22}, while the signal
from an iPod/iPhone will be input to CH31/32 {23/24}.
NOTE
The GAIN knobs do not affect the volume of your iPod/iPhone.
To adjust the pre-channel-fader signal volume, refer to page

!0 STEREO IMAGE switch
Selects the type of output signal for the input stereo signal.
• MONO : Mono signal
• BLEND : Stereo signal in which left and right inputs
are mixed at a certain percentage for a more natural stereo image, and in which the pan is controlled.
• STEREO : Stereo signal (original, as is)
!1 Equalizer knobs (HIGH, MID, and LOW)
This three-band equalizer changes the tone of the high, mid,
and low frequency bands. Turning the knob to the right boosts
the corresponding frequency band, while turning to the left
attenuates the band. Setting the knob to the “t” position produces a flat response in the corresponding 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 CH25/26 and
CH27/28 {CH17/18 and CH19/20}, 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.

!2 AUX knobs (1-4)
These knobs adjust the channel’s signal levels into AUX
buses 1 to 4. Each knob controls the signal into the corresponding AUX bus. On stereo channels, the LINE L (odd)
and LINE R (even) input signals are mixed before moving
into the AUX bus. These knobs should generally be set close
to the “t” (nominal) position.
NOTE
• To enable use of AUX5 and AUX6, you must turn on ( )
the AUX5/AUX6 switch (!5).
• For AUX1 to AUX4, you use the PRE switch (!3) to select
whether the pre-fader or post-fader signal is sent to the bus.
For AUX5 and AUX6, only the post-fader signal can be sent.
!3 PRE switch
Selects whether the pre-fader or the post-fader signal is fed to
the corresponding pair of AUX 1-4 buses. AUX1 and 2 and
also AUX3 and 4 should be paired. The upper PRE switch
controls the signal to AUX1 and AUX2; the lower switch
controls the signal to AUX3 and AUX4. If the switch is on
( ), the mixer feeds the pre-fader signal to the corresponding buses. If off ( ), the mixer feeds the post-fader signal.
!4 FX (effect) knobs (1, 2)
These knobs adjust the channel’s post-fader signal levels into
FX buses 1 and 2. On stereo channels, the LINE L (odd) and
LINE R (even) input signals are mixed before moving into
the FX bus. These knobs should generally be set close to the
“t” (nominal) position.
NOTE
If the AUX5/AUX6 switch is on, these knobs adjust the output
to the AUX5 and AUX6 buses.
!8 PEAK indicator
Lights red when the channel’s post-equalizer signal level
reaches 3 dB before clipping.
!9 SIG (Signal) indicator
Lights green when a signal is being input to the channel.
@0 Bus assign switches
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 bus.
• Switches 1-2, 3-4: Assign the channel’s signal to the
GROUP 1 to 4 buses.
• ST switch: Assigns the channel’s signal to the STE-
REO L and R buses.
NOTE
To send the signal to each bus, engage the ON switch (!7).
@1 PFL (Pre-Fader Listen) switch and indicator
When the PFL switch is turned on ( ) the indicator comes
on and the channel pre-fader signal is output to the MONITOR OUT and PHONES jacks for monitoring.
@2 Channel fader
Adjusts the output level of the input channel signal. Use these
faders to adjust the balance between the various channels.
NOTE
To reduce noise, set the fader sliders for any unused channels
all the way down.
!5 AUX5, AUX6 switch
Selects whether the channel’s post-fader signal is sent to
AUX buses 5 and 6 or FX buses l and 2. If the switch is on
( ), the signal goes to AUX5 and 6 buses; if off ( ), the
signal goes to the FX buses.
!6 PAN knob (Mono channels)
BAL knob (Stereo channels)
These knobs set the stereo pan position and determine the
volume balance between left and right. When the channels
are panned hard left or hard right, sound is heard from only
the hard-panned channel.
The PAN knob determines each mono signal’s pan positioning between left and right, while the BAL knob determines
the stereo channel’s volume balance between left and right.
!7 ON switches
Turning this switch on ( ) sends that channel’s signal to
the buses. When the switch is turned on, the switch’s lamp
comes on. If you turn the switch off ( ), all of the signal
sent to the buses such as AUX and GROUP buses is cut off.
NOTE
• The ON switch does not affect the operation of the PFL
switch (@1). You can monitor the channel’s pre-fader signal
through the PHONES jack even when the ON switch is off.
• To reduce noise, turn all unused channels off.
