The MZ-223 is a rackmount mixer designed for fixed installations in shops, public facilities, restaurants, bars, theme parks or hotels. It can be used to send background music and announcements from a variety of sources to three different rooms or zones. Each of the seven input channels can be routed to any or all of the three output zones.
The mixer offers five stereo input channels for line-level signals from analogue playback sources like media players, tuners or cassette decks. Two channels can be switched to phono to connect record players (turntables). Each channel has its own gain control, peak LED and level fader. Two additional microphone input channels – with level controls, LED level meters and 3-band equalizers – are available for announcements, speech reinforcement, karaoke or other uses with dynamic microphones. When used for announcements, for example, the built-in Talkover function can automatically lower the volume of background music according to the mic volume.
Each of the three zone main outputs is equipped with level control, LED level meter and a 3-band equalizer. There is also an independent monitoring output for the control room and a headphones output with level control that can be used for pre-fader monitoring of selected input channels and any of the zone outputs.
