AXP64CAT • Introduction 1
Introduction
This section provides an overview of this guide and the features of the Extron AXP 64CAT
Audio Expansion Processor. Topics include:
• About this Guide
• About the AXP64CAT
• Features
• AXP64CAT Application Diagrams
About this Guide
This guide contains installation, configuration, and operation information for the Extron
AXP64CAT Audio Expansion Processor. In this guide, the terms “AXP,” “AXP64,”
“AXP64CAT,” and “processor” are used interchangeably to refer to the AXP64CAT.
About the AXP64CAT
The Extron AXP64CAT is an audio expansion processor with six mic/line inputs and
four line outputs for remote connectivity to a Dante™-enabled DMP 128 audio system.
It is used to place six mic/line sources onto a Dante audio network, and route any four
Dante channels from the network to analog output for connection to an amplifier or other
destination. The AXP64CAT features Extron ProDSP with gain, filtering, and dynamics
processing for all inputs and outputs. Four of the inputs also include Acoustic Echo
Cancellation (AEC), 48 volt phantom power for each, and dedicated control ports for mic
control.
In addition, inputs 1 through 4 are FlexInput capable, allowing you to route a Dante channel
in place of a local mic/line input. A single Ethernet cable to a central equipment rack can
link multiple AXP64CAT units, avoiding the need to pull one cable for each mic/line input.
The DSP Configurator Software, downloadable free of charge from www.extron.com,
enables setup of DSP parameters and AEC.
The compact 1U high, half rack wide, 9.5-inch (24.1cm) deep enclosure can be placed on
furniture near table microphones and line level sources. It can also be mounted to a rack or
under furniture. For information on mounting options and UL rack mounting guidelines see
Mounting the AXP64CAT on page43.

AXP64CAT • Introduction 2
Features
• Inputs — Six balanced or unbalanced mic/line level processed inputs, four with AEC,
are provided on 3.5 mm, 3-pole captive screw connectors.
• Phantom power — 48-volt phantom power is provided on the first four inputs.
• Independent AEC — Four independent channels of high performance AEC, as well as
selectable noise cancellation, are provided on the first four inputs. 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.
• FlexInput Channels — The first four inputs provide FlexInput capability to route a
Dante channel in place of a local mic/line input. The flexible input selection enables the
AXP64CAT to process audio from remote wireless microphones, wallplates, and other
sources from anywhere on the Dante network.
• Flexible pre-processed and post-processed input signal routing — The internal
DSP architecture sends both pre-processed and post-processed input feeds from the
first four inputs onto the Dante network. The last two inputs provide post-processing
feeds to the Dante network. This provides the flexibility to limit the signal processing on
mic input signals for recording, assistive listening, or voice reinforcement feeds, while
applying full processing and AEC to a conferencing application.
• Outputs — Four balanced or unbalanced line level outputs are provided on a 3.5 mm,
6-pole captive screw connector.
• AT Expansion outputs — Ten DSP AT expansion outputs are placed directly onto a
Dante audio network.
• Dante-to-line level outputs — Four Dante-to-line level outputs convert Dante audio
network signals to line level output signals with filtering and dynamic processing tailored
for the local environment.
• Digital I/O — One digital input, ground, and dual digital outputs at each mic/line input
allow for external triggering, such as mic activation and muting and illuminating status
LEDs.
• Expansion through Dante audio networking — The Dante equipped AXP64CAT,
in conjunction with the DMP128, provides scalability for creating large audio
AXP64CATes over a local area network using standard Internet protocols. Dante
technology distributes up to 512x512 audio channels at 24-bit/48kHz over a
single Gigabit Ethernet link. A built-in four-port Gigabit switch also provides direct
interconnection of multiple AXP64CAT units to create large, cost-effective audio
AXP64CATes.
• Four-port Gigabit switch — The built-in, four-port Gigabit switch provides network
pass-through to additional AXP64CAT units and direct interconnection with
DMP 128AT units.
• ProDSP 32/64-bit floating point signal processing — The AXP64CAT 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.
• Studio grade 24-bit/48 kHz analog-to-digital converters — Professional
converters fully preserve the integrity of the original audio signal.
• Low latency DSP processing — The AXP64CAT 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, overall latency remains low,
keeping audio in sync with video.

