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 environment. 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. Three Stereo Input Channels for Playback Sources Two stereo line inputs (RCA, unbalanced) allow connection of AV equipment such as Tascam CD / Solid State Players or similar playback devices. Channel 3 has an Aux/Bluetooth input that allows an additional audio source to be connected via Bluetooth or 3.5-mm mini plug. Each input features a volume control knob as well as three zone routing buttons for audio distribution to desired areas or rooms. 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.
