The Plena Feedback Suppressor is an easy to use and ideal solution for applications like houses of worship and congress centres where microphone and loudspeakers are often in the same room and the annoying effect of feedback can occur.

A high-power floating point DSP is used with a revolutionary patented algorithm to suppress acoustic feedback already before it occurs, even within difficult acoustical environments.

A smart combination of adaptive filtering, signal decorrelation and dynamic echo suppression filters out the sound from the loudspeakers that reach the microphone again, while passing the sound from the original source. This process is continuous and completely automatic, so no difficult notch filters have to be set. Just switch on the unit and experience how much louder the volume can be set compared to the original (bypass) situation. Sounds like magic.

The unit also has 2 microphone inputs with builtin auto-mixer, that adjusts both inputs in such a way that the microphone that is spoken in loudest gets the highest gain, while keeping the summed gain constant for maximum feedback margin. This is ideal for a dual microphone set-up on a rostrum, pulpit or conference table.
