Features
AXP50CAT Application Diagram
About this Guide
This guide contains installation, configuration, and operation information for the Extron
Electronics AXP50CAT, Audio Expansion Processor.
In this manual, the AXP50CAT can also be referred to as the “AXP50,” “processor,” or
“device.”
About the AXP50CAT
Features
The Extron AXP50CAT is a five input audio expansion processor with Extron ProDSP™
for integrating remote microphones and other sources onto a Dante™-enabled Extron
DMP128AT audio system. A single Ethernet cable to a central equipment rack can link
multiple AXP50CAT units, avoiding the effort and expense of pulling one cable for each
microphone (mic). The AXP50CAT 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” (24.1cm) deep, 1U high enclosure is designed for inconspicuous
under-table placement near table microphones and line level sources.
• 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 AXP50CAT 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 AXP50CAT 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.
AXP50CAT • Introduction 1
Page 8
• Dante audio networking provides a wide range of expansion capabilities – The
Dante equipped AXP50CAT, in conjunction with the DMP128, 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/48kHz
over a single Gigabit Ethernet link. A built-in four-port Gigabit switch also provides direct
interconnection of multiple AXP50CAT units to create larger, cost-effective audio
matrixes. Both Dante and the four-port switch are AVB ready.
• FlexInput Channels – Each input on the AXP50CAT 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
AXP50CAT units and direct interconnection to DMP128AT units.
• One digital input and dual digital outputs at each mic/line input for control – The
AXP50CAT 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” (24.1cm)
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 AXP50CAT 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 AXP50CAT 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 AXP50CAT. 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 AXP50CAT 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 AXP50CAT 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.
AXP50CAT • Introduction 2
Page 9
• Flexible control options – The AXP50CAT can be controlled using the DSP
Configurator Software and a PC connection to the Ethernet port. The AXP50CAT 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 AXP50CAT 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 AXP50CAT. Additionally, current settings on an AXP50CAT 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 AXP50CAT 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 AXP50CAT to be proactively monitored
and managed over a LAN, WAN, or the Internet, using standard TCP/IP protocols.

Configuration and operation are accomplished using a PC running Windows®7® or newer
and the DSPConfigurator 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 page12).
The AXP50CAT has several front and rear panel operational indicators and a rear panel
reset button for hardware resets (see Reset Actuator and LED on page9).
The AXP50CAT 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 AXP50CAT 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 0dBFS (0 dB
“full scale” on the input or output meters). Levels above 0dBFS cause clipping, which is
always audible on a digital device.
The AXP50CAT 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.

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 AXP50CAT 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, E on 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 page59) .
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 page70).
To Reset the AXP50CAT:
1. With power off, press and hold the rear panel reset button.

Software Installation
This section describes the software requirements and installation and includes the following
topics:
• AXP50CAT Software
• Software Installation Overview
• Software Download and Installation
AXP50CAT Software
There are no hardware controls for the AXP50CAT. Configuration and operation are
accomplished using a PC running Microsoft Windows 7 or newer and the DSPConfigurator
software. DSPConfigurator customizes signal processing for the input channels of the
AXP50CAT.
In addition, Dante Controller for Windows from Audinate is required to select and route
AXP50CAT 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 AXP50CATs on the network, each device
must be renamed using Dante Controller. Once the AXP50CAT is renamed, DSP
Configurator can be connected to configure it.
Both DSPConfigurator and Dante Controller are available from the AXP50CAT product
page on the Extron website (see Software Download and Installation on page12).
Signal processing for the AXP50CAT can also be controlled using the Extron Simple
Instruction Set (SIS) commands with hyperterminal or DataViewer (see Remote
Communication and Control on page66). Digital signal routing can only be done using
Dante Controller from Audinate.
See Rear Panel Features and Cabling on page6, and Connection Options on
page66 for additional details to connect via the LAN ports.
Software Installation Overview
Download and install both software programs .
Download Dante Controller for Windows from the Extron website (see Dante
Controller for Windows on page12).
Install Dante Controller.
Rename each AXPCAT as it is placed on the network (when there are multiple
AXP50CATs on the network) (see Rename Connected AXP50CAT Devices on
page14).
NOTE: To avoid confusion, rename each device with a unique identifier. To simplify
renaming, connect only one device to the network at a time. As each device is
renamed, it can remain on the network.
Download DSP Configurator (see DSPConfigurator on page17).

Rename Connected AXP50CAT 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
AXP50CAT is the model number followed by the last six digits of the MAC address (for
example: AXP50 - 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 AXP50CAT to the network at a time.
As each device is renamed, it can remain connected.
Ensure the control computer and a single AXP50CAT are connected to the same network
(see Creating a Physical Dante Network on page57).

Configuration and
Operation
This section describes the configuration and operation of the AXP50CAT using DSP
Configurator, including:
• AXP50CAT Operation
• DSP Configurator Program Basics
• DSP Processing and Signal Flow
• Output Channels
• Input Channels
• Digital I/O
• Signal Path Building Blocks
AXP50CAT Operation
The AXP50CAT is configured for immediate basic operation. While these settings allow the
device to pass audio when first connected, it will not meet the needs of many applications.
The AXP50CAT can be fully configured using the DSPConfigurator software.
When launched, the DSP Configurator software provides a blank configuration. All gain
stages are set to “unity gain,” or 0 dB. Input and output gain stages provide metering in
dBFS to assist configuration of the device for optimal operation. The AXP50CAT is a digital
device; therefore, optimal operating levels are close to 0 dBFS without going over 0 dBFS
(0dB “full scale” on the input or output meters). Levels above 0 dBFS cause clipping, which
is always audible on a digital device.
The AXP50CAT provides a comprehensive set of DSP processing tools and acoustic echo
cancellation (AEC). Use the filter tools to shape the tonal quality of your source material.
Use the dynamics processors for level control or system protection. AEC features advanced
algorithms that deliver fast echo cancel convergence for optimal intelligibility in situations
that challenge performance, including double-talk, and the use of wireless microphones at
the near end.

