About This Guide

This guide contains installation, configuration, and operating information for the Extron DMP 44 LC Digital Matrix Processor, software controlled digital audio processor. In this guide, the terms “DMP 44 LC,” “DMP,” and “device” are used interchangeably to refer to this product.

About the DMP 44 LC Digital Matrix Processor

The DMP 44 LC Digital Matrix Processor is a compact, standalone audio mixer with four line inputs and four line outputs. It features a digital signal processing platform for audio signal routing and control, and offers several audio digital signal processing (DSP) tools for mixing, routing, and room optimization. Using high-quality 24-bit A/D converters sampling at 48 kHz, input signals are converted into the digital domain where digital signal processing algorithms process and mix the signals. A matrix mixer provides flexible architecture that allows for versatile processing, mixing, and routing scenarios.

The DMP 44 LC has no front panel controls. All configuration of DSP processors and the matrix mixer is performed using the Extron DSP Configurator program from a host computer via RS-232 or USB communication ports. Three digital input ports permit connection of switches and sensors to provide input to the system for triggering a variety of actions within the device.

Two operational modes, live and emulate, allow for working offline from the DMP to set up a configuration and create presets and group controls as needed before loading the configuration to the processor. DSP Configurator settings developed offline can be saved to the disk as a job file that can be uploaded to the device at a later time, or can be transferred directly to the device by switching to live mode. Up to 16 full or partial presets and up to 16 group master controls can be created and stored on the DMP. Control systems connected to the DMP 44 LC by RS-232 or USB can control a subset of device functions using Extron Simple Instruction Set (SIS) commands.

Features

- Consumer and professional audio compatibility — Line inputs provide gain settings to accommodate consumer (-10 dBV) and professional (+4 dBu) operating line level sources.

- Inputs — Four balanced or unbalanced line inputs on 3.5 mm, 6-pole captive screw connectors.

- Outputs — Four balanced or unbalanced line outputs on 3.5 mm, 6-pole captive screw connectors.

- 4x4 line level audio matrix mixer — The DMP 44 LC is a compact matrix processor with DSP. Four line level inputs can be processed, mixed, and routed to four line level outputs.

- DSP audio signal processing — DSP is provided on all input and output paths.

- 24-bit/48 kHz analog-to-digital and digital-to-analog converters — High performance converters preserve audio signal integrity in input and output signal conversion while maintaining latency under 1 ms.

- Digital input ports — Three configurable digital input ports are provided to connect external switches and sensors to the mixer for remote triggering of functions within the DMP 44 LC.

- Building blocks processor templates — A collection of pre-designed processor templates optimized for a specific type of input or output device, such as microphones and Extron speakers, with preset levels, filters, dynamics, and more. Flexible building blocks are available on each I/O strip to allow system designers to fully customize and save their own building blocks, further streamlining audio system design and integration.

- Console View — An optional view within the DSP Configurator software allows system designers to see all gain settings and routing, along with live metering in a single window. Console view provides overload indication, numeric values for levels, and mute status for each input, gain stage, mix-point, and output, so that settings between inputs and outputs can be easily compared and adjusted in one view.

- Live and emulate operation modes with configuration file saving — Allows settings to be configured offline, then uploaded to the DMP 44 LC. The software also backs up configurations from the device for archiving.

- Low latency DSP processing — The DSP engine supports an array of concurrent audio processing within an audio channel and across multiple channels while maintaining extremely low latency from input to output.

- DSP Configurator Software — The PC-based software tool enables management of all DMP audio operations. It enables complete setup and configuration of digital audio processing tools, as well as routing and mixing.

- Intuitive Graphical User Environment — The DSP Configurator software features a graphical user environment with a clear view of all input and outputs, audio processing blocks, routing, mix-points, and virtual routing in a single window. This allows a designer or installer to quickly view all audio activities without having to access multiple windows or menus.

- SpeedNav keyboard navigation — SpeedNav enables user-friendly, keyboard-based navigation of the DSP Configurator software without the need for a mouse or touchpad. Using keyboard navigation keys and shortcuts, a user can access any input or output, mixing points, and all audio DSP tools. Using only the keyboard for software access can help expedite audio system setup and commissioning while the user is in the field using a laptop.

• Copy and paste for processing blocks — To help speed up audio system design and setup, parameter settings can be quickly copied between individual processing blocks or identical groups of blocks within the graphical user environment, using conventional cut-and-paste commands.
• Presets — Using the DSP Configurator software, parameters for DSP processing, signal levels, or audio routing can be saved as up to 16 presets. These settings can be saved for the entire system, or any selected group of inputs, outputs, mixing points, and DSP blocks.
• Group masters — The DMP can consolidate gain or mute control throughout the system via group masters. Any gain or mute block within the graphical user environment can be selected and added to a group master, which can then be controlled by a single master fader and mute control. Sixteen group master controls are provided. Each group master can have up to eight members.
• Soft limits provide optimal group master adjustment range — The group master volume range can be limited using soft limits to maintain optimal minimum and maximum levels when using external volume control. This prevents operators from over- or under-adjusting levels.
• Flexible control options — The DMP 44 LC can be controlled using the DSP Configurator software and a PC connection to the RS-232 serial port, or to the USB 2.0 port on the front panel.
• Front panel USB configuration port — Enables configuration without having to access the rear panel.
• RS-232 serial control port — Using serial commands, the DMP 44 LC can be integrated into third-party control systems using SIS commands.
• Versatile mounting options — Rack-mountable 1U, quarter rack width metal enclosure.

The DMP 44 LC appears as a USB peripheral device with bidirectional communication. The USB connection can be used for software and SIS control and provides an alternative to the rear panel RS-232 port (see RS-232 connector on page 8).

Operations

Powering On and Off

To power the DMP on, plug the provided external 12 VDC, 1 A power supply into the rear panel power connector and into an AC power outlet. Unplug the power supply to power off.

