Product Description
The Shure DFR has quickly become the industry standard for effective feedback reduction. The DFR22 builds on that reputation to provide an affordable full-featured 2x2 audio processor with drag-and-drop software.
The DFR22 is ideal for installed sound reinforcement applications, such as houses of worship, theaters, and meeting facilities.
DFR22 is also a powerful setup tool in live music applications. Using the DFR22’s drag-and-drop graphical user interface, processors can be placed anywhere in the signal path.
