About the DMP 128 Plus
The Extron DMP 128 Plus Digital Audio Matrix Processor is a 12x8 audio mixer with broad I/O expansion
capabilities including:
• 8 auxiliary inputs via VoIP (V models only), USB, and internal audio files.
• 16 x16 expansion bus
• Dante 48x24 AT channels (AT models only)
• VoIP (V models only)
• Digital I/O
The DMP 128 Plus features Extron ProDSP, automixing, AEC (Acoustic Echo Cancellation), and USB audio for
use as an audio-to-PC interface. The DMP 128 Plus offers a configuration approach to DSP to simplify mixing,
routing, conferencing, and room optimization. Quick and intuitive configuration using the Extron DSP Configurator
software allows the DMP 128 Plus to be installed in very little time with easy-to-learn adjustments that can be
applied in real-time.
A digital audio expansion port (EXP) allows two EXP-capable devices to be linked together to expand input and
output signal management and routing capabilities. The DMP 128 Plus is ideal for presentation and conferencing
applications in boardrooms, courtrooms, and conference centers requiring advanced matrix mixing and DSP.

DMP 128 Plus • Introduction 2
In addition to EXP expansion capabilities, DMP 128 Plus AT models allow connection to a Dante audio network for
transporting audio across a TCP/IP network. This further increases the DMP 128 Plus input and output expansion
capabilities.
DMP 128 Plus V models can register up to 8 VoIP lines per device. The DMP 128 Plus V can function as a VoIP
interface, removing the need for dedicated VoIP hardware.
The DMP 128 Plus has no front panel controls. All configuration is performed using the Extron DSP Configurator
software from a host computer via Ethernet (recommended) or USB. The rear panel RS-232 port allows for serial
control via SIS commands. Signal presence and clip LEDs for the twelve input channels and eight output
channels are on the front panel. Status indicators for EXP, LAN, and USB audio are also on the front panel.
Features
• 12 mic/line inputs — on 3.5 mm 3-pole and 6-pole captive screw connectors.
• 8 line level outputs — on 3.5 mm 6-pole connectors.
• Extensive 52x48 internal mix matrix —A single DMP 128 Plus can be used as the central audio processor
for a sizeable system.
• USB audio interface — The DMP 128 Plus provides up to 4 channels of digital audio sends and returns for
simplifying implementation of systems with soft-codec conferencing or computer based audio.
• Twelve channels of AEC - acoustic echo cancellation C models only — The four DMP 128 Plus C models
include twelve 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.
• VoIP capability supporting Session Initiation Protocol (V models only) — A single DMP 128 Plus V
model can be used for a single VoIP line or as a VoIP farm for up to 8 rooms.
• AT models include 48x24 Dante™ digital audio network expansion — 48 Dante inputs (Rx) and 24 Dante
outputs (Tx) via a 4-port gigabit switch allow flexibility in building large audio DSP systems with multiple DMP,
AXP, and AXI units.
• Remote port for ACP control panels — For audio systems that do not need a full control system, Extron
Audio Control Panels (ACP) offer flexible audio control, interfaced directly with the DMP 128 Plus.
• Macros — Command sequences can be sent to the local device and external devices via the LAN port. This
allows a single DMP 128 Plus to act as the central interface from a control system, sending commands to
other DMP 128 Plus and DTP CrossPoint units.
• 8 Aux I/O ports — Configurable digital audio connectivity allows these ports to be configured as VoIP audio
(V models only), USB communications audio, USB playback audio, or audio file players.
• Advanced audio processing on all 8 analog outputs and all 16 direct EXP outputs — Up to 24 speaker
zones can be implemented on one DMP 128 Plus with full processing for each zone.
• 8 audio file players — Up to 8 audio file players can be used to play back audio files for system setup or as
part of the system design. Pink noise, white noise, and sine waves are included with the device. Any WAV,
AIFF, or MP3 files up to 24-bit 48 kHz can be uploaded.
• 16 virtual processing loops – Virtual loops allows great flexibility in sub-mixing and processing.
• Lower latency — Newer, faster, and more powerful DSP chips mean maximum performance resulting in a
lower latency of 16 ms when fully loaded.
• Adaptive gain — A new adaptive gain processor that allows a given microphone input to affect levels on any
one or all other inputs and virtual returns, ensuring background music and paging are the right volume,
whether the room is quiet or noisy.

