BOSCH LBB1968/00 Plena Feedback Suppressor

The Plena feedback suppressor uses a powerful DSP with a patented algorithm to suppress acoustic feedback.

It actively filters out unwanted room reverberations using an echo-cancellation and dereverberation algorithm. By adding masked (inaudible) noise to the output signal or by shifting the frequency of the output signal by five hertz, the Plena feedback

suppressor is able to detect the reverb component of the signal and remove it before feedback occurs. This leaves the original signal intact.
