About This Guide
This guide 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 plus Dante™ audio networking. The DMP128 offers
a configuration approach to DSP to simplify mixing, routing, conferencing, and room
optimization. Quick and intuitive configuration using the DSP Configurator™ Software allows
DMP128 installation in very little time, with easy-to-learn adjustments 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
• Six models with 12 mic/line inputs, 8 outputs and Extron EXP expansion bus
include:
• DMP 128 — 12x8 ProDSP processor base unit
• DMP 128 C — 12x8 ProDSP processor with AEC
• DMP 128 AT — 12x8 ProDSP processor with Dante
• DMP 128 C AT — 12x8 ProDSP processor with AEC and Dante
• DMP 128 C P — 12x8 ProDSP processor with AEC and Phone (POTS) interface
• DMP 128 C P AT — 12x8 ProDSP processor with AEC, Phone (POTS) interface,
and Dante
DMP128 • Introduction 1

• Inputs — Twelve balanced or unbalanced mic/line level on 3.5 mm, 3-pole and
6-pole captive screw connectors, eight with phantom power.
• 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.
• Dante™ Audio Networking — Dante equipped DMP128PAT models provide
scalable audio transport over a local area network using standard Internet protocols.
Each DMP128PAT sends out 24 channels of 24-bit/48 kHz digital audio and can
receive 56 channels over the network. A built-in four-port Gigabit switch provides
direct interconnection of multiple DMP128PAT units to create larger, cost-effective
audio matrixes. Both Dante and the DMP128PAT processor four-port switch are
AVB - Audio Video Bridging ready. Dante is a trademark of Audinate®Pty Ltd.
• 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.
• 24-bit/48 kHz analog-to-digital and digital-to-analog 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.
DMP128 • Introduction 2

• Device Manager — 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 the 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 Simple Instruction Set (SIS)™ 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.
• 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.

fDigital I/O output connectors — Four 6-pole 3.5 mm captive screw connectors
each provide five configurable digital input or output ports allowing connection of up
to twenty various devices such as motion detectors, alarms, lights, LEDs, buttons,
photo (light) sensors, temperature sensors, and other devices.
Digital I/O ports monitor or drive TTL level digital signals. The inputs can be configured
to operate in one of two modes: digital input or digital output. In output mode, the
device can source up to 250mA at +5 V. In Input mode, voltages greater than 1V
indicate a logic ‘high’ signal while voltages less than 1 V indicate a logic ‘low’.
All digital I/O ports are tied to a common ground (one common ground for each
6-pole connector), but can be individually configured to operate in one of two modes:
digital input or digital output
NOTE: These ports can be configured via the DSP Configurator (see

• A green (Link) LED indicates the jack is connected properly to the network.
See SIS Programming and Control on page129 for additional information on
Ethernet cabling.
jReset button and LED indicator — The reset button returns the DMP128
to different tiers of default states and can place the unit into an event
recording mode for troubleshooting. When using the reset function, the LED
flashes to signify the different tiers (see DMP128 Hardware Reset Modes
on page169). When not in reset mode, the LED operates as a power
indicator, duplicating the front panel LED operation.
kAT connections (AT models only) — Four RJ-45 jacks for Ethernet
connection form a 4-port Gigabit switch that interfaces with the AT bus. The AT
port expansion bus uses the Dante protocol for digital media networking allowing
connection of multiple DMP128AT models to form a larger matrix.
The AT bus supports 56 channels of audio input (Rx) per DMP128AT. Output
channel support (Tx) includes the eight line outputs, eight virtual returns (post
processing), and eight expansion outputs for a total of 24 channels. Audio from an
AT port is placed on a network and the audio channels assigned to the network
are available to any Dante-compatible device on the network, such as another
DMP128AT.
NOTE: The Dante Controller software is required for configuration of the AT
expansion bus (see Dante Controller Software Installation on page113).
lTelephone connections (P models only) — These optional connections provide
telephony access.
The POTS interface provides two RJ-11 telephone jacks to connect to the incoming
phone line (LINE) and the telephone (PHONE).
The telephone interface follows all applicable US and International standards.
ATTENTION: For telephone and network cabling, to reduce the risk of fire,
use a minimum conductor size of 26 AWG, UL Listed or CSA Certified
Telecommunication Line Cord.

The green signal LED varies in brightness corresponding to the real-time input or
output signal level (see item d, below). It begins to light at – 60dBFS increasing
in steps to full intensity as the signal level increases. When the signal level reaches
– 3dBFS or above, the red clipping LED lights and remains lit as long as the signal
remains above – 3dBFS. When it falls below that level, the red LED remains lit for 200
milliseconds, after which the display resumes real-time monitoring of the signal level.
dOutput Indicators — Stacked red (signal clipping) and green (signal present) LEDs
for outputs 1 through 8. Each LED stack represents one output channel.
