The Behringer FBQ1000 Feedback Destroyer is the fastest feedback suppressor on the market. With its lightning-quick feedback detection, the FBQ1000 will safeguard you and your audiences from feedback. The "search-and-destroy" algorithm automatically pinpoints up to 24 feedback frequencies per channel, then sets ultra-narrow notch filters to knock out feedback frequencies - leaving the rest of your signal untouched. Auto Mode continuously monitors the mix, resetting programmed filters automatically, while the Manual Mode lets you tweak up to 24 parametric filters for frequency, bandwidth and gain. Exterminate feedback effortlessly with the Behringer FBQ1000 Feedback Destroyer.