Current mixing and audio processor settings—the current state of the device—are saved in nonvolatile memory. When the unit is powered off, all settings are retained. When the unit is powered back on, it recalls settings from the nonvolatile memory. If a configuration was in process during the power down, these saved mix, audio level, and audio DSP processor settings become active.

On power up, the green power and reset LEDs on the front panel (see figure 8, A) and rear panel (see figure 2, B, on page 5) blink twice, then light steadily when the unit is available for operation or configuration.

Resetting

A recessed actuator button on the rear panel (see figure 2, G, on page 5) initiates two reset modes. The green front panel LED (see figure 8, A) and rear panel LED (see figure 2, B) blink to indicate the reset modes as described in this section.

Resetting the unit causes various settings to revert to factory defaults. There are two reset modes (numbered 1 and 5 for the sake of comparison with Extron IP Link products) that are available by pressing the Reset button. This button is recessed, so you must use a pointed stylus, ballpoint pen, or small screwdriver to press it (see the Reset Modes Summary table on the next page for an explanation of the reset modes).

ATTENTION:

NOTE: Control software cannot function correctly if you use an earlier firmware version.

The default (reset) state of the DMP 44 LC is:

• Inputs 1 to 4 are mixed to corresponding outputs 1 to 4 (all other mix-points are set to 0 dB gain and muted).
• All inputs are active (unmuted, 0 dB gain).
• All outputs are active (unmuted, 100% volume).
• No inserted or active DSP processing remains.
• Group master memory is clear (empty).
• No presets are saved.
  • Digital input ports are inactive and not configured.

Software Configuration

The DSP Configurator software program provides the means to configure the DMP 44 LC so that it can function with no or minimal operator intervention. The DSP Configurator is available on the Extron website and can be installed on a PC running Windows® XP® or newer.

This section provides instructions for obtaining, installing, and using the software to configure the DMP 44 LC. Topics include:

• About the DSP Configurator
- Downloading and Installing the DSP Configurator Program
- Operating Modes
- Configuring the DMP 44 LC
- Presets
- Pulling or Pushing a Configuration and Switching to Live Mode

Certain functions of the DMP 44 LC can also be configured via Extron Simple Instruction Set (SIS) commands using a terminal emulation program such as Extron DataViewer (also available from www.extron.com). See SIS Programming and Control, beginning on page 56, for information on this type of communication.

About the DSP Configurator

The DSP Configurator is a Windows-based control program that is compatible with Windows® 2000, Windows XP, Windows 7, and later versions. It provides remote configuration and control of all DMP features and functions. This program controls the DMP through either a front panel USB connection or a rear panel RS-232 connection.

Defaults

By default, the DMP 44 LC is configured for immediate operation with each input routed to its respective output (Input 1 routed to output 1, input 2 routed to output 2, and so on). While these settings allow the device to pass audio when first connected, it rarely meets the needs of most applications. The DSP Configurator software enables you to fully configure the DMP 44 LC for your own applications. The DSP Configurator software initially opens with a blank configuration with no processing and no mixing or routing. All gain stages are set to “unity,” or 0 dB of gain.

Gain Control

Input and output gain stages provide metering in dBFS that assists you in configuring the device for optimal operation. Because the DMP 44 LC is a digital device, optimal operating levels remain close to 0 dBFS (0 dB “full scale” on the input or output meters) without ever exceeding that level. Levels above 0 dBFS cause clipping, which is always audible on a digital device.

All gain stages in the DMP are mono. Gain can also be controlled using a group master, which is configured with the DSP Configurator software. Group masters can be used to group multiple gain or mute controls, group multiple bass or treble boost and cut controls, gang two gain or mute controls for stereo operation, or even to control a single gain point. Soft limits can be applied to group masters. Sometimes a particular gain range can be too great, allowing for settings that are too loud or too soft, while in some instances the loudest settings can cause feedback or clipping. Soft limits can be used to limit the gain range for smoother operation.

Processing Tools

Finally, the DMP 44 LC provides a comprehensive set of DSP processing tools. The filter tools are available to shape the tonal quality of your source material or to equalize the room to compensate for acoustic gain. The dynamics processors are available for level control or system protection.

Operating Modes

The DSP Configurator program has two operational modes: emulate and live.

• In Emulate mode, the DMP is not connected to the host running DSP Configurator. The program provides access to all functions of the DMP 44 LC so that you can work offline to create or edit configurations. Configurations created in emulate mode do not affect DMP 44 LC operation until they are uploaded to the device.
• In Live mode, the program has established a connection and is synced with the DMP 44 LC. Changes affect the DMP in real-time, and changes in the current state of the DMP are reflected in DSP Configurator.

The DSP Configurator program always opens in emulate mode, indicated by green highlighting of Emulate button in the Mode section of the menu bar (see figure 13).

DSP Configurator - DMP44_DSPconfig4_DMP 44LC File Edit View Tools Window Help Presets: Current Emulation Ready Mode Live Enmable

Figure 13. Menu Bar at Startup in Emulate Mode

In emulate mode, you can build a new configuration from the default screen or open an existing file that contains a previously saved configuration. Settings and adjustments are saved to a configuration file at a selected location on the PC. When a previously saved file is opened in emulate mode, it becomes the current emulation displayed in the Presets field.

A new or previous file cannot be opened in live mode. You can select audio parameters in emulate mode, then transfer them to the connected DMP 44 LC after switching to live mode. You can also tailor audio settings in live mode, allowing real-time auditioning of the audio output as adjustments are made.

It is recommended that you create your configuration in emulate mode, then switch to live mode when ready to upload it to the DMP (see Pulling and Pushing a Configuration and Switching to Live Mode on page 49). However, you can switch to live mode at any time after opening the program with a blank configuration, after creating a configuration, or after loading a previously saved configuration file.

