Key Features
360°Omnidirectional Far-Field Pickup
Captures clear speech from all directions across an expansive 10-meter (33 ft) radius, ensuring every speaker in the room is heard.
Smart Adaptive Gain Control (AGC)
Automatically adjusts microphone volume in real time based on the speaker’s distance and speaking level within the 10-meter range—delivering consistently balanced and comfortable audio levels.
Automatic Echo Cancellation (AEC)
On the premise of ensuring smooth and comfortable communication.eliminate the sound played by the speaker to make the call smooth and comfortable
Enhanced Voice Clarity (Noise Reduction)
Intelligent voice enhancement technology suppresses ambient background noise while boosting speech clarity for crisp, intelligible dialogue.
