The MG20 from Yamaha is a compact mixer capable of twenty simultaneous inputs and is ideal for live performances, recordings, lectures and more. The mixer features twelve mono mic/line combo input channels, and four stereo line input channels that can also be used as mono mic or line inputs.
Channels 1-20 are each equipped with D-PRE mic preamps, 3-band EQ, pan control and a high-pass filter, and channels 1-12 feature a sweepable midrange control. The D-PRE mic preamps feature an inverted Darlington circuit and switchable 48V phantom power for use with dynamic and condenser microphones. Channels 1-12 also feature 26dB attenuation switches for use with loud sound sources such as guitar amplifiers and drums, and there is a one-knob compressor on channels 1-8 to smooth out the dynamics of vocals and instruments to help them sit better in your mix.
