Fast Suppression, Minimal Damage
DF-1 targets narrow problem zones instead of broad cuts, so vocals and instruments keep their character.

Kill Feedback Before It Kills The Show
De-Feed DF-1 is a professional feedback suppressor built for the pressure of real stages. It listens in real time, finds ringing frequencies quickly, and applies narrow suppression so your mix stays loud, clear, and in control.

Engineered for Live Pressure
Live rooms are unstable by nature: microphones move, wedges shift, players change position, and gain rides happen in real time. DF-1 is built to react like an engineer who never blinks, without flattening your mix or gutting your tone.
Built for Real Sessions
Designed to be practical and low-overhead in DAWs and live rigs where reliability matters more than hype.
Control You Can Trust
Set it and run, or dial deeply by hand. DF-1 supports both fast workflows and engineer-level precision.
Fast Control. Real Results.
DF-1 gives you controls that matter in high-stakes moments. No bloat, no guesswork. Just direct parameters that shape detection behavior and suppression feel.
Core Controls
- Threshold - Set detection sensitivity
- Notch Depth - Set suppression strength per notch
- Speed - Control engagement timing
- Release - Shape recovery behavior
- Bypass - Hard bypass when needed
What You Get
- Up to 8 notch slots for focused correction
- Automatic response to detected ringing
- Adaptive tracking for drifting frequencies
- Output limiter for safer stage output
- Mono-safe processing for live and studio use
- Mono-to-Stereo-safe processing for live and studio use
- Stereo-safe processing for live and studio use

Precision DSP, Not Guesswork
Under the hood, DF-1 combines a lightweight detector, an 8-slot notch bank, and a safety output stage. In plain terms: it hears the problem, identifies the frequency, and removes just enough to keep the show alive.

Three Modes. One Mission.
Whether you want automated defense or full manual authority, DF-1 gives you a mode that matches your workflow.
DF-1 listens, detects, and engages notches automatically. Great for fast setup and immediate protection.
You activate and tune notches directly. Ideal for detailed scenes and repeatable engineering decisions.
Notches can track slow frequency drift so suppression stays locked even when stage conditions move.
For Engineers Who Want More Gain, Not More Risk
DF-1 is made for FOH engineers, monitor engineers, performers, and creators who cannot afford feedback chaos. If your work happens in real time, DF-1 is built for your reality.
FOH Engineers
Push vocal clarity and stage level with more confidence, fewer emergency fader drops.
Monitor Engineers
Fight spill and hotspots while preserving performer comfort and intelligibility.
Artists and Creators
Run rehearsals, streams, and hybrid rigs with cleaner output and fewer sudden surprises.
Make Feedback Someone Else's Problem
You have a room to manage and a performance to protect. Let DF-1 handle the ringing before the audience hears it. More confidence. More usable gain. Fewer disasters.
