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 DMP 44 LC may also be referred to as “the DMP” or “device.”
About the DMP 44 LC Digital Matrix Processor
The DMP 44 LC is a standalone audio matrix processor with four line inputs and four line
outputs. 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. The DMP 44 LC uses a matrix design providing audio signal processing available
in any of the input and output signal paths. A matrix mixer provides extremely flexible
architecture, allowing for versatile processing, mixing, and routing scenarios.
An RS-232 port on the rear panel, plus a USB port located on the front panel provide
convenient high-speed access. 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.
The DMP 44 LC has no front panel controls, therefore all configuration of DSP processors
and the matrix mixer is performed using the Extron DSP Configurator™ program from a host
computer via the RS-232 or USB communication ports.
Two operational modes, Live and Emulate, allow a user to work offline from the device to
set up a configuration and create presets and group controls as needed before placing the
configuration in the DMP 44 LC. DSP Configurator settings developed offline can be saved
to 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, loaded into and stored in the DMP 44 LC. Control
systems connected to the device by RS-232 can control a subset of DMP 44 LC 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 on 3.5 mm, 6-pole captive screw
connectors.
DMP 44 LC • Introduction
1
•
Outputs — Four balanced or unbalanced line 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. It features four line level inputs that can be processed, mixed, and routed to
four line level outputs.
•
DSP audio signal processing — The DMP 44 LC provides digital signal processing 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.
•
Three digital input ports for remote triggering — Three configurable digital input
ports are provided, so that external switches and sensors can be connected 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 and allow system designers to fully customize
and save their own building blocks, further streamlining audio system design and
integration.
•
Console View with gain settings, metering, and routing in a single window —
An optional view within the DSP Configurator software that allows system designers
to see all gain settings and routing, together with live metering in a single window.
Console view provides overload indication, numeric values for levels, and also 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 — Powerful, user-friendly PC-based software tool for
managing all audio operations of the DMP 44 LC. The software 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
on-site using 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.
DMP 44 LC • Introduction
2
•
16 DSP Configurator presets — Using the DSP Configurator software, parameters
for DSP processing, signal levels, or audio routing can be saved as 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 44 LC provides the capability to consolidate gain or
mute control throughout the system. 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

Power Supply Wiring
WARNING: The two power cord wires must be kept separate while the power supply is plugged
in. Remove power before wiring.
CAUTIONS: • Always use a power supply supplied by or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the end product.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities. The power supply is to be located within the
same vicinity as the Extron AV processing equipment in an ordinary location,
Pollution Degree 2, secured to the equipment rack within the dedicated closet,
podium or desk.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
CAUTION:
When connecting the power supply, voltage polarity is extremely important.
Applying power with incorrect voltage polarity could damage the power supply and
the DMP 44 LC. Identify the power cord negative (ground) lead by the ridges on the
side of the cord or a black heat shrink wrapping around it.
CAUTION:
The length of the exposed (stripped) copper wires is important. The ideal length
is 3/16 in (5 mm). Longer bare wires can short together. Shorter wires are not as
secure in the direct insertion connectors and could be pulled out.
Do not tin the stripped power supply leads. Tinned wires are not as secure in the
captive screw connectors and could be pulled out.
NOTE: To verify the polarity before connection, check the no load power supply output with a
voltmeter.
Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.
NOTE: To avoid losing adjustments when configuring the DMP 44 LC via
SIS commands issue a 2FF or if using the DSP Configurator, select
Tools > Save Changes to Device to store the latest changes to the
device. Wait several minutes after saving the adjustments before disconnecting
power.

