Audibax AWM 403 TD - 4-Channel UHF Wireless System with Headsets, IR Sync and XLR/MIX Outputs

The Audibax AWM 403 TD is a professional 4-channel UHF wireless system with condenser headset microphones, designed for clear and stable voice in events, education, theater, worship, or corporate settings. The receiver employs PLL oscillation for precise and robust tuning and operates within a 640–690 MHz frequency range with a 2×32 MHz bandwidth , making it easy to find clean channels even in demanding RF environments. Infrared (IR) synchronization speeds up pairing of each beltpack, while balanced XLR outputs and a 6.3 mm jack MIX output provide flexibility for consoles, interfaces, and recording. With a 50 Hz–15 kHz frequency response , signal-to-noise ratio >105 dB(A) , and distortion <0.3% (1 kHz) , it delivers clear and consistent performance, along with a range of up to 100 m under ideal conditions.

Main features

• 4 independent UHF channels with PLL for stability and interference reduction.
• Operating range: 640–690 MHz • Bandwidth: 2×32 MHz • Compensation: ±45 kHz.
• IR synchronization for quick frequency adjustment between receiver and beltpacks.
• Audio : response 50 Hz–15 kHz, S/N >105 dB(A) , THD <0.3% .
• Receiver outputs : Balanced XLR (250 mV/600 Ω) and unbalanced MIX on 6.3 mm jack (400 mV).
• Microphones : 4 condenser headset microphones with max. SPL 130 dB , lightweight and fixed capsule.