DSP Configurator Program Basics
When the AXP50CAT is connected to power, an audio source, and a Dante device
with an audio output, it produces audio that can easily be tailored to the listening
environment. When a different configuration is required, use the setup and control software,
DSPConfigurator, to modify and save necessary changes.
NOTE: Download and install both DSP Configurator and Dante Controller (see
AXP50CAT Software on page11) before proceeding.
Starting the Program
1. Ensure the control computer and AXP50CAT are connected to the same network (see
Creating a Physical Dante Network on page57) and the AXP50CAT is renamed
for identification (see Rename Connected AXP50CAT Devices on page14).
2. Start the DSPConfigurator software. Click
Start > Programs > Extron Electronics > DSP Configurator > DSP
Configurator.
3. From the drop-down list on the splash page, select AXP50CAT and press OK.
The main AXP50CAT screen opens (see Using the program on page21).
4. The program starts in Emulate mode (see Mode buttons on page29).
• To create a configuration offline and upload (push) it to the AXP50CAT at a later
time, remain in Emulate mode.
• To push a configuration to the device, pull a configuration from the device, or to
make immediate changes to the configuration or operation, select Live mode.
NOTE: Changing from Emulate to Live mode opens the Connect to device...
dialog box. Follow the on-screen prompts.
Using the Program
In the DSP Configurator Emulate mode, audio parameters are configured, then transferred
to the AXP50CAT by switching to Live mode. Audio settings can also be tailored while
connected to the AXP50CAT for real-time auditioning of the audio output as adjustments
are made.
The main screen contains controls for the input and output channels and provides access to
all features of the AXP50CAT.

Any single processor block is copied, then pasted to a similar processor block in the same
or different signal path. Input gain can only be copied to another input gain, and output gain
can only be copied to another output gain block. The user must always confirm that existing
information will be overwritten. If an attempt is made to copy a processor block setting to an
incompatible block, a warning dialog opens saying the action cannot be completed.

Processor Blocks
Processor blocks (E and F above) are placed in the signal chain to perform specific tasks.
There are two level control blocks and four signal processor blocks in each channel. Level
control processors do not have to be inserted, they are always active. Processor blocks are
pass-through (bypassed) until inserted.
The following sections provide details of navigation, menus, and other interface operations.
The processor blocks, while performing different functions, have several common elements.
• Insert — All blocks (except level controls) are inserted by:
• Right-click the desired block, select Insert, and click the desired processor from
the context menu, -or-
• Double-click the box and click the desired processor.
• Remove a processor — Right-click an active processor and select Delete or select
the block and press <Delete> on the keyboard. This sets the parameters back to
default and removes (bypasses) the block. To replace an active processor, right-click
and choose a different processor. A warning appears to indicate the previous processor
is about to be replaced.
• Mute — When a level block is muted, all signal flow is blocked. When mute is active a
red mark appears in the lower left of the block (see below).

Within the dialog, a filter is focused when a filter type is inserted. To focus a different filter,
click the filter number to the left of the filter selection drop-down list. Note how filter 1 in the
figure below is highlighted in yellow, indicating it is the filter in focus. The results of the filter
in focus (independent of other filters) displays in the graph as a dotted line of the same color
as its filter row when bypassed. When active (not bypassed), the line is solid.

Parametric (equalizer) filter
A filter block can have up to five parametric filters inserted. Each parameteric filter can be
set to a different frequency, creating a 5-band parametric equalizer. The control boosts
or cuts the center frequency by up to 24 dB, and by changing the Q value, the range of
affected frequencies is widened or narrowed around the center frequency. In general, as Q
increases, the affected bandwidth narrows.
To demonstrate how Q affects the filter, see the following filter (below) containing five
parametric filters centered at different frequencies but with the same Q of 1.0. The filter in
focus (filter 3 in figure 17) has a center frequency of 1000 Hz boosting that frequency +12
dB over a Q of 1.0. Note the markers on either side of the peak frequency are at 300 Hz on
the left and 3000 Hz on the right, a bandwidth of about 2700 Hz.
Figure 17. Parametric Filter Dialog Box, 1000 Hz
The above dialog shows the frequency curve for the single active filter. To add its effect to
the overall frequency response, remove the bypass on the other filters, as shown below.
Figure 18. All Parametric Filters Active
The overall frequency response is now a solid red line in figure 18.
The parametric filter allows frequency selection accurate to 0.1 Hz and + 24dB of slope.

High Pass filter
The high pass filter is the opposite of the low pass filter. All frequencies below the specified
frequency are attenuated allowing higher frequencies to pass.
In the figure below, the frequencies lower than the specified frequency, 1 kHz, are
attenuated leaving the higher frequency response flat.
Figure 19. High Pass Filter Response Curve
Low Pass filter
The low pass filter is the opposite of the high pass filter. All frequencies above the specified
frequency are attenuated allowing lower frequencies to pass.
In the figure below, the frequencies higher than the specified frequency, 10 kHz, are
attenuated leaving the lower frequency response flat.

The frequency range of the both low and high pass filters is 20 to 20K with selectable slope
of either 6 or 12 dB per octave.

Bass and Treble shelving
Bass and treble shelving are added to the filter as shown below. Adding the shelving filter
automatically inserts both bass and treble controls. If only a bass or only a treble filter is
required, either bypass the unneeded control or set it to Unused in the selection box.

