simplifies 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.
ProDSP
ProDSP is engineered from the ground up using a powerful 64-bit
floating point DSP engine to provide very wide dynamic range, plus
studio grade 24-bit audio converters with 48 kHz sampling. ProDSP
is loaded with powerful, easy-to-configure tools to control level,
dynamics, filters, delay, ducking, loudness, and feedback suppression.
Automixer
The DMP 128 features an automixer with gated and gain sharing
modes for managing up to eight groups of microphone signals.
Gating threshold, signal level reduction, and timing parameters are
user-adjustable per channel. This allows for fine-tuning to avoid the
“chopped” sound characteristic of a traditional automixer when a
mic is gated off.
Acoustic Echo Cancellation
The DMP 128 C and DMP 128 C P models include Extron AEC
for conferencing applications. AEC is essential for effective remote
room-to-room conversations, ensuring clear, natural communication
for all participants. These models include eight independent
channels of high performance AEC, as well as selectable noise
cancellation. Extron AEC features advanced algorithms that deliver

buses to create finely tuned audio zones for the corresponding
outputs. In addition, the 12 inputs can also be routed to any of the
eight “virtual” buses to allow inputs to be processed together as
a group, before routing back into the output buses. DMP 128 AT
models include FlexInputs to provide the additional capability of
processing Dante channels from remote wireless microphones,
wallplates, and other sources anywhere on the Dante network, in
place of local mic/line inputs 1 - 8. This allows incorporating the full
range of DSP processing capabilities, including AEC, for incoming
Dante channels.
Dante Audio Networking
Dante-equipped DMP 128 AT models provide scalable audio
transport over a local area network using standard Internet
protocols. Each DMP 128 AT sends out 24 channels of digital audio
and can receive 56 channels over the network. A built-in four-port
Gigabit switch also provides direct interconnection of multiple
DMP 128 AT processors, plus AXP 50 C AT and AXP 64 C AT
expansion processors to create larger, cost-effective audio matrixes.

compromising sound quality. Throughput latency – the normal
delay of audio signals due to audio processing – is deterministic,
with very low overall latency regardless of the number of channels
and processes, so that audio is kept in sync with video. This
powerful DSP engine also delivers very wide dynamic range to
prevent clipping and fully maintain signal quality.
Fixed Yet Flexible DSP Architecture
The DSP Configurator Software features a fixed layout of DSP
processing blocks for each input, output, and virtual bus. Each block
in the Graphical User Environment represents a Gain, Dynamics,
Delay, Filter, Ducking, or FBS - Feedback Suppression algorithm
within the DSP engine. While this architecture is fixed, each block
offers flexible options and customizable parameters. For example,
the Filter block contains several selectable filters, each of which can
be customized as parametric EQ, low pass, high pass, or bass or
treble shelving. Each processing block can be selectively bypassed.

dynamics, filtering, delay, ducking, and feedback suppression. Selecting any of these
blocks opens a dedicated pop-up window with a range of options and customizable
parameters. Multiple windows can be open at the same time. Input and output levels
can be monitored at any time by simply opening any of the input or output Gain or
Volume windows.
Key Features
DIGITAL AUDIO EXPANSION PORT
An expansion port allows any two DMP 128 models to be linked together via a single shielded CAT 6 cable. The cable transports 16 incoming
and 16 outgoing expansion buses between the processors, allowing individual inputs, matrix mixes of inputs, or virtual paths to be sent to
the connected unit. Each bus carries 24-bit/48 kHz high resolution digital audio within the DMP 128. Designers can use this expanded 16x16
I/O channel transport to create audio mixes with advanced I/O and signal management scenarios combining the capabilities of two DMP 128
processors. The expansion port is also available on Extron DTP CrossPoint® matrix switchers. This allows an 8x16 I/O channel transport
between the matrix switcher and the DMP 128 to expand the number of available audio inputs for a DTP System, and to offer additional
capabilities such as automixing, AEC with DMP 128 C models, and POTS analog phone interfacing with DMP 128 C P models.

AUTOMIXER
The DMP 128 offers an automixer with gated and gain sharing modes, and includes several advanced features for optimizing microphone
management. Multiple trigger protection allows only the microphone with the highest signal to be active while the rest are gated off. The
NOM - number of open microphones can be specified to limit the number of active microphones at one time. For a natural sounding mic
mix, the automixer also offers a gain sharing mode when the NOM is bypassed, allowing all mics to gate on. A global automixer configuration
screen in the DSP Configurator Software enables fast, intuitive management of all microphones and groups in a centralized user interface.
ACOUSTIC ECHO CANCELLATION
In conferencing applications, hearing the talker’s voice returned as an echo is disruptive to natural communication. AEC processing prevents
far end audio, as reproduced in the near end, from being returned back to the remote talker as echo, ensuring clear, natural conversations.
However, AEC processing can be challenged by conditions such as double-talk, when talkers from both ends are speaking simultaneously,
and when near end talkers use wireless microphones. Extron AEC delivers fast echo cancelling optimized for these challenging conditions.
The DSP Configurator Software simplifies AEC and noise cancellation setup with a user-friendly interface that provides real-time metering for
ERL - echo return loss, ERLE - echo return loss enhancement, and TER - total echo reduction levels. Guided alerts appear whenever ERL is
outside of the optimal range for echo cancellation. Optional settings include fine adjustments for NLP - non-linear processing to maximize AEC
performance in acoustic environments with significant sonic reflections or reverberation.

