How to use

Attach the head-worn microphone so the capsule sits near the corner of the mouth for natural speech pickup and minimal plosive noise. Clip the bodypack transmitter to clothing or a belt and connect the headset cable to the transmitter securely. Mount the receiver into a rack or place it on a stable surface and connect to the PA or mixing console via balanced audio outputs. Power on the receiver first, then the transmitter. Use the receiver’s display and controls to select a clear frequency and perform an RF/IR sync to transfer settings to the transmitter. Adjust input gain on the transmitter and output level on the receiver so the signal remains clean without clipping throughout the performance.

Usage recommendations

To maintain stable wireless performance, perform a frequency scan before each event to avoid interference, keep a clear line of sight between transmitter and receiver where possible, and use fresh batteries or a reliable power source for the transmitter. Position the headset microphone consistently for uniform sound, and test levels during soundcheck to set appropriate gain staging. Store the system in its case when not in use to protect connectors and capsules.