There are three ways the dual LAN ports can be configured on DMP 128 Plus V-models:
1. Control and VoIP traffic on one LAN port — Both control and VoIP traffic can be transported via a
single LAN port.
NOTE: By default, control and VoIP traffic are both transported on LAN 1.
2. Control and VoIP traffic on one LAN port using a VLAN — Both control and VoIP traffic can be
transported via a single physical LAN port while utilizing a VLAN for VoIP traffic.
3. Control and VoIP traffic on separate LAN ports — Control and VoIP traffic can be transported on
separate LAN ports with unique IP configurations.
The IP addresses can be configured via the internal web page (see Communication Settings on page 71) or
Toolbelt (see Software Installation on page 11 for details on downloading Toolbelt and the Toolbelt Help File
for device configuration).
IAT ports (AT models only) — Four RJ-45 ports form a Gigabit switch that interfaces with the AT bus. The AT
expansion bus uses Dante®protocol for digital audio networking and allows DMP 128 Plus AT models to
connect with other Dante-enabled devices to form a larger matrix (see Dante Controller on page 19 for
details on the software required to configure the AT extension bus).
The 4-port switch can be configured as two 2-port switches for redundant Dante configuration. In redundant
configuration, audio traffic is duplicated. Port 3 and 4 are primary switch (PRI), and Port 1 and 2 are the
secondary switch (SEC) (see Redundant Configuration on page 25 for details on redundant mode).
NOTE: Connecting an external power supply is not necessary when using PoE+ for power.
JUSB Audio port — Connect a Windows or Mac computer to this USB mini-B port to interface with the DMP
128 Plus as a USB audio device (see Configure USB Audio on page 15 or the DSP Configurator Help File
details on configuring the USB audio). Audio sample rate is 48 kHz/16-bit.
KReset button and LED — Initiates three levels of resets. Use a pointed stylus, ballpoint pen, or small
screwdriver to access the recessed button (see Reset Modes on page 10 for details on the different reset
modes). When not displaying reset functions, the LED operates as a power indicator and matches the front
panel power LED.

APower LED — Blinks during boot up and lights steadily when the DMP 128 Plus is operational.
BUSB Config port — One USB type mini-B port is used for configuration. This port can also be used for
firmware updates.
CEXP Activity indicator LEDs — These green activity LEDs behave differently depending on the model of
DMP 128 Plus:
• Non-AT Models
• Off — The unit is not connected to a second EXP device.
• On — The unit is connected to a second EXP device and is configured as the primary unit.
• Blinking — The unit is connected to a second EXP device and is configured as the secondary unit.
• AT Models
• On — The unit is connected to a second EXP non-AT device and is configured as the primary unit.
• Blinking — The unit is not connected to a second device.
DLAN Activity Indicator LED — Blinks to indicate rear panel LAN port activity.
EUSB Activity Indicator LED — Blinks to indicate audio streaming over USB.
FInput indicator LEDs — Stacked green and red LEDs display input signal presence and input signal clipping.
The green signal presence LED varies in brightness, corresponding to the real-time input signal level. It lights
at -60 dBFS and increases in brightness until signal level reaches -3 dBFS. When the signal reaches or
exceeds -3 dBFS, the red clip LED lights. The clip LED remains lit for 200 ms after removing the clip
condition.
GOutput indicator LEDs — Stacked red and green LEDs display output signal presence and output signal
clipping.
Output indicator LEDs function identically to the input indicator LEDs (F).

Connection Details
TP Cable Termination for Ethernet Communication
It is vital that your Ethernet cable be the correct cable type and that it be properly terminated with the correct
pinout. Ethernet links use Category (CAT) 3, 5e, or CAT 6, unshielded twisted pair (UTP) or shielded twisted pair
(STP) cables, terminated with RJ-45 connectors. Ethernet cables are limited to a length of 328 feet (100 meters).
The cable can be terminated as either a patch cable or a crossover cable (see figure 10) and must be properly
terminated for the application:
• Patch (straight-through) cable — Connection of the device to an Ethernet hub, router, or switch that also
hosts a controlling computer.
• Crossover cable — Direct connection between the processor and a controlling computer

Pins:
A cable that is wired as TIA/EIA T568A at one
end and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable wired the same at both ends is called
a "straight-through" cable because no pin/pair
assignments are swapped.
