MK-819

1.Adopt 4 antennas and dual channel single receiving system , self develop the particular high sensitivity Collection – circuit , is able to eliminate fault frequency happened 2. Dual channel AFS frequency automatic search function independently. Can search the cleanest channel at the working environment Automatically 3. The frequency can be synchronized between receiver and transmitter via infrared. 4.Professional performance level phase locking loop (PLL) circuit ,coordinate the noise locked squelch control technology and digital pilot technology , digital pilot control will make the AF signal to be mute tu restrain noise when transmitter turn off , meanwhile receiver is mute to cut off interference signal . 5. LED screen display the RF and AF signal , battery status , channel of A/B switch, work frequency, frequency group , channels and so on . 6. SQ receiving distance at -65~-100dBm is adjustable .and have operating locked function , prevent misoperation. 7. FULINDA self develop audio system , high-dynamic respond and wide frequency respond . Eliminate noise brought by the high frequency, achieve excellent sound quality 8. Self development of core technology "VCO and RFcircuit", make more available bandwidth, and signal receiving more stable.
