  • UHF band transmission signal, common frequency range: 600MHz, optional frequency range 500/700/800MHz;
    Two channels receive signals, each channel has 200 channels to choose from, each channel steps at 250KHz; Each channel uses 49.75MHz;
    Using stable PLL digital phase-locked loop synthesis technology and intelligent digital circuit, the performance stability of the whole machine is significantly improved;
    Each channel is equipped with a unique ID number to enhance anti-interference function and support multiple simultaneous use (up to 20 receivers and 40 transmitters at the same time);
    · Built-in capacitive microphone core with round head, good sound reduction;
    2 rubber receiving antennas are set on the back of the receiver to enhance the received signal and have a decent appearance;
    The back is equipped with 2 balanced output and 1 mixed unbalanced output, suitable for connecting various external equipment;
    Interoperability among 400 channels, showing humanized high-tech design; (The same launch can be interoperable in tow 2. tow 4. tow eight)
    Flexible gooseneck microphone design, which can be adjusted in all directions at 360 degrees, and the microphone lamp ring indicates the speaking state.
    The power consumption of the microphone is 80mA, and it is powered by 1.5V batteries (2 batteries), which can be used continuously for 8 hours;
    The host and transmitter are equipped with LCD screen to display the working status and other contents
    Use distance: open environment: 80-100 meters complex environment: 50-80 meters
    · Suitable for all kinds of meetings and speaking occasions.