AXP64CAT • Introduction 3
• DSP Configurator Software — A powerful yet user-friendly PC-based software tool
can be used for managing all audio operations of the AXP64CAT. It enables complete
setup and configuration of digital audio processing tools on the ProDSP platform.
• Intuitive Graphical User Environment — The DSP Configurator Software features
a Graphical User Environment that offers a clear view of all inputs, outputs, and audio
processing blocks in a single window. This allows a designer or installer to quickly view
an audio configuration without having to access multiple windows or menus.
• Device Manager configuration software — Device Manager in the DSP Configurator
Software enables configuration of multiple Extron DSP products, including networked
AXP64CAT 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.
• Control options — The AXP64CAT can be controlled using the DSP Configurator
Software and a PC connection to the Ethernet port. It can also be controlled through a
computer or control system with Extron Simple Instruction Set (SIS) commands.
• Copy and paste for processing blocks — For efficient 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 — Flexible Building Blocks are a set of
pre-designed processor settings optimized for a specific type of input device (such
as microphones) with preset levels, filters, dynamics, and more. Building Blocks are
available on each input strip and allow system designers to fully customize and save
their own Building Blocks for efficient system design and integration.
• Live and Emulate operation modes with configuration file saving — Live mode
allows integrators to connect to the AXP64CAT 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.
Emulate mode allows settings to be configured offline, then uploaded to the
AXP64CAT. Additionally, current settings on an AXP64CAT can be backed up to a
configuration file for archiving.
• 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, you can access any input and all audio
DSP tools. Using only the keyboard for software access can help expedite audio system
setup and optimization while on-site using laptop PCs.
• Front panel input signal presence and clipping LEDs — The AXP64CAT front
panel contains LEDs for each input, enabling real-time monitoring of signal presence. A
separate LED illuminates as a warning whenever analog signal clipping is detected.
• Ethernet monitoring and control — Ethernet control enables you to proactively
monitor and manage the AXP64CAT over a LAN, WAN, or the Internet, using standard
TCP/IP protocols.

AXP64CAT • Installation 6
Installation
This section describes the front and rear panel features and the rear panel connections. It
also provides procedures for installing the Dante Controller and DSP Configurator software.
The following topics are discussed:
• System Configuration
• Rear Panel Features and Cabling
• Front Panel Indicators
• Connecting the AXP64CAT to a Network
• Creating a Physical Dante Network
• Software Installation
• Resetting
System Configuration
The AXP64CAT does not have physical controls for configuration or operation. These are
accomplished using a computer running Windows® 10®or later and the DSPConfigurator
software (available at www.extron.com), or by SIS commands using Extron DataViewer
(also available from the Extron Website).
Dante Controller for Windows from Audinate is required to select and route Dante transmit
and receive channels to all connected Dante-compatible devices (see Downloading and
Installing Dante Controller on page23). The AXP64CAT has front and rear panel
operational indicators and a rear panel reset button for hardware resets Resetting on
page15.
You can fully configure the AXP64CAT using the DSP Configurator software. When first
launched, the DSP Configurator opens a blank configuration with no processing defined. All
gain stages are muted and set to Unity (0 dB) gain.
The AXP64CAT provides a comprehensive set of DSP processing tools. Use the filter tools
to shape the tonal quality of your microphones or EQ the room to compensate for acoustic
gain. Use the dynamics processors for level control or system protection. Input and output
gain stages provide metering in decibels relative to full scale (dBFS) to assist in configuration
of the device for optimal operation. Optimal operating levels are close to 0 dBFS (0 dB “full
scale” on the input or output meters) without exceeding that level. Levels above 0dBFS
cause clipping, which is always audible on a digital device.

Power cycle — The mixing and audio processor settings (the current state) of the AXP
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 and
reapplies them. If a configuration is in process but has not been saved when power is
removed, the previously saved audio level and audio DSP processor settings become
active.
After the AXP is powered on, the front panel power LED (see figure8, A) lights
steadily when the unit is available for operation or configuration.

BDigital I/O ports — (see figure3 on page7) Four
4-pole, 3.5 mm captive screw connectors associated with
the mic/line inputs provide digital input and output ports to
connect microphones with logic circuits. Each has an input
(IN), a ground (G), and two output (O1 and O2) ports. The
input port can enable mic mute from a remote source. The
two output ports can provide tally back to the mic LEDs
to indicate mic status. To wire these connectors, see the
illustration at right.
Do not tin the wires!