The corner frequency of the controls can be selected to 0.1 Hz accuracy. Two slopes, 6 and
12dB/octave set how rapidly the frequencies attenuate or boost. The filters can be boost or
cut up to 24dB.
Acoustic Echo Cancellation (AEC)
The AXP50CAT provides one acoustic echo canceller processor for each input. A single
reference is selected for each AEC block. The reference signal input is listed on the Dante
Controller routing view and is selected using Dante Controller.
About AEC
Echo occurs when audio from a talker in the far end is received and amplified into the near
end room of the listener. That sound is then picked up by microphones in the near end
acoustic space and sent back to the far end. The amount of signal sent back to the far end
talker can be substantial. With the added transmission delay, the result is an echo effect that
seriously compromises communication in a teleconference or videoconference.
The AEC processor compares the received signal from the far end (designated as the
“reference”) to the near end mic channel and creates an adaptive filter to cancel the
potential echo before it is sent back to the far end.
AEC Setup
Successful operation of the AEC processing block is a function of proper gain structure and
selection of the AEC reference. This section provides an overview of the two elements.
Proper gain structure involves the relationship between the signal at the selected reference
and the signal at the mic input, within the context of proper levels for the reference and mic
inputs independently. The mic input gain setting is naturally optimized for the voice level of
the talker in that room; therefore the amount of signal from the far end picked up by the mic
is dependent on how much that far end signal is amplified in the near end room and the
distance from the mic to the speakers.
AXP 50 C AT • DSP Configurator – Configuration and Operation 37
Page 44
The reference signal is the signal received from the far end, which is ultimately sent to a
sound reinforcement system within the near end room.
AEC configuration
To insert and configure an AEC processor:
1. Insert an AEC processor on the desired input channel using one of the following
methods:
• Double-click the AEC (filter) block in the DSP Configurator workspace.
• Right-click the AEC block to open the context menu and select Insert AEC.
• Click the AEC block to select it (or use the arrow keys to navigate to the AEC block)
and press <Enter>.
2. Double-click the AEC processor to open it.
3. The AEC reference input is fixed. Use Dante Controller to route the proper signal input.
4. Click Bypass to disengage bypass. The AEC processor is now operational.
AEC dialog
The AEC dialog contains a number of meters and indicators that are essential for setting
up gain structure and monitoring activity. Noise Cancellation, part of the AEC processor,
is selected and adjusted here. A detailed description of the AEC dialog components is
included below.
Activity indicators
• Far – Lights when activity is detected from the remote site.
• Near – Lights when activity is detected from the local site.
• Update – Lights when the AEC is updating, converging, or
reconverging.
Meters
• ERL – Displays the ratio in dB between the signal at the reference
and the signal at the AEC channel input. When ERL is a positive
number, the signal level at the AEC channel input is lower than the
signal at the selected reference (0 to +15dB is desirable).
• ERLE – Displays the amount in dB of potential echo signal that
the AEC algorithm, not including NLP processing (see Non-linear
Processing (NLP) Controls on page39), cancels.
• TER – Displays the sum of ERL + ERLE, in dB.
Reference
The AEC reference input is selected using Dante Controller.
AXP 50 C AT • DSP Configurator – Configuration and Operation 38
Page 45
Noise Cancellation
Noise cancellation is switched on or off from the AEC dialog. The noise canceller detects
steady state noise, such as HVAC or other continuous system noise, and effectively
removes it without causing audible artifacts.
Noise cancellation is engaged or disengaged using a checkbox. When the box is checked,
noise cancellation is engaged, or switched on. When cleared, noise cancellation is
disengaged, or switched off. The default setting is noise cancellation switched on and set to
15dB of noise attenuation.
Up to 20dB of noise cancellation is possible, in 0.1dB increments.
Advanced AEC Controls
Click on the open/collapse icon at the bottom of the AEC dialog to reveal the advanced
AEC controls.
Advanced control functionality is as follows:
Non-linear Processing (NLP) Controls
• Enable NLP – This box is selected by default. NLP is
necessary for the removal of echo.
• NLP Presets – Click Soft, Normal, or Agressive to load
a set of values to the three NLP parameters: Max NLP
Reduction, Attack Time, and Release Time.
The default parameters (shown at right) match the Normal
preset.
• Max NLP Reduction – The maximum possible reduction
in echo artifacts that can be applied. The range is 0.0 to
80.0dB in 0.1 dB increments.
Default is 50.0dB.
• Attack Time – The speed in which NLP is applied. The range is 0.0 to 100.0msec in
0.1 msec increments.
Default is 6.0msec.
• Release Time – The speed in which NLP is released. The range is 1.0 to 3000.0msec
in 0.1 msec increments.
Default is 150.0msec.
Additional controls
• Double Talk Echo Reduction – Sets the amount of echo reduction applied during
double-talk. The range is 0.0 to 20.0dB in 0.1 dB increments.
Default is 15.0dB.
• Comfort Noise – Sets a comfort noise level in dB to eliminate states of complete
silence, which could be perceived as a failed connection. The range is 0.0 to 40.0dB in
0.1 dB increments.
Default is 0.0dB (comfort noise off).
AXP 50 C AT • DSP Configurator – Configuration and Operation 39
Page 46
Basic AEC Configuration
AEC must be configured correctly for optimum performance.
To configure AEC:
1. Optimize the active microphone input gain levels for local voice reinforcement.
2. Insert an AEC block on each microphone input (see Acoustic Echo Cancellation
(AEC) on page37).
3. Open each AEC block and set the reference (preferably the VTC input channel) using
Dante Controller. Click Bypass to disengage bypass and activate AEC.
4. Mix the VTC input to the local room amplifier output, adjusting output volume to a
suitable level.
5. Open the AEC block and ask the person on the far end to begin speaking.
Verify the FAR indicator (see Activity indicators on page38) responds to the voice.
6. Adjust the input level of the reference so the ERL meter indicates between 0 and 15dB.
• If ERL is too high, lower the reference level.
• If ERL is too low, raise the reference level.
7. Do not adjust Noise Cancellation (on by default) or advanced AEC settings. These
settings are optimized for typical installations and generally do not need adjusting.
AEC is now optimized.
Troubleshooting AEC
• Verify you are using the correct reference.
• Are the appropriate signals mixed into the reference?
• If you are using an output as a reference, be certain the output volume has not
been adjusted.
• Check gain staging of the microphones. Be certain you are receiving a strong signal in
the -30 to -20 dB range.
• Check the ERL level. If necessary, readjust with the input reference level.

