* 1 short-circuit signal input, can be connected to the linkage trigger signal, in case of emergency can trigger the terminal alarm;
* 1 short-distance signal output, in case of emergency can be linked to trigger other equipment;
* The 2.4G microphone transmits a long distance and can transmit audio data steadily within an open area greater than 20 meters after successful connection;
* 2.4G plus automatic search for channel pairing with less interference, complete automatic pairing, to ensure that the product is not serial frequency, strong anti-jamming and transmission stability;
* Expanded a number of 2.5G channels, effectively avoid WIFI / Bluetooth and other 2.4G signal interference;
* 64kHz/16bit sampling rate to meet high-quality audio transmission requirements;
* The two automatic anti-screaming algorithms of mobile frequency/sink wave are used to effectively suppress the whistling sound while ensuring the distance of pick-up;
* Built-in true reverb function, effectively improve the sound quality of speech, so that speech is dry, not hard, reverb level can be adjusted;
* Supports one-click mute function, after mute AUX (3.5 audio input interface) can still transmit audio normally;
* Supports built-in microphones and external microphones, which can be configured with a headset microphone or a collar microphone;
* Support AUX audio input, the use of the global universal 3.5mm interface, the creation of a body audio signal wireless transmission;
* Support laser pen whip, automatic PD control technology, to prevent excessive laser power caused by safety accidents. It is strictly forbidden to shine on the eyes;
* Support PPT page turning: PPT page turning module support hot-swap, no need to drive software;
* The base charging design, user-friendly design, built-in strong magnetic close to the automatic suction to ensure good charging contact, while supporting MICRO USB charging;
* LIQUID CRYSTAL DISPLAY, DISPLAY CONNECTION STATUS, CHARGE (CHARGE DISPLAY), VOLUME, PPT FUNCTION, ETC.;
* All settings have automatic memory function of power-down, personalized settings are more convenient to use;
* Automatic audio energy detection, detected no speech or audio input, the module can output control signal control amplifier mute;
* With power-saving mode, when the device is turned on without connection, without keys 5 minutes automatically shut down;
* Small size, ultra-low power consumption design, Chinese/English menu display;
