Lavalier microphone Omnitronic UHF-E Series 531.9 MHz — wired lavalier for UHF wireless systems

The Omnitronic Lavalier Microphone UHF-E Series at 531.9 MHz is a wired lavalier designed for use with compatible UHF wireless transmitter packs. It provides a discreet, close-range microphone solution for spoken-word applications where a compact microphone capsule and stable wireless transmission are required. The microphone is intended to be connected to a matching UHF transmitter operating on the specified frequency, offering clear capture of speech for presentations, interviews, broadcasting and stage use.

Advantages

The lavalier yields consistent speech intelligibility thanks to a small, well-shielded capsule placed near the sound source. Its low-profile form factor minimizes visual intrusion on clothing and accessories. Integration with UHF transmitter packs at the stated frequency enables reliable RF link performance in typical event and production environments. The microphone’s wired capsule-to-pack connection removes the need for handheld operation, allowing the wearer full freedom of movement while maintaining audio quality tailored to voice pickup.

Suitable for

• Presentations and corporate speeches
• Broadcast interviews and reporting
• Theatre and stage performances requiring discreet miking
• Video production and on-camera dialogue

Key specifications

• Microphone type: lavalier / lapel microphone for voice
• Intended connection: wired capsule to UHF transmitter pack (compatible with devices operating on 531.9 MHz)
• Pickup pattern: optimized for close-range speech (omnidirectional or near-omni characteristics suitable for voice)
• Physical form factor: low-profile capsule with clip for clothing attachment
• Cable: lead from capsule to transmitter connector (length depends on transmitter configuration)

How to use

Attach the lavalier capsule to the speaker’s clothing using the supplied clip, placing the capsule near the collar or lapel at a consistent distance from the mouth to maintain steady level and intelligibility. Route the cable discreetly to the paired UHF transmitter pack and connect securely to the transmitter’s mic input. Set the transmitter and receiver to the matching UHF frequency and perform a soundcheck to adjust transmitter gain and receiver levels to avoid clipping while preserving clear voice reproduction. Monitor the signal during use and reposition the capsule slightly if wind noise or clothing rustle affects the audio.

Usage recommendations

For best speech clarity, position the capsule 15–20 cm (6–8 inches) from the mouth, slightly off-center to reduce plosives. Use a small foam windshield in environments with breath or wind exposure. Verify compatibility of the lavalier connector with your UHF transmitter model and confirm operation on 531.9 MHz before live use.
