Tascam MZ-123BT Commercial Multi-zone Audio Mixer With Bluetooth

Tascam MZ-123BT Commercial Multi-zone Audio Mixer With Bluetooth

The Tascam MZ-123BT is a 1U rackmount zone mixer designed for one job: getting the right background music and announcements to the right parts of a building, reliably, every day. It serves three independent output zones from three stereo input channels, two RCA line inputs for fixed sources such as media players, plus a third channel that switches between a front-panel 3.5 mm aux input and a built-in Bluetooth receiver for wireless streaming from a phone or tablet. Two microphone inputs with talkover ducking handle paging and announcements, automatically dipping the music so speech stays intelligible, then restoring it afterwards. Restaurants, retail stores, hotels, cafes, gyms and corporate spaces are its natural habitat, anywhere music needs to run all day without an engineer standing over it.

• Each zone output switchable between stereo and mono
• Compact 1U rackmount chassis, 3.0 kg

Zone routing made simple

Every input channel has its own volume control and zone assignment buttons, so the person running the venue decides per source which zones hear it: the lunch playlist in the dining room, a different level in the bar, nothing but announcements at reception. Zone outputs sit on balanced Euroblock connectors, the fixed-installation standard, with rated output of plus 4 dBu and a healthy plus 24 dBu maximum for driving long cable runs to remote amplifiers without noise. A mono and stereo switch per zone handles speaker layouts honestly, summing correctly for single-ceiling-speaker areas instead of losing half the programme. Front-panel signal and peak indicators per zone, plus a headphone output with zone monitor selection, make fault-finding a matter of seconds.

Announcements that cut through

Paging is where zone mixers earn their keep, and the MZ-123BT treats it properly. Mic 1 can be connected at the front panel through an XLR and TRS combo jack for walk-up use, or at the rear on Euroblock alongside Mic 2 for fixed gooseneck or wireless receiver feeds. Each mic input has switchable 48 V phantom power for condenser microphones, a 39 dB gain adjustment range, 3-band EQ set from the rear panel, a high-pass filter to strip handling rumble, and a pad for hot sources. The talkover function detects speech and attenuates the music inputs, with threshold and release time adjustable on the rear panel so the ducking feels natural rather than abrupt.

Bluetooth and everyday sources

The third input channel is built for how venues actually source music now. A front-panel Bluetooth antenna gives the built-in receiver a stable link to a manager’s phone or a dedicated tablet, with SBC, AAC and Qualcomm aptX codec support, and a pairing button on the front panel keeps connection simple for staff. When a wired source is preferred, the 3.5 mm aux input on the same channel takes any player. The two RCA line inputs accept CD and media players, tuners and streaming boxes at standard minus 10 dBV level, each with rear-panel gain trim to balance sources of different loudness so channel volume controls behave consistently.

Built for the rack and the long term

The mixer occupies a single rack unit at 483 x 46.5 x 274.8 mm, weighs 3.0 kg, runs on 100 to 240 V AC and consumes 25 W. Audio performance is specified at a 20 Hz to 20 kHz frequency response, signal-to-noise above 90 dB and crosstalk above 80 dB, figures that keep background music clean at the low listening levels commercial spaces use. Set-and-forget controls live on the rear panel where customers cannot disturb them, daily controls live on the front, and that separation is exactly what an installed system needs to keep sounding right month after month.
