DSP Processing and Signal Flow The diagram below shows the signal flow and DSP processing per signal chain. Signal chains and the matrix are described in the following sections. All signal routing, processing, and level control (gain/trim/volume), are accomplished using software control from a PC co...

Mix Matrix The line input process routes incoming signals through a mix matrix to the line outputs. The mix matrix contains 16 mix-points, one for each input to each output bus with each mix-point containing a single fader with a range of -24 dB to +12 dB, plus a mute control. The step resolution is...

Line Input Channels There are four (4) mono line input channels. Channel controls and processing blocks described in the following sections are identical for each of the four inputs. Line (Input) Gain Line inputs provide gain settings to accommodate consumer and pro line level sources. Each input ch...

Filter Block Each line input channel filter block allows a total of five filters. The first filter is inserted from a processor list that appears when the block is double-clicked or via a context window/processor list when the block is right-clicked. After the processor is inserted, double-clicking ...

The parametric filter allows frequency selection accurate to 0.1 Hz and either 6 or 12 dB of slope. Notice at the specified frequency (100 Hz) the signal is 3 dB down, typical operation for high pass filters. The 3 dB down point will remain constant regardless of the slope setting. Only the steepnes...

Bass and Treble Shelving Bass and treble shelving may be added to the filter, as shown below. Adding this filter automatically inserts both bass and treble controls in the dialog box. If only a bass or only a treble filter is required, either bypass the unneeded control or set it to unused in the se...

2. Specify bass and treble filters if necessary. Configuring Groups 1. From the View menu, select Group Controls . 2. To add a new group, select Add a Group . DMP 44 LC • Operation 22

3. Select a group to configure. NOTE: To configure Bass and Treble groups, see “ Configuring Bass and Treble Groups .” 4. Select a control type for the group. DMP 44 LC • Operation 23

2. From the drop down menu select Bass & Treble Filters . 3. Double-clicking the Filters processor opens the configuration screen. Configure the bass and treble parameters. NOTE: The Bypass button is red when the filter is bypassed or not active. 4. To configure a control group member, select Co...

Dynamics Processor A dynamics processor alters the dynamic range, the difference between the loudest to the quietest portions of an audio signal. Each input channel offers one dynamics processor block that, when inserted, provides a compressor. To insert a processor into an empty block, select from ...

Compression can also be used to protect a system or a signal chain from overload similar to a limiter. Threshold — The input signal level above which compression begins (subject to attack time) and below which compression stops (subject to hold and release time). Threshold level can be adjusted from...

Limiter The limiter restricts the input signal level by compressing its dynamic range above a specified threshold. The limiter is most commonly used to prevent clipping, protecting a system against component or speaker damage. While the limiter is closely related to the compressor, it applies a much...

Ducking is configured in a window which opens when an active ducking processor block is double-clicked (see the following diagram). Ducking can be globally set up from a single configuration window, which opens when any of the active ducking processor blocks are double-clicked. When a ducking proces...

Ducking Configuration Dialog a Current source indicator Shows the selected input. Ducker settings affect the input channel shown here. When a ducker dialog is opened for a channel, the current source defaults to that channel. The current source can also be selected via the priority readout/source se...

f By (dB) Individual attenuation settings for each duck target in dB. The default is 20.0 dB. If additional attenuation of the targets is required, increase this value. The attenuation range is 80.0 to 0.0 dB in 0.1 dB increments. Priority In some cases, multiple levels of ducking may be required en...

Mix Matrix The DSP architecture contains a mix matrix that connects the line inputs to the line outputs. The DSP Configurator GUI provides control of the mix matrix, used to set mix levels from the post processing inputs, to each line output bus. Each of the four line inputs is connected to a mix-po...

• OK/Cancel — Click OK to accept changes and close the window. Cancel ignores changes and closes the window. The title above the fader reflects the output channel name for the mix-point. Mix-point GUI behavior: No mix information — A solid gray ball indicates thst the mix-point is muted (contains no...

Double-click — Double-click to open the mix-point dialog box. The focus circle turns light green in color to indicate the open dialog box, as show in the following figure. If the mix-point is muted, the mix-point ball will be gray. If unmuted, the ball will be teal. Multiple open dialog boxes — When...

In the example figure below, inputs 1 to 4 have been routed to outputs 1 through 4 by unmuting the mix-point for mic/line input 1 on each output (1 through 4) bus. Again, the mix-points are teal to indicate the routing. Figure 21. All Inputs to All Outputs Line Output Channels There are four mono li...

Dynamics The output channel dynamics block provides a limiter function (see the diagram below) that restricts the input signal level by compressing its dynamic range above a specified threshold. The limiter is most commonly used to prevent clipping, protecting a system against component or speaker d...
