●FM frequency modulation is used to realize sound signal transmission, high fidelity, high signal-to-noise ratio, and no sound delay.

●The use of a new type of anti-howling unidirectional high-sensitivity capacitor microphone core to make the conference sound good.

●The audio channel and control channel are transmitted wirelessly, without laying cables, and the signal coverage can be moved arbitrarily in the park, making the layout of the venue convenient and flexible.

●Independently developed data communication algorithm for conference applications, so that the response speed of the system within the signal range is not affected by the number of scenes of the attendance unit. Users can flexibly add or remove attendance units.

●The factory default system attendance unit capacity is ≤255 (including 1 chair). I has a rotation 1-2-3-4, limit 1-2-3-4, the chairman's exclusive multiple conference speech modes, the main control machine can be connected to the external video host, to realize the video tracking function of the venue attendance unit.

●Ultra-low power consumption, more than 8 hours of continuous speaking time and more than 20 hours of standby time in the attendance unit; No. 5 ordinary batteries or the manufacturer's original lithium batteries can be used.

●The supporting charging case has an intelligent charging management circuit, which effectively protects the battery, prolongs the battery life and ensures safety.

● Large screen LCD display. The hierarchical menu design makes the operation simple and convenient. There are many functions such as power level display and undervoltage warning, frequency channel and signal indication.
