About this Guide
This guide contains installation, configuration, and operation information for the Extron
Electronics AXP50CAT, Audio Expansion Processor.
In this manual, the AXP50CAT can also be referred to as the “AXP50,” “processor,” or
“device.”
About the AXP50CAT
The Extron AXP50CAT is a five input audio expansion processor with Extron ProDSP™
for integrating remote microphones and other sources onto a Dante™-enabled Extron
DMP128AT audio system. A single Ethernet cable to a central equipment rack can link
multiple AXP50CAT units, avoiding the effort and expense of pulling one cable for each
microphone (mic). The AXP50CAT provides 48 volt phantom power to each mic/line input.
The mixer provides dedicated signal processing for each input, including gain, filtering,
dynamics, and Acoustic Echo Cancellation (AEC). The intuitive DSP Configurator™ Software
makes it quick and easy to set up DSP parameters and AEC.
The half rack width, 9.5” (24.1cm) deep, 1U high enclosure is designed for inconspicuous
under-table placement near table microphones and line level sources.
Features
• Inputs – Five balanced or unbalanced mic/line level on 3.5 mm, 3-pole captive screw
connectors.
• AT Expansion outputs – Ten DSP AT expansion outputs, placed directly onto a Dante
audio network.
• Five mic/line level inputs with 48 volt phantom power – The AXP50CAT adds
five additional processed inputs with AEC for easy system expansion. This avoids the
need for a break-in box plus additional DSP hardware at the central rack, which may
otherwise by underutilized.
• Independent AEC – The AXP50CAT includes five 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.

AXP50CAT • Introduction 2
• Dante audio networking provides a wide range of expansion capabilities – The
Dante equipped AXP50CAT, in conjunction with the DMP128, provides scalability
for creating larger audio matrixes 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50CAT units to create larger, cost-effective audio
matrixes. Both Dante and the four-port switch are AVB ready.
• FlexInput Channels – Each input on the AXP50CAT offers FlexInput capability to
route a Dante channel in place of a local mic/line input. The flexible input selection
enables the AXP 50 C AT to process audio from remote wireless microphones,
wallplates, and other sources from anywhere on the Dante network.
• Built-in four-port Gigabit switch – Provides network pass-through to additional
AXP50CAT units and direct interconnection to DMP128AT units.
• One digital input and dual digital outputs at each mic/line input for control – The
AXP50CAT provides input, ground, and dual outputs at each mic/line input, which
allow for external triggering such as mic activation and muting, and illuminating status
LEDs.
• Compact 1U, half rack width metal enclosure – The half rack width, 9.5” (24.1cm)
deep enclosure is designed for inconspicuous under-table placement near table
microphones and line level sources using the UTS Series Under Table Shelf System or
MBU 123 Low-Profile Mount Kit, available separately.
• ProDSP 32/64-bit floating point signal processing – The AXP50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50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. This
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 AXP50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.
• Flexible pre- and post-processing input signal routing – The internal DSP
architecture of the AXP50CAT sends both pre- and post-processing input feeds from
each input onto the Dante network. This provides the flexibility to provision signals for
specific applications using unprocessed signals for recording or assistive listening, and
using processed signals for voice reinforcement and conferencing applications.
• Device Manager enables configuration of multiple Extron DSP products –
Device Manager in the DSP Configurator Software enables easy configuration of
multiple Extron DSP products, including networked AXP50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.

AXP50CAT • Introduction 3
• Flexible control options – The AXP50CAT can be controlled using the DSP
Configurator Software and a PC connection to the Ethernet port. The AXP50CAT can
also be controlled through a control system with Extron SIS - Simple Instruction Set
commands.
• 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 device, such as microphones, with preset
levels, filters, dynamics, and more. Flexible Building Blocks are available on each input
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 AXP50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50CAT. Additionally, current settings on an AXP50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, the user 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50CAT provides
LEDs on the front panel for each input, for real-time monitoring of signal presence. A
separate LED illuminates as a warning whenever analog signal clipping is detected.
• Ethernet monitoring and control – Engineered to meet the needs of professional AV
environments, Ethernet control enables the AXP50CAT to be proactively monitored
and managed over a LAN, WAN, or the Internet, using standard TCP/IP protocols.

