b Power/Reset LED — The green LED indicator duplicates the front panel LED operation (see the “Reset Actuator and LED” section for additional information). c Line 1-4 input connectors — 6-pole 3.5 mm double-stacked captive screw connectors accept balanced or unbalanced mono line level signals. Line inputs provide gain settings to accommodate consumer (-10 dBV) and professional (+4 dBu) operating line level sources.
The digital input port is used to monitor TTL level digital signals. Voltages greater than 2 V indicate a logic “high” signal while voltages less than .8 V indicate a logic “low.” NOTE: These ports are configured via DSP Configurator (see the “Digital input ports” section for additional information).
Operation This section describes the operation of the DMP 44 LC, including: • DMP 44 LC Operation • Front Panel Operation • Rear Panel Operation • DSP Processing/Signal Flow • Processor Blocks • Mix Matrix • Line Output Channels DMP 44 LC Operation The DMP 44 LC does not have physical controls. Configuration and operation are accomplished using a PC running Windows® XP or better and the DSP Configurator software (available on the included disc or at www.extron.
Front Panel Operation CONFIG DMP 44 LC DIGITAL MATRIX PROCESSOR 1 2 Figure 6. DMP 44 LC Front Panel a Power/Reset LED — Green power indicator lights when the DMP 44 LC is operational. b Configuration connector — The USB 2.0 port uses a mini type-B connector to connect to a host computer for control. The DMP 44 LC USB driver must be installed prior to using the port (see the “Install the USB Driver” section for details). The DMP 44 LC appears as a USB peripheral with bi-directional communication.
Firmware Updates The firmware of the DMP 44 LC can be updated through USB or RS-232 connection. The user can obtain new firmware from the Extron website. After obtaining the new firmware, upload it to the unit using the Firmware Loader option in the DSP Configurator program (see the “Software Control” section), or using the Extron standalone Firmware Loader application available on the included disc or at www.extron.com.
Digital Input Ports The three-pin Digital Input port is used to monitor or drive TTL level digital signals. The port consists of three input pins with the fourth pin being used as a ground providing three inputs total. The DSP Configurator software provides a selection of functions to be loaded to the DMP 44 LC (see the “Software Control” section). 1. From the menu bar, click Tools > Configure Digital Inputs to access the Configuration utility. 2. Select the digital input to configure.
3. Select the event or “trigger” to configure the input. 4. Select the action that results when the trigger occurs. 5. Select the group to act upon when the trigger event occurs. 6. Select Apply to accept the changes.
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 connected to the DMP 44 LC via the USB configuration port or the RS-232 port. The DSP Configurator program provides complete control while SIS commands provide more limited control.
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 0.1 dB. Line Output Chain Line output chain elements from left to right are as follows: • Trim (TRIM) — One post-mixer mono gain control per channel with a range of -12 dB to +6 dB. The step resolution is 0.
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 channel gain block provides a mono long-throw fader for gain and attenuation. Range for the control is -18 to +24 dB. Step resolution is 0.1 dB.
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 opens the setup dialog box. Figure 8. Filter Block Dialog Box Additional filters are inserted by opening the filter block dialog box, then selecting a filter type from the drop-down filter selection list.
Figure 9. Filter Dialog Box, Filters Added Within the dialog box, a filter is focused when a filter type is inserted, or is focused by clicking the filter number to the left of the filter selection drop-down list. Note how filter 3 in the figure below is highlighted in yellow, indicating it is the filter in focus. The results of the filter in focus (independent of other filters) shows in the graph as a dotted line of the same color as its filter row when bypassed.
Parametric (Equalizer) Up to three parametric filters can be placed in the filter box at one time. Each may be set to a different frequency creating a 3 band parametric equalizer. The control will boost or cut the center frequency, and by changing the Q value, the range of affected frequencies can be widened or narrowed around the center frequency. In general, the higher the Q, the narrower the affected bandwidth.
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 steepness of the frequency attenuation curve will change. High Pass The high pass filter is the opposite of the low pass filter.
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 selection box. Figure 15. Bass and Treble Shelving The corner frequency of the controls may be selected to 0.1 Hz accuracy.
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.
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.
5. Define the group members. Configuring Bass and Treble Groups 1. From the main DSP Configurator screen, select the Filters block, as shown below.
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 Control Groups from the Tools drop-down menu.
5. Select the Bass or Treble control group. 6. Select the group members. 7. Repeat steps 5 and 6 for the unselected control group (Bass or Treble).
