©2003 Shure Incorporated Page 1 of 2 Printed in U.S.A TL1061 (CE) Specification Sheet DFR22 AUDIO PROCESSOR The DFR22 is a full-featured 2x2 audio processor featuring Shure's patented automatic feedback reduction. It also includes equalization, dynamics processing, delay, matrix mixing, and a 2-way crossover. It is configurable using Shure's intuitive drag-and-drop software inter- face. It also functions as an out-of-the-box two channel feedback reducer that does not require a computer for configuration. DESCRIPTION SOFTWARE FEATURES The primary interface for the DFR22 is a Windows-based software program that mimics the functional block diagrams used in sound sys- tem design. Unlike many other DSP products that constrict freedom with preset templates, the processing blocks in the DFR22 can be applied in any order, to any input or output. Processing blocks can be copied and pasted to duplicate processors across multiple chan- nels. They can also be linked for more efficient stereo or global control. With the DFR22, the entire system can be designed, saved to disk, and loaded at the job site for easy set up. The DFR22 also allows real-time design changes, so processing blocks can be added, removed or changed during system tuning. The security options allow complete lock of the system to prevent undesired tampering or to restrict user access to certain parts of the system. Control input pins allow connection of potentiometers, contact closures, and Shure's DRS10 for remote control of preset changes, volume, and muting.