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.com), or the Extron Simple
Instruction Set (SIS) using HyperTerminal or DataViewer.
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 DMP 44 LC can be fully configured using the DSP
Configurator software.
The DSP Configurator software, when first launched, gives you a blank configuration with
no processing and no mixing or routing. All gain stages are set to “unity gain,” or
0 dB of gain. Input and output gain stages provide metering in dBFS that will assist you in
configuring the device for optimal operation. The DMP 44 LC is a digital device, therefore
optimal operating levels are close to 0 dBFS without ever going over 0 dBFS (0 dB “full
scale” on the input or output meters). Levels above 0 dBFS cause clipping, which is always
audible on a digital device.
All gain stages in the DMP 44 LC are mono. Gain may 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/
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 may be too great, allowing for settings that are too loud or too soft, while in some
instances the loudest settings may cause feedback or clipping. Soft limits can be used to
limit the gain range for smoother operation.
Finally, the DMP 44 LC provides a comprehensive set of DSP processing tools. Use the filter
tools to shape the tonal quality of your source material or EQ the room to compensate for
acoustic gain. Use the dynamics processors for level control or system protection. The
DMP 44 LC is a versatile matrix processor for many applications.

Power Cycle
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 power/reset LED (b) lights solid when the unit is available for operation
or configuration.

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.
Reset Actuator and LED
A recessed button on the rear panel (g) initiates two reset modes. The green front panel
LED (b) and rear panel (b) LED blink to indicate the reset modes as described in the
following section. See the previous front and rear panel diagrams.
Hardware Reset Modes
With power on, when the reset button is held down the front and rear panel LEDs pulse
(blink) every three seconds and put the unit in a different reset mode. The DMP 44 LC
defaults back to the base firmware that shipped with the unit from the factory, allowing
the user to recover a unit that has incorrect code or updated firmware running.
NOTE: Control software may not function correctly if using an earlier firmware
version.
MODE 1 — Firmware reset: Disconnect power to the DMP 44 LC. Press and hold the
reset button while applying power to return the firmware to the version shipped with the
unit from the factory. This allows recovering a unit with incorrect or corrupt firmware. All
user files and settings are maintained.
MODE 5 — Factory default reset: With power on, press and hold the reset button until
the reset LED blinks 3 times (~9 seconds). Each flash will last for 0.25 seconds. Release,
then momentarily (<1 second) press the reset button to return the DMP 44 LC to factory
default conditions. If the second momentary press does not occur within 1 second, the
reset is exited.
The default (reset) state of the device 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).

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.
This section describes the signal processing including parameter ranges, and how to
mix inputs and outputs using the DSP Configurator control program. To install the DSP
Configurator program (see the “Software Control” section).
Line Input Signal Chain
Input signal chain GUI elements from left to right are as follows:
•
Gain (GAIN) — Mono gain control with a range from -18 to +24 dB includes a mute
button. Step resolution is 0.1 dB. A polarity switch (+ or -) is provided. Gain control is
provided pre-meter and mute control is provided pre-meter.
•
Filter (FILT) — Up to three filters can be inserted in any combination of High Pass,
Low Pass, Bass & Treble shelving (tone), or Parametric Equalizer.
•
Dynamics (DYN) — One compressor per block per channel. Dynamics processors vary
the dynamic level (the range of loudest to softest signals).
•
Ducking (DUCK) — One ducker per block, per channel. Each ducker can function as
either a source or a target. Three levels of priority are available, where a ducker can
function as both a source and a target (as an example, one source may be ducked by
another source, and also trigger ducking on program channels).
•
Gain (GAIN) — One pre-mixer gain control per channel with a range of -100 dB to
+6 dB. The step resolution is 0.1 dB.
DMP 44 LC • Operation
14
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 0.1 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. The step resolution is 0.1 dB. Gain control is provided pre-meter. Mute control is
provided post-meter. A polarity switch (+ or -) is provided.
Processor Blocks
Processor blocks are placed in the signal chain to perform specific tasks. There are level
control blocks, signal processor blocks and mix-point matrix blocks (with level control).
Level control processors do not have to be inserted, they are always active. 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) may be inserted by right-clicking on the
desired box and selecting from the context menu or by double-clicking and making a
selection.
•
Remove a process — Active processors can be removed by right‑clicking on the box
and selecting Delete or by selecting the block and pressing delete on the keyboard.
This sets the parameters back to default and removes or “deactivates” the block. An
active processor may be replaced by right-clicking and inserting a new processor. A
warning 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 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 will be
processed according to the parameter settings. A red mark appears in the lower left of
the block (shown below) to indicate it has been inserted, but is currently bypassed.
DMP 44 LC • Operation
15
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. Adjustments are made
using the slider or by entering the desired dB level directly into the indicator box.
Fader Handle
Gain Level
Clicking the fader handle or clicking within the fader area brings focus to the fader. The
input signal level can be adjusted using any of the following methods:
•
Direct adjustment. Click and hold the fader handle, then drag it to the desired level in
0.1 dB steps.
•
Click or tab to the fader handle, then <up arrow> or <down arrow> to the desired
level in 1 dB steps. <Page Up> and <Page Down> increases or decreases level in 10 dB
steps.
•
Click in or tab to the signal level readout field. Type a new value, then press <Enter>
or <Tab> to another area.
DMP 44 LC • Operation
16
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. All filter parameters are modified via the Filter
block dialog box. Each filter loads with all applicable default parameters displayed to the
right of each drop-down filter selection list.