Configuring the DMP 44 LC

This section contains descriptions of the controls on the DSP Configurator Audio I/O workspace (the main screen, displayed when the DSP Configurator opens) and procedures for configuring the audio input and output and digital input ports of the DMP. For additional detailed procedures, see the DSP Configurator help file, accessed by selecting Contents from the Help menu on the main screen.

By default, the Audio I/O workspace is displayed when the DSP Configurator is opened. The diagram on this workspace (see figure 14) shows the signal flow and DSP processing per signal chain. The following sections describe the signal processing, parameter ranges, and procedures for configuring and mixing inputs and outputs using the DSP Configurator.

Processor Blocks

Processor blocks can be placed in the input and output signal chains, shown in the Audio I/O workspace diagram, to perform specific tasks. There are level control blocks, signal processor blocks, and mix-point matrix blocks (with level control). Level control processors are always active and do not have to be inserted. The following sections provide details of navigation, menus, and other interface operations. The processor blocks, while performing different functions, have several common elements.

• Insert — All blocks (except level controls) can be inserted by right-clicking on the appropriate box in the signal chain and selecting the desired block from the drop-down context menu. For example, in figure 15 a High Pass filter block has been added to the Filt (filter) box in the input signal chain.
• Remove a processor — To remove an active processors, right-click on the block and select Delete or select the block and press on the keyboard. This sets the parameters back to default and removes (deactivates) the block.

To replace an active processor, right-click it and insert a new one. A prompt appears to indicate the previous processor is about to be replaced.

• Mute — When a level block (gain, trim, or volume) is muted, all signal flow is blocked. When mute is active, a red mark appears in the lower-left corner of the block. Mix-point mute is indicated by shadowing the mix-point.
• Bypass — When bypass is active, signal flow passes through the block without processing, regardless of the settings. When bypass is removed, the signal is processed according to the parameter settings. A red mark appears in the lower-left corner of the block (shown in figure 15) to indicate that it has been inserted, but is currently bypassed.

Line Input Signal Chain

There are four mono line input channels. The channel controls and processing blocks described in this section are identical for each of the four inputs.

    D --> E["DUCK"]
    E --> F["GAIN"]

Figure 16. Line Input Channel Controls

Input signal chain elements from left to right include:

• Line input gain (GAIN) — Mono gain control with a range from -18 to +24 dB includes a mute button and is adjustable in increments of 0.1 dB. A Polarity button (click to toggle between + and -) is provided. Gain and mute controls are provided pre-meter (see Line input gain block on the next page for more information).
• Filter (FILT) — Up to three filters can be inserted for an input, in any combination of High Pass, Low Pass, Bass, Treble, or Parametric Equalizer. After a filter is inserted, you can select a new type for it from its drop-down menu on the Filter dialog box if desired (see Filter block — input on page 23 for more information).
• Dynamics (DYN) — One compressor per block, per channel. Dynamics processors vary the dynamic level, or the range of loudest to softest signals (see Dynamics processor block—input on page 29 for more information).

- Ducking (DUCK) — One ducker per block, per channel. Three levels of priority are available, at which a ducker can function as both a source and a target (as an example one source can be ducked by another source, and also trigger ducking on program channels). See Ducking block on page 31 for more information.

- Pre-mixer gain (GAIN) — One pre-mixer gain control per channel with a range of -100 dB to +6 dB, adjustable in increments of 0.1 dB. This control can be used to control program level independent of microphone mixer levels. It can also be used to compensate for any level changes due to processing (see Pre-mixer Gain block on page 34 for more information).

Line Input Gain block

Line inputs have gain settings to accommodate consumer and professional line level sources. The line input channel Gain block provides a mono long-throw fader for gain and attenuation. The range for the control is -18 to +24 dB, in steps of 0.1 dB. The default is unmuted at unity gain (0.0 dB).

Figure 33. Filter Dialog Box with Filters Added

- Within the dialog box, a filter is focused (selected) when a filter type is inserted, or when its number in the box to the left of the filter drop-down menu is clicked.

In the example in figure 34, the box for filter 3 is highlighted in yellow, indicating that it is the filter in focus. When a bypassed filter is focused (independent of other filters), it is represented in the graph as a dotted line of the same color as its filter row (and the Bypass button in its row is red). When the filter is active (not bypassed), the line is solid.

Figure 34. Filter Dialog Box, Filter Not Bypassed

- When multiple filters are enabled, the graph indicates the focused filter result (independent of other filters) in the color of the filter row background in the type or parameters table. The composite response of all filters is displayed in red.

- Above the graph, each filter has a handle that is placed directly above the cutoff or center frequency whose number corresponds to the filter number (outlined in red). Clicking a handle or clicking the table row brings focus to that filter and its handle becomes red. Click and drag the handle horizontally to change the cutoff or center frequency to a new position on the x axis.

1. If desired, add more filters as follows:

a. In the filter table at the bottom of the screen, select a filter type from the drop-down menu of the desired filter (see the example in figure 35).

b. Make any desired modifications to the new filter.

Parametric (equalizer) filters

Up to three parametric filters can be placed in the filter box at one time. Each can be set to a different frequency, creating a three-band parametric equalizer. The control boosts or cuts the center frequency. Also, by changing the Q value, you can widen or narrow the range of affected frequencies around the center frequency. In general, the higher the Q value, the narrower the affected bandwidth is.

To demonstrate how Q affects the filter, see the filter dialog box in figure 36 on the next page, which contains three parametric filters centered at different frequencies but with the same Q value of 1.0. The filter that is in focus (2) has a center frequency of 1000 Hz, boosting that frequency +12 dB over a Q of 1.0. Note that the markers on either side of the peak frequency are at 200 Hz on the left and 5000 Hz on the right, a bandwidth of about 4800 Hz.

Figure 36. Parametric Filter Dialog Box, 1000 Hz

The dialog box in the figure 36 example shows the frequency curve for a single active filter. To add its effect to the overall frequency response, deselect the Bypass button for the other filters, as shown in the figure 37.

