| Function parameter ● Use FM frequency modulation to realize sound signal transmission, high fidelity, high signal-to-noise ratio, and no sound delay. The unique new-type anti-howling anti-single-point high-sensitivity capacitor microphone makes the conference sound almost perfect. ● The audio channel and control channel are transmitted wirelessly, no cables need to be laid, and the signal coverage can be moved arbitrarily in the park, making the venue layout convenient and flexible. ● Independently developed data communication algorithms for conferences, so that within the signal range, the system response speed is not affected by the number of attending units. Users can flexibly increase or decrease the presence units. The factory default system attendance unit capacity is ≦ 255 (including 1 chairman). ● It has multiple conference speaking modes of rotation 1-2-3-4, restriction 1-2-3-4, and chairperson's exclusive. The main control machine can be connected to the video host to realize the video tracking function of the attendance unit at the venue. ● Ultra-low power consumption, continuous speaking time of more than 8 hours and standby time of more than 20 hours; the 5th ordinary battery or the manufacturer's original lithium battery can be used. The matching charging box has an intelligent charging management circuit, which effectively protects the battery, extends the battery life and ensures safety. ● Large screen LCD display. Hierarchical menu design makes operation simple and convenient. And there are many functions such as power display and under voltage warning, frequency channel and signal indication. ● The main control engineer adopts an all-metal structure design, which is solemn and generous; the attending unit is made of engineering plastic material with a novel appearance design and built-in antenna, which is beautiful and decent. Technical Parameters System audio frequency response: 50Hz ~ 16KHz; System signal-to-noise ratio:>85dB Working voltage: DC12V Can be installed in a 19-inch standard cabinet |
