Using UHF550-980 MHZ band, application of PLL phase-locked loop frequency synthesis technology, frequency adjustable, the transmitted power is adjustable, avoid interference frequency, the mobile phone. Integration of the central processor CPU bus control, combined with digital LCD display interface, operation, outstanding performance.
Using multi-stage narrow-band high frequency and medium frequency frequency selective filter, fully eliminate the interference signal.
Use the extended audio compression technology, greatly reduce noise, dynamic range.
There is the function of doping weakened the noise suppression, can effectively reduce back the noise.
Receiver using multilevel high frequency amplifier, has a very high sensitivity.
Multiple noise monitoring circuit, AD hoc mono locking TONE - LOCK system, make it has the incomparable anti-interference characteristics.
Use good chip and parts with high quality, make the machine quality is very good.
Open the maximum range of 100 meters above, ideal open using range of 50 meters.