Audio from the far end is reproduced by near end loudspeakers so that
listeners can hear the far end talkers. However, this audio can return
to the far end via the near end mics, DSP, and codec. To prevent this,
AEC processing in the near end analyzes two important signals, the far
end audio coming from the conferencing codec or phone input – also
known as the AEC reference, and the same audio after being played
over the near end speakers into the acoustic space and picked up by
the mics. These two signals are analyzed in order to create and apply
an adaptive filter to cancel out the far end audio captured at the mic.

All DMP 128 C models provide the flexibility to select the AEC reference

processing.
Dante Audio Networking
TECHNOLOGY OVERVIEW
Dante technology from Audinate provides digital audio distribution over standard local area
networks. Dante allows high resolution audio channels to be transported uncompressed
across a switched Ethernet data network using standard TCP/IP protocols, while meeting the
stringent quality requirements of professional audio. Dante was built on the IEEE 1588 Time
Precision Protocol standard to derive a precise clocking mechanism for synchronization. As a
result of this, latency of 1 ms is maintained across 10 network switch hops using Dante in a
Gigabit Ethernet network. Digital audio signals are converted to packets at the edge of the
network, then processed and transported to other Dante enabled devices.
A network with Dante enabled devices can be shared with ordinary data traffic such as e-mail. Audio channels can be transported as unicast
or multicast to make the most efficient use of available bandwidth.
With Dante, DMP 128 AT processors and AXP Series audio expansion processors can share multiple channels of high resolution digital
audio with each other over a local area network. They can be directly linked to other processors using their built-in four-port Gigabit Ethernet
switches or by connecting into a network infrastructure. Dante technology distributes up to 512x512 audio channels at 24-bit/48 kHz over a
single Gigabit Ethernet link with extremely low latency.
BENEFITS
An IP network of multiple DMP 128 AT and AXP Series processors provides greatly expanded I/O capacity while simplifying cable
requirements for transporting dozens or hundreds of audio channels. An input or audio mix at one unit can be directed to any of the other
devices on the network, for further DSP processing, mixing, and output to an audio destination such as a speaker zone.
A DMP 128 AT or AXP Series processor can also be used to share audio channels with third-party Dante equipped products such as
multi-channel audio recorders, amplifiers, or mixing consoles without the need to use any of its local audio input or output ports.

Dante Enabled Mixing Console
IP-based audio networking with the DMP 128 AT provides inherent scalability, allowing audio systems to be expanded simply by bringing additional processors
and third-party Dante enabled devices into the network.
Dante Audio Networking
I/O EXPANSION USING AXP SERIES EXPANSION PROCESSORS AND DANTE
AXP Series audio expansion processors are unique in the industry in offering the flexibility of Dante networking to place inputs and outputs in
remote locations with full DSP processing, including AEC, to simplify audio cabling infrastructure and reduce cable costs for integrators.
A single Ethernet cable from an AXP 50 C AT or AXP 64 C AT audio expansion processor, or several linked units, to a DMP 128 AT processor
in a central equipment rack greatly reduces the effort and expense of pulling one cable for each endpoint.
A sound system designer can incorporate several AXP Series processors to create a large mixing matrix with up to 56 remote inputs and 24
outputs per DMP 128 AT, all with 24-bit/48 kHz audio quality. In addition to using the Dante network, multiple DMP 128 AT and AXP Series

SETUP AND THE DANTE CONTROLLER SOFTWARE
Setting up a network of DMP 128 AT processors is simple and automatic. Once connected, a DMP 128 AT is self-configured with an IP
address, and discovered by other processors and Dante enabled devices on the network. A user can route audio channels between devices
using the Dante Controller software, which scans the network and provides an intuitive layout of all devices and their input and output
channels, including the DMP 128 AT processors and their 56 available inputs and 24 outputs. Making audio routing assignments between
devices is very simple with just a few clicks of a mouse.
Features
Powerful Floating Point Audio
DSP Engine
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.
Low Latency DSP Processing
The DMP 128 features very low,
deterministic latency from input to output,
regardless of the number of active channels
or processes. While latency increases in
channels with AEC enabled, and marginally
with the automixer, overall latency remains
low. This keeps audio in sync with video,
and prevents distractions to presenters or
performers resulting from delayed live audio.
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.
20 Digital I/O Ports
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
The DMP 128 employs a triple matrix
design that offers substantial flexibility in
routing, mixing, and processing audio input
sources. The primary output matrix allows
any of the 12 inputs to be matrix mixed
to any or all eight outputs. If desired, any
of the inputs can first be directed into the
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. The expansion matrix provides signal
routing between a DMP 128 and another
DMP 128 or an Extron DTP CrossPoint
matrix switcher. The expansion matrix
is also used on DMP 128 AT models to
distribute and receive audio from the Dante
network.
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.
Source 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.
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.
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.
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
linked or networked 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.
The DSP Configurator Software provides customizable filters at each input,
output, and virtual bus for fine-tuning audio system performance.