Figure 37. All Parametric Filters Active

The overall frequency response is now shown in figure 37 as a solid red line with the filter in focus, located in row 2 and shown in the color of its table row.

The parametric filter allows frequency selection accurate to 0.1 Hz and either 6 or 12 dB of slope. Note that, at the specified frequency (100 Hz), the signal is 3 dB down, which is typical operation for high pass filters. The 3 dB down point remains constant regardless of the slope setting. Only the steepness of the frequency attenuation curve changes.

High Pass filter

The high pass filter causes all frequencies below the specified frequency to be attenuated, allowing higher frequencies to pass.

In figure 38, the frequencies lower than the specified frequency of 1kHz are attenuated, leaving the higher frequency response flat.

Figure 38. High Pass Filter Response Curve

Low Pass filter

The low pass filter is the opposite of the High Pass filter. It causes all frequencies above the specified frequency to be attenuated, allowing lower frequencies to pass. In figure 39, the frequencies higher than the specified frequency of 10 kHz are attenuated, leaving the lower frequency response flat.

Bass and treble tone filters

A tone filter, also known as a shelving filter, gives the ability to cut or boost gain evenly above or below a given frequency. The end-band shape gives the visual appearance of a shelf. Tone filters are generally applied to program material and are expressed as bass and treble control.

To set bass and treble filtering:

1. Right-click on the Filt block and select Insert > Bass & Treble Filters on the menu bar. The Filt block changes to Bass - Treb.

NOTE: Adding this filter inserts both bass and treble controls in the dialog box. If only a bass or only a treble filter is required, either click Bypass for the unneeded control or select unused from its drop-down menu.

1. Click in the box in front of the bass or treble filter that you want to adjust.

2. Enter or select the desired values Frequency, Boost, and Slope values (see the DSP Configurator help file for the details on the parameters and procedure). The following ranges can be entered or selected:

• Frequency of the controls can be selected to 0.1 Hz accuracy.
- Slopes of 6 and 12 dB/octave are available.
• You can boost or cut the signal up to 24 dB.

Dynamics Processor block - input

A dynamics processor alters the dynamic range, which is the difference between the loudest to the quietest portions of an audio signal. Each input channel has available one dynamics processor block that, when inserted, provides a compressor.

Figure 42. Input Dynamics Processor Box

Compressor

The compressor regulates the signal level by reducing the dynamic range of the input signal above a specified threshold. The input level to output level ratio determines the reduction in the dynamic range beyond the threshold setting. For example, in figure 42, with a ratio setting of 2:1, for every 2 dB of input above the threshold the compressor outputs 1 dB.

Compression is commonly used to contain mic levels within an acceptable range for maximum vocal clarity. A compressor can also make softer sounds louder in one of two ways. The dynamic range can be reduced by compressing the signal above the threshold while raising the post-compressor gain or trim (referred to as “make-up gain”). Alternately, the input signal can be increased while the compression ratio above the threshold is increased correspondingly to prevent clipping. Both techniques have the effect of making louder portions of a signal softer while at the same time increasing softer signals to raise them further above the noise floor.

Compression can also be used to protect a system or a signal chain from overload similar to a limiter.

To insert a dynamics processor into an empty block:

1. Right-click on the Dyn block for the desired input.

2. From the drop-down menu select Insert Compressor > Compressor.

NOTE: As an alternative to steps 1 through 3, you can double-click on the Dyn block, then select Compressor from the single-option pop-up menu to open this dialog box.

1. In the Compressor dialog box, enter or adjust the desired parameters. The following parameters are available:

2. 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.

3. Ratio — The input signal level reduction when compression is engaged. The ratio can be adjusted from 1.0 to 100.0 in 0.1 increments. The default is 2.0:1.
4. Attack Time — Adjusts the time delay for compression to engage after the input signal level reaches or exceeds the threshold level. Attack time can be adjusted from 0.0 to 200.0 ms in 0.1 ms increments. The default is 5.0 ms.
5. Release Time — Adjusts the time it takes to return the signal to normal (unprocessed) levels after the signal no longer exceeds the threshold level setting. Release time begins only after hold time is reached. Release time can be adjusted from 10 to 1000.0 ms in 0.1 ms increments. The default is 100.0 ms.
6. Soft Knee — Click the Soft Knee check box to smooth and soften the transition from uncompressed to compressed output levels. There are no adjustments.

Figure 45. Compressor Dialog Box

In this dialog box:

• All parameters are displayed in text boxes and can be adjusted in 0.1 increments or decrements.
• To set a parameter, enter the value in the text box to replace existing text, then pressing or tab to another field.

• The Threshold and Ratio parameters have adjustment points on the graph display. Click and drag the graph point to the desired destination or value.

• The Attack Time and Release Time parameters have horizontal sliders that allow adjustment in 1-ms increments. Adjust these parameters by either of the following methods:

• Click and drag the slider handle.
• Select (focus on) the slider, then press the and ( and ) keys to move it (adjusts in 10 ms increments).

Ducking block

Ducking provides a means to lower ("duck") the level of one or more input signal targets when a specified source must take precedence. Ducking lasts for the duration of the ducking source signal, plus hold and release time, and restores the original level of the ducking targets after the signal has ceased.

Figure 46. Ducking Box

Ducking can be useful when:

• Program material needs to attenuate in order to accentuate the voice of a narrator.
• One microphone is used by a chairman or master of ceremonies, and needs to have priority over other mics, program material, or both.
  • A paging mic must attenuate all other signals.

Only a ducking source needs to be inserted. Ducking targets are enabled from the Ducker Configuration dialog box. Any of the four inputs can be ducking sources. Any or all of the remaining inputs can be targets.

