About This Guide
This guide contains installation, configuration, and operating information for the
ExtronElectronicsDMP64ProDSP™Digital Matrix Processor, software-controlled digital
audio processor.
In this guide, the DMP64 can also be referred to as “the mixer” or “device.”
About the DMP64 Digital Matrix Processor
The DMP64 is a standalone audio matrix processor with six microphone/line inputs and
four 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 is performed using
the Extron DSP Configurator™program from a host computer connected by any of the
communication ports: RS-232, USB or Ethernet. 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. The presets and
controls can then be recalled through DSPConfigurator, or a control system using Simple
Instruction Set(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.
DMP64 • Introduction 1

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- and 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.
• 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.
DMP64 • Introduction 2

• 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.

Figure 2. Power Supply Wiring
Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.
ATTENTION:
• The two power cord wires must be kept separate while the power supply is
plugged in. Remove power before wiring.
• 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.
• 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.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities. The power supply is to be located within the
same vicinity as the Extron AV processing equipment in an ordinary location,
Pollution Degree 2, secured to the equipment rack within the dedicated closet,
podium or desk.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
NOTES:
• 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.
• To verify the polarity before connection, check the no load power supply output
with a voltmeter.
• To avoid losing adjustments when configuring the DMP64 via SIS commands,
issue a 2FF or if using the Extron DSPConfigurator, select Tools > Save
changes to device to store the latest changes to the device. Wait several
minutes after saving the adjustments before disconnecting power.

eDigital 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, or temperature sensors.
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 on page75 for additional information).

aPower LED — The power indicator lights when the DMP64 is operational.
bConfiguration 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 on page17).
The DMP64 appears as a USB peripheral with bi-directional communication. The
USB connection can be used for software operation (see Windows-based Program
Control on page15), and SIS control (see Software Control on page14).
cInput Indicators — Stacked red (signal clipping) and green (signal present) LEDs for
inputs 1 – 6 . Each column 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.
dOutput Indicators — Stacked red (signal clipping) and green (signal present) LEDs
for outputs 1 through 4. Each LED column 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.

cPhantom Power indicators (MIC +48V) — These green LED indicators light solid
when +48 V phantom power is placed on the corresponding mic/line input. Phantom
power is not adjustable.
ATTENTION:
• Condenser microphones require phantom power. Dynamic microphones do
not require power.
• Never set an unbalanced dynamic microphone to +48V. Doing so can
damage the microphone. For condenser mics, verify the mic will safely
operate at +48 VDC.
• When a line level source is connected, be certain the +48V phantom power
is off (unchecked).
gLAN — The LAN connector has a green LED that lights solid to indicate proper
connection to an active LAN and a yellow LED that blinks to indicate data activity.
hReset — The reset actuator initiates system resets (see Reset Actuator and LED
Indicator on page12).
iPower/Reset LED — The green LED indicator adjacent to the reset button
duplicates the front panel LED operation (see Reset Actuator and LED Indicator
on page12).
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 and rear power indicator LEDs flash
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 on page120), using the Firmware
Loader in the DSPConfigurator program (see DMPSoftware on page14), or using
the Extron standalone FirmwareLoader software application available on the included disc
or at www.extron.com.
