Bosch Plena - Feedback Suppressor

• Patented feedback suppression algorithm


• Suppresses feedback before it occurs


• Automatically adapts to the acoustical situation


• Up to 12 dB additional gain before feedback occurs

The Plena Feedback Suppressor uses a powerful DSP with a revolutionary algorithm to suppress acoustic feedback. It eliminates feedback by actively filtering out the unwanted room reverberation using an echo-cancellation and de-reverberation algorithm. By adding masked (inaudible) noise to the output signal or by shifting the frequency of the output signal by 5Hz, the Plena Feedback Suppressor is able to detect the reverberation component of the signal and remove it before feedback occurs, leaving the original signal intact.
