Behringer FeedBack Destroyer Pro

Using an ultra-fast feedback detection algorithm, the FBQ2496 automatically and ÒintelligentlyÓ locates up to 20 feedback frequencies per channel. The algorithm then sets extremely narrow notch filters (up to 1/60th of an octave) to ÒdestroyÓ feedback frequencies, leaving the remainder of your signal virtually untouched. And with the ÒSet-and-ForgetÓ default setting, plus the Panic button, your FEEDBACK DESTROYER can be up and running in a matter of seconds.
