New advantages:

1. Wide band frequency (600MHz - 900MHz): total 400 channels, one frequency band can be installed in 200 compartments.

2. The real digital wireless microphone (voice and signal are fully digital encrypted transferred), strongly confidential transmission, can search the cleanest frequency point for each microphone faster and better to ensure microphones sound with higher consistency.

3. Each channel has an independent ID code, the same frequency points from outside will not interfere with the receiver.

4. The receiver with built-in microphone battery capacity synchronous display function.

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

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

7. The receiver has automatically search frequency function.

8. Plating handheld microphone, study and durable .

9. After heat treated for the brazing metal net and reinforce with hexagonal screw would effectively prevent the microphone from damage  when fall from height or being intense collision.
10. Microphone cartridge, the capacity of climate resistance is strong and the stability is good
