[. . . ] It's much more than feedback reduction. For many jobs, it's the only audio processor you'll need. Flexible. Configurable. Processing blocks in the DFR22 can be applied in any order, to any input or output. You can also link processors for more efficient global control. Copy and paste processing blocks to any input or output to duplicate processors across multiple channels. The Shure DFR Difference. Featuring enhancements to Shure's patented Adaptive Notch Filter Algorithm, the DFR22 includes single-channel and stereo processing blocks with up to 16 precision notch filters that automatically seek out and reduce feedback. With widths between 1/10 and 1/70 of an octave, these adaptive filters affect only the problem frequencies, maximizing system stability and sound integrity. In addition, Auto Clear mode removes dynamic filters and restores the DFR to your ideally-tuned configuration after a specified amount of time. 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. [. . . ] How DFR22 Functions as a Monitor Processor. [. . . ]