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 the processor menu (see the Insert Compressor option in the “Processor Blocks” section).
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 -80.0 to 0.0 dB in 0.1 dB increments. Default is -30.0 dB. Ratio — The input signal level reduction when compression is engaged. Ratio can be adjusted from 1.0 to 100.0 in 0.1 increments. Default is 2.0:1.
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 higher compression ratio of ∞:1. The ratio is fixed and cannot be changed.
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 processor block is inserted, it is automatically set to Enable Source Mic/Line. All inactive ducking processor blocks have Enable Source Mic/Line unchecked by default. 1 5 2 3 6 4 Figure 16.
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 selector (see the following figure). b Enable source mic/line checkbox When checked, ducking is enabled for the current source and the ducker processor block is lit.
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 enabling an input source to take precedence over all but one other input. In the example below inputs 2 and 3 are set to duck when input 1 has a signal above the ducking threshold.
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‑point for each of the four line outputs.
• 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 mix information). Mix information — A solid teal-colored ball indicates that the mix‑point is unmuted.
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 multiple mix-point dialog boxes are open, the mix-point for the most recently opened dialog box receives the light green focus circle, while previously opened dialog boxes relinquish their focus.
In order to understand how the mix-points work, the following figures provide examples of mixes. In the first example figure below, input audio from mic input 1 is processed and arrives at the mix-point. Double-clicking on the mix-point opens the dialog box. When the Mute button is released (not red) on input 1 of the mix-point, the mix-point turns teal with a light green circle to indicate the open mix‑point dialog box is the focus, and the signal is routed to output 1. Figure 19.
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 line output channels. Controls and processing blocks, identical for each output channel, are described in the following sections.
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 damage. While the limiter is closely related to the compressor, it applies a much higher compression ratio of ∞:1. The ratio is fixed and cannot be changed.
SIS Programming and Control This section describes SIS programming and control of the DMP 44 LC, including: • Connection Options • Command/Response Table for Basic SIS Commands • Special Characters • Command/Response Tables for DSP SIS Commands Connection Options The DMP 44 LC Digital Matrix Processor can be remotely connected via a host computer or other device (such as a control system) attached to the rear panel RS‑232 port or the front panel USB Config port.
USB Port (front panel) The DMP 44 LC has a front panel USB port that can be connected to a host device such as a computer running the HyperTerminal utility, DSP Configurator, or the DataViewer utility. The port makes serial control of the DMP possible. After the connection is established, see “Using the Command/Response Tables” later in this section for SIS programming details. DMP 44 LC-initiated Messages The DMP 44 LC initiates messages under specific conditions. No response is required from the host.
Error Responses When the DMP 44 LC is unable to execute the command, it returns an error response to the host.
X% X^ = Internal temperature Degrees Celsius = Dirty status 0 = RAM has been saved to Flash (OK to power off/reset) 1 = RAM needs to be saved to Flash X& = Unit name A text string of up to 24 characters drawn from the alphabet (A–Z) digits (0–9), minus sign/hyphen (-). No blank or space characters are permitted as part of the name. No distinction is made between upper and lower case. The first character must be an alphabet character. The last character must not be a minus sign/ hyphen.

Command/Response Tables for DSP SIS Commands Many digital signal processor (DSP) functions (gain, mute, and group masters) can be controlled using SIS commands. These commands follow the same general rules as basic SIS commands, but the variables (X/) tend to be more complex. Also, a comprehensive understanding of the audio signal flow is helpful in understanding the commands. The following figure shows the specific DSP processors available for SIS commands.
Command/Response Tables for Audio SIS Commands DSP control commands are an extension to SIS commands. They differ only in their data string and the requirement to send each command with an “Au” suffix.
Special Characters The HTML language reserves certain characters for specific functions. The device will not accept these characters as part of preset names, the device name, passwords, or locally created file names. The DMP 44 LC rejects the following characters: {space (spaces are acceptable for names)} + ~ , colon (:) | \ and ?.
Command ASCII Command (Host to Tuner) Response (Tuner to Host) Additional Description Audio group master commands NOTE: See Group Masters, for more information about audio group masters. A group must have assigned members for these commands to have an effect. For X6^, a positive (+) value is assumed unless a negative (-) value is specified. If entering a X6^ value outside the valid range for the group or outside the soft limits, the DMP 44 responds with an “invalid parameter” (E13) error.
