Vissonic VIS-FS100-A automatic feedback suppressor

The Vissonic VIS-FS100-A Automatic Feedback Suppressor is a professional audio processing device engineered to eliminate unwanted acoustic feedback and improve sound clarity in live sound, conference, lecture, and public address environments. Powered by a robust DSP and a fully automatic adaptive feedback suppression algorithm, it continuously monitors incoming signals and suppresses feedback before it occurs — helping you maintain clear, natural audio without manual tuning.

Featuring support for four microphone or line inputs and an AUDIOLINK digital cascade interface, the VIS-FS100-A includes an integrated automatic mixer that intelligently balances multiple mic sources for consistent, intelligible sound. The adaptive filter can switch between “Fast” and “Precise” modes to suit dynamic microphone movement or stable acoustic conditions. With up to 12 dB of additional gain before feedback, this unit increases system headroom and reduces the need for manual EQ in difficult acoustic spaces.

Whether used in meeting rooms, houses of worship, educational facilities, or live events, the VIS-FS100-A enhances speech intelligibility and overall audio performance while simplifying setup and operation.
