New advantages:

1. 400 frequency channels can be choosen

2. Voice and information are fully digital encrypted transferred

3. Each channel has an independent ID code

4. The receiver has synchronously display the battery capacity of the microphones function

5. The receiver screen display the output volume settings synchronously.

6. The receiver with 10 SQ controls,visual display on the screen.

7. Has automatically search frequency function 

8. The receiver has one key operation, more intelligent.

9.The transmitter and receiver use high level LCD screens

10. Adopt Sync IR Frequency synchronization technology.
