TASCAM MZ-123BT 3-Zone Commercial Audio Mixer with Bluetooth
The TASCAM MZ-123BT is a compact 1U multi-zone commercial audio mixer designed to distribute music and announcements to up to three independent audio zones. With three source channels, two microphone inputs, Bluetooth audio, and flexible zone routing, the MZ-123BT is well suited for restaurants, retail stores, cafés, hotels, fitness facilities, offices, and other commercial audio installations.
Each input source can be assigned to the desired zone outputs, allowing different areas of a facility to receive independently controlled audio. Two microphone inputs support announcements and paging, with automatic background-music attenuation to improve speech intelligibility when announcements are made.
The MZ-123BT also provides Bluetooth 4.2, stereo RCA inputs, a front-panel 3.5mm AUX input, balanced Euroblock zone outputs, and headphone monitoring in a rackmount chassis.
Three Independent Audio Zones
The MZ-123BT provides three discrete balanced zone outputs, each with its own volume control.
Audio sources can be assigned to individual zones using the front-panel routing controls, making it possible to distribute music and announcements to different rooms or areas from a single mixer.
This is useful for applications such as a restaurant with separate dining and bar areas, a hotel with multiple common spaces, or a retail facility requiring independent audio distribution.
Three Music Source Inputs
The TASCAM MZ-123BT provides three source channels for background music and other program audio.
Channels 1 and 2 use rear-panel stereo RCA line inputs for connecting media players and other line-level audio sources.
Channel 3 can receive audio through the front-panel 3.5mm AUX input or Bluetooth, providing a convenient way to connect compatible phones, tablets, computers, and other playback devices.
Each source channel includes volume adjustment and routing controls for assignment to Zones 1, 2, and 3.
Bluetooth 4.2 Audio Streaming
Built-in Bluetooth 4.2 provides wireless audio playback from compatible Bluetooth devices.
The MZ-123BT supports:
- A2DP profile
- SBC codec
- AAC codec
- Qualcomm® aptX™ audio
- SCMS-T content protection
The specified unobstructed Bluetooth transmission distance is approximately 10 meters, although actual range can vary depending on the installation environment and surrounding radio conditions.
Two Microphone Inputs for Paging and Announcements
The MZ-123BT provides two microphone inputs for paging, announcements, and voice applications.
The front microphone connection supports balanced XLR and 1/4-inch TRS, while rear-panel microphone connections use balanced Euroblock connectors.
Automatic attenuation of background music allows microphone announcements to take priority when required, helping maintain speech intelligibility in commercial environments.
Balanced Zone Outputs
All three zone outputs use balanced Euroblock connectors for integration with professional and commercial audio equipment.
The outputs provide a rated level of +4 dBu with a maximum output level of +24 dBu, making the MZ-123BT suitable for connection to compatible commercial amplifiers and other downstream audio equipment.
Headphone Monitoring
A front-panel 1/4-inch stereo headphone output allows monitoring of the system's output channels.
This provides a convenient way for installers and operators to check audio without having to monitor each zone from its physical location.