Dynamics Processor
A dynamics processor alters the dynamic range, the difference between the loudest to the
quietest portions of an audio signal. Each input channel provides two dynamics processor
blocks that, when inserted, provide one of four types; AGC, Compressor, Limiter, or a Noise
Gate processor.
To insert a processor into an empty block, select from the processor menu. Double-click the
block to open the menu, or right-click to open the context menu (see below).
Once a processor is inserted, double-click the processor block to change individual
processor parameters. For comparison, the block can be bypassed by clicking Bypass.
The dialogs contain all parameters are in text boxes with a resolution of 0.1 increments.
Parameters can be set by direct entry in the text box to replace existing text, then press
<Enter>, or <tab>, or <click> to another area. Threshold, gain/attenuation, target, and ratio
parameters have adjustment points on the graph display. Use the mouse to click+drag
the graph point to the desired destination or value. All time values have a horizontal slider
allowing adjustment in 1 ms increments by either a click+drag of the slider handle, or
focusing on the slider, then using left or right arrow keys (the <Page Up> and <Page Down>
keys adjust in increments of 10 ms).
The table below lists each dynamics processor type, parameters, and factory default
settings for the processor.

AGC (Automatic Gain Control)
AGC adjusts the gain level of a signal based on input strength to achieve a more consistent
volume. Below the set threshold, the signal is not affected. Above the threshold, weaker
signals are boosted up to the maximum gain setting to reach a user-defined target level. As
the signal level approaches the target level it receives less gain or no gain at all. Once the
signal level reaches the target level all gain is removed. Click in each field or use the sliders
to change the values.
Threshold — The input level where maximum gain
is applied (after the attack time is exceeded). On the
graph at right follow the red input level from the lower
left to -40dB where the first red circle is. Signal levels
less than -40dB remain at their original levels. Signal
levels at or exceeding -40dB have up to 12dB of
gain applied (Maximum Gain).
The threshold level is adjusted from -80.0 to 0.0dB in
0.1dB increments.
Default is -40.0dB.
Maximum Gain — The highest amplification applied
to a signal exceeding the threshold and up to the
lower limit of the window (see Window below).
Maximum Gain is set from 0.0dB to +60dB in
0.1dB increments.
Default is 12.0dB.
Target — The desired average signal level of the
output when AGC is applied. AGC can vary the gain
according to the input signal level, specified target
level and maximum gain. As the signal approaches
the target level of – 10dB, gain is reduced until at
– 10dB, gain is no longer applied.
The target level is adjusted from -40dB to 0.0dB in
0.1dB increments.
Default is – 10.0dB.
Window — Indicated by two yellow lines, is a specified range above and below the target
level. Below the lower line maximum gain is always applied to the signal. When the signal
reaches the window, gain control begins scaling in a linear fashion to achieve smoother
results as the signal reaches the target level.
The window range is set in 0.1dB increments from 0.0dB to 20.0dB.
The default threshold is – 40dB. The default target level is – 10.0dB. The default window
range is 12.0dB.
Attack Time — Adjusts the time delay for AGC to engage after the input signal level
reaches or exceeds the threshold level.
Attack time is adjusted from 0.0 to 3000.0 ms in 0.1ms increments.
Default is 500.0 ms.
Hold Time — Adjusts how long AGC continues to boost the signal after the input signal
drops below the threshold and before release time begins.
Hold time is adjusted from 0.0 to 3000.0ms in 0.1 ms increments.
Default is 0.0 ms.
Release Time — Adjusts the time it takes to return the signal to normal (unprocessed)
levels after the signal no longer exceeds the threshold level setting. Release time begins only
after hold time is reached.
Release time is adjusted from 10.0 to 10000.0 ms in 0.1ms increments.
Default is 1500.0 ms.

