  • Product Features
  • Product Parameters
  • 1. New audio circuit architecture, true diversity microphone;
    2. Automatic search interference-free channel function, more convenient installation;
    3. The maximum output volume can be freely limited, adapt to a wider range;
    4.UHF band, phase-locked loop (PLL) frequency synthesis;
    5.100x 2 value channels, channel interval 250KHz;
    6. True diversity superheterodyne secondary frequency conversion design, with high receiving sensitivity;
    7. The radio frequency part adopts multi-stage high-performance medium traveling wave device, with excellent anti-interference ability;
    8. The first intermediate frequency uses acoustic resonator filter, and the second intermediate frequency uses three-stage ceramic filter, which improves the anti-interference ability;
    9. The microphone uses Tesco's No. 5 battery, and the continuation time is 8-12 hours;
    10. The microphone adopts a unique boost design, and the battery power drop will not affect the overall performance of the microphone;
