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.

k AT 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).

l Telephone 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.

Cut, Copy, or Paste Functions

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

Multiple 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 can then be pasted, but succeeds if there is an exact
one-to-one relationship between the clipboard contents and the block or blocks they are
pasted into.

In the following example, the Mic #1 input signal path is copied to Mic #5. First click the
mouse and drag it 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 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>Paste command from the toolbar, or <Ctrl+V>.

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

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

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

DMP128 • Software Control 19

Click 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 is 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 gain blocks. 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 warned the action cannot be
completed.

Navigation

There are two methods of navigation around the screen:

• Keyboard • Mouse

When a new DSP Configurator file is opened, the upper left element (Output #1 Trim) is
the focus by default.

Keyboard Navigation

All screen elements including mix-points have the ability to receive focus using the tab and
arrow keys or using the arrow keys following a single click (see Keyboard Navigation on
page97).

Mouse Navigation

Left-click — Click on a processor block to bring focus to the block, as well as other
elements such as tabs, sliders, check boxes associated with the block. Other left-click
actions follow the Windows standard. In this user guide “click” always refers to a left-click
of the mouse button.

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

Double-click — Double-click on a box to open it from either the focused or unfocused
state of an element.

Tools

The Tools menu contains the following items and sub-menu:

• Presets — Provides three options:

• Mark All Items — Mark (select) all parts of the

current configuration (excluding presets), including
processors and mix-points to save as a partial preset.

• Save Preset — Save the currently marked

processors, and mix-points as a partial preset.

• Clear Marked Items — Unmark (deselect) all

parts of the current configuration (excluding presets),
including processors and mix-points.

• Protected Configuration (live mode only)—

Allows a user (typically the installer) to save and recall a
protected configuration. The protected configuration is useful to place the parameters
and values (with the exception of the device IP address) in a known state, either as
a troubleshooting tool or as a baseline configuration. The protected configuration,
once saved in the device, is always present and cannot be overwritten without
entering a user-defined Personal Identification Number (PIN) password. The protected
configuration is restored without a PIN.

NOTE: The default PIN is 0000.

• Save — Save the current configuration (excluding presets), including processors

and mixes as a password protected configuration. The DSPConfigurator
program prompts for a PIN to save.

• Recall — Recall the protected configuration.

• Change PIN — Change the PIN associated with the protected configuration.

• Configure Digital I/O — Opens a utility to configure digital I/O ports. The

DMP128 provides twenty digital I/O ports used to trigger external events from internal
actions, or for external events to trigger DMP actions (see DigitalI/OPorts on
page88).

• Connect to / Disconnect from Device (depending on Emulate or Live

mode) — Performs the same functions as the Mode Emulate and Mode Live
buttons.

• Device Manager — Opens the Device Manager dialog box. If a device is

connected, displays the details (model, MAC address, IP address). In addition, a
device can be added or removed, or a selected device cloned, and new folders can
be added to an existing device (see Device Manager on page81).

• Issue RESET Command — Initializes and clears the following: mix-points, presets,

processor blocks, and gain blocks. This reset is identical to the E ZXXX} SIS
command (see SIS Programming and Control on page129).

• Save Changes to Device (live mode only) — Saves configuration changes in the

DMP128 to non-volatile memory. This is advised if you are about to power off the
device.

• Firmware Loader — Launches the Firmware Loader program for firmware updates

(see Firmware Loader on page168).

• Organize Building Blocks — Provides organization of listed building blocks.

You can also import the building blocks file to use your set of building blocks on other
computers or export a building blocks file from another computer to use on yours (see

Signal Path Building Blocks on page105).

• Configure Groups — Opens the configure groups dialog box (see Group

Masters on page82).

• Device Settings (live mode only) — Opens a dialog box to change the

IPaddress, set administrator and user passwords, change the device name, change
the date and time, and to select the serial port baud rate.

• Network Audio Control — Launches Dante Controller to facilitate the discovery

of networked audio devices that are compliant with the network audio standard used
by the DMP128. Discovery is invoked upon launch, and retrieves device name, audio
channels, IP address and the MAC address (see Dante Controller Configuration
on page118).

• Phone Dialer — The phone dialer utility opens a dialog box that provides telephone

service capability for answering and initiating calls to remote attendees participating
in a conferencing session (see Telephone Rx (DMP128CP and DMP128CPAT

only) on page58).

• Options — Opens a tabbed dialog box that allows

customization of the DSPConfigurator appearance and
operation.

• Colors — Tailor the appearance of the various graphs

and dialog boxes. Appearance uses a selected
color scheme for the complimentary and graph colors.
Complimentary Colors allows custom selection of
colors used with the various graphs and dialog boxes.
Graph colors change the row colors containing the
information and descriptions of the graphs seen in the
processor blocks.

• Preferences — The startup splash screen contains

options for selection of the devices to connect to, or to
Always ask on startup. That selection can be changed
using Default Device.

• If Show Meters is set to True, Dynamic Block

Meters can be used to tailor the appearance

of the dynamics meters in order to use the full
meter to show input and gain reduction, or to
show the level based on the output and gain
reduction.
