Yamaha MG20 20-Channel Analogue Mixer

The Yamaha MG20 is a twenty-channel analogue mixing console for live sound, rehearsal rooms and larger instrument setups. This is the standard MG20, not the MG20XU: it has no USB audio interface or onboard SPX digital effects. Twelve mono microphone and line channels are joined by four mono or stereo input sections, providing sixteen microphone inputs and twenty line inputs in total. Yamaha D-PRE microphone preamps, one-knob compression on supported channels, input pads and high-pass filtering provide practical control before signals reach the main mix. Four group buses and four auxiliary sends allow separate signal routing for monitors and external processing, while balanced XLR stereo outputs connect to suitable sound systems. The mixer provides forty-eight-volt phantom power for compatible microphones and uses an internal universal mains supply. The manufacturer lists a rack-mount kit and mains lead among the supplied accessories. Microphones, speakers, signal cables, external effects units and recording interfaces are separate. Its twenty-channel designation counts audio channels rather than twenty independent microphone preamps.
