1. Pro Wireless Transmission signal, the frequency range: 190MHz-280MHz; 
2. Eight-channel receive signal, fixed-frequency, A better sound quality and anti-jamming 
3. The use of stable PLL digital phase-locked loop synthesis technology and intelligent digital lines, machine performance stability significantly improved; 
4. Each channel is equipped with a unique ID number, enhanced anti-jamming function, support 2 stacked machine use (means 2 receivers and 16 transmitters can working at the same time); 
5. Built-in high-efficient suppression of noise lines, anti-whistle function significantly; pickup distance of 30-50CM; 
6. Receiver set the back of the two rubber receiving antenna to enhance the received signal, the appearance of generous decent; 
7. On the back with two balanced output and a mixed non-balanced output, suitable for connecting a variety of external devices; 
8. Flexible gooseneck microphone design, 360 ° all-round adjustment, microphone light ring instructions to speak the state. 
9. Microphone power consumption of 80mA, the use of  9V  battery power supply, can be used continuously for 12 hours; 
10. Both the host and the transmitter are equipped with LCD screen to display the working status and so on 
11. Use of distance: open environment: 100-150 m Complex environment: 50-100 meters 
12. Applicable to all kinds of meetings and lectures.
