Description
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 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.
