Audibax Zone 240BT - 4-zone 70/100V mixer amplifier with Bluetooth and USB/SD/FM player (240 W RMS)

The Audibax Zone 240BT is a professional installation mixer amplifier that combines power, zone control, and an integrated media player in a compact 2U 19" rackmount form factor. It delivers 240 W RMS on a single power channel with 70/100 V line outputs and a low-impedance (4 Ω) output, ideal for public address and background music projects in restaurants, hotels, retail stores, offices, or public buildings. It features a USB/SD player with lossless format support, an FM tuner, and Bluetooth connectivity, as well as priority inputs (TEL/Chime/Fire) and a 100 V emergency input with 24 V triggering for integration with alarm and security systems.

• Construction and measurements : metal chassis, black color; approximate dimensions 484 × 89 × 340 mm (width × height × depth) and approximate weight 13 kg .

Product benefits

• One device for everything : microphone and line source mixing, playback from USB/SD/Bluetooth and FM radio without additional hardware.
• Zone coverage : activate or adjust the level in each of the 4 70/100 V zones to adapt the music or voice to each space.
• Integration into warning systems : TEL/Chime/Fire inputs with priority and 100V emergency input with 24V trigger for evacuations or mandatory messages.
• Clean and stable audio : low distortion and high signal-to-noise ratio, with a robust Class A/B stage for continuous operation.
• Quick installation : screw-on Euroblock terminals, XLR/Jack combo connectors and link output for expansion to other equipment or recording.

Use cases

• Hospitality and retail : background music differentiated by zones (lounge, bar, terrace, corridors) and promotional messages.
• Offices and business centers : internal announcements, public address system and background music by floor or department.
• Educational centers and public buildings : priority announcements and dissemination of security notices with emergency entrance.
• Gyms and wellness centers : music by area (cardio room, weight room, changing rooms) with independent control.

Frequently Asked Questions

• Can I use conventional 4–8 Ω speakers? Yes. In addition to the 70/100 V outputs, it has a 4 Ω output for low impedance (single power zone).
• What formats does it play via USB/SD? MP3, WAV, WMA, and FLAC . The supported file system is FAT16/FAT32.
• What is the Bluetooth range? Approximately 10 m in interference-free conditions.
• Can it be rack-mounted? Yes, it occupies 2U in standard 19" racks.
• How do the priority inputs work? TEL/Chime/Fire temporarily override other sources to ensure messages are heard clearly. The 100V emergency input with 24V control automatically switches all line speakers to the alarm signal.

Key technical details

• Controls : master and zone volume, tone (bass/treble) and source selector.
• Output connections : screw-on Euroblock terminals for 70/100 V lines and 4 Ω output; line out on RCA.
• FM tuner : 87.5–107.9 MHz with 75 Ω unbalanced antenna connector.
• Construction : High rigidity metal chassis for continuous use in fixed installation.
