Digital Feedback Reduction for SCM820: A Video

A new addition to the SCM820 control software, the DFR (Digital Feedback Reduction) function adds two channels of adaptive EQ filtering to find and remove feedback frequencies, which noticeably improves gain before feedback in live sound reinforcement systems.

Check out this short video walk-through of the software interface that allows you to set up the DFR function for the SCM820 8-Channel Digital IntelliMix® Automatic Mixer.

DFR features are supported in SCM820 firmware version 1.1.X or higher. Previous versions (1.0.11 and earlier) will require a firmware update.
