-
Auto channel synchronization
After selecting a clean channel on the receiver, a single button will quickly synchronize the transmitter's channel. 100 preset channels available for selection.
-
No more noise
Proprietary pilotone, noise-detector and squelch circuits prevent noise interference. Adjustable SQ to increase receiver range with higher sensitivity and reduce interference with lower sensitivity.
-
Real-time indicators
The LED indicators on the front panel can monitor the RF reception status as well as the volume status of the connected transmitter for the audio engineer to handle and ensure the best sound quality.
-
Smart assembly structure
Unique slide rail structure toollessly combines two receivers into 1U for easy mounting on the cabinet.