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. When active (not bypassed), the line is solid.
Figure 10.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 in the type/parameters table.
The composite response of all filters is displayed in red.
Above the graph, each filter has a "handle" (circled in red above) 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.
Click+hold+dragging the handle horizontally changes the cutoff or center frequency to a
new position on the x axis.
DMP 44 LC • Operation
18
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.
To demonstrate how Q affects the filter, see the following filter block below containing
three parametric filters centered at different frequencies but with the same Q of 1.0. The
filter in focus (b) has a center frequency of 1000 Hz boosting that frequency +12 dB over
a Q of 1.0. Note 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 11.Parametric Filter Dialog Box, 1000 Hz
The above dialog box shows the frequency curve for the single active filter. To add its
effect to the overall frequency response, remove the bypass on the other filters, as shown
in the following illustration.
Figure 12.All Parametric Filters Active
The overall frequency response is now shown as a solid red line with the filter in focus,
located in row 2, shown in the color of its table row.
DMP 44 LC • Operation

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. All frequencies below the
specified frequency are attenuated allowing higher frequencies to pass.
In the figure below, the frequencies lower than the specified frequency, 1 kHz, are
attenuated leaving the higher frequency response flat.
Figure 13.High Pass Filter Response Curve
Low Pass
The low pass filter is the opposite of the High Pass filter. All frequencies above the
specified frequency are attenuated allowing lower frequencies to pass.
In the figure below, the frequencies higher than the specified frequency, 10 kHz, are
attenuated leaving the lower frequency response flat.

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). The menu appears when the
block is double-clicked, or is accessed from a context menu that appears when the block is
right-clicked (see the diagram below).
Once the processor has been inserted, individual processor parameters can be changed in
the dialog box, which is accessed by double‑clicking the processor block.
All parameters are displayed in a text box and have a resolution of 0.1 increments.
Parameters can be set by direct entry in the text box to replace existing text, then pressing
<Enter> or tabbing/clicking to another area. Threshold, gain/attenuation, target, and ratio
parameters have adjustment points on the graph display. Use the mouse to click and drag
the graph point to the desired destination/value. All time values have a horizontal slider
allowing adjustment in 1 ms increments by either a click and drag of the slider handle, or
focusing on the slider, then using <left arrow> and <right arrow> keys (<Page up> and
<Page down> keys adjust in increments of 10 ms).
Compressor
The compressor regulates 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 the diagram below,
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/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.
DMP 44 LC • Operation
27
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.
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.
Default is 5.0 ms.
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.
Default is 100.0 ms.
Soft Knee — Click the Soft Knee check box to smooth and soften the transition from
uncompressed to compressed output levels. There are no adjustments.
DMP 44 LC • Operation
28
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.
Threshold — 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.
Default is -10.0 dB.
Attack Time — Adjusts 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.
Default is 2.0 ms.
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.
Default is 50.0 ms.
Soft Knee — Click the Soft Knee check box to smooth and soften the transition from
uncompressed to compressed output levels. There are no adjustments.
Ducking
Ducking provides a means to duck, or lower 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 duck targets original
level once the ducking source signal has ceased.
Ducking may 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, or
•
A paging mic must attenuate all other signals.
Ducking processor blocks are individually inserted from a context menu, as shown in the
following figure. Only a ducking source needs to be inserted. Ducking targets are enabled
from the Ducker Configuration dialog box.
DMP 44 LC • Operation
29
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.

