The MZ-372 allows multiple audio sources (19 total) to be mixed, muted, and routed to 2 redundant outputs, controlled by familiar volume sliders and assignment buttons. Input signals can be inserted via 6 audio channels, each consisting of 2 sets of unbalanced RCA stereo pairs, and 6 XLR inputs for a total of 12 sets of RCA inputs and 6 XLR inputs. In addition, channels 2/3/4 can be set to accommodate phono-level signals for use with a turntable. Lastly, and located conveniently on the front panel, one additional XLR input is available driving a studio quality mic preamp and ducking circuit for easy voiceover and announcement work.

Twin outputs each feature a combination of balanced XLR or RCA unbalanced connectors for easy integration into virtually any audio system. This flexibility allows combinations of microphones, CD/DVD/Blu-ray players, instruments - or any other audio source - to be selected or muted, and sent simultaneously to the dual outputs, each with it’s own volume control. Finally, the convenient "Talkover" function will automatically lower any mixed channel source so the microphone connected to the front panel can easily be can be heard in whichever zones you choose.

Familiar volume sliders, switches/buttons, EQ knobs, and mute buttons make the MZ-372 simple and fast to operate and set up. There is even a master recording stereo output, which can send audio to an external recorder which makes event or music performance capturing easy. The Booth outputs provide another stereo feed with independent control for additional monitoring.
