DETAILS

Tascam MZ-123BT Bluetooth Audio Mixer with 3 controllable output zones. 

The Tascam MZ-123BT is a compact 1U multi-channel, multi-zone audio mixer for professional installation.

It 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 two versatile mic inputs and automatic attenuation of background music for superior intelligibility during announcements or paging.

Audio Control and Routing for Separate Zones

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 environments.

Three Outputs with Euroblock Connectors

Three pairs of balanced stereo outputs featuring Euroblock connectors for fixed installations are accessible from the back panel. Each output can be set to output audio in mono or stereo.

External Bluetooth Antenna for Stable Wireless Connectivity

The MZ-123BT has a dedicated Bluetooth antenna on its front-panel which helps ensure consistent stability of the wireless signal and reliability when streaming source material from a Bluetooth enabled device – even in the most signal-challenged environments.

Dual Mic Inputs with Euroblock Connectors

For announcements or moderations, the MZ-123BT offers two microphone inputs, each with switchable +48V phantom power for condenser mics, talkover functionality and zone selection by front-panel push buttons.

Two mics can be connected via rear-panel Euroblock connectors while an additional XLR/TRS combo connector on the front panel allows an alternative microphone to be hooked up quickly and selected via a front-panel switch.

Three-Band Equalizer, Gain Control and Switchable High-Pass Filter

The back panel provides gain control knobs and three-band EQ (Low, Mid, High) along with a high-pass filter switch for each input for setting optimal input level, tonal quality and voicing character for each microphone.

Talkover Function for Clear Announcements

The Talkover function automatically detects microphone signal input during audio playback and attenuates background music levels in the selected zones for optimal intelligibility during announcements. Threshold level and timing (release time) can be adjusted with controls on the rear panel to allow precise activation of level reduction and smooth restoration of background music to pre-set levels.

Simple Layout for Ease of Operation
Intuitive front-panel control of channel volume, output level, zone selection 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 adjusted via dedicated knobs on the rear panel.

Compact 1U Rack Mount Size
With a 1U rackmount size, the MZ-123BT is designed to fit seamlessly in an installed AV rack, with an optimised depth that allows greater connection space for other AV equipment such as Tascam CD / Solid State players.
