D-PRE (Discrete Class-A MIC preamp)
Mono input channels are equipped with Class-A discrete microphone preamplifiers. The head amplifier features an inverted Darlingon 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 mething for eliminating 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 technology specifically for the MGP to create an EQ qith 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.
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 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
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 accomodate 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. 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.