Compressor
The compressor regulates signal level by reducing the dynamic range of the input signal
above a specified threshold. The input level to output level ratio determines the reduction in
the dynamic range beyond the threshold setting. For example, in the diagram below, with
a ratio setting of 2:1, for every 2dB of input above the threshold, the compressor outputs
1dB.
Compression is commonly used to contain mic levels within an acceptable range for
maximum vocal clarity. A compressor can make softer sounds louder in one of two ways.
The dynamic range can be reduced by compressing the signal above the threshold while
raising the post-compressor gain/trim (referred to as “make-up gain”). Alternately, the
input signal can be increased while the compression ratio above the threshold is increased
correspondingly to prevent clipping. Both techniques have the effect of making louder
portions of a signal softer while at the same time increasing softer signals to raise them
further above the noise floor.
Compression can also protect a system or a signal chain from overload similar to a limiter.
Threshold — The input signal level above which compression begins (subject to attack
time) and below which compression stops
(subject to hold and release time).
Threshold level is adjusted from -80.0 to 0.0 dB in
0.1 dB increments.
Default is -30.0 dB.
Ratio — The input signal level reduction when
compression is engaged.
Ratio is adjusted from 1.0 to 100.0 in 0.1
increments.
Default is 2.0:1.
Attack Time — Adjusts the time delay for
compression to engage after the input signal level
reaches or exceeds the threshold level. Attack
time is adjusted from 0.0 to 200.0 ms in 0.1ms
increments.
Default is 5.0 ms.
Hold Time — Adjusts how long signal level
reduction continues after the input signal drops
below the threshold and before release time
begins.
Hold time is adjusted from 0.0 to 3000.0ms in
0.1 ms increments.
Default is 100.0 ms.
Release Time — Adjusts the time it takes to
return the signal to normal (unprocessed) levels after the signal no longer exceeds the
threshold level setting. Release time begins only after hold time is reached. Release time is
adjusted from 10 to 1000.0 ms in
0.1 ms increments.
Default is 100.0 ms.
Soft Knee — Click the Soft Knee check box to smooth and soften the transition from
uncompressed to compressed output levels. There are no adjustments.
AXP 50 C AT • DSP Configurator – Configuration and Operation 43
Page 50
Limiter
The limiter restricts the input signal level by compressing its dynamic range above a
specified threshold. The limiter is most commonly used to prevent clipping, protecting a
system against component or speaker damage. While the limiter is closely related to the
compressor, it applies a much higher compression ratio of ∞:1. The ratio is fixed and cannot
be changed.
Threshold — The input signal level above which
limiting begins (subject to attack time) and below
which compression stops (subject to hold and
release time). Threshold level is adjusted from
-80.0 to 0.0 dB in 0.1 dB increments.
Default is -10.0 dB.
Attack Time — Adjusts the time delay for
limiting to engage after the input signal level
reaches or exceeds the threshold level. Attack
time is adjusted from 0.0 to 200.0 ms in 0.1ms
increments.
Default is 2.0 ms.
Hold Time — Adjusts how long signal level
reduction continues after the input signal drops
below the threshold and before release time
begins.
Hold time is adjusted from 0.0 to 3000.0ms in
0.1 ms increments.
Default is 50.0 ms.
Release Time — Adjusts the time it takes to
return the signal to normal (unprocessed) levels
after the signal no longer exceeds the threshold
level setting. Release time begins only after hold
time is reached. Release time is adjusted from
10 to 1000.0 ms in 0.1 ms increments.
Default is 50.0 ms.
Soft Knee — Click the Soft Knee check box to smooth and soften the transition from
uncompressed to compressed output levels. There are no adjustments.

Page 51
Noise Gate
The noise gate allows an input signal to pass
only when it exceeds a specified threshold level.
Above the threshold level, the signal passes
unprocessed; below the threshold the signal is
attenuated at the rate set by the ratio adjustment.
The typical setting of the noise gate threshold is
just above the noise level of the environment or
source equipment. That allows signals above the
noise to pass, and attenuates the noise when
there is no signal to eliminate background noise.
Click in each field or use the sliders to change the
values.
Threshold — The input signal level below which
attenuation (gating) begins (subject to attack time)
and above which gating stops (subject to hold and
release time).
The threshold level is adjusted from -80.0 to
0.0dB in 0.1dB increments.
Default is -65.0dB.
Max Attenuation — The maximum attenuation of
the signal when it drops below the threshold.
Maximum attenuation is adjusted from 0.0 to
80.0dB in 0.1dB increments.
Default is 25.0dB.
Ratio — is the input signal level reduction when
gating is engaged.
The ratio is adjusted from 1.0 to 100.0 in 0.1 increments.
Default is 20.0:1.
Attack Time — The time delay for gating to engage after the input signal level drops below
the threshold level.
Attack time is adjusted from 0.0 to 200.0 ms in 0.1ms increments.
Default is 1.0 ms.
Hold Time — Adjusts how long gating continues after the input signal drops below the
threshold. If the signal is still below the threshold when hold time ends, release time begins.
Hold time can be adjusted from 0.0 to 500.0ms in 0.1 ms increments.
Default is 300.0 ms.
Release Time — Adjusts the time it takes to return the signal to normal (unprocessed)
levels after the signal is no longer below the threshold level setting. Release time begins only
after hold time is reached.
Release time can be adjusted from 10 to 1000.0 ms in 0.1 ms increments.
Default is 1000.0 ms.

Output Gain (GAIN)
e
The post-processor gain control provides gain or attenuation
after the input processing signal chain. It includes a mono
long-throw fader with – 100.0 to +12.0dB gain range,
and a current level setting readout below the fader. Fader
adjustments are in 1dB increments. Adjustments can be
entered manually to 0.1dB resolution.
Default is unmuted at unity (0.0dB) gain.
Selecting the fader handle with the mouse or clicking within
the fader area brings focus to the fader. The input signal level
is adjusted using any of the following methods:
• <Click + hold> the fader handle, then drag it to desired
level in 1.0dB steps.
• Select or <tab> to the fader handle, then use the
<up/down arrows> to set the desired level in 1dB steps.
<Page Up> increases and <Page Down> decreases the
level in 5dB steps.
• Click in or <tab> to the level readout field. Type a new value, then press <Enter> or
<tab> to another area.

The digital I/O provides external triggering for events such as mic activation and muting, and
for illuminating status LEDs based on the input. It accepts logic level signals and outputs
logic level. It can either toggle the output between high and low at each input trigger, or hold
the output high or low until another input trigger is received.
To access the Digital I/O control, from the toolbar select Tools>Configure Digital
Inputs.

