About this Guide
This guide contains installation, configuration, and operation information for the Extron
Electronics AXI 22 AT and AXI 44 AT audio expansion interfaces. In this guide, the terms
“AXI devices,” “device,” and “AXI” are all used to refer to the AXI 22 AT and AXI 44 AT
interchangeably.
About the AXI 22 AT and AXI 44 AT
The AXI 22 AT and AXI 44 AT audio expansion interfaces are analog-to-Dante/Dante-to-
analog converters in 1U high, quarter rack width enclosures. The AXI 22 AT is a two input,
two output interface and the AXI 44 AT is a four input, four output interface. The inputs
for both devices include preamps with 48 V phantom power and accept 3.5 mm captive
screw connectors. The Dante port on the rear panel of each device provides 2x2 and 4x4
Dante interfacing respectively. Gain and phantom power settings are software controlled
and can be made from the front panel, DSP Configurator Software, or SIS commands
via DataViewer. The AXI will appear on the Dante network and use the Dante Controller
software for routing, device naming, channel naming, transmission latency, sample rate,
and IP communication settings. The AXI 22 AT and AXI 44 AT are pure break-in/break-out
devices that contain no DSP processing.

AXI 22 AT and AXI 44 AT • Introduction 2
Features
• Two or four mic/line inputs transmit audio to a Dante™ network — Two
(AXI22AT) or four (AXI 44 AT) mic/line inputs include selectable 48 volt phantom
power for balanced or unbalanced sources and accept 3.5 mm 6-pole captive screw
connectors. A rotary detented knob is available for gain control.
• Two or four line level outputs receive audio from a Dante network —Two
(AXI22AT) or four (AXI 44 AT) channels of high quality digital audio can be routed from
local or remote systems via Dante and converted to balanced or unbalanced line level
analog audio and output with 3.5 mm 6-pole captive screw connectors.
• Input select, gain, and phantom power controls located on front panel and
configurable through DSP Configurator Software — Settings can be modified
from the front panel, DSP Configurator Software, or SIS commands via DataViewer.
• Dante audio networking provides a wide range of expansion options — Dante-
equipped audio products, including the AXI 22 AT and AXI 44 AT, provide scalability
for creating larger audio systems over a local area network using standard Internet
protocols.
• Studio grade 24-bit analog-to-digital and digital-to-analog converters with
selectable sampling rates up to 96 kHz — Professional converters fully preserve the
integrity of the original audio signal, with selectable sampling rates via Dante Controller.
• Power over Ethernet allows the AXI 22 AT and AXI 44 AT to receive power over
a single Ethernet cable, eliminating the need for a local power supply.
• 1U, quarter rack width metal enclosure — Compact, durable enclosure can be
discreetly installed under a desk, in a lectern, in millwork, or in an AV equipment rack.
• Highly reliable, energy-efficient external universal power supply (optional).

Installation and Operation
This section describes the AXI 22 AT and AXI 44 AT rear panel connections and front panel
controls. The following topics are covered:
• Mounting
• Rear Panel Connections
• Front Panel Controls
• Reset Modes
Mounting
The 1U high, quarter rack width, 6 inch deep AXI 22 AT and AXI 44 AT devices mount in the
following manners:
• Rack mounting — Attach the device to a standard 19 inch rack shelf. The following
Underwriters Laboratories (UL) guidelines pertain to the installation of the AXI 22 AT and
AXI 44 AT devices in a rack:
• Reduced air flow — Install the equipment in the rack so that the amount of air
flow required for safe operation of the equipment is not compromised.
• Mechanical loading — Mount the equipment in the racks so that uneven
mechanical loading does not create a hazardous condition.
• Circuit overloading — When connecting the equipment to the supply circuit,
consider the effect that circuit overloading might have on overcurrent protection
and supply wiring. Consider equipment nameplate ratings when addressing this
concern.
• Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to power supply connections other than direct
connections to the branch circuit (such as the use of power strips).
• Under-furniture mounting — Mount the AXI 22 AT or AXI 44 AT under the surface of
a desk, table, or podium.
• Free-standing — Attach the four rubber feet provided with the device to the bottom of
the AXI 22 AT or AXI 44 AT in the four corners and place the unit on furniture as desired.