Mounting the AXP50CAT
The 1U high, half rack width, 9.5-inch (24.1cm) deep enclosure is designed for
inconspicuous placement near table microphones and line level sources
For detailed mounting options and UL rack mounting guidelines see
MountingtheAXP50CAT on page75.
Hardware Configuration
The AXP50CAT does not have physical controls for configuration or operation.
Configuration and operation are accomplished using a PC running Windows®7®or newer
and the DSPConfigurator software (available on the Extron website, www.extron.com), or
Extron Simple Instruction Set (SIS) using DataViewer.
Dante Controller for Windows from Audinate is required to select and route Dante transmit
and recieve channels to all connected Dante-compatible devices (see Dante Controller for
Windows on page12).
The AXP50CAT has several front and rear panel operational indicators and a rear panel
reset button for hardware resets (see Reset Actuator and LED on page9).
The AXP50CAT is configured for immediate operation. While these settings allow the
device to pass audio when first connected, it rarely meets the needs of most applications.
The AXP50CAT can be fully configured using the DSP Configurator software.
The DSP Configurator software, when first launched, is a blank configuration with no
processing. All gain stages are muted and set to “unity gain,” or 0 dB of gain. Input and
output gain stages provide metering in dBFS to assist configuration of the device for optimal
operation. Optimal operating levels are close to 0 dBFS without exceeding 0dBFS (0 dB
“full scale” on the input or output meters). Levels above 0dBFS cause clipping, which is
always audible on a digital device.
The AXP50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.

LAN — 10 Mbps, 100 Mbps, 1000 Mbps halfduplex, full duplex connections are
supported. Using a standard Ethernet cable, connect to a network via one of the four
AT ports (D). The control device must be connected to the same network. Any port can
be dedicated as a control connection. Obtain the IP address of the device using Dante
Controller (see To Establish a Network Connection on page67)
NOTE: To connect the AXP50CAT directly to a computer Ethernet port, use a
crossover Ethernet cable.
When all connections are made and power is applied:
• A yellow (ACT) LED indicates data activity on the connection.
• A green (Link) LED indicates the port is connected properly to the network.
See Connection Options on page66 for additional information on Ethernet cabling.

AXP50CAT • Panels and Cabling 9
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 is in
process during the power down, the saved audio level and audio DSP processor settings
become active.
On power up, the power LED (A) lights solid when the unit is available for operation or
configuration.
Firmware Updates
The firmware of the AXP50CAT can be updated via Ethernet connection. Contact your
Extron Application Engineer for details.
Reset Actuator and LED
A recessed button on the rear panel (see figure 1, Eon page 6) initiates a reset mode.
Reset clears all processors, level controls, and mixers to default and initiates a Dante
controller reset (see Dante Controller Configuration on page59) .
NOTE: A reset closes all open IP and Telnet connections, and closes all sockets. The
rear panel reset replicates the SIS reset command (see ZAP Commands (Factory
Defaults) and RAM Commands on page70).
To Reset the AXP50CAT:
1. With power off, press and hold the rear panel reset button.
2. Apply power to the device.

Software Installation
This section describes the software requirements and installation and includes the following
topics:
• AXP50CAT Software
• Software Installation Overview
• Software Download and Installation
AXP50CAT Software
There are no hardware controls for the AXP50CAT. Configuration and operation are
accomplished using a PC running Microsoft Windows 7 or newer and the DSPConfigurator
software. DSPConfigurator customizes signal processing for the input channels of the
AXP50CAT.
In addition, Dante Controller for Windows from Audinate is required to select and route
AXP50CAT digital inputs and outputs to and from all connected Dante-compatible devices
on the same network and to rename connected devices.
To assist identification of multiple connected AXP50CATs on the network, each device
must be renamed using Dante Controller. Once the AXP50CAT is renamed, DSP
Configurator can be connected to configure it.
Both DSPConfigurator and Dante Controller are available from the AXP50CAT product
page on the Extron website (see Software Download and Installation on page12).
Signal processing for the AXP50CAT can also be controlled using the Extron Simple
Instruction Set (SIS) commands with hyperterminal or DataViewer (see Remote
Communication and Control on page66). Digital signal routing can only be done using
Dante Controller from Audinate.
See Rear Panel Features and Cabling on page6, and Connection Options on
page66 for additional details to connect via the LAN ports.

Rename Connected AXP50CAT Devices
Dante Controller auto-discovers all Dante devices on the network and advertises itself to
allow other Dante-enabled devices to communicate with it. The default device name of the
AXP50CAT is the model number followed by the last six digits of the MAC address (for
example: AXP50 - 063f70). For verification and identification, the MAC address is on a rear
panel label attached under the AT ports.
Multiple devices on the same network can present difficulty during input and output routing.
To avoid confusion, each device must be renamed to a unique identifier.
NOTE: To simplify renaming, connect only one AXP50CAT to the network at a time.
As each device is renamed, it can remain connected.
Ensure the control computer and a single AXP50CAT are connected to the same network
(see Creating a Physical Dante Network on page57).