To enable ducking:

1. Right-click on the Duck block for the desired input and select Insert Ducker from the drop-down menu.

Figure 48. Ducker Configuration Dialog Box

A Current source indicator — Shows the selected input, for which the ducker settings are being entered. When a ducker dialog opens for a channel, the current source defaults to that channel. You can also select the current input by clicking the name in the Priority panel.
B Enable source mic/line check box — When this box is checked, ducking is enabled for the current source and the ducker processor block is highlighted. When the box is unchecked, ducking is disabled for the current source.
C Duck — Shows all potential input targets. Only inputs whose check boxes are selected are ducked. The current source is not available as a ducking target (a source cannot duck itself). If the current source has been designated as a target of another input channel, that channel is not available (a target cannot be the source).
D Settings — Used to configure the parameter settings for the ducker source. When a ducker block is copied, these settings are transferred.

• Threshold — Sets the input signal level in dB that the ducking source must exceed before ducking begins. If ducking does not occur soon enough to avoid loss of program material from the ducking source, decrease this setting. If ducking occurs too soon, allowing background noise to trigger ducking, increase it. The range is -60 to 0 dB in 1 dB increments. The default is -30 dB.
• Attack Time — Adjusts the time to duck the targets after the threshold is exceeded. The range is 0 to 3000 milliseconds in 1 millisecond increments. The default is 1 millisecond.
• Hold Time — Determines the time in milliseconds after a ducking source signal drops below the threshold before release time engages. The range is 0 to 10000 milliseconds in 1 millisecond increments. The default is 1000 milliseconds (1 second).
• Release — Determines the time in milliseconds that the ducking targets take to restore signal levels after the ducking source level is below the threshold and the hold time is met. The range is 10 to 10000 milliseconds in 1 millisecond increments. The default is 1000 milliseconds (1 second).

Priority — Displays the hierarchy of ducking source to duck targets. Priority levels are displayed in tree format. Input channels that are targets being ducked by a source are shown as indented below the source. Any input channel displayed in the tree is an active link. Click any input channel to select that channel as the current source. The current source indicator (figure 48, A, on the previous page) reflects the selected input channel.

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 can be required to enable an input source to take precedence over all but one other input.

In the example in figure 49, inputs 2 and 3 are set to duck when input 1 has a signal above the ducking threshold. Input 2 is set to duck input 4. In the priority tree (see figure 48, E, on the previous page, or figure 49, E), the inputs are arranged by their priority status. Input 1 has inputs 2 and 3 under it. Therefore, if input 1 exceeds the threshold, it triggers inputs 2 and 3 to duck. Similarly, input 2 has input 4 under it. Therefore, if input 2 exceeds the threshold, it triggers input 4 to duck. Since input 2 has input 4 under it, input 1 triggers inputs 2, 3 and 4.

Ducking attenuation is not additive. When an input target is ducked, regardless of how far down the priority line it is, the maximum attenuation is what is set in the “(dB):” column near the center of the dialog box (see figure 48, F, on the previous page).

Pre-mixer Gain block

The second Gain box in the Line Input chain is the pre-mixer gain control, which can be used to control program levels independent of microphone mixer levels. This gain control can also be used to compensate for any level changes due to processing. The default setting is unmuted at unity gain (0.0 dB).

Figure 50. Pre-mixer Gain Box

To set the pre-mixer gain:

1. Double-click the pre-mixer input Gain box. The Pre-mixer Gain dialog box opens.

2. To adjust the input pre-mixer signal level, do any of the following:

3. Click and hold the fader handle, then drag it to the desired level in 0.1 dB steps (direct adjustment).

4. Click or tab to the fader handle, then press the or key to increase or decrease the level in 1 dB steps. Press the or key to increase or decrease it in 5 dB steps.

5. Click in or tab to the signal level readout field. Type a new value, then either press the key to select it or press the key to move to another area.

6. Click OK to confirm the changes or Cancel to close the dialog box without making the changes.

Line Output Signal Chain

There are four mono line output channels. The channel controls and processing blocks described in this section are identical for each of the four outputs.

Figure 52. Line Output Controls

Output signal chain elements from left to right include:

• Trim (TRIM) — One post-mixer mono gain control per channel with a range of -12 dB to +6 dB, adjustable in increments of 0.1 dB.
• Filter (FILT) — Up to nine frequency filters can be inserted in any combination of High Pass, Low Pass, tone (Bass & Treble shelving), or Parametric Equalizer.
  • Dynamics (DYN) — One limiter per block per channel. The limiter prevents clipping and protects a system against component or speaker damage.
  • Volume (vOL) — One output volume control per channel with a range of -100 dB to 0 dB, adjustable in increments of 0.1 dB. Gain control is provided pre-meter. Mute control is provided post-meter. A Polarity button (click to toggle between + or -) is provided.

Trim block

The post-mixer Trim control can be used to fine-adjust the output volume. Each output TRIM block provides a single long-throw (large) fader with a gain range of -12 dB to +6 dB. The default setting is unity gain (0.0 dB).

Figure 53. Trim Block

To adjust the output gain:

1. Double-click the Trim block to open the Post-mixer Trim dialog box.

Post-mixer Tri... Output #1 6 -12 0.0 dB OK Cancel

Figure 54. Post-mixer Trim Dialog Box

2. Adjust the level using any of the following methods:

3. Click and hold the fader handle, then drag it to the desired level in 0.1 dB increments.

4. Press the or key to respectively increase or decrease the level in 0.1 dB increments.
5. Press the or key to respectively increase or decrease the level in 3 dB increments.

6. Click in the level text field (resolution is 0.1 dB increments) and enter a new value. Press or to move to another area of the dialog box.

7. Click OK to accept the changes and close the dialog box, or click Cancel to close the dialog box without saving any changes.

Filter block — output

Figure 55. Output Filter Block

The output filter function and interface are identical to the line input channel filter block, except that there are a total of nine filters allowed in the output signal processor chain. See Filter block — input on page 23 for details on adding and configuring filter blocks.

