Control System
The Control system brings users a more intuitive operating experience and a more intelligent audio processor experience. The clients supports Windows and Android system, Supports Browser-side controlmethods,and is fully compatible with IE,Chrome, and Firefox.
AFC, AEC, ANS
Automatic Feedback Canceler: Used to eliminate the whistling generated between the microphone and speakers in the sound reinforcement system, thus capturing the frequency that causes the whistling for attenuation to ensure the quality of the sound as well as to prevent burning out of the amplifier or speakers.
Automatic Echo Canceler: Set the signal that needs to be processed by the Echo Canceler, and the processed signal selects the output channel in the Mixer;
Automatic Noise Canceler: Select the signal that needs noise cancellation processing, and the processed signal is output in the mixer by selecting the corresponding channel;
Matrix Mixer
