A dual channel PLL(Phase Loop Lock) tunable UHF wireless system with a metal Hand Held microphone. The RF carrier frequency is selected on the receiver and synchronised to the transmitter via infra-red at the touch of a button. Up to 4 RU105 systems can be operated together on the AU licence-free band. The System has reliable auto-scan frequency paring and PLL function to keep away from any interfere environment. The system is easy to use, has excellent sound quality, multi-selective channels and is ideal for a range of different applications.

The digitally modulated transmission guarantees a trouble-free connection and minimises dropouts. The digital audio signal is characterised by excellent sound quality, excellent noise performance and very low distortion. The receiver has an advanced digital feedback processor to prevent whistling noises.
