DMP 64 • Introduction 1

About the DMP 64 Digital Matrix Processor
The DMP 64 is a standalone audio matrix processor with 6 microphone/line inputs and 4
line outputs. Using high-quality 24-bit A/D converters sampling at 48kHz, input signals
are converted into the digital domain where Digital Signal Processing algorithms process
and mix the signals using Extron floating point ProDSP™ technology. The DMP 64 uses
a dual-matrix design providing virtual processing busses, with audio signal processing
available in any of the input, virtual, and output signal paths. A dual matrix mixer with
virtual paths provides extremely flexible architecture, allowing for versatile processing,
mixing, and routing scenarios.
The DMP 64 is IP Link-enabled connecting to a host computer via the Ethernet port for
fast configuration and setup. Dual RS-232 ports on the rear panel, plus a USB port located
on the front panel provide convenient high-speed access. Six Digital I/O ports permit
connection of switches and sensors to provide input to the system for triggering a variety
of actions within the device.
The DMP 64 has no front panel controls, therefore all configuration of DSP processors
and mixing matrixes 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 present and clip LEDs for the six input channels and four output
channels are provided on the front panel.
Two operational modes, Live and Emulate allow a user to work offline from the device to
set up a configuration and create presets and group controls as needed before placing the
configuration in the DSP 64. DSP Configurator settings developed offline can be saved to
disk as a job file to be uploaded to the device at a later time, or can be transferred directly
to the device by switching to Live mode. Up to 32 full or partial presets and up to 32
group master controls can be created, loaded into and stored in the DMP 64, and then
recalled through the DSP Configurator or a control system using SIS commands. Control
systems connected to the device either by RS-232 or Ethernet can control a limited subset
of DMP 64 functions using SIS commands.
Features
• Consumer and professional audio compatibility — Input and output line level can
be set to consumer (-10 dBV) or professional (+4 dBu).
• Inputs — Six balanced or unbalanced mic/line on 3.5 mm, 3-pole captive screw
connectors.
• Outputs — Four balanced or unbalanced on 3.5 mm, 3-pole captive screw
connectors.
• ProDSP™ audio signal processing — features 32/64-bit floating point audio DSP
processing providing wide dynamic range and maintaining audio signal transparency
while preventing DSP signal clipping and simplifying management of gain staging.
• Pro-grade hardware — Studio grade 24-bit/192 kHz analog-to-digital and digital-to-
analog converters sampling at 48 kHz.
• Low latency DSP processing — The DSP engine supports a large array of concurrent
audio processing within an audio channel and across multiple channels, while
maintaining extremely low latency from input to output.
• DSP Configurator Software — Powerful, user-friendly PC-based software tool
for managing all audio operations of the DMP 64. Enables complete setup and
configuration of digital audio processing tools on the ProDSP platform, as well as
routing and mixing.
DMP 64 • Introduction 2

• Intuitive Graphical User Environment — The DSP Configurator Software features
a Graphical User Environment with a clear view of all input and outputs, audio
processing blocks, routing, mix points, and virtual routing in a single window. This
allows a designer or installer to quickly view all audio activities without having to
access multiple windows or menus.
• 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, a user can access any
input or output, mixing points, and all audio DSP tools. Using only the keyboard for
software access can help expedite audio system setup and commissioning while on-
site using laptop PCs.
• 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.
• 32 DSP Configurator presets — Using the DSP Configurator Software, parameters
for DSP processing, signal 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,
mixing points, and DSP blocks.
• Six digital I/O ports for remote control or feedback — Six configurable digital I/O
ports are provided that enable the DMP 64 to sense and respond to external triggers
such as mic activation and muting.
• Dual matrix design — The DMP 64 employs a dual matrix design with substantial
flexibility to rout, mix, and process audio input sources. A primary matrix routes each
input to any or all four outputs. If desired, any of the six inputs can first be directed
into a secondary matrix, which routes the inputs to four virtual buses before being
mixed back to the outputs via the primary matrix. Virtual buses allow for inputs to be
grouped together and then processed with the same DSP settings and parameters,
simplifying system setup and control.
• Group masters — The DMP 64 provides the capability to consolidate gain or mute
control throughout the system. Any gain or mute block within the Graphical User
Environment can be selected and added to a group master, which can then be
controlled by a single master fader and mute control. Each group master can have up
to 16 blocks, and up to 32 group masters can be created.
• Soft limits — Soft limits can be applied to group master faders. Minimum and
maximum limits can be specified and controlled via RS-232 serial control.
• Source signal presence and clipping LEDs — The DMP 64 provides indicator LEDs
on the front panel for each input and output providing real-time monitoring of signal
presence. A separate set of LEDs illuminates as a warning when signal clipping is
detected.
• Flexible control options — The DMP 64 can be controlled using the DSP
Configurator Software and a PC connection to the IP Link Ethernet port, the RS-232
serial port, or the USB 2.0 port on the front panel.
• Front panel USB configuration port — Enables configuration without having to
access the rear panel.
• Two RS-232 ports — The DMP 64 is equipped with both primary and secondary RS-
232 serial ports for divided room applications.
• RS-232 serial control port — Using serial commands, the DMP 64 can be controlled
and configured via the Extron Windows®-based control program, or integrated into
third-party control systems using Extron SIS™ - Simple Instruction Set commands. With
two RS-232 serial ports plus the IP Link Ethernet port, the DMP 64 offers possibilities
for control in single and divisible room applications.
DMP 64 • Introduction 3

• IP Link® Ethernet monitoring and control — Engineered to meet the needs
of professional A/V environments, IP Link enables the DMP 64 to be proactively
monitored and managed over a LAN, WAN, or the Internet, using standard TCP/IP
protocols.
• Versatile mounting options — Rack-mountable 1U, half rack width metal
enclosure.
• Internal universal power supply — The 100-240 VAC, 50-60 Hz, international
power supply provides worldwide power compatibility.

