First, environmental noise reduction: noise reduction NS<=15DB, so that no environmental noise can be heard by human ears.
Second, steady state noise reduction: air conditioning noise, fan noise and other noises 50cm away from the microphone can be completely filtered out. Noise reduction<=15DB.
Third, call level full duplex: In any conference call scenario, both parties speak at the same time, and neither party will get stuck, ensuring the comfort and fluency of the call.
Fourth, ultra long distance pickup: the pickup distance radius can reach 3m.
Fifth, automatic tracking: the machine is equipped with 4 digital microphones, 360 degree pickup. The adaptive focusing algorithm can be adjusted intelligently according to the position of the sound source to ensure the high fidelity of the sound.
Sixth, automatic gain: ensure that the collected sound is consistent within a 5m radius.
Seventh, echo cancellation "On the premise of ensuring the smoothness and comfort of the call, eliminate the sound played by the speakers to make the call more smooth and comfortable. AEC<=50 DB,<=400MS
Eighth, sound expansion: the equipment is reserved with an external AUX interface, which can be connected to an external active speaker. On the premise that users need a greater sound effect, the sound played by the speakers can be further expanded.
Ninth, volume synchronization: The device and OS system, Windows system (some Android systems, some Linux systems, some Android phones) can achieve volume synchronization, directly control the system's call volume, and display it on the light guide column at a glance.
Tenth, Type-C interface: Type-C interface is adopted, which is more reliable than traditional Mini B 4Pin, Mini B 5Pin and other connections. It can be plugged and unplugged at will, regardless of direction.
