OMNITRONIC UHF-604 4ch Handheld Wireless Mic System True Diversity UHF

The OMNITRONIC UHF-604 is a professional-grade, true diversity wireless microphone system designed for high-performance audio in large-scale events, stage productions, and multi-channel setups. Operating license-free on UHF 823–832 MHz and 863–865 MHz across much of Europe, this system delivers stable, interference-free performance with an operating range of up to 60 meters (line-of-sight).

Its multifunctional 4-channel receiver features automatic frequency scanning, ID transmitter verification, and the ability to run up to 24 transmitters in 2 frequency bands simultaneously. A 7-band graphic EQ allows fine-tuning of each channel’s sound, while ultra-low latency (<3 ms) ensures perfect audio synchronization. The receiver’s full-color TFT displays provide real-time monitoring of frequency, channel, group, and audio level.

Each included handheld microphone features a dynamic capsule with cardioid pickup pattern for excellent feedback rejection and clear, focused vocals. An onboard LCD screen displays frequency, RF level, mute status, and battery charge. With metal construction and robust rack-mount receiver design, the UHF-604 is built for demanding live environments.
