Audibax AWM 401 TD - UHF Wireless System with 4 Handheld Microphones (640–690 MHz, IR sync, 100 m)

Audibax AWM 401 TD - UHF Wireless System with 4 Handheld Microphones (640–690 MHz, IR sync, 100 m)

The Audibax AWM 401 TD is a professional wireless system that combines a 4-channel UHF receiver with four dynamic capsule handheld transmitters . It operates in the 640–690 MHz range with a 2×32 MHz bandwidth and allows infrared (IR) synchronization for quick and secure frequency assignment. Its PLL architecture, S/N > 105 dB(A) and THD < 0.3% at 1 kHz provide stable and clear transmission for events, educational settings, houses of worship, corporate venues, and rental applications , with a range of up to 100 m under ideal conditions.

The receiver features balanced XLR (250 mV/600 Ω) and unbalanced 6.3 mm jack (400 mV) outputs for connecting to mixing consoles, interfaces, or PA systems. Each handheld transmitter is powered by two AA batteries and delivers up to 30 mW RF , with a dynamic range ≥ 100 dB(A) and a frequency response of 50 Hz–15 kHz , capturing voices with punch and clarity.

Frequently Asked Questions

Can all four microphones be used simultaneously?
Yes. The system is designed for 4 simultaneous UHF channels within the available band.

How do I assign a frequency to each microphone?
Using IR synchronization : select the frequency on the receiver and align the transmitter's IR window within a few centimeters to copy it.

What outputs does the receiver offer?
Balanced XLR outputs (250 mV/600 Ω) for each channel and a mixed output on a 6.3 mm jack (400 mV).

What is autonomy?
Each transmitter uses 2 AA batteries ; battery life depends on the type of battery and usage conditions.
