FEEDBACK DESTROYER PRO FBQ2496 User Manual 1. Introduction The FBQ2496 is the fastest (>0.2 sec.) and the only 96 kHz Feedback Suppressor in this market price segment. 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.

Connectivity Options 5.2 FBQ2496 in channel insert ◊ The FEEDBACK DESTROYER PRO is not intended to be connected directly Since you want to make sure that deliberately produced feedback signals, such as “guitar feedback,” are not eliminated, try inserting the FBQ2496 into those channels that are susceptible to feedback.
