Key specifications

How to use

Attach the lavalier microphone to clothing using the supplied clip, positioning the capsule approximately 15–25 cm below the chin and slightly off-center to minimize breath noise. Connect the microphone to a compatible UHF wireless transmitter that is tuned to 823.6 MHz, secure transmitter settings and perform a sound check to set gain and monitor for interference. For best results, avoid rubbing the capsule against fabric and check the transmission channel for clear reception before the event.

Recommendations

Use wind protection or a foam pop shield when performing outdoors or in environments with air drafts; perform a venue scan to ensure the 823.6 MHz frequency is clear of conflicting signals; keep transmitter and receiver firmware and batteries maintained to ensure consistent wireless performance.