Dynamics block — limiter (output)

Each output channel has a dynamics processor block that provides a limiter function when inserted. 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.

Figure 56. Output Dynamics Processor Block

To add and configure a limiter:

1. Right-click on the Dyn block of the output to be configured, then select Insert Limiter from the context menu. The Limiter dialog box opens.

Output #1 - Limiter Output Input Threshold: -10.0 dB Soft Knee Attack Time: 2.0 ms Release Time: 50.0 ms Set Defaults OK Cancel

Figure 57. Limiter Dialog Box

1. Adjust the following settings as needed, then click OK when finished.

2. Threshold — Enter the input signal level above which limiting 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. The default is -10.0 dB.

3. Attack Time — Enter the time delay for limiting to engage after the input signal level reaches or exceeds the threshold level. Attack time can be adjusted from 0.0 to 200.0 ms in 0.1 ms increments. The default is 2.0 ms.
4. Release Time — Adjusts the time it takes to return the signal to normal (unprocessed) levels after the signal no longer exceeds the Threshold level setting. Release time begins only after hold time is reached. Release time can be adjusted from 10 to 1000.0 ms in 0.1 ms increments. The default is 50.0 ms.
5. Soft Knee — Select this check box to smooth and soften the transition from uncompressed to compressed output levels.

Volume block

Each output channel volume block provides a mono long-throw fader with a range of 0 to 100 dB of attenuation, and a volume setting readout in dB below the fader. The default settings are 0 dB attenuation and unmuted. A peak meter displays the real-time audio level from -60 to 0 dBFS.

Figure 58. Volume Block

To adjust the volume:

1. Double-click the Vol block for the desired output to open the Volume dialog box.

Mix Matrix

The DSP architecture contains a mix matrix through which incoming signals are routed to the line outputs (see figure 65, 1, on the next page). The mix matrix contains 16 mix-points, one for each input to each output bus. Each of the four line inputs is connected to a mix-point for each of the four line outputs, so that any or all of the four inputs can be routed to any or all of the four outputs. Each mix-point has a single fader with a range of -24 dB to +12 dB, adjustable in increments of 0.1 dB, plus a mute control.

Using the mix matrix, you can set mix levels from the post processing inputs to each line output bus. Mix levels are usually set relative to each other, achieving a desired blend of input signals at an optimal output level that is close to, but not exceeding 0 dBFS at the line output volume block level meter, while accounting for processing that can occur in the line output signal chain (see Line Output Signal Chain, beginning on page 35).

Presets

Presets created by DSP Configurator are used to recall a group of frequently used settings. They can contain all or a portion of the elements available within the program (gain blocks, processor blocks, and mix-points). In emulate mode, up to 16 presets can be created, then uploaded as a set and stored to the device or stored to the computer disk as a configuration file. In live mode, presets can be created one at a time from the current configuration. They can then be saved to a chosen preset number on the DMP with the option to name and save to the disk.

When recalled, a preset overwrites only elements contained in the preset. Presets are useful when settings for a particular room or only certain elements of a configuration need to be changed regularly.

Presets can be created in live or emulate mode. A preset added in live mode contains information taken from the current state of the DMP. A preset added in emulate mode contains information from the state of DSP Configurator (titled Current Emulation). Current emulation can be a configuration not yet saved as a preset (work in progress), the last preset or combination of presets recalled within DSP Configurator, or the current state of the device as a result of switching from live to emulate mode.

In emulate mode, the preset or presets are created, saved to a file, then pushed to the DMP 44 LC when it is connected in live mode.

When a pull data synchronization is performed (see Pulling or Pushing a Configuration and Selecting Live Mode on page 49), preset data remains on the DMP 44 LC with only the list of preset names pulled from the device. Presets in this state are marked with an asterisk until they are recalled (which pulls the preset data from the device), or until a backup is performed. Presets pulled from the device cannot be saved to the disk until they have been recalled, at which time the preset data is pulled into DSP Configurator. Presets with no asterisk can be saved to the disk.

Saved presets can be recalled via either the DSP Configurator or an SIS command.

Previewing and Recalling a Preset

You can preview a preset in either live or emulate mode as follows:

1. From the Presets drop-down menu, select the name of a preset to preview.

The main screen displays the selected preset configuration with a translucent green mask over each element block that will be affected if the preset is recalled (applied). All other DSP Configurator elements are left unaltered. The Presets field displays the name of the selected preset.

In the example in figure 71 on the next page, preset 1 - Input Procs was selected. Only the input filter, dynamics processor, and ducker elements are included in this preset.

1. Click the Recall button at the right of the Presets menu to apply the preset.

- In live mode: Real-time changes to the current state are not reflected on the screen while a preset is being previewed, and you cannot alter any elements. The Presets field displays Current State.

- In emulate mode — The viewed preset is applied to the current emulation. The preset field displays Current Emulation.

Building a Preset

To create a preset:

1. Highlight the desired DSP Configurator elements (processor blocks and mix-points) using the computer keyboard. Only elements that are highlighted (given focus) will be saved in the preset. Use any of the following methods as appropriate to select preset elements:

- Highlight all DSP Configurator elements on the screen:

• Press + .
• Select Tools > Presets > Mark All Items.

This marks all elements within DSP Configurator, which saves a "full" preset.

• Select a single block: Left click on the desired block.
• Select multiple blocks that are not adjacent: Hold while clicking on each desired block.
• Select multiple adjacent blocks:

- Hold while right-clicking on the first block, then the last block of either a column or a row.

- Click and drag a selected rectangle around the adjacent blocks in either a row or a column.

1. Save the selection as described under Saving a Preset, on the next page.

Saving a preset

A preset can be saved in either emulate mode or live mode.