ATTENTION:
• Condenser microphones require phantom power. Dynamic microphones do
not require power.
• Les microphones électrostatiques nécessitent une alimentation fantôme. Les
microphones dynamiques n’ont pas besoin d’alimentation.
• Never set an unbalanced dynamic microphone to +48 V. Doing so may
damage the microphone.
• Ne réglez jamais un microphone dynamique asymétrique à +48V. Cela
pourrait endommager le micro.
• For condenser microphones, verify it safely operates at +48 VDC.
• Pour les microphones électrostatiques, vérifiez qu’ils fonctionnent bien à
+48Vcc.
• When a line level source is connected, be certain the +48 V phantom power is
off (cleared).
• Lorsqu’une source de niveau ligne est connectée, soyez certain que
l’alimentation fantôme +48V est débranchée (enlevée).

EAT ports — (see figure3 on page7) This four-port Gigabit switch with four RJ-45
Ethernet connectors supports digital audio transport (AT) and communications. Connect
one or more AXP64CATs to a device such as the DMP 128 AT to form a larger
AXP64CAT system (see Creating a Physical Dante Network on page12). Up to
56 channels can be connected.
NOTE: The digital and analog input channel is shared for each input. An input is
either analog or digital (Dante).
Any of these AT connectors can also be connected to an Ethernet LAN or WAN.
Communication between the AXP and a controlling device or computer is via a
TCP socket using port 4333 (see Connecting the AXP64CAT to a Network on
page11). This connection also enables control of the AXP via SIS commands issued
from a computer connected to the same LAN or WAN (see SIS Configuration and
Control starting on page34).
FReset button — (see figure3 on page7 and Resetting on page15) This
recessed button returns the AXP64CAT to its factory default state.

APower LED — This green LED blinks during boot-up. It lights steadily when the
AXP64CAT is powered on and ready to operate.
BInput LEDs — One pair for each of the six inputs:
• Clip indicators: These red LEDs light when the corresponding input signal
exceeds -3 dBFS. The clip indicator remains on for 200ms after the input signal
drops below that level.
• Signal indicators: These green LEDs light when there is an active source on the
corresponding input.
COutput LEDs — One pair for each of the four analog outputs:
• Clip indicators: These red LEDs light when the corresponding output signal
exceeds -3 dBFS. The clip indicator remains on for 200ms after the output signal
drops below that level.
• Signal indicators: These green LEDs light when a signal is detected on the
corresponding analog output.
Connecting the AXP64CAT to a Network
The AXP 64 supports 100 and 1000 Mbps halfduplex and full duplex connections. You
can use either a standard, straight-through Ethernet cable or a crossover cable to connect
the AXP to a network via one of the four AT ports (see figure3, E, on page7). The
control device must be connected to the same network. Any one of the four AT ports can
be dedicated as a control connection.
If you do not know the IP address of the control device, use Dante Controller to obtain it
(see Establishing a Network Connection on page34).
When all connections are made and power is applied, the green (activity) LED of the
connected AT port blinks to indicate data activity on the connection.

Creating a Physical Dante Network
A physical network is required to share Dante audio channels between an AXP64CAT and
DMP128AT devices. Each AXP64CAT contains a 4-port Gigabit switch with four RJ-45
connectors located on the back panel that accept standard network cables. The 4-port
switch can operate as a standard switch described in this section.
NOTE: The Dante Controller network configuration defaults to switched mode (basic)
making star and daisy-chain configurations possible.
An AXP64CAT-based Dante network can be configured in a daisy-chain or star network
topology using the 4-port switch and the Dante Controller in Switched mode.
Star Network Configuration
Star network topology has one DMP128CAT as the central unit, which is then directly
connected to up to three AXP64CATs. Alternatively, a larger network switch can be used
in place of the central DMP128CAT, allowing more than three AXP64CATs connected in
the star configuration (see figure9).

Figure 10. Daisy Chain Topology
Hybrid versions combining the star and daisy chain topologies can also be built, but a ring
topology, or any topology that creates a duplicate connection, causes a connection failure in
the Dante Controller software.
NOTE: Connections between AXP64CAT ports in either a star or daisy chain network
do not need to be sequential (port 1 to port 2, port 2 to port 3, port 3 to port 4, and
so on), nor do they need to be made between the same port numbers (port 1 to
port1, port 2 to port 2, port 3 to port 3, and so on).
