The MGP 24X ( 24-Channel Analog Mixing Console with DSP Effects ) from Yamaha is a 24-track analog mixer with digital control and features 16 D-Pre microphone preamps, 24 line inputs, 6 auxiliary inputs, and 2 effects sends. It is designed for use in live sound environments, including clubs and houses of worship. Each channel has Yamaha's X-pressive 3-band equalizer and 1-Knob compressor, allowing channel-independent frequency and dynamic control. The MGP24X has an integrated DSP Hybrid Channel section that includes 3 types of reverb and 16 effects, as well as auto-ducker and auto-leveler functions that allow for hands-off monitoring of sources. The digital portion of the MGP24X also allows for iPhone and iPod touch control of a variety of parameters via the free MGP Editor app. You can also playback music from your iTunes catalog via the iOS input USB port, freeing up an analog input on the console. A second USB port allows you to record your live performance directly to external USB media, as either a stereo WAV or MP3 file.
