Lavalier-microfoon Omnitronic UHF-E-Serie 831,1 MHz met zender

The Omnitronic Lavalier microphone UHF-E Series 831.1 MHz with transmitter is a hands-free vocal capture solution designed for presentations, interviews, stage and broadcast applications. The system combines a discreet lavalier-style mic capsule with a compact wireless transmitter operating in the UHF-E band at 831.1 MHz, allowing consistent close-mic pickup and freedom of movement during performances or recordings.

Advantages

The system provides compact placement and stable vocal pickup typical of lavalier microphones while using a dedicated transmitter to deliver wireless audio transmission at 831.1 MHz. Its design supports unobtrusive mounting on clothing and consistent distance from the sound source for predictable vocal clarity. Mobility is improved compared with wired lavalier setups because the transmitter enables cordless operation while retaining a direct lavalier pickup characteristic.

How to use

Attach the lavalier capsule to the presenter or talent at chest level using the supplied clip, positioning the capsule 15–25 cm from the mouth for a balance between clarity and plosive control. Connect the lavalier cable to the transmitter input and secure the transmitter to a belt or place it in a pocket. Power on the transmitter and the compatible UHF receiver, ensure the receiver is tuned to 831.1 MHz if manual tuning is required, and perform a sound check to set input gain on the receiver or mixing console. Monitor audio levels to avoid clipping and adjust clothing or capsule position if necessary for consistent vocal quality.

Recommendations

For best results, place the lavalier capsule on the chest center or slightly off-center, avoid contact with jewelry or fabrics that produce rustling, and perform a brief mobility test to verify stable RF link and consistent audio while moving. Use wind protection when recording outdoors and check that the transmitter battery is fully charged or replaced before extended use.
