TASCAM MZ-123BT Commercial-grade Multi-Zone Audio Mixer

The TASCAM MZ-123BT is a compact 1U multi-channel, multi-zone professional installation mixer that provides versatile routing, mixing and distribution of up to three channels of music and announcements for a wide range of commercial applications, including retail, restaurants, bars, cafes, hotels, or any environment that requires independent audio routing and announcement capabilities. Featuring a simple, intuitive layout for ease of operation, the Bluetooth®-enabled MZ-123BT comes equipped with 2 versatile mic inputs and automatic attenuation of background music for superior intelligibility during announcements or paging.

Three discrete Zone Outputs with Volume control allow routing of background music to desired areas or rooms in a restaurant, hotel, retail store or other commercial environment.

Three pair of stereo outputs featuring Euroblock connectors for fixed installations are accessible from the back panel. A MONO/STEREO switch is provided for each output.

Stereo LINE Inputs 1 and 2 (RCA, Unbalanced) allow connection of AV equipment such as TASCAM CD/Solid State Players or similar playback devices. The Channel 3 AUX/Bluetooth® Input allows an additional audio source to be connected via Bluetooth® or 3.5mm mini plug. Each input features a Volume Control knob as well as a Zone Routing button (1, 2 or 3) for audio distribution to desired areas

A dedicated front-panel Bluetooth® antenna helps ensure consistent wireless signal stability and reliability when streaming source material from a Bluetooth® enabled device — even in the most signal-challenged environments.

Two Mic Inputs, each with +48V phantom power switches, enable discrete Zone talkover or announcer functionality via push-button front panel Zone Output switches. Two rear panel Euroblock connectors are provided for Mic 1 and 2 connection, with XLR/TRS connectivity for Mic 1 easily accessible from the front panel and selectable via a front panel switch.

On the back panel, separate 3 band EQ (Low, Mid, High) and Gain control knobs, along with a High Pass Filter switch are provided for setting optimal room level, tonal quality and voicing character for each mic channel.

The Talkover function automatically detects mic signal input during audio playback and attenuates background music levels in the desired Zone for optimal intelligibility during announcements. Back panel adjustment of Mic Threshold Level and Timing (release time) allows smooth restoration of background music to pre-set levels.

Intuitive front-panel control of Volume, Output, Zone Select and Bluetooth® pairing makes basic operation simple for non-technical staff and workers. More advanced system configuration and operational settings for EQ, Gain and Threshold can be dialed in and set via dedicated back panel knobs.
