The components are built for regular stage use, offering quick setup, reliable RF performance and straightforward control options that help maintain consistent audio quality during performances.
Advantages
This set provides dependable wireless connectivity with a head-worn microphone that maintains consistent mic positioning for natural speech and vocals. The bodypack transmitter is compact and ergonomic for comfortable wearing and reliable operation, while the rack-mountable receiver supports professional integration into stage or broadcast racks. The system offers adjustable gain and frequency synchronisation between transmitter and receiver, helping reduce interference and save setup time. Durable construction and clear audio reproduction are intended to meet the demands of repeated live-use scenarios.

Key specifications
System configuration: head-worn microphone, bodypack transmitter, rack-mountable receiver
Transmission range: professional UHF wireless operation (typical line-of-sight range suitable for stage use)
Microphone type: headset-style condenser capsule for speech and vocal clarity
Audio characteristics: low noise, wide dynamic range appropriate for vocals
Controls: adjustable input/gain on transmitter and receiver controls for level matching
Sync: IR synchronization or automatic frequency matching between transmitter and receiver
Mounting: receiver fits standard 19" rack with included hardware
Power: receiver and transmitter powered according to standard battery or adapter options for the system
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.
