VISSONIC Audio Link Network PA System Automatic Feedback Suppressor Sound Processors

VISSONIC Audio Link Network PA System Automatic Feedback Suppressor Sound Processors

VIS-FS100-A feedback suppressor uses a powerful signal processor and a fully automatic adaptive algorithm, which is easy to use. In addition to supporting 4-line / microphone input, it is also equipped with an AUDIOLINK digital audio cascade interface and supports 5 channel automatic mixer.

Features

1.Fully automatic high-speed howling suppression algorithm, no need to debug, ready to use

2.Eliminate feedback

3.Automatically adapt to the acoustic environment

4.Up to 12DB additional gain to effectively prevent feedback

5.Equalized line or microphone input to provide phantom power

6.With AUDIOLINK digital cascade input and output interface

7.Four microphone inputs and digital interface AUDIOLINK inputs with automatic mixer
