DFR22 Audio Processor
The Industry Standard for Effective Feedback Reduction

"Our pastor can walk anywhere in the room and we don’t worry about feedback or reducing levels."
- Jim Weveiris, Bayside Chapel, Barnegat, NJ

Two Channels. A Powerful Processor. The DFR22 delivers an affordable full-featured 2x2 audio processor with Shure's drag-and-drop software. It's much more than feedback reduction - for many jobs, it's the only audio processor you'll need.

The Shure DFR Difference. The DFR22 includes single-channel and stereo processing blocks with up to 16 precision notch filters that automatically seek out and reduce feedback. In addition, Auto Clear mode removes dynamic filters and restores the DFR to your ideally-tuned configuration after a specified amount of time.

Easy Setup and Real Time Visual Monitoring. With the DFR22, you can design the entire system, save it to disk, and load it at the job site for easy setup. The DFR22 also allows real-time design changes, so you can add, subtract, or change processing blocks as you tune the system. Frequency response and signal levels can be visually monitored in real time as parameters are adjusted.

You get the best possible customized processor for your application.