occurs too soon, allowing background noise to trigger ducking, increase the setting.
The range is -60 to 0 dB in 1 dB increments.
Default is -30 dB.
Attack Time — Adjusts the time to duck the targets once the threshold is exceeded.
The range is 0 to 3000 milliseconds in 1 millisecond increments.
Default is 1 millisecond.

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. Input 2 is set to duck input 4.
Notice the priority tree in the illustration below (d). 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 will trigger inputs 2 and 3 to duck. Similarly, input 2 has input 4 under it.
Therefore, if input 2 exceeds the threshold, it will trigger input 4 to duck. Since input 2 has
input 4 under it, input 1 triggers inputs 2, 3 and 4.

Figure 17.Ducker Configuration, Input Priority
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 by: column near
the center of the dialog box.

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. In general, mix levels are set
relative to each other, achieving a desired blend of input signals at an optimal output level,
close to, but not exceeding 0 dBFS at the line output Volume block level meter (while
accounting for processing that may occur in the line output signal chain).
Shown below is a drawing of the DMP 44 LC represented in DSP Configurator, with a red
box indicating the mix matrix.
From the mix matrix, any or all of the four inputs may be routed to any or all of the four
outputs.
Mix Points
Figure 18.Mix Matrix (Outlined in Red)
Clicking a mix-point brings focus to that mix-point. Double-clicking a mix-point opens a
configuration dialog window, as shown below, with the following components:
•
Mono Fader — Sets mix level to the output bus. Gain range is -24 dB to +12 dB.
Fader behavior is identical to the input channel gain block described in the line input
section with the exception that coarse adjustment <Page up> or <Page down>
increases or decreases in 5 dB increments.
•
Mute — Mutes and unmutes the signal to the output bus.
DMP 44 LC • Operation
33
•
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.
Mouse-over — The cursor changes to a hand when a mouse‑over occurs at a mix‑point
whether the mix-point contains mix information or not.
Single-click — A single click brings focus, indicated by a dark green circle around either
the ball or bubble, depending on mix status.
DMP 44 LC • Operation
34
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. Focus can be returned by
either clicking on a previously opened dialog box, or by double‑clicking on a mix-point.
DMP 44 LC • Operation
35
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.Input 1 to Output 1
In the next example figure below, input audio from all four line inputs is processed
individually and arrives at the mix-point. When the individual mix‑point mute buttons are
released, the mix-point turns teal to indicate the routing, and all four signals are routed to
output 1. Open the individual mix-point dialog boxes to adjust signal levels to the output.
Figure 20.All Inputs to Output 1
DMP 44 LC • Operation
36
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.
Filter
Filter function and interface is identical to the line input channel filter block, described
in “Filter Block.” However, there are a total of nine filters allowed in the output signal
processor chain.
DMP 44 LC • Operation
37
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.
Volume
Each output channel volume block (see the following diagram) 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. Volume level is adjustable with the slider or by entering a
value directly into the field in 0.1 dB increments. Using the arrow buttons on the keyboard
provides 1 dB increments.
An individual Mute button provides control of channel muting. Output polarity switching is
also provided with a button that toggles between positive (+) and negative (-) polarity.
The default setting is unmuted, at 0 dB attenuation. A peak meter displays the real‑time
audio level from -60 to 0 dBFS.
The OK button accepts settings and closes the dialog with a single click, while the Cancel
button ignores changes and closes the dialog.

