The MZ-372 is a rackmount mixer designed for fixed installations in hotels, conference centres, public facilities, theme parks or bars. It offers seven input channels, two pairs of main outputs and a sub output.

Six input channels can be used for microphones or line-level signals from analogue playback sources like media players, tuners or cassette decks, each equipped with gain controls, LED level meters, three-band equalizers and 100-mm faders. Up to three of these channels can be switched to phono to connect record players (turntables). An additional mic input with level control and two-band equalizer on the front side can be used for announcements or speech reinforcement. In this case, the built-in Talkover function can be used to automatically lower the volume of background music according to the mic volume.

Each of the two main outputs has its own level control and stereo LED level meter. An independent sub output with level control and mono/stereo selection can be used to drive an external master recorder or an additional room. And there is a headphones output with level control for pre-fader monitoring of selected input channels and the main output signal.
