Tascam MZ-123BT Multi-Zone Commercial Mixer

TASCAM's MZ-123BT is a compact, 1U multi-channel Bluetooth-enabled Multi-Zone Commercial Mixer that can assign background music and announcements to 3 discrete Zones. Building on the popularity and feature-set of its big brother, the 2U MZ-223; the MZ-123BT provides versatile routing, mixing and distribution of up to three channels of music and announcements. Suitable 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.

Applications

• Retail stores such as grocery stores, apparel stores, etc.: Set different background music on separate areas/floors, while the Talk Over function will help making easy-to-hear clear announcements by detecting mic input and automatically attenuating the background music volume.
• Restaurants, cafés and bars: Set different background music each one dedicated to the counter, hall, or kitchen on restaurants/cafes/bars. Easy Bluetooth® wireless playback can be also done using smartphones or tablets.
• Hotels: Structure environment-suited acoustic environments with the MZ-123BT - set different background music on individual zones like lounges or party rooms and turn down the volume to create a calm environment on restrooms.

Includes

• Power cord × 1
• Euroblock plug × 8
• Cable band kit × 1
• Rackmount screw kit × 1
• Owner's Manual (including warranty) × 1
• Bluetooth Antenna × 1

Features

• Discrete Zone Audio Control and Routing: 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 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.
• Three Input Channels: 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.
• Bluetooth Antenna for Stable Wireless Connectivity: 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.
• Dual Mic Inputs with Euroblock Connectors: 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.
• 3 Band EQ, Gain Control and High Pass Filter 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.
• Talkover Function for Voiceover Clarity During Announcements: 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.
• Simple Layout for Ease of Operation: 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.
• Compact 1U Rack Mount Size: The 1U rack mount size MZ-123BT is designed to fit seamlessly in an installed AV rack, with an optimized depth that allows greater connection space for integrated AV equipment such as TASCAM CD/Solid State Players.