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.
The DMP 44 LC can be set up and controlled using the Extron SIS (Simple Instruction Set)
commands or DSP Configurator software. See the “Rear Panel Features and Cabling”
section for pin assignments and details on the configuration and control port connections.
For information on DSP Configurator see “Software Control.”
SIS commands may be executed using the Extron Electronics DataViewer program, which
may be found on the Software Products DVD included with the product.
DMP 44 LC RS-232 protocol:
•
38400 baud
•
no parity
•
8 data bits
•
no flow control
•
1 stop bit
NOTE: The rear panel configuration port supports 38400 baud communication. This
is a higher speed than that of many other Extron Electronics products. If using
HyperTerminal or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.
See “RS-232 Port” for additional details on connecting the RS‑232 port.
USB port details:
The Extron USB driver must be installed before use (see “Install the USB Driver” for
driver installation instructions).
RS-232 Port
The DMP 44 LC has one serial 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. Use the protocol information listed
above to make the connection. After the connection is made, see “Using the Command/
Response Tables” later in this section for SIS programming details.

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. The DMP 44 LC-initiated messages are listed here (underlined).
© Copyright 2011, 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 such as HyperTerminal is open), the
connected unit sends these messages via RS-232 when first powered on.
Using the Command/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 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:

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:

Command/Response Table Overview
Although the DMP 44 LC uses the same structure for SIS commands, there are two
variations. One is the global command structure documented in the
“Command/Response Table for Basic SIS Commands” section that follows.
The second set of tables for DSP SIS commands uses the command structure outline
beginning with Command/Response Tables for DSP SIS Commands. While using the
same structure of basic SIS commands, they differ in how the software addresses the
individual processor blocks within the DMP 44 LC.

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.
NOTE: The entire signal flow is described in more detail in the
“DSP Processing and Signal Flow”section.

Figure 23.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 the DSP 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.
d 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.

Software Control
This section describes the control software for the DMP 44 LC, including:
•
Software Control
•
DSP Configurator Program
Software Control
The DMP 44 LC can be controlled using the DSP Configurator software, SIS commands
through HyperTerminal or DataViewer.
The DMP 44 LC has the following connection options:
•
RS-232 — One single stack 6-pole (shared with Digi In), 3.5 mm captive screw
connector is used for bi-directional RS-232 (±5 V) serial control.
See “Rear Panel Features and Cabling,” for additional details on connecting the
RS‑232 port.
•
USB 2.0 — A Mini B-type USB connector located on the front panel provides
high-speed USB 2.0 connectivity to a host computer, backward compatible to 1.0.
The DSP Configurator Control Program is compatible with Windows 2000,
Windows XP, Windows Vista®, and provides remote control of the input gain and
attenuation, output volume output adjustment, and other features.
DSP Configurator can control the DMP 44 LC via any of the two control ports, RS‑232 or
USB.
Updates to this program can be downloaded from the Extron website at
www.extron.com.
Installing the DSP Configurator Program
The program is contained on the Extron Software Products DVD.
Install the software as follows:
1. Insert the DVD into the drive
2. Click the Software tab or software icon.
NOTE: If the DVD setup program does not start automatically, run Launch.exe
from the DVD ROM directory in “My Computer” of the Windows
operating system.

3. Scroll to the DSP Configurator program and click the Install text to its right, as
shown in the red boxes below.
Figure 25. DVD Control Software Menu
4. Follow the on-screen instructions. By default, the Windows installation creates
a DSP_Configurator folder in C:\Program Files\Extron for the DSP Configurator
program files.
5. When the DSP Configurator installation is complete, the USB Installer starts
automatically. It is recommended to install the USB drivers whether they are used
immediately or not.

