1.Build-in 1200 frequency point 2.High Anti-interference 3.Twin channel PLL designing 4.IR frequency selection

    J-92U UHF Professional High Band Wireless Microphone

The advantage and feature for this upgrade is as below:

Transmitter: 

* Four-layer circuitboard: High frequency signal anti-jamming, shielding

* Local oscillator: VOC: Solve the high and low end volume balance

 

Receiver:

* Digital pilot: to prevent the same frequency, adjacent channel interference

* Unique ID technology: the digital sender pilot

* Multi-level control: static microphone, field strength, CPU control

* Built-in 1200 frequency points, 60 modules (60 rooms)
