About This Manual

This manual contains installation, configuration, and operating information for the
ExtronElectronicsDMP128ProDSP™ Digital Matrix Processor, software controlled digital
audio processor.

In this manual, the DMP128 may also be referred to as “the mixer” or “device.”

About the DMP128 Digital Matrix Processor

The Extron DMP 128 Digital Matrix Processor is a 12x8 audio mixer featuring
ExtronProDSP, automixing, and I/O expansion capabilities, and is available with
AEC - acoustic echo cancellation. The DMP 128 offers a configuration approach to DSP in
order to simplify mixing, routing, conferencing, and room optimization. Quick and intuitive
configuration using the DSP Configurator™ Software allows the DMP 128 to be installed in
very little time, with easy-to-learn adjustments that can be heard in real-time. A digital audio
expansion port allows two DMP 128 units to be linked together to expand input and output
signal management and routing capabilities. The DMP 128 is ideal for presentation and
conferencing applications in boardrooms, courtrooms, and conference centers that require
advanced matrix mixing with DSP.

The DMP128 has no front panel controls. All configuration is performed using the
ExtronDSPConfigurator™ program from a host computer via any of the communication
ports, RS-232, USB or Ethernet (high-speed ports recommended). Signal presence and clip
LEDs for the twelve input channels and eight output channels are on the front panel.

Features

• Two models with 12 mic/line inputs and 8 outputs:

• 12x8 ProDSP processor

• 12x8 ProDSP processor with AEC

• Inputs — Twelve balanced or unbalanced mic/line level on 3.5 mm, 3-pole and 6-pole

captive screw connectors

• Outputs — Eight balanced or unbalanced line level on 3.5 mm, 6-pole captive screw

connectors

• Eight channels of acoustic echo cancellation (AEC) — The DMP 128 C models

include eight independent channels of high performance AEC, as well as selectable
noise cancellation. Extron AEC features advanced algorithms that deliver fast echo
canceler convergence for optimal intelligibility in situations that challenge AEC
performance, including double-talk, and the use of wireless microphones at the near
end.

DMP128 • Introduction 1

• Digital audio expansion port for linking two DMP 128 units — An expansion

port allows any two DMP 128 models to be linked together via a single shielded
CAT6 cable. This allows eight matrix mixes of the inputs, plus eight virtual paths to be
sent and received between units.

• Automixer with eight gate groups — The DMP 128 features an automixer with

advanced features for managing signal levels from multiple microphones. The
automixer includes a gating mode that automatically gates channels on or off, as well
as a gain sharing mode that maintains the overall system gain based on the number
of active mics.

• ProDSP™ audio signal processing — The DMP 128 features 32/64-bit floating

point audio DSP processing, which maintains very wide dynamic range and audio
signal transparency, to simplify management of gain staging while reducing the
possibility of DSP signal clipping.

• 48 volt phantom power — The DMP 128 is equipped with selectable 48 volt

phantom power for the first eight inputs, allowing the use of condenser microphones.

• Studio grade 24-bit/48 kHz analog-to-digital and digital-to-analog converters

— Professional converters fully preserve the integrity of the original audio signal.

• Fixed, low latency DSP processing — Input to output latency is low within

the DMP 128 and stays constant, regardless of the number of active channels or
processes. While latency increases marginally on channels with AEC enabled, overall
latency remains low. Fixed latency processing keeps audio in sync with video, and
prevents distractions to presenters or performers resulting from delayed live audio.

• DSP Configurator™ Software — A powerful yet user-friendly PC-based software

tool for managing all audio operations of the DMP 128. It enables complete setup
and configuration of digital audio processing tools on the ProDSP platform, as well as
routing and mixing.

• Intuitive Graphical User Environment — The DSP Configurator Software features

a Graphical User Environment that offers a clear view of all input and outputs, audio
processing blocks, routing, mix-points, and virtual routing in a single screen. This
allows a designer or installer to quickly view an audio configuration without having to
access multiple dialog boxes or menus.

• Device Manager enables configuration of multiple Extron DSP products

— Device Manager in the DSP Configurator Software enables easy configuration of
multiple Extron DSP products, including two linked DMP 128 processors, by toggling
between Graphical User Environments for each unit. Processors can be grouped into
folders for organizing as separate rooms or buildings. Settings for multiple Extron DSP
products in Device Manager can be saved to a single file.

• Flexible control options — The DMP 128 can be controlled using the DSP

Configurator Software and a PC connection to the Ethernet port, the RS-232 serial
port, or the USB 2.0 port on the front panel. The DMP 128 can also be controlled
through a control system with Extron SIS™ - Simple Instruction Set commands, and
by accessing the internal Web pages.

• Copy and paste for processing blocks — To help speed 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.

• Building Blocks processor settings — A collection of pre-designed processor

settings 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.

DMP128 • Introduction 2

• Live and Emulate operation modes with configuration file saving — Live

mode allows integrators to connect to the DMP 128 and make live parameter
adjustments while hearing or metering them in real-time. This avoids the need to
compile and upload a configuration file to the DSP. Emulation mode allows settings to
be configured offline, then uploaded to the DMP 128. The software also downloads
configuration files from the mixer for archiving. Settings for two DMP 128 processors
linked together can be saved to a single configuration file.

