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.
