FBQ 2496

The FBQ2496 is the fastest (>0.2 sec.) and the only 96kHz feedback suppressor on the market. Using an ultra-fast feedback detection algorithm, it automatically and 'intelligently' locates up to 20 feedback frequencies per channel and sets extremely narrow notch filters to 'destroy' them, leaving the remainder of the signal virtually untouched.
