This is the FBQ2496 Feedback Destroyer PRO.
The FBQ2496 Feedback Destroyer PRO is the fastest feedback suppressor on the market (less than 0.2 seconds) and the only one to off er a 96 kHz sampling rate. This rack-mountable audio solution is the quick, easy way to protect yourself and your audience from feedback.
Using an ultra-fast feedback detection algorithm, the FBQ2496 automatically and “intelligently” locates up to 20 feedback frequencies per channel. The algorithm then sets extremely narrow notch filters (up to 1/60th of an octave) to “destroy” feedback frequencies, leaving the remainder of your signal virtually untouched. And with the “Set-and-Forget” default setting, plus the Panic button, your FEEDBACK DESTROYER can be up and running in a matter of seconds.
Auto mode continuously monitors the mix, resetting programmed filters automatically, while the Manual Mode allows individual programming of up to 40 fully-parametric filters with frequency, bandwidth and gain adjustment. Open MIDI architecture makes future firmware updates and flexible communication with digital equipment exceedingly simple.
