Audibax AWM 203 - 2-Channel UHF Wireless System with 2 Headset Microphones and 200 Frequencies (640–690 MHz)

Audibax AWM 203 - 2-Channel UHF Wireless System with 2 Headset Microphones and 200 Frequencies (640–690 MHz)

The Audibax AWM 203 is a professional 2-channel analog UHF (FM) system that includes a dual receiver , two bodypack transmitters , and two condenser headset microphones . Designed for events, conferences, education, and performances, it offers 200 adjustable channels within a 50 MHz bandwidth ( 640–690 MHz range) for flexible operation and minimal interference. The receiver provides independent balanced outputs per channel (A/B) and an unbalanced 6.3 mm mixed output , while the bodypack transmitters use mini-XLR connectors and incorporate a PLL oscillator for stable transmission. With a frequency response of 50 Hz to 15 kHz , a dynamic range of up to 100 dB , and a maximum deviation of 45 kHz , the AWM 203 delivers clear and consistent voice with complete freedom of movement. The bodypack transmitters are powered by two AA batteries (not included), simplifying everyday operation.

Main features

• Dual UHF channel (640–690 MHz) with 200 selectable frequencies over 50 MHz.
• Condenser headset microphones with mini-XLR connection to beltpacks.
• Receiver with balanced XLR A/B outputs + unbalanced 6.3 mm mixed output ; IR synchronization and auto-frequency scanning.
• Audio : 50 Hz–15 kHz, dynamic range up to 100 dB; receiver stability ±0.1% and transmitter stability <30 ppm .

• Professional connectivity : XLR outputs per channel and 6.3 mm mixing for integration into analog or digital consoles.
• Total mobility : lightweight headband, compact battery packs and universal power supply with AA batteries.

Use cases

• Events and corporate : presentations, keynote speeches, trade fairs and training.
• Education and worship : teachers, speakers and officiants with hands free.
• Theatre and live performance : actors, dancers and stage technicians who require a headset.
• Fitness and leisure : gym instructors and group fitness classes.

Frequently Asked Questions

• What's included in the pack? 1 dual receiver, 2 beltpacks and 2 headsets .
• Can the output of both channels be mixed? Yes, in addition to the independent XLR A/B outputs, the receiver has a 6.3 mm MIX output .
• What power source do the flasks use? 2 AA batteries per flask (not included).
• Can I use it in any country? It operates in the UHF 640–690 MHz band. Always check local spectrum regulations before operating.

Usage recommendations

• It performs a frequency scan and infrared (IR) synchronization of each belt with the receiver before the event.
• Place the receiver antennas visible and away from sources of interference (routers, metal, dimmers).
• Adjust levels avoiding saturation at the beltpack and table input; use filters/low-pass filters according to the environment.
