Bosch LBB1968/00-US Plena Feedback Suppressor None

The LBB1968-00-US from Bosch is a can greatly reduce the risk of acoustic feedback when using a PA system. It does this by using a powerful DSP with a patented algorithm. The unit actively filters out unwanted room reverberations with an echo-cancellation feature and dereverberation algorithm. The device can add a little inaudible noise or shift the output frequency by five hertz. By doing this, it's able to detect the reverb component of the signal and remove it before feedback occurs - leaving the original signal intact. The Plena Feedback Suppressor also features an adaptive filter, which can be switched between fast and accurate modes. The fast mode is ideal for situations where the microphone is changing positions over time, while the accurate mode is ideal for situations where the
