Stop ringing feedback before it ruins the show. The Behringer DF1000 is a dedicated feedback destroyer that listens to your live signal, finds problem frequencies in real time, and notches them out automatically — so vocals stay clear, monitors stay loud, and your audience hears the music, not the squeal.

Built for live sound engineers and working bands

• Automatic feedback detection identifies and eliminates resonant frequencies before they take over the room.
• Precision narrow-band filters remove only the offending frequency — your tone stays intact.
• Fast-acting response catches feedback at the first hint, not after it's already squealing.
• Manual mode for tuning out known room nodes during soundcheck.
• Studio-grade signal path keeps your sound transparent when no feedback is present.
• Rack-friendly format slots straight into your live rig.

From house-of-worship platforms to club PA racks, the DF1000 buys back the headroom you've been afraid to use — and gives every performer the confidence to lean into the mic.
