MGP32X/MGP24X Owner’s Manual

Introduction

Main features

D-PRE (Discrete Class-A MIC preamp)

Mono input channels are equipped with Class-A discrete micro-

phone preamplifiers. The head amplifier features an inverted Dar-

lington 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.

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 tech-

nology specifically for the MGP to create an EQ with exception-

ally musical characteristics. Furthermore, the cutoff frequency

can also be adjusted, enhancing use of the EQ in sound reinforce-

ment 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 out-

put signal, and with a graphic equalizer (GEQ) that adjusts sound

quality such as feedback.

Digital effects — REV-X and SPX

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 appli-

cations, such as reverb, delay, and modulation effects, along with

complex combinations of multiple effects.

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.

About the models

The MGP32X and MGP24X feature a different number of mon-

aural 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 chan-

nels 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 addi-

tional control of your MGP mixer’s DSP settings via your iPhone,

iPod touch, and iPad. See the following web site to download the

order: peripheral devices (instrument, micro-

phone, iPod)  MGP mixer  power amps (or

powered speakers).

Reverse this order when turning the power off.

CAUTION

• Be sure to turn the power on/off in this order 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.

Getting sound to the speakers

1. While producing sound on your instrument or

microphone, adjust the channel GAIN knobs

so that the corresponding peak indicators

flash briefly at the highest peak levels.

NOTE

• To use the level meter to get a more accurate reading of the

incoming signal level, turn on the channel PFL switch. Adjust

the GAIN knobs so that the PFL/AFL level meter indicator

only occasionally rises above the “0” level.

• The gain (volume) level of the audio files in the USB device

may be too high. Refer to the NOTE on page 35 to adjust the

volume.

• Note that the PHONES jack or MONITOR OUT jacks output

the pre-fader signal from all channels for which the PFL

switch is ON, so that those signals can be monitored.

2. Turn on ( ) the ON and ST (Stereo) switches

for each channel you are using.

3. Make sure that all the PFL and AFL switches

are off ( ).

4. Turn on ( ) the ON switch of the STEREO

q 26dB (PAD) switch

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 impor-

tant 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 phan-

tom 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

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.

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 com-

pressor operates.

NOTE

Avoid setting the compression too high, as the higher average

output level that results may lead to feedback.

!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 nat-

ural stereo image, and in which the pan is con-

trolled.

• 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 pro-

duces 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 (counter-

clockwise/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.

* 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.

Controls and Connectors

!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 corre-

sponding 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 correspond-

ing 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.

!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 position-

ing 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.

!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 MONI-

TOR 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.
