The FBQ2496 is an incredibly fast feedback suppressor because it uses a speedy feedback detection algorithm that automatically and intelligently locates up to 20 feedback frequencies per channel. It then sets an extremely narrow notch filter to eliminate them, leaving the remainder of the signal virtually untouched. The auto mode continuously monitors the mix, resetting programmed filters automatically, while the manual mode allows individual settings of up to 40 fully parametric filters with frequency, bandwidth, and gain adjustment. With its various modes you can master just about any live sound situation, or use the Feedback Destroyer Pro as a creative sound-shaping tool. Type: Sound and Recording
