How to use

Attach the lavalier microphone to the speaker’s clothing near the mouth, typically on the lapel or collar, ensuring the capsule is unobstructed and oriented correctly for voice capture. Power and sync the transmitter and receiver according to the system’s controls, select a clear channel within the 863–865 MHz range if multiple channels are available, and perform a sound check to set appropriate gain levels and confirm signal stability. Place the receiver in proximity to the transmitter to maintain a robust wireless link during use.

Recommendations

For best results, position the microphone 15–20 cm from the speaker’s mouth and avoid covering the capsule with fabric. Maintain line-of-sight or minimal obstructions between transmitter and receiver where possible and test signal quality in the actual venue to identify potential interference within the UHF band.
