Audibax AWM 402 - 4-Channel UHF Wireless System with 4 Lavalier Microphones and Bodypacks (640–690 MHz)

Audibax AWM 402 - 4-Channel UHF Wireless System with 4 Lavalier Microphones and Bodypacks (640–690 MHz)

The Audibax AWM 402 is a four-channel UHF wireless system designed for professional applications in events, education, stage performances, and light broadcasting. It operates in the selectable 640–690 MHz range with a 2×32 MHz bandwidth and PLL (Plugin Lie) modulation for stable transmission. It includes four bodypack transmitters with mini-XLR connectors and condenser lavalier microphones , offering a frequency response of 50 Hz–15 kHz , a dynamic range ≥ 100 dB(A) , a signal-to-noise ratio > 105 dB(A) , and THD < 0.3% @ 1 kHz . Under ideal conditions, the operating range reaches up to 100 m , maintaining a clean and consistent signal.

The receiver features independent balanced XLR outputs per channel and a 1/4″ jack MIX output for summing all four channels when a simplified flow is required. Transmitter-receiver synchronization is achieved via infrared , and the RF output of the beltpacks reaches up to 30 mW , with a stability of < 30 ppm . The system is supplied as a complete package : central receiver, four beltpacks , and four lavalier microphones , all in a black finish.

Frequently Asked Questions

What's included in the package?
Central receiver, 4 bodypack transmitters and 4 lavalier microphones , plus standard power and antenna accessories.

What is the actual scope?
Up to 100 m in unobstructed spaces and with proper RF planning. In complex environments, the usable distance may be reduced.

Do you need a license?
The 470–694 MHz band is used for PMSE in many countries. Check local regulations before operating.

Integration and connections

• Receiver outputs : Use the balanced XLRs to route each channel to separate inputs on the console.
• If you need a fast flow, use the 1/4″ MIX output to sum all four channels to one input.
• Perform frequency scanning and synchronize each beltpack via IR to minimize interference.