Saving a preset in emulate mode stores that preset in the currently open file. The DSP Configurator file must then be saved to the disk (recommended), or pushed to the device after a connection is established. This differs from live mode in which the created preset is saved in real time to the device and becomes part of the configuration file.

To save a preset:

1. On the menu bar, select Tools > Presets > Save Preset.

Tools Window Help Presets... Configure Digital Inputs Connect to Device F6 Presets: Current Emulation Re Mark All Items Ctrl+A Save Preset Clear Marked Items

Figure 72. Saving a Preset

1. In the Preset Number field in the Save a Preset dialog box, select or enter a preset number (1 through 16).
2. In the Preset Name field, unassigned is shown for each preset number to which no preset has been saved. Select an unassigned preset number and enter a name of no more than 12 characters. If no name is entered, a default name is assigned. To overwrite an existing preset, select a preset with a name other than "unassigned."

OSP Save a Preset Select a preset number. In the Preset name box, unused presets are named "unassigned". To create a new preset, select an unused preset number and, if desired, type a new name. Otherwise, a default name will be assigned. To overwrite an existing preset, select a preset with a name other than "unassigned." Accept the current name or type a new one, then click OK. Preset Number: 1 Preset Name: unassigned (12 Chars Max.) OK Cancel

1. Click OK to save the preset, or Cancel to stop the save process. The Save a Preset dialog box closes.

Managing Presets

After a preset is created (whether or not the DSP Configurator file is saved), its name appears on the preset list and can be selected from the Presets menu.

1- Input Procs Current Emulation 1- Input Procs 2- Output Procs 3- Input DVD 4- Output XPA

Figure 74. Presets Menu with Saved Presets

In both live and emulate modes, after a preset is selected from the list, the following action buttons become available on the menu bar next to the Presets field:

- Recall: Recalls (makes active or applies) the preset selected from the Presets menu.

• In Live mode: Applies the currently displayed preset elements (highlighted elements) from the stored preset and overwrites that portion of the current configuration. The Presets field displays Current State.
• In Emulate mode: Applies the currently displayed preset elements (highlighted) from the file and overwrites the information contained in DSP Configurator as the current emulation. The Presets field displays Current Emulation.

- Cancel: Cancels the preset selection and returns to the current emulation (emulate mode) or state (live mode).

- Delete: Deletes the selected preset.

• In Live mode: Deletes the preset from the hardware and removes it from the Presets list. After disconnecting from the device and before exiting the program, you must save the file if you want to retain this change.
• In Emulate mode: Deletes the preset from the file in the software. You must then save the file before exiting to retain the changes.

Pulling or Pushing a Configuration and Switching to Live Mode

When finished creating or editing and saving a configuration, you must switch to live mode to upload the configuration to the DMP. When switching to live mode after making changes to the current configuration in emulate mode, you can select to:

• Pull data from the device and update the DSP Configurator program configuration. This option downloads device settings from the DMP 44 LC and synchronizes it with the DSP Configurator program overwriting the current DSP Configurator settings.
• Push data from the DSP Configurator program to the device, overwriting settings on the DMP 44 LC.

Live mode can also be used to tailor audio settings in real-time while listening to the audio output.

To switch from emulate mode to live mode:

1. Click OK. The DSP Configurator program is connected live to the device and the configuration and presets are pushed or pulled as selected.

NOTE: In either case, the program and device configuration now reflects DSP Configurator changes in real-time.

1. If changes have been made to the DSP parameters (including mix-point, gain or processor blocks) since the last file save, DSP Configurator prompts to save the file. Click Yes or No, as necessary.

DSP Configurator - DMP 44 LC Would you like to save this configuration to a file first? Yes No

Figure 77. Synchronization Confirmation

• Click Yes to save the currently open configuration to an existing file or to create a new one, then proceed to step 7.
• Click No to push the currently open configuration to the DMP 44 LC. After the configuration is complete, DSP Configurator remains connected to the DMP 44 LC in live mode.

NOTE: If the file has been previously saved and has not changed, this step is skipped.

1. Either enter a new file name or select an existing file from the list.
2. Click Save. The DSP Configurator program uploads the current file to the DMP. The file overwrites the configuration of the device, and DSP Configurator is now connected live. Further changes to the configuration are reflected immediately in the device operation.

Pulling and Pushing Presets

When a preset is pulled from the device, the preset data remains in the device until the preset has been recalled. DSP Configurator pulls only the names of the presets. These presets cannot be saved to the disk until they have been recalled. An asterisk next to the preset name indicates that only the preset name has been pulled from the device, and the preset data only exists in the device (it has not been recalled).

Presets pushed to the device or created in DSP Configurator in live mode have no asterisk. Presets with no asterisk can be saved to the disk.

Using advanced options for pushing configurations

Some advanced options are available when you are pushing a configuration. These options enable you to tailor the input, signal processing, signal mix, or output to a specific preset operation. You can push the currently open configuration, including all presets, to the DMP or you can customize the configuration push to include either the configuration, selected presets, or both.

To use the advanced push feature:

1. Connect the DMP 44 LC as described in steps 1 through 3 of the switching to live mode procedure on page 50.
2. Select the Push radio button (see figure 78, ①).

SIS Programming and Control

This section describes SIS programming and control of the DMP 44 LC, including:

• Connection Options
  • DMP 44 LC-Initiated Messages
  • Using the Command and Response Tables
  • Command and Response Table for Basic DMP 44 LC SIS Commands
  • Command and Response Tables for DMP 44 LC Audio SIS Commands

Connection Options

The DMP 44 LC can be configured and controlled using the Extron SIS (Simple Instruction Set) commands as an alternative to the DSP Configurator software (see Software Configuration beginning on page 11). The DMP can be connected to a host computer or other device (such as a control system) via the rear panel RS-232 port or the front panel USB Config port.

SIS commands can be sent to the DMP using the Extron Electronics DataViewer program, which can be downloaded from www.extron.com.

