HP-619 Wireless Microphone System

HP-619

Product Features:

Using ultra-high frequency band: 612.5M-667.25MHz, so that the system has a strong anti-interference ability;
Using PLL phase-locked loop technology, with high-precision quartz crystal and microcontroller, the system maintains extremely high-frequency stability;
With the RDS digital pilot function, each microphone has a different random identification code, which can eliminate interference and crossover frequency to the greatest extent;
Using a self-developed automatic mute and anti-vibration circuit, it can avoid on/off operation noise and noise caused by weak signals;
Using a self-developed dual boost circuit design, the microphone can maintain stable battery performance even at low voltage;
The intelligent operating system is adopted, which makes the interface operation simple and flexible, and can reflect the information on the display screen in real time;
The microphone has high sensitivity and wide frequency response, making your speech or speech easy and comfortable;
The system can be stacked. Stack up to 5 units, no interference, no cross-frequency.
