## Long description

Omnitronic UHF-604 is a four-channel wireless microphone system operating in the 520–554 MHz UHF band. The receiver provides four independent channels for vocal or instrument amplification and is intended for live events, presentations and small venues where multiple microphones are required. The system is designed for stable RF transmission and supports simultaneous use of up to four transmitters with quick channel selection within the specified frequency range.
Advantages
The UHF-604 delivers four independent channels in a compact rack- or shelf-mountable receiver format, enabling multi-microphone setups without complex cabling. Operating in the 520–554 MHz range, the system offers reliable line-of-sight RF coverage for short- to medium-range applications. Simple channel switching and clear vocal reproduction make it suitable for speech and live performance use. The design focuses on functional usability, providing an efficient solution for small venues and mobile setups.
Suitable for
 Small live performances and stage shows
 Corporate presentations and conferences
 Houses of worship and community events
 Mobile DJs and event technicians
 Backup or expansion of fixed sound systems
When it may not be suitable
This system is intended for short- to medium-range applications and small to medium venue installations. It may not be suitable for very large venues or outdoor events requiring long-range coverage or advanced frequency coordination across many wireless channels. For installations requiring wide-area coverage, networked distribution, or integration with complex RF management systems, a higher-end multi-channel solution with professional coordination may be more appropriate.
Key specifications
 Number of channels: 4 independent UHF channels
 Operating frequency range: 520–554 MHz
 Typical use: vocal and instrument wireless transmission
 Receiver type: multi-channel UHF receiver (rack- or shelf-mountable form factor)

How to use
Install the receiver in a suitable position with a clear line of sight to the performance area to optimise RF reception. Connect the receiver's audio outputs to a mixing console or amplifier using standard audio cables. Power on the receiver and the wireless transmitters, select matching channels within the 520–554 MHz band for each transmitter and verify audio levels on the mixer. Position the transmitters on performers or instruments and perform a soundcheck to set gain and check for interference. If interference or dropouts occur, try adjusting receiver placement, antenna orientation or select an alternate channel within the available frequency range.
What to consider before purchase

 Venue size and expected RF range (short- to medium-range suitability)
 Local regulations and permitted frequency ranges for wireless audio in your country
 Compatibility with existing mixing consoles and cabling (audio output type)
Usage recommendations
For best performance, mount the receiver in a central, elevated position with antennas spaced and oriented to minimise interference. Perform a frequency scan and soundcheck before events, and keep spare batteries for handheld or bodypack transmitters to ensure uninterrupted operation.
