Omnitronic UHF-604 4-Channel Wireless Microphone System (823–832 / 863–865 MHz)

Need to mic up an entire panel, a small theater cast, or a multi-vocal live band without overcrowding your gear rack? The Omnitronic UHF-604 is a professional 4-channel true diversity wireless microphone system that packs four independent channels into a single, compact 1U rack-mount receiver.

Engineered for rock-solid stability and pro-tier acoustic performance, this all-in-one system eliminates dropout anxiety and simplifies multi-mic cable clutter.

Key Features & Benefits

Four Channels, One Rack Unit: Efficiently run 4 separate handheld wireless microphones simultaneously while occupying just 1U of your standard 19-inch rack space.
True Diversity Signal Lock: Each channel utilizes high-quality true diversity reception. By housing dual antennas and constantly switching to the strongest signal path, the receiver effectively isolates your audio from dropouts and dead zones up to a 60-meter line-of-sight range.
Color-Coded TFT Ecosystem: Stay completely organized during hectic live events. The receiver features 5 vibrant, multicolor TFT displays that allow you to color-code channels for immediate tracking of frequency, group, mute status, RF signal level, and audio behavior.
Intelligent Auto-Scan & ID Sync: Avoid frequency overlaps. The system automatically scans for the cleanest frequencies across the UHF 823–832 MHz and 863–865 MHz bands (both license-free across most of Europe). Built-in ID transmitter verification ensures that external interference can't hijack your signal.
Onboard 7-Band Graphic EQ: Shape the vocal character of your performers right from the hardware menu. The integrated 7-band equalizer gives you instant control over room acoustics and vocal clarity without needing external processing gear.
