Audibax Zone 360BT - 4-zone 100V mixer amplifier with Bluetooth and USB/SD/FM player

The Audibax Zone 360BT is an installation mixer amplifier that integrates power, zone matrix, and media player into a single 19" 2U chassis. Designed for public address and background music systems, it offers four independent, switchable 70/100V line zones with per-zone volume control, as well as a low-impedance 4Ω output for spot applications. It features Bluetooth, a USB/SD card reader, and an FM tuner, allowing for local audio playback without external equipment. Its Class A/B electronics, 20Hz–20kHz frequency response, and SNR > 90dB ensure clean and stable playback in commercial and corporate environments.

Main features

• 4 zones 70/100 V with individual selection and volume per zone .
• Total RMS power: 360 W on 100 V line (equivalent impedance 28 Ω for 360 W).
• Additional Low-Z output : 4 Ω (mono).
• Integrated player with USB/SD, Bluetooth 2.0 (max. range 10 m) and FM radio (87.5–107.9 MHz).
• Complete mixer : 2 balanced MIC inputs with 15V phantom power , 1 combo MIC/LINE input with priority and 2 stereo line inputs (RCA).
• Priority inputs for chime , fire alarm and telephone; 100V emergency input with 24V control.
• Protections : short circuit/DC, over-temperature, overload and limiter; fan cooling .
• Audio : 20 Hz–20 kHz response, THD+N < 0.5% , crosstalk > 70 dB , damping factor 150 .
• Output connectivity : Euroblock/screw terminals and RCA line out .
• 19” (2U) rack format with robust metal chassis.

Product benefits

• All in one : mixing, powering and playback from the same unit to simplify installation and maintenance.
• Real zone management : switch activation and dedicated volume per zone , ideal for adjusting levels in rooms, hallways or outdoors independently.
• Integration into notification systems : prioritization by Chime/Fire/TEL and 24V switched emergency input to comply with evacuation and messaging procedures.
• Flexible connectivity : Bluetooth for mobile content, USB/SD for local playlists and FM for continuous broadcasting without additional sources.
• Quality and stability : Class A/B electronics with complete protections and active ventilation for continuous use in professional environments.

Use cases

• Hospitality and retail : differentiated background music by area (lounge, bar, terrace) and clear voice announcements.
• Offices and coworking : internal announcements, waiting rooms and common areas with independent levels.
• Gyms and sports centers : musical programming by area and priority public address system.
• Schools and public buildings : doorbell/alarm, telephone notifications and 24V emergency entrance.
• Small places of worship and multipurpose rooms : microphones with 15V phantom power and local sources without the need for extra equipment.

Frequently Asked Questions

• Can I use 70V and 100V speakers? Yes. The amplifier works with 70/100V lines (in addition to a 4Ω output). Do not mix 70V and 100V on the same line.
• Can I connect an 8 Ω speaker? The Low-Z output is rated for 4 Ω . With 8 Ω, it will operate at less power; do not use Low-Z at the same time as the 70/100 V outputs.
• What formats does the player play? MP3, WMA, WAV and FLAC from USB/SD with FAT16/FAT32 file systems.
• Does it support condenser microphones? Yes, on MIC 1–2 using switchable 15V phantom power .
• Can alerts be sent from a telephone switchboard? Yes, via priority TEL entry .

Connectivity and control

The front panel features per-channel level controls, 2-band EQ on the main output, and switchable zone selectors . The rear panel includes XLR/6.3 mm combo jack connectors, stereo RCA inputs, Euroblock terminals for Chime/Fire/TEL , and 70/100 V, 4 Ω speaker outputs, as well as a link output for daisy-chaining multiple units.

Installation and reliability

The 2U metal chassis with forced ventilation is designed for 19” racks. The system integrates protection against short circuit/DC, overload, over-temperature and a limiter , offering stable operation in continuous use.