A drop-down list for each input selects the digital I/O configuration option for that input.
Select an option from the drop-down list. An input is muted in the following ways:
Level Trigger - Low Mutes – A logic low signal (< 1 VDC) mutes the input. As long as the
digital input remains low, the associated mic/line input is muted. When it goes hi, the input is
unmuted.
Level Trigger - Hi Mutes – A logic high signal (> 5 VDC) mutes the input. As long as the
digital input remains high, the associated mic/line input is muted. A digital low unmutes the
input.
Edge Trigger - Hi to Lo Mutes, Lo to Hi Unmutes – The associated mic/line input mutes
during a digital input transition from high to low and unmutes during a transition from low to
high.
Edge Trigger - Lo to Hi Mutes, Hi to Lo Unmutes – The associated mic/line input mutes
during a digital input transition from low to high and unmutes during a transition from high to
low.
Toggle Trigger - Hi to Lo Toggles Mute/Unmute – A logic signal change from high to
low toggles the corresponding input from mute to unmute, or unmute to mute.
Toggle Trigger - Lo to Hi Toggles Mute/Unmute – A logic signal change from low to
high toggles the corresponding input from mute to unmute, or unmute to mute.

Figure 24. Digital I/O Connections
In this example, a microphone is connected to input 1. The control Digital I/O is connected
to a momentary switch that mutes and unmutes the microphone and also to two status
indicators to tell users the microphone is live (green-unmuted) or muted (red).
The digital I/O interface for input 1 is set as follows:
Level - Hi – With the switch open, the input sees a logic high. As long as the digital input
remains high, the associated mic/line input is muted.
Closing the switch connects the input to ground and the logic level goes low. A digital lo
unmutes the input so the user can talk.
The corresponding digital output connections are:
O1 - Mute Hi – When the input signal is muted, O1 is switched high turning on the red LED
indicator. O2 is low during mute so the green LED remains off.
O2 - Unmute Hi – When the input signal is unmuted, O2 is switched high turning on the
green LED indicator. At the same time, the unmuted input condition switches O1 low,
turning off the red LED.
Various combinations of input and output logic in this manner can accomplish a great
number of configurations.

Dante Configuration
and Operation
This section describes the AXP50CAT network installation, configuration, and control
using Dante Controller for Windows and includes:
• AXP50AT Bus
• Creating a Physical Dante Network
• Dante Controller Configuration
• Selecting Inputs and Outputs for Dante
• Signal Routing with Dante
• Dante Troubleshooting
AXP50AT Bus
AXP50CAT devices are equipped with an AT bus and use Dante technology to provide
high performance digital audio networking over standard TCP/IP networks. Dante allows
audio channels to be transported across a switched Ethernet data network while meeting
the quality requirements of professional audio.
Audio signals are converted by the AXP50CAT models, processed, then routed to the AT
bus for availablity over the network. The audio network can be shared with control traffic or
unrelated data traffic. Audio channels can be unicast or multicast to make the best use of
available bandwidth.
The AXP50CAT models are both a transmitter (source), and receiver (destination) for
signals on a Dante network. Transmitters and receivers can be located anywhere on the
Ethernet network and can be relocated without reconfiguring the AXP50CAT or the
network.
To connect a control device or telnet software such as DataViewer to the AXP50CAT,
you must use Dante Controller to locate the IP address (see To Establish a Network
Connection on page67).
AXP50CAT • Dante Configuration and Operation 56
Page 63
Creating a Physical Dante Network
MIC/LINE INPUT
Basic Configuration
A physical network is required to share Dante audio channels between an AXP50CAT and
DMP128AT devices. Each AXP50CAT 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 AXP50CAT-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 topology has one DMP128CAT as the central unit, which is then directly
connected to up to three AXP50CATs. Alternatively, a larger network switch can be used
in place of the central DMP128CAT, allowing more than three AXP50CATs connected in
the star configuration (see figure 27).

Figure 28. 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 AXP50CAT 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...), 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...).
Managing Network Traffic
Because Dante devices prefer to use multi-cast routing to distribute audio channels, it is
recommended that, if possible, the audio network be kept separate from the local business
network. For more information on strategies to manage audio network traffic in an integrated
system, refer to the Dante Controller manual (Multicast Transmit Flow Configuration) at the
Audinate website.
AXP50CAT • Dante Configuration and Operation 57
Page 64
Dante Controller Operation
The 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 AXP50CAT is the model number followed by the last six digits of the MAC address
(Example: AXP50 - 063f70).
Multiple devices on the same network can present difficulty identifying inputs and outputs.
To avoid confusion, each device must be renamed to a unique identifier (see Rename
Connected AXP50CAT Devices on page14).
NOTE: To simplify renaming, connect only one Dante device to the network at a time.
As each device is renamed, it can remain connected.

If the network has a DHCP server, it receives its IP configuration using the standard DHCP
protocol. On a network without a DHCP server, a Dante-enabled device automatically
assigns itself an address using link local protocol.
Once connected, Dante Controller begins auto-discovery of all Dante devices. While
scanning the network, it also advertises itself to allow Dante-enabled devices to see and
communicate with it.

