    Document Conventions The DFR22 software interface is so intuitive and user friendly that you may be tempted to skip reading this document and immediately begin programming the unit. Before you do, however, you should at least skim this overview, then thoroughly...

  • Page 6: Audio Processor Features

    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.

  • Page 7: Dfr22 Software Minimum Requirements

    When you launch the application, you always begin in Design Mode. This is the mode you use to create presets that are later stored in the DFR22. In this mode, it is not necessary for the computer to be connected to the device.

  • Page 8: The Main Window

    The information on the title bar of this window changes depending upon the operating mode. In Design Mode the title bar reads, “DFR22: Offline,” and indicates the default security level. In Live Mode, it displays informa- tion specific to the unit to which you are connected, as illustrated below in Figure 1-2.

    You can perform many of these steps without actually being connected to the device, by saving your presets to the com- puter and transferring them to the hardware at a later time. In order to acquaint you fully with the features of the DFR22, these instructions are written presuming the following conditions: •...

  • Page 13: Configure External Control

    Configure External Control If there are external devices connected to the control pins, you need to configure the DFR22 to recognize the external controllers. This configuration is stored at the device level and should be established before you create any presets. If you are not connected to the device, you can create a configuration and save it on the computer to be later trans- ferred to the DFR22 through the RS-232 connection.

  • Page 14: Create A Preset Template

    1. Select a Preset Template When you start the DFR22 application there is a blank preset in the signal flow diagram. If you would like to use one of the other default presets as a template, select [File>New] from the main menu and then select [Dual Mono], [Stereo], or [Dual Mono Split].

    9. Lock Processors for Read-Only Access This step is applicable only when you are customizing security for end users accessing the DFR22 from the soft- ware. This type of security is stored with each processor, at the preset level. Select the processors that the user should not be able to modify, and select [Security>Level 2>Lock Selected] from the main menu.

  • Page 17: Creating A Preset

    Gain Structure The DFR22 Audio Processor provides gain control at three stages of the signal flow: input gain, matrix mixer, and output gain. It is essential to obtain an understanding of this gain structure before passing audio through the unit, in order to avoid damaging equipment that is in line after the Audio Processor with excessive gain levels.

  • Page 18: Muting Channels

    To change a channel label: Double-click on the channel's gain block. In the processor window, locate the channel's label box. Click and drag over the text to highlight it. © 2003 Shure Incorporated DFR22 Software Guide...

  • Page 19: Signal Routing

    Signal Routing The DFR22 allows you to route signal from either of the two inputs to either or both of the outputs. In order for sig- nal to pass from the input channel strips to the output channel strips, it must be routed through the matrix mixer.

  • Page 20: Naming A Preset

    Naming a Preset Since you can store up to 16 different presets in the DFR22, it can be helpful to differentiate them with a name and a brief description. The information box in the center of the control bar of the main window displays these details, as pictured below in Figure 3-2.

    Processor blocks can be added to an existing link group, if they are the exact same type of processor and they are currently unlinked. Any processor added to a link group will inherit the group's current settings. © 2003 Shure Incorporated DFR22 Software Guide...

  • Page 25: Bypassing

    Processor Block Managing DSP Resources Although the DFR22 has sufficient processing power for many applications, it is possible to populate the signal flow diagram with more processor blocks than the device's DSP (digital signal processing) resources can handle. This section explains in general terms how the Audio Processor manages the signal processing requirements of a configuration, and gives you some hints on how to get the most out of the DSP resources.
  • Page 26 Delay Memory The DFR22 has a memory buffer that will hold up to 10 seconds of delay time, which you can divide among any combination of delay processors. Like DSP resources, delay memory is allocated to each processor block according to the maximum delay time indicated in the block name.

  • Page 27: Default Presets

    Default Presets To help you get started with basic configurations, the DFR22 comes loaded with three default presets. These presets are also listed in the [File>New] sub-menu, so you can use any of them as a template to create a new preset.

  • Page 28: Preset And Device Management

    In Design Mode after you create a preset, you can save it either to the computer, or to the device, depending on whether or not you are connected to the DFR22. At any time, one and only one preset is active in the DFR22. This preset is referred to as the live preset.

  • Page 29: Device Presets

    Device Presets Device Presets The DFR22 can store 16 presets in its device memory. Once presets are stored in the device, they can be renamed, deleted, or backed up as a set. Store a Preset in the Device When you are connected to the device, in Design Mode you can store new presets in the device, or open existing preset files and store them to the device.
