Soundcraft MH3 32 Mono + 4 Stereo Channels Console
The Soundcraft MH3 is a professional, large format sound reinforcement console that’s designed for front-
This model is configured with 32 input channels. 32 inputs feature microphone and line level connections, an additional 4 stereo inputs are provided as well. The stereo inputs enable flexible auxiliary routing for monitoring mixing applications. The console features 8 group outputs enabling routing to monitors, external recorders, etc. The MH3 series implements Soundcraft’s microphone preamps and EQ section, delivering the sonic quality expected of more costly consoles.
Additional features include a 12 x 4 matrix mixer (expandable to 12 x 8) for added routing flexibility and an integrated meter bridge, enabling accurate metering.
