  • 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);
    14mm diameter microphone core, wider frequency response and good sound reduction;
    2 rubber receiving antennas are arranged on the back of the receiver, which is perfectly matched with multiple sets of antenna distribution system;
    The back is equipped with 2 balanced outputs and 1 mixed unbalanced output to meet the external equipment;
    The 400 channels of the transmitter are interoperable, showing humanized high-tech design; (The same launch can be interoperable in towing 2., towing 4. and towing eight)
    The mainstream square tube can be adjusted up and down to match the table height and the user's height, which is in line with human mechanics;
    The host is equipped with a lock screen function to prevent misoperation from affecting the meeting;
    The host has the function of monitoring the transmitted signal and power;
    The host and transmitter are equipped with LCD screen to display the working status and other contents
    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;
    Use distance: open environment: 80-100 meters complex environment: 50-80 meters
    · Suitable for all kinds of meetings and speaking occasions.