DSP Configurator
EASY-TO-USE DSP CONFIGURATOR SOFTWARE FOR FAST SETUP
The DSP Configurator Software features a Graphical User Environment that offers a clear view of all input and outputs, audio processing
blocks, and mix points for output, virtual, and expansion bus routing in a single window. This allows a designer or installer to quickly view the
entire configuration without having to access multiple windows or menus. The system view can easily be customized by hiding or collapsing
sections of the Graphical User Environment, including the inputs, outputs, virtual buses, and expansion buses. Individual channels can also be
hidden from view.
DSP Configurator
BUILDING BLOCKS
Extron Building Blocks are quick configuration tools for setting up microphones and
other sources, speakers, and microphone and program mixes within the processor.
Building Blocks provide predetermined gain levels, filters, equalization, and a
small amount of protection against signal overload at the output digital-to-analog
converters. They can be used to quickly get a sound system up and running, or as
a starting point for further system setup and fine-tuning. For additional flexibility,
system designers can customize existing Building Blocks or create their own.
DYNAMICS & DELAY
The DSP Configurator Software enables fine-tuning and adjustment of the dynamics
of all incoming and outgoing signals. Two Dynamics processing blocks are available
for each input. There is one Dynamics block on each virtual bus and output.
These blocks can be selected and customized to provide automatic gain control,
compression, limiting, or noise gating.
A Delay processing block is available for each input and output. Each delay is
adjustable up to 200 ms, and can be selected in units of time, feet, or meters. A
temperature parameter is available for distance adjustments.
FEEDBACK SUPPRESSION
The FBS - Feedback Suppression Block is used to counteract ringing due to
frequencies cycling out of control through the microphone and speakers. The feedback
suppression processor for the DMP 128 engages up to twenty notch filters with
adjustable Q. Fifteen of the filters are dynamic, and the processor automatically detects
and then reduces the ringing. Five additional fixed filters can be adjusted manually or
transferred from the dynamic filters.
FILTERING
The Filter block offers five customizable filters for each input, three for each virtual
bus, and nine for each of the four outputs. Each of these filters can be selected as
parametric EQ, low pass, high pass, or bass and treble shelving. Standard parameters
include frequency, roll-off slope, boost/cut, and Q, depending on the specific filter.
Application
COURTROOM
The DMP 128 is ideal for meeting the different functional requirements for audio in a courtroom. The automixer is a particularly beneficial
feature in courtroom proceedings, automatically managing microphone levels to maintain proper system gain before feedback and ensuring
everything is clearly heard, whether one person or multiple people are speaking. The automixer features a “chairman mode” which can gate
off all mics whenever the judge is addressing the courtroom. The DMP 128 includes eight outputs for sound reinforcement as well as an audio
recorder and ALS - assistive listening system. Presets can be created with specific mics shut off, outputs to the audio recorder muted, or
other functions or settings to support situations such as sidebar discussions between counsel and the judge.

BALLROOM
A large, divisible ballroom system requires the capability to set up and operate AV systems in various applications depending on how the
rooms are being configured. The diagram below illustrates a system design for four ballroom subdivisions. A DMP 128 AT processor is
assigned to each of the individual room audio systems. With all four processors networked together via Dante, flexible mixing and DSP
configurations can be created for a variety of audio applications and room combinations. The automixer in a DMP 128 AT can be used to
manage locally connected microphones, and also mics from other rooms. In this application, control and Dante are on separate networks.
However, since Dante uses standard TCP/IP, these networks can optionally be bridged together.

TRAINING ROOM
The DMP 128 provides a diversity of audio functions to support the various applications of a training room, including lectures, student
participation sessions, and distance learning. Two DMP 128 units handle the 20 total inputs for the instructor microphone, 15 microphones at
the workstations, program audio from permanent AV sources and guest devices, and the videoconference codec. AEC processing supports
far end talkers in a distance learning session, while the automixer self-manages the simultaneous use of several microphones during student
participation. DSP processing for gain, EQ, tone, and more can be customized and fine-tuned for the program and ceiling speaker zones.
Presets can be saved and recalled for different sound system functions based on the training room application.

DISTANCE LEARNING ROOM
Distance learning applications require a fully capable audio system to support conferencing. The audio system must deliver quality sound
reinforcement, but more importantly, ensure that audio at the far end is absolutely clear and intelligible. The best way to accomplish this is to
provide a tabletop microphone at every student location, paired with AEC in the DSP. Audio system designers can specify Extron AXP 50 C AT
input expanders at designated locations throughout the room for connecting into microphones. Instead of running mic cables all the way back
to the rack, each AXP 50 C AT connects into the main DMP 128 C AT by way of a Dante Ethernet link. Additionally, the compact enclosure of
AXP 50 C AT allows inconspicuous placement underneath a table or desk with optional Extron mounting accessories.