DSP Configurator Program
Starting the Program
1. To run the DSP Configurator Program, click
Start > Programs > Extron Electronics > DSP Configurator
> DSP Configurator.
The DSP Configurator program starts in Emulate mode (see “Emulate Mode vs.
Live Mode”).
DMP 44 LC • Software Control
54
2. Select the device to be configured and then click OK.
3. The program displays the following screen.
Using the Program
In Emulate mode, audio parameters may be selected, then transferred to the DMP 44 LC
by going to Live mode (while connected to a DMP 44 LC). See the following section.
Audio settings can also be tailored while connected to the DMP 44 LC, allowing real-time
auditioning of the audio output as adjustments are made.
DMP 44 LC • Software Control
55
Emulate Mode vs. Live Mode
The DSP Configurator program has two operational modes, Live and Emulate. In Live mode,
the program has established a connection and is synced with the DMP 44 LC. Changes
affect the device in real-time and changes in the current state of the device are reflected
in DSP Configurator. Emulate mode allows the user to work offline, creating or editing
configurations that do not affect DMP 44 LC operation until they are uploaded to the
device.
The DSP Configurator program always starts in Emulate mode. In Emulate mode, the
program provides access to all functions of the DMP 44 LC without connecting to it.
The user can build a 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 on the PC. In Emulate mode when a previously saved file is opened, it
becomes the current emulation in the Presets window. A new or previous file cannot be
opened in Live mode.
Figure 29.Main DSP Configuration Screen at Startup
The user can enter Live mode at any time after program launch, either with a blank
configuration, after creating a configuration, or after loading a previously saved
configuration file.
Synchronizing: Pull vs. Push
When switching to Live mode after making changes to the current configuration in
emulate mode, either:
•
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, or
•
Push data from the DSP Configurator program to the device, overwriting settings in
the DMP 44 LC.
Live mode can also be used to tailor audio settings in real‑time while listening to the audio
output.
DMP 44 LC • Software Control