• 32 DSP Configurator presets — Using the DSP Configurator Software, any

parameters for DSP processing, 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, mix-points, and DSP blocks.

• 20 digital I/O ports for remote control or feedback — Twenty configurable digital

I/O ports are provided, so that the DMP 128 can be programmed to sense and then
respond to external triggers such as mic activation, muting, and recall of presets.

• Triple matrix design provides output, virtual, and expansion routing options—

Employs a triple matrix design that offers substantial flexibility in routing, mixing, and
processing audio input sources. An output matrix allows any of the twelve inputs to
be mixed to any or all eight outputs. If desired, any of the inputs can first be directed
into a virtual matrix, which routes the inputs to eight virtual buses, before being mixed
back into the output matrix. Virtual buses allow inputs to be processed together as
a group. When two DMP 128 processors are linked together via the expansion ports
over shielded CAT 6 cable, inputs and virtual buses of one unit can be routed to the
other processor through an expansion matrix, for additional processing or matrix
mixing into the outputs.

• Group masters — The DMP 128 provides the capability to consolidate gain or mute

control throughout the system. Gain or mute controls can be selected and added to a
group master, which can then be controlled by a single master fader or mute control.
Each group master can have up to 16 members, and up to 32 group masters can be
created.

• 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 when using digital I/O or RS-232 control. The DSP
Configurator Software provides quick drag-and-drop adjustment of soft limits from the
Group Controls screen.

• 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, the user can access
any input or output, mix-point, and all audio DSP tools. Using only the keyboard for
software access can help expedite audio system setup and optimization while on-site
using laptop PCs.

• Front panel input and output signal presence and clipping LEDs — The

DMP 128 provides LEDs on the front panel for each input and output, for real-time
monitoring of signal presence. A separate LED illuminates as a warning whenever
analog signal clipping is detected.

• Front panel USB configuration port — Enables easy configuration without having

to access the rear panel of the processor.

• Ethernet monitoring and control — Engineered to meet the needs of professional

AV environments, Ethernet control enables the DMP 128 to be proactively monitored
and managed over a LAN, WAN, or the Internet, using standard TCP/IP protocols.

• Rack-mountable — 1U, full rack width metal enclosure

Cut, Copy, or Paste Functions

The user may cut, copy, or paste a GUI processor. These actions can be performed from
a context menu accessed by a right-click of the GUI element, using the Edit menu, or
using the standard Windows keystrokes: <Ctrl+X> = cut; <Ctrl+C> = copy; <Ctrl+V> =
paste.

Multiple GUI elements may be acted upon but the blocks copied must be compatible
with the desired paste blocks. A highlighted group of elements can be cut or copied to
a clipboard. The clipboard contents may then be pasted, but will only succeed if there is
an exact one-to-one relationship between the clipboard contents and the block or blocks
pasted to.

In the following example, the Mic #1 input signal path is copied to Mic #5. First the mouse
is clicked and dragged across the entire signal path. The selected blocks are highlighted
in green. Press <Ctrl+C>, or use the Edit > Copy menu selection to copy the blocks.

As shown below, the starting point for the paste, (the upper/leftmost element), must first
be focused by left-clicking the mouse on it. Note the green focus outline that appears on
the Mic #4 Gain block. The clipboard elements are pasted using the context menu Paste
command, the Edit menu Paste command, or <Ctrl+V>.

NOTE: A cut and copy of elements may be pasted to multiple locations. To copy the

clipboard to an additional location, click on the leftmost block and paste again.

DMP128 • Software Control 21

The program warns that all settings in the section being pasted to will be overwritten:

Upon clicking Yes, the entire Mic #4 input path is now identical to the Mic #1 input path
including signal levels, parameters settings, and mute/bypass selections.

Any single processor block may be copied, then pasted to a similar processor block in
the same or different input, virtual or output signal path. Mix-point gains can be copied
from one to another. Input gain, pre-mixer gain, post-mixer trim, and output volume
can only be copied to like gains. For example, an input gain can be copied to any other
input gain, but cannot be copied to a pre-mixer gain, post-mixer trim, or output volume.
Mix-point settings can be freely copied between mix-points. The user is always asked
whether they want to overwrite the existing information. If an attempt is made to copy a
processor block setting to an incompatible block, the user is advised the action cannot be
completed.

Navigation

There are two methods of navigation around the GUI:

• Keyboard • Mouse

One element in the GUI will always retain focus. When a new DSP Configurator file is
opened, the upper left element (Output #1 Trim) will be focused by default.

Keyboard Navigation

All GUI elements including mix-points have the ability to receive focus using the tab
and arrow keys or using the arrow keys following a single left-click (see “Keyboard

Navigation” on page98).

Mouse Navigation

Left-click — A single left click brings focus to a processor block, as well as other GUI
elements such as tabs, sliders, check boxes. Other left-click actions follow the Windows
standard.

Right-click — A single right click brings up a context menu specific to the processor
block right-clicked. Other right-click actions follow the Windows standard.

Double-click — A double-click will open a dialog box from either the focused or
unfocused state of a GUI element.
