Audio Processor Features
Audio Processor Features
The DFR22 is a 2-input, 2-output digital audio processor with a software interface and simple front panel controls, which
stores 16 presets. It provides 24-bit conversion, 48khz sampling and a minimum dynamic range of 100dB.
Drag and Drop Software Interface
The computer interface to the Audio Processor mimics the functional block diagrams used in sound system design.
This makes the software incredibly easy to learn, because the interface seems immediately familiar to sound pro-
fessionals. Presets can be built and edited entirely by clicking, dragging, and dropping with the mouse. You can
configure the signal path with any combination of drag and drop signal processors.
Modular Signal Processors
Each signal processing module is encapsulated in a graphic block that you can manipulate with the mouse. After
you place a processor in the signal flow diagram you can access the processor settings by double-clicking on the
block to open its parameter window. Settings can be saved and recalled from the computer, and copied between
similar modules. Processor settings can also be synchronized via the link feature. The DFR22 Audio Processor
includes the following selection of signal processor modules.
External Device Control
After it is installed and programmed with the software interface, end users can control the DFR22 with a computer
or an AMX or Crestron controller. In addition, the control pins on the rear panel can be connected to external hard-
ware, so that the DFR22 will respond to contact closures, potentiometers, and wall-plate switches.
Security
The security feature gives the installer peace of mind that the device cannot be tampered with after it is installed.
User access can be completely restricted so that the user cannot change any settings, or use the front panel con-
trols. They will only be able to view the settings of the current preset from the software interface. End-user control
can also be customized to allow access to certain settings, and not to others.