Receivers, representing Dante device inputs, are on the left side running vertically.
Transmitters, representing Dante device outputs, are along the top running horizontally. The
connection points form a large matrix in the center of the screen.
The name shown in the receivers column is extracted from the Dante interface of
the connected device. The AXP50CAT inputs are Dante receivers and labelled
DIGITAL_In‑01 to DIGITAL_In‑05 (or the maximum available from a connected device).
In addition there are five reference signal inputs, REFERENCE‑01 to REFERENCE‑05. The
output names are labelled from PRE‑OUT‑01 to PRE‑OUT‑05 to mirror the AXP50CAT
pre-processing outputs and, and from OUTPUT‑01 to OUTPUT‑05 corresponding to the
AXP50CAT outputs.
Dante provides a way to rename the connected device and to re-label each input and
output (see Rename an Input or Output on page61). Avoid confusing device names
and inputs and outputs during operation. If necessary, rename the device and inputs and
outputs before proceeding.
Dante Controller Naming Conventions:
• Device labels follow Domain Name System (DNS) hostname rules. Legal
characters are A‑Z, a‑z, 0‑9, and dash or hyphen (-). Device labels must begin

• Dante Tx and Rx labels can be up to 30 characters in length. Label comparisons
are not case-sensitive; “OUTPUT01” and “OUTPUT01” are recognized as the same
connection. Unicode and non-roman characters are not supported.
• Tx channel labels can use any character except equals (=), period (.), or ‘@’.
• Tx channel labels must be unique on a device but do not need to be unique on
the network.
• Rx channel labels follow the same rules as Tx channel labels.

Dante Network Organization
Dante network connection points can quickly become unmanageable in large systems. To
better organize the various inputs and outputs, it is recommended you name each input and
each output using descriptions of the device they belong to, the location of the device, or
the purpose of the input or output.
Rename an Input or Output
To simplify setup and operation of large matrix systems, rename the input (receiver) and
output (transmitter) lines to better indicate the input a source device is connected to and the
output a receiver is connected to.

Dante Controller is used for all network level signal routing of AT bus inputs and outputs.
The digital input and output channels of the AXP50CAT are shown in Dante Controller
as transmitters and receivers. The digital inputs, pre-processing, and line outputs are all
available in Dante Controller for routing to other Dante devices.
AXP50CAT Inputs and Outputs
Two sections provide output signals on the AT bus as Dante transmitter channels (see
figure32, G, and H). All AXP50CAT outputs appear to Dante Controller as transmitters.
Audio from these outputs is always available to Dante compatible devices on the same
network.
Two sections receive input signals from Dante network transmitters: the digital inputs and
the AEC reference inputs (see figure32, A, and E-AEC).

Figure 32. DSP Configurator Outputs (Dante Transmitter Channels)
The AXP50CAT inputs (A) can be switched from digital to analog input mode. In analog
input mode, the analog signals on the rear panel inputs are converted to digital before the
gain stage. In digital mode (see Input Channels on page31) the inputs are receiver
channels on the Dante network. The inputs are always available to Dante compatible
devices on the same network. Unless renamed, the five digital inputs are in the Dante
receiver list as DIGITAL_IN‑01 to DIGITAL_IN‑05.
In addition, an AEC reference can be selected from any Dante device transmitter (outputs).
If they have not been renamed, the five AEC reference inputs are listed as Dante receivers
REFERENCE‑01 to REFERENCE‑05 corresponding to the five input channels.
All AXP50CAT outputs (G and H) are listed as transmitters in Dante Controller. Audio
from these outputs is always available to Dante compatible devices on the same network.
Unless renamed, the five pre-processor outputs (G) are in the Dante transmitter list
as PRE‑OUT‑01 to PRE‑OUT‑05). The AXP50CAT output lines (H) are listed in Dante
controller as transmitters (OUTPUT‑01 throughOUTPUT‑05).
Both pre-processor and line outputs (Dante transmitters) can be connected to any Dante
device receiver.

Figure 33. Dante Routing View
There are several icons used to communicate the status of both the transmitter and receiver
channels and the connections (subscriptions).
Icon Description
Indicates an active connection (subscription)
Indicates a pending connection
Indicates a broken connection (subscription)
Indicates the transmitting device has been removed from
the network, or is switched off
The transmitters along the top, and receivers down the side form a matrix on the screen
whose intersection is the connection point between the two. Click once at this intersection
to make the connection. Click again to break the connection.
See the Dante Controller Manual at the Audinate website for additional information.
NOTE: After making changes to Dante network routing such as connections
(subscriptions), device names, or channel labels, wait at least 5 seconds before
disconnecting or powering down the devices. This ensures the new information is
properly saved to those devices. Device level configuration such as sample rates,
latency, and clock settings are saved instantly

Page 71
Dante Troubleshooting
The most common Dante troubleshooting issues occur when no devices are discovered by
the Dante Controller software, or routing is not successful or is prevented. Both issues occur
when software is not able to properly discover devices operating on the Dante network.
Before moving into more difficult troubleshooting, shut down Dante Controller and re-seat
the Ethernet cable connecting the PC to the Dante network. Restart the Dante Controller
software. This can be enough for the software to re-acquire the Dante network.
Simplied Network troubleshooting
If further troubleshooting of Dante discovery is necessary, begin by simplifying the network:
1. Bypass network switches by connecting two Dante compatible units such as an
AXP50CAT and a DMP128AT via their AT ports.
2. Connect the PC to an unused AT port on either device.
3. Use Dante Controller to see if simplifying the network connections resolved the issue
before moving on to the network interface troubleshooting.
4. If the issue is resolved, add connections and hardware one at a time, checking for
proper operation after each addition, until the point of failure is discovered (typically a
bad cable or invalid redundant configuration).
Network Interface troubleshooting
If the issue is still present after simplifying the network, continue to diagnose the PC network
connections.
Check Dante Controller after each step to see if the problem is resolved:
1. Open the Configure Dante Interface dialog from the icon on the opening screen of
Dante Controller (see Start Dante Controller on page59). Be certain the correct
LAN connection is selected (the PC LAN port physically connected to the AT network)
and note the IP address.
2. If it is on, turn off the PC wireless adapter. Disable all connections except the LAN
port connected to the Dante network (verify this is the correct port by checking the IP
address shown in step 1 above).
3. Turn off all anti-virus and firewall software on the PC.
4. Enable DHCP on the remaining network connection. This forces the PC to acquire an IP
address from the Dante interface.
Restart Dante Controller
If connections or normal operation cannot be restored, Dante Controller provides a way to
restart the controller and the software. See the Dante Help files for more information.

