Behringer FBQ2496 Feedback Destroyer Pro - FEEDBACK SUPPRESSOR AND PARAMETRIC EQUALIZER

(This text is machine translated) The FBQ2496 Feedback Destroyer is the fastest feedback suppressor on the market with a response time of less than 0.2 seconds. It uses a very fast feedback detection algorithm that detects up to 20 frequencies per channel automatically and "intelligently" and sets up extremely tight notch filters to destroy them while leaving the rest of the signal virtually intact.
