With an amazingly fast response time of less than 0.2 seconds, the Behringer FBQ1000 Feedback Destroyer & Parametric EQ can either knock-out feedback with one quick punch or use its parametric EQ to fine-tune your live sound with finesse and sophistication. This sophisticated feedback killer is especially ideal if you play live with in-ear monitors, since it will protect your ears from any hearing damage that would otherwise be caused by a feedback bomb. The FBQ1000 works by using an incredibly fast feedback detection algorithm. It automatically locates up to 12 feedback frequencies per channel. Once intelligently identified, the FBQ1000 slips in ultra-thin FBQ notch filters to counteract the feedback frequencies. Some of these filters are as narrow as 1/60th of an octave. This leaves the rest of the frequencies virtually untouched and unaffected. The FBQ1000 comes equipped with a parametric EQ, as well as several different modes. You can use the Set-and-Forget Mode, which is the default setting and is designed to automatically get your Feedback Destroyer up and running in seconds. There's also an Auto Mode that continuously monitors the mix for feedback frequencies. This mode allows the device to reset programmed filters automatically as hints of feedback are developing at other frequencies. Plus, you can just relax and play, talk or jam freely. For a more involved and specialized approach, the FBQ1000 has a Manual Mode as well. This mode lets you program up to 24 fully parametric filters to optimize your sound to the room's acoustics. For enhanced control, each FBQ filter features frequency, bandwidth and gain controls.