Communication and
Control
This section describes SIS programming and control of the AXP50CAT, including:
• Connection Options
• Command/Response Table Overview
• Command/Response Table for Basic SIS Commands
• Command/Response Tables for DSP SIS Commands
Connection Options
The AXP50CAT Audio Expansion Processor can be remotely connected via a host
computer or other device (such as a control system) connected via any AT port.
The AXP50CAT also provides basic set up and control using the Extron SIS
(Simple Instruction Set) commands or DSPConfigurator software. For information on
DSPConfigurator, see DSP ConfiguratorConfiguration and Operation on page20.
SIS commands can be executed using the Extron Electronics DataViewer program, which
can be found on the website.
Any rear panel AT connector can be connected to an Ethernet LAN or WAN.
Communication between the device and the controlling device is via a TCP socket using
port 4333 (see To Establish a Network Connection on page67). This connection
makes SIS control of the device possible using a computer connected to the same LAN or
WAN.
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application (see figure 34).
• Crossover cable — Direct connection between the computer and the AXP50CAT.
• Patch (straight) cable — Connection of the AXP50CAT to an Ethernet LAN.

AXP50CAT • Remote Communication and Control 66
Page 73
To Establish a Network Connection
To establish a network connection with the AXP50CAT, the control device must be
connected to the same network. Communication between the AXP50CAT and a
controlling device or software such as DataViewer is via the device IP address using port
4333. Dante Controller displays the current IP address of the device.
To find the IP address of a Dante device, the name of the device must be known.
1. Open Dante Controller for Windows
2. From the toolbar, select Device>Device View.
The Dante Controller - Device View dialog opens.
3. Select your device from the (Select a Dante Device...) drop-down list.
4. Click the Network Config tab to open the network configuration page.

AXP50CAT responds with a copyright message, the name of the product, firmware
version, and part number (see below).
The device is ready to accept SIS commands immediately after it sends the copyright
message.
AXP50CAT-initiated Messages
The AXP50CAT initiates messages under specific conditions. No response is required
from the host. The AXP50CAT-initiated messages are listed here (underlined).
© Copyright 2014, Extron Electronics, AXP50CAT, Vn.nn, 60‑1325‑01
Vn.nn is the firmware version number.
The AXP50CAT sends the boot and copyright messages under the following
circumstance:
If the AXP50CAT is off and DataViewer is set up and running (the PC is cabled to the
AXP50CAT), the connected unit sends these messages when first powered on.
Using the Command/Response Tables
SIS commands consist of a string (one or more characters per command field). No special
characters are required to begin or end a command sequence. When the AXP50CAT
determines a command is valid, it executes the command and sends a response to the host
device. All responses end with a carriage return and a line feed (CR/LF = ]), signaling the
end of the response character string.
When programming, certain characters are more conveniently represented by their
hexadecimal rather than ASCII values. The following table shows the hexadecimal
equivalent of each ASCII character:
Figure 35. ASCII to Hex Conversion Table

Error Responses
When the AXP50CAT is unable to execute the command, it returns an error response to
the host. The error response codes and their descriptions are as follows:

Command/Response Table Overview
Although the AXP50CAT uses the same structure for SIS commands, there are two
variations. One is the global command structure documented in the
Command/Response Table for Basic SIS Commands that follows.
The second set of tables for DSP SIS commands uses the command structure outline
beginning with Command/Response Tables for DSP SIS Commands on page71.
While using the same structure of basic SIS commands, they differ in how the software
addresses the individual processor blocks within the AXPCAT.

Digital signal processor (DSP) gain and mute can be controlled using SIS commands.
These commands follow the same general rules as basic SIS commands, but variables (X/)
tend to be more complex. Also, a comprehensive understanding of the audio signal flow
is helpful in understanding the commands. The following diagram shows the specific DSP
processors available for SIS commands.
NOTE: The entire signal flow is described in more detail in the section,

Figure 36. DSP Processors Addressable via SIS Commands
The DSP Configurator program window consists of five channels. Each channel consists of
an input gain and filter, a pre-processing output, the processors, and an output gain. The
following gain controls and processors can be controlled using DSP SIS commands:
Mic/Line input gain control – provides level adjustment and mute for each channel.
A
Output gain control – Provides level control and mute for each channel.
B
DSP control commands are an extension to SIS commands. They differ only in their data
string and the requirement to send each command with an “AU” suffix.
The complete structure for the DSP SIS commands is:

MountingtheAXP50CAT
The AXP50CAT can be mounted in the following ways:
• Set on a table,
• Mounted on a rack shelf,
• Mounted under a desk or tabletop.
The half rack width, 9.5 inch (24.1cm) 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.
Tabletop Use
Each AXP50CAT is supplied 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
AXP50CAT in a rack.
1. Elevated operating ambient temperature — If the equipment is 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 (such as the use of power strips).

Table or Wall Mounting
Under Desk
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.
Mount the AXP50CAT to a table or wall as follows:
1. Remove the rack mounting brackets and attach the MBU 149 brackets in their place.
2. 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.
3. 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.
4. 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.
5. Align the mounting screws with the slots in the brackets and place the unit against the
surface, with the screws through the bracket slots.
6. Slide the unit slightly forward or back, then tighten all four screws to secure it in place.
