Shure DFR22 Feedback Suppression Processor - Black

An excellent stereo DSP.

The DFR22 is a rock-solid two-channel DSP with many drag-and-drop processing features. The only drawback is the serial programming interface. (Shure recommends the FTDI US232R USB to RS232 adapter and it works great!)Read full review

DFR22 Still a good choice

This item was used but it works just like a new one. The only drawback with a DFR22 is having to use RS232 to program it but that was common when this was designed.
