True Diversity Set One Drag Two Wireless Microphone

1.UHF band transmits signals,frequency range :640-690MHZ；

2.Double channel receive signal,each channel has 100 signals to choose ,each channel step 250KHz;each channel use 25Mhz*2=50MHZ 

3.Adopts stable PLL  digital phase-locked loop synthesis technology and intelligent digital circuit, the performance and stability of the whole machine are significantly improved; 

4.Each channel match single ID number ,increasing interference function ,supports 6 stack machines (i.e. 6 receivers and 12 transmitters); 

5.Built-in effect noise suppression circuit, anti-whistling function is significant; 

6.The back of receivers set 4 rubber receive antenna,increasing the signal of receive ,garious appreace ;

7.The back set 2 balance output and 1 mix unbalanced output,suitable for connect various external equipments; 

8.No longer be liminted on -when launched just match mono channel ,to realize the same transmission can be interused in two channels 200 channels, showing the humanized high-tech design; 

9.Ultra-silence touch switch ,slightly press 0.5s enter into the status of working ; 

10.The consumption of microphone is 80mA,using 1.5v battery(2 capsules) for power supply ,can be continuously use 6h(when match high battery). 

11.The host and transmitter are equipped with LCD screen to display the working status and other content; 

12.Using distance : Open environment :100-150M  Complex environment:80-100M

13.Be suitable for various occasions such as conference and lecture ...
