1.UHF frequency band transmission signal, frequency range: 500mhz-900mhz;
2. Two channels receive signals, 200 channels are available for each channel, and each channel steps at 250KHz; Each channel is 49.75mhz;
3. Stable PLL digital phase-locked loop synthesis technology and intelligent digital circuit are adopted to significantly improve the performance stability of the whole machine;
4. Each channel is equipped with a unique ID number to enhance anti-interference function and support the use of 40 overlapping machines (i.e., 40 receivers and 80 transmitters);
5. The built-in high-efficiency noise suppression circuit has prominent anti-roaring function;
6. Two rubber receiving antennas are set on the back of the receiver to enhance the received signals, and the appearance is generous and appropriate;
7. Two balanced outputs and one mixed unbalanced output are arranged on the back, suitable for connecting various external equipment;
8. It is no longer limited to single channel matching only for one transmission, so as to realize the same transmission can be used interchangeably in 400 channels of two channels. It is a humanized high-tech design.
9. Ultra-quiet light touch switch, press 0.5s to start working;
10. Flexible gooseneck microphones rod design, can be 360 ° full adjustment, cannot speak light ring indicating the status.
11. The microphone consumes 80mA of electricity and USES 1.5v battery (3 pieces) for power supply. It can be used continuously for 12 hours.
12. Both the host and transmitter have LCD display working status and other contents
13. Service distance: open environment: 80-100 meters