DMP 64 • Introduction 4

Installation
This section describes the installation of the DMP 64, including:
• Mounting the DMP 64
• Rear Panel Features and Cabling
Mounting the DMP 64
The 1U high, half rack width, 9.5 inch deep DMP 64 Digital Matrix Processor can be:
• Set on a table,
• Mounted on a rack shelf,
• Mounted under a desk or tabletop, or
• Mounted on a projector bracket.
Tabletop Use
Each DMP 64 comes with rubber feet (not installed). For tabletop use, attach a
self-adhesive rubber foot to each corner of the bottom of the unit.
UL Rack Mounting Guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of
the DMP 64 in a rack.
1. Elevated operating ambient temperature — If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack environment may be
greater than room ambient temperature. Therefore, install the unit in an environment
compatible with the maximum ambient temperature (Tma = +122 °F, +50 °C)
specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
DMP 64 • Installation 5

Rack Mounting
For optional rack mounting, do not install the rubber feet. Mount the DMP 64
on a 19" Universal 1U or Basic rack shelf (Extron RSU 129, part #60-190-01; or

#70-077-01, under-desk; or Extron MBD 129, part #70-077-02, through-desk) as follows:
1. Attach the selected mounting brackets with the machine screws provided.
2. If feet were previously installed on the bottom of the cabinet, remove them.
Table or Wall Mounting
The table or wall mounting brackets extend approximately 1/4 inch (6.4 mm) above the
top surface of the enclosure. This design allows for an air space between the enclosure
and the surface to which it is mounted.
Table or wall mount the DMP 64 as follows:
1. Hold the unit with the attached brackets against the underside of the table or other
furniture, or against the wall. Mark the location of the screw holes of the bracket on
the mounting surface.
2. Drill 3/32 inch (2 mm) diameter pilot holes, 1/4 inch (6.4 mm) deep in the mounting
surface at the marked screw locations.
3. Insert #8 wood screws into the four pilot holes. Tighten each screw into the
mounting surface until just less than 1/4 inch of the screw’s head protrudes.
4. Align the mounting screws with the slots in the brackets and place the unit against
the surface, with the screws through the bracket slots.
5. Slide the unit slightly forward or back, then tighten all four screws to secure it in
place.

Figure 5. Power Supply Wiring
CAUTION: Always use a power supply specified by Extron Electronics for the DMP 64. Use of
an unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the DMP 64.
CAUTION: When connecting the power supply, voltage polarity is extremely important.
Applying power with incorrect voltage polarity could damage the power supply and
the DMP 64. Identify the power cord negative (ground) lead by the ridges on the
side of the cord or a black heat shrink wrapping around it.
WARNING: The two power cord wires must be kept separate while the power supply is plugged
in. Remove power before wiring.
NOTE: To verify the polarity before connection, check the no load power supply output with a
voltmeter.
CAUTION: The length of the exposed (stripped) copper wires is important. The ideal length
is 3/16 in (5 mm). Longer bare wires can short together. Shorter wires are not as
secure in the direct insertion connectors and could be pulled out.
Do not tin the stripped power supply leads. Tinned wires are not as secure in the
captive screw connectors and could be pulled out.
Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

e Digital I/O output connectors — A double-stacked 4-pole 3.5 mm captive screw
connector provides six configurable digital input or output ports allowing connection
to various devices such as motion detectors, alarms, lights, LEDs, buttons, photo (light)
sensors, temperature sensors, etc.
Digital I/O ports are used to 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 1 V 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
4-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 Digital I/O
Ports for additional information.

b Configuration connector — The USB 2.0 port uses a mini type-B connector to
connect to a host computer for control. The DMP 64 USB driver must be installed
prior to using the port. See Install the USB Driver for details.
The DMP 64 appears as a USB peripheral with bi-directional communication. The USB
connection can be used for software operation (Windows-based Program Control),
and SIS control, (Software Control).
c Input Indicators — Stacked red (signal clipping) and green (signal present) LEDs for
inputs 1 – 6 . Each stack represents one input channel.
The green signal LED varies in brightness corresponding to the real-time input signal
level. It begins to light at -60 dBFS increasing in fifteen steps to full intensity as the
signal level increases. When the signal 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.
d Output Indicators — Stacked red (signal clipping) and green (signal present) LEDs for
outputs 1 – 4 . Each LED stack represents one output channel.
The green signal LED varies in brightness corresponding to the output signal level. It
begins to light at -60 dBFS increasing to full intensity corresponding to 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.

Power Cycle
Current mixing and audio processor settings, the current state of the device, are saved in
nonvolatile memory. When the unit is powered off, all settings are retained. When the
unit is powered back on, it recalls settings from the nonvolatile memory. If a configuration
was in process during the power down, these saved mix, audio level, and audio DSP
processor settings become active.
On power up the unit performs a self-test. The front power indicator LED flashes during
the test, then light solid when the unit is available for operation or programming.
Firmware Updates
The firmware of the DMP 64 can be updated through Ethernet, USB, or RS-232
connection. The user can obtain new firmware from the Extron website, or from an Extron
Applications Engineer via e-mail. After obtaining the new firmware, upload it to the unit
via the served web pages, (see HTML Operation), using the Firmware Loader in the
DSP Configurator program (see DMP Software), or using the Extron standalone Firmware
Loader software application available on the included disc or at www.extron.com.
