AFS333 Fully Automatic Feedback Suppressor

AFS333 Fully Automatic Feedback Suppressor

Suppress the howling which is caused by acoustic feedback in the sound system.

The adaptive filter can be switched between “fast” mode and “precise” mode;

The fast mode is suitable for occasions where the position of the microphone changes frequently;

The precise mode is suitable for occasions where the microphone position is fixed;

The adaptive filter can converge at a slower speed, thereby effectively suppressing more reflection components

描述

Introduction.

►Suppress the howling which is caused by acoustic feedback in the sound system

►The adaptive filter can be switched between “fast” mode and “precise” mode.

►The fast mode is suitable for occasions where the position of the microphone changes frequently, such as in a conference system equipped with multiple microphones and switched between them.

►The precise mode is suitable for occasions where the microphone position is fixed, for example, a forum where the acoustic environment is relatively stable.

►The adaptive filter can converge at a slower speed, thereby effectively suppressing more reflection components

►Before acoustic feedback occurs, an additional gain of up to 12dB can be obtained, depending on the acoustic environment and the selected operating mode.
