Omnitronic UHF E-FLEX Handheld Microphone 823–832 / 863–865 MHz (MPN 13063372)

The Omnitronic UHF E-FLEX Handheld Microphone operates on UHF frequency ranges 823–832 MHz and 863–865 MHz and is intended for wireless vocal and speech applications. The microphone is a cordless handheld transmitter designed to work with UHF receiver systems tuned to the same bands, allowing freedom of movement on stage, in presentations, or during public address situations.

Advantages

The handheld design provides wireless mobility while maintaining a form factor familiar to vocalists and presenters. Operating within the UHF bands 823–832 MHz and 863–865 MHz, the microphone offers a stable radio link when paired with compatible UHF receivers. Its construction supports typical live-use handling and quick placement in standard microphone clips or stands.

Suitable for

• Live vocal performances and stage use
• Presentations, conferences, and public speaking
• Houses of worship and community events
• Temporary PA setups and mobile event rigs

When it may not be suitable

This microphone requires a compatible UHF receiver operating in the same frequency ranges (823–832 MHz or 863–865 MHz); it will not function as a stand-alone system without such a receiver. It may not be appropriate in environments where those UHF bands are restricted or heavily congested by other services, or where regulatory allocation differs from the specified ranges.

Key specifications

• Operating frequency ranges: UHF 823–832 MHz and 863–865 MHz
• Form factor: handheld wireless transmitter
• Intended application: vocal and speech transmission
• Compatibility: requires UHF receiver tuned to the same bands

How to use

Install appropriate batteries or charge the transmitter as specified by the manufacturer's instructions, then power on the handheld unit. Ensure your UHF receiver is powered, set to the matching frequency range and channel, and that both transmitter and receiver are within recommended operating distances for reliable reception. Perform a soundcheck to set gain levels and check for interference prior to live use. Place the microphone in a clip or hold it at a comfortable distance from the mouth to achieve desired vocal clarity.

What to consider before purchase

• Availability and legal use of the specified UHF frequency ranges in your country or region
• Compatibility with your existing UHF receiver or the need to purchase a receiver that supports 823–832 MHz / 863–865 MHz
• Battery type and expected runtime for the handheld transmitter
• Stage environment and potential RF interference sources

Usage recommendations

For reliable operation, pair the Omnitronic UHF E-FLEX handheld microphone with a UHF receiver confirmed to support the same frequency ranges, perform a pre-event frequency scan to avoid interference, and allow a short warm-up and soundcheck period to adjust levels and placement for consistent vocal reproduction.