The protocol for the RS-232 port is:

• 38400 baud • No parity

- 8 data bits • No flow control

- 1 stop bit

See E RS-232 connector on page 8 for additional details on connecting to this port.

NOTES:

• The RS-232 port supports 38400 baud communication. This is a higher speed than that of many other Extron Electronics products. If using DataViewer or a similar application, make sure the PC or control system connected to these ports is set for 38400 baud.
• To use the front panel USB Config port, you must have installed the Extron USB driver (see Installing the USB Driver on page 13 for instructions).

DMP 44 LC-Initiated Messages

The DMP 44 LC initiates the following message under specific conditions. No response is required from the host. The following message is sent at power-up (RS-232 only):

(c) Copyright 20nn, Extron Electronics, DMP 44 LC, Vn.nn, 60-1095-01

Vn.nn is the firmware version number.

The DMP 44 LC sends the boot and copyright messages under the following circumstance: If the DMP 44 LC is off and an RS-232 connection is already set up (the PC is cabled to the DMP 44 LC and a serial communication program is open), the connected unit sends these messages via RS-232 when first powered on.

Using the Command and Response Tables

SIS commands consist of a string (one or more characters per command field). No special characters are required to begin or end a command sequence. When the DMP 44 LC determines a command is valid, it executes the command and sends a response to the host device. All responses end with a carriage return and a line feed (CR/LF = ←), signaling the end of the response character string.

When you are programming, certain characters are more conveniently represented by their hexadecimal rather than ASCII values. The following table shows the hexadecimal equivalent of each ASCII character:

Figure 82. ASCII to Hex Conversion Table

Error Responses

When the DMP 44 LC is unable to execute the command, it returns an error response to the host. The error response codes and their descriptions are as follows:

Code Description Code Description

E10	Invalid command	E14	Not valid for this configuration
E11	Invalid preset	E17	System timed out
E12	Invalid port number	E22	Busy
E13	Invalid parameter (out of range)	E25	Device is not present

SIS Command Types

Although the DMP 44 LC uses the same structure for all SIS commands, there are two variations. One is the global command set documented in the Command and Response Table for Basic DMP 44 LC SIS Commands. The other set of commands, documented in the Command and Response Table for DMP 44 LC Audio SIS Commands (beginning on page 63), uses the same command structure but differs in how the software addresses the individual processor blocks within the DMP 44 LC.

Special Characters

The HTML language reserves certain characters for specific functions. The device does not accept these characters as part of preset names, the device name, or locally created file names.

The DMP 44 LC rejects the following characters:

{space} (spaces are acceptable in names) + \~ , @ = ' [ ] {} < > ' " semicolon (;) colon (:) | \ and ?.

Command and Response Tables for DMP 44 LC Audio 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 can be more complex. A comprehensive understanding of the audio signal flow is helpful in understanding the commands. Figure 83 shows the specific DSP processors available for SIS commands.

NOTE: See DSP Processing and Signal Flow for a signal flow description.

Figure 83. DSP Processors Addressable via SIS Commands

The DSP Configurator program window consists of an input signal processor chain, the mixer matrix, and an output signal processing chain. The following five processors can be controlled using SIS commands:

A Line input gain control — Provides level adjustment, mute, and polarity.
B Line input pre-mixer gain — Provides basic level adjustment after the input audio processing chain and prior to the mix-point.
C Mix-points — Provide level adjustment and signal routing from the inputs to the outputs.
Output trim control — Provides level adjustment after the line input audio processing.
E Output volume control — Provides volume control of the variable output, mute, and polarity.

Reference Information

This section contains reference information for the DMP 44 LC. Topics in this section include:

• Mounting
• Updating the Firmware

Mounting

The 1U high, quarter rack width, 3-inch deep DMP 44 LC can be mounted in any of the following ways:

• Set on a table.
• Mounted on a rack shelf.
• Mounted under a desk or tabletop.
• Mounted on a projector bracket.

Tabletop Use

Each DMP 44 LC comes with rubber feet (not installed). For tabletop use, attach a self-adhesive rubber foot to each corner of the bottom of the unit.

UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the DMP 44 LC in a rack.

1. Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment can be greater than room ambient temperature. Therefore, install the unit in an environment compatible with the maximum ambient temperature (Tma = +122 °F, +50 °C) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Rack Mounting

For optional rack mounting, do not install the rubber feet. Mount the DMP 44 LC on a 19-inch Universal 1U or Basic rack shelf.

To rack mount the DMP 44 LC:

1. If rubber feet were previously installed on the bottom of the DMP 44 LC, remove them.
2. Mount the DMP 44 LC on the rack shelf using two 4-40 x 3/16 inch screws in opposite (diagonal) corners to secure the unit to the shelf.

1U Universal Rack Shelf 1/2 Rack Width Front False Faceplate 1/4 Rack Width Front False Faceplate Both front false faceplates use 2 screws. Use 2 mounting holes on opposite corners. (2) 4-40 x 3/16" Screws

Figure 84. Mounting the DMP 44 LC on a Universal Rack Shelf

1. Install black panels or other units on the rack shelf.

Furniture Mounting

Furniture mount the DMP 44 LC using the optional mounting kit as follows (see figure 85 on the next page):

1. Attach the selected mounting brackets with the machine screws provided.
2. If feet were previously installed on the bottom of the cabinet, remove them.
3. Hold the unit with the attached brackets against the underside of the table or other furniture, or against the wall. Mark the location of the screw holes of the bracket on the mounting surface.
4. Drill 3/32 inch (2 mm) diameter pilot holes, 1/4 inch (6.4 mm) deep in the mounting surface at the marked screw locations.
5. Insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until just less than 1/4 inch of the head of the screw protrudes.
6. Align the mounting screws with the slots in the brackets and place the unit against the surface, with the screws through the bracket slots.
7. Slide the unit slightly forward or back, then tighten all four screws to secure it in place.