NOTE: In either case, the program and device configuration now reflects
DSP Configurator changes in real-time.
If the file has been previously saved and has not changed, step 7 is
skipped.
10.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,
a. Click Yes to save the currently open configuration to an existing file or to create a
new one, then proceed to step 8.
b. 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.
11.Either enter a new file name, or select an existing file from the list then click Save.
The DSP Configurator program uploads the current file to the DMP 44 LC. The file
overwrites the configuration of the device, and DSP Configurator is now connected
live. Further changes to the configuration will be reflected immediately in the device
operation.
Presets
Presets are used to recall a group of frequently used settings. Presets created by
DSP Configurator may contain all elements (gain blocks, processor blocks, and mix-points)
or a portion of the elements available within the program. In Emulate mode, up to 16
presets can be created, then uploaded as a set and stored to the device or stored to disk
as a configuration file. In Live mode, presets can be created one at a time from the current
state. They can then be saved to a chosen preset number in the device, with the option to
name, rename or save to disk.
When recalled, a preset only overwrites 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.
An additional preset contains current state information if reading from the device in Live
mode, or the state of DSP Configurator if in Emulate mode (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.
Presets may be created in Live or Emulate modes. In Emulate mode, the preset or presets
are created, saved to a file, then pushed to the DMP 44 LC when connecting in Live mode.
When a Pull data synchronization is performed, preset data remains in 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 that preset is recalled (which pulls the preset data from the device),
or until a backup is performed. Presets pulled from the device cannot be saved to 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 disk.
DMP 44 LC • Software Control
59
Saved presets can be recalled via the DSP Configurator, or a control system sending an
SIS preset recall command. Presets may also be saved and recalled via the embedded web
page. Presets saved via the web page contain input gain, output volume, and the primary
mix-point settings.
Previewing/Recalling a Preset
A preset can be previewed in either Live or Emulate mode by selecting the preset from the
presets drop-down list.
Figure 32.Preset Preview
The program indicates a view-only preset configuration by displaying each preset element
with a translucent green mask over the block. In the example, the input processors are
included in Preset 1 - Input Procs.
Behavior for previewing and applying presets is as follows:
•
Live Mode — After selecting a preset, DSP Configurator displays the preset elements
that will be affected by a preset recall with a translucent mask over the element, and
leaves all other DSP Configurator elements unaltered. Elements without a translucent
mask represent elements in the current state that will be unaffected by a preset
recall. Real-time changes to the current state will not be reflected in the GUI while
previewing a preset, and the user cannot alter GUI elements. To apply the preset, the
user clicks Recall. The preset reverts to “Current State.”
•
Emulate Mode — After selecting a preset from the list, DSP Configurator displays the
elements that will be affected by a preset recall with a green translucent mask, leaving
all other elements (which represent the current emulation) unaltered. The user clicks
Recall to apply the viewed preset to the current emulation. The preset number
reverts to “Current Emulation.”
DMP 44 LC • Software Control
60
Building a Preset
Only elements that are highlighted (given focus) will be saved as a preset. <Ctrl + A>
highlights all elements within DSP Configurator.
To build a preset, highlight the desired DSP Configurator elements (gain/processor blocks,
mix-points) using standard Windows keyboard and mouse actions as follows:
1. <Left click> on the desired block to select a single block,
2. <Ctrl + left click> to select multiple blocks that are not adjacent,
3. <Shift/hold + click> on the first block and click on the last block in either a vertical
column or horizontal row to select multiple blocks, and
4. Click and drag a selection rectangle to select multiple adjacent blocks in either the
vertical or horizontal direction.
5. Go to Tools > Presets and select Mark All Items or press <Ctrl + A>. This
marks all elements within DSP Configurator, which saves a “full” preset,
6. To save the selection see “Save Preset” below.
Save Preset
A preset may 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 disk via File > Save (recommended),
and/or pushed to the device after a connection is established. This differs from Live mode
where the created preset is saved in real‑time to the device and becomes part of the
configuration file.
To save a preset use the following instructions:
1. Highlight the desired preset block by using left click, <Ctrl + left click>,
<shift + left click> or drag around the desired blocks.
2. Select Tools > Presets > Save Preset in the menu bar.
DMP 44 LC • Software Control
61
3. Select a preset number. In the Preset Name field, unused presets are named
“unassigned.” To create a new preset, select an unused preset number and type a
preset name. If no name is entered, a default name will be assigned. To overwrite an
existing preset, select a preset with a name other than “unassigned.”
Figure 33. Save Preset
4. Click OK to save the preset, or Cancel to stop the save preset operation.
Managing Presets in the GUI
After the preset is created (whether or not the DSP Configurator file is saved), it appears in
the preset list, available from the presets bar.
In Live and Emulate mode, after a preset is selected from the list, action buttons become
available next to the presets bar.
The user can either Recall (make the preset active), Cancel (return to the current emulation
or state) or Delete the preset.
In Live mode selecting Recall first applies the currently displayed preset elements
(“marked” elements) from the stored preset and overwrites that portion of the current
state, then switches the drop-down list to read “Current State.”
In Emulate mode, the Recall action button applies the currently displayed preset
elements (“marked” elements) from the file and overwrites the information contained
in DSP Configurator as the current emulation, then switches the drop‑down list to read
“Current Emulation.”
DMP 44 LC • Software Control
62
When a preset is being previewed, in either Live or Emulate mode, the Delete button
is available. In Live mode, the preset is deleted from the hardware, which is reflected in
software (it is removed from the preset list). After disconnecting from the device and
before exiting the program, the file must then be saved to retain this change. In Emulate
mode, the preset is deleted from the file in software, which must then be saved (before
exiting) to retain this change. In either Live or Emulate mode, the Cancel button
defeats the preview action and returns the user to the current state or current emulation,
respectively.
Presets: Pull vs. Push or Create Live
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 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 while in Live mode have no
asterisk. Presets with no asterisk can be saved to disk.

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 may 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” Universal 1U or Basic rack shelf (Extron RSU 126, part number 60-190-10; or
Extron RSB 126, part number 60-604-11).
To rack mount the DMP 44 LC:
1. If rubber feet were previously installed on the bottom of the DMP 44 LC, remove
QuarterRackStandardShelf
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.

Furniture Mounting
Furniture mount the DMP 44 LC using the optional mounting kit (Extron MBU 123, part
number 70-212-01, as follows:
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 untilQuarterRackUnderdeskMounting
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.
