characteristic:
● The effective distance is 30 meters, and 10 sets can be used at the same time
● PLL frequency synthesis phase-locked loop technology is applied, with adjustable frequency and transmission power to avoid frequency interference.
● The bus control of the integrated central processing unit CPU, combined with the digital LCD interface display, is easy to operate and has excellent performance.
● Audio compression expansion technology is adopted to greatly reduce noise and increase dynamic range.
● It is equipped with the function of reinjection howling suppression and attenuation, which can effectively reduce reinjection howling.
● The receiver adopts multi-level high-frequency amplification, and is equipped with high-quality capacitive pickup. The system has extremely high sensitivity.
● Diversity technology;
● 100 channels are adjustable, and multiple sets can be used simultaneously without interference;
● The panel can set the working distance, display mode and panel lock function
● Electronic monitoring, electronic volume