AXI 22 AT and AXI 44 AT • Installation and Operation 6
ATTENTION:
• Always use a power supply provided by or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and
may cause damage to the supply and the end product.
• Utilisez toujours une source d’alimentation fournie ou recommandée par
Extron. L’utilisation d’une source d’alimentation non autorisée annule toute
conformité réglementaire et peut endommager la source d’alimentation ainsi
que le produit final.
• If not provided with a power supply, this product is intended to be supplied
by a UL Listed power source marked “Class 2” or “LPS” and rated output
12Vdc 0.5 A minimum (for AXI 22 AT) or 12Vdc 0.6 A minimum (for AXI 44
AT), or 48 VDC (PoE), minimum 0.35 A.
• Si ce produit n’est pas fourni avec une alimentation, il doit être utilisé avec
une source d’alimentation certifiée UL de classe 2 ou LPS avec une tension
nominale 12 Vcc, 0,5 A minimum (pour l’AXI 22 AT) ou 12 Vcc, 0,6 A
minimum (pour l’AXI 44 AT), ou 48 Vcc (PoE), 0,35 A minimum.
• Extron power supplies are certified to UL/CSA 60950-1 and are classified as
LPS (Limited Power Source). Use of a non-LPS or unlisted power supply will
void all regulatory compliance certification.
• Les sources d’alimentation Extron sont qualifiées UL/CSA60950-1 et
sont classéesLPS(LimitedPowerSource). L’utilisation d’une source
d’alimentation non-listée ou non-listéeLPS annulera toute certification de
conformité réglementaire.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities. The power supply is to be located within
the same vicinity as the Extron AV processing equipment in an ordinary
location, Pollution Degree 2, secured to the equipment rack within the
dedicated closet, podium, or desk.
• Sauf mention contraire, les adaptateurs AC/DC ne sont pas appropriés pour
une utilisation dans les espaces d’aération ou dans les cavités murales.
La source d’alimentation doit être située à proximité de l’équipement
de traitement audiovisuel dans un endroit ordinaire, avec un degré2 de
pollution, fixé à un équipement de rack à l’intérieur d’un placard, d’une

similar structure.
• La source d’alimentation ne devra pas être fixée de façon permanente à une
structure de bâtiment ou à une structure similaire.

AXI 22 AT and AXI 44 AT • Installation and Operation 7
• The length of the exposed wires in the stripping process is critical. The ideal
length is 3/16 inches (5 mm). If the wires are any longer, the exposed wires
may touch, causing a short circuit between them. If they are any shorter, the
wires can be easily pulled out even if tightly fastened by the captive screws.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend de
les dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont un peu
plus longs, les câbles exposés pourraient se toucher et provoquer un court
circuit. S’ils sont un peu plus courts, ils pourraient sortir, même s’ils sont
attachés par les vis captives.
NOTE: Do not tin the wires. Tinned wire does not hold its shape and can become
loose over time.
BMic/Line Inputs — Connect two mono balanced or unbalanced microphone or line
level sources (AXI 22 AT) or four mono balanced or unbalanced microphone or line level
sources (AXI 44 AT) using 6-pole 3.5mm captive screw input connectors (see 3-pole
Audio Input Wiring in figure5). Phantom power is available on all inputs.
Instead of two or four mono sources, one balanced or unbalanced stereo signal
(AXI22AT) or two balanced or unbalanced stereo sources (AXI 44 AT) can be
connected using 6-pole captive screw connectors (see 6-pole Audio Input Wiring in
figure5).

the selected input, from no signal to -60 dBFS (first LED lit) up to 0 dBFS (all LEDs lit).
When the gain rotary encoder is rotated, the LED stack changes to display the input
gain level of the selected input. Input gain level continues to display for 2 seconds after
adjustment of the rotary encoder ceases. After this 2 second period, the LED stack
displays the input signal level.
The dB scale to the left of the LEDs indicates input gain level from 0 dB to +42dB.
Each LED represents 6 dB of gain, while gain adjustments are made in 3 dB steps.
The LED will blink to indicate a 3 dB change in level, and light solid to indicate a 6 dB
change. The entire LED stack flashes to indicate the input is muted.
FGain Rotary Encoder — The rotary encoder adjusts the input gain for the currently
selected input, from 0 dB to +42 dB in 3 dB steps. Use a small flat head screwdriver,
such as the provided Extron Tweeker, to turn the encoder clockwise to raise the gain
and counter-clockwise to lower the gain.
GPhantom Power Switch — This momentary switch turns +48 V phantom power on
or off for the currently selected input. Use a small flat head screwdriver, such as the
provided Extron Tweeker to adjust the phantom power switch. Push the switch up
to turn phantom power on and down to turn it off. The switch is neutral in the middle
position (default).
HPhantom Power Indicator LEDs —These green LEDs light steadily to indicate which
channels have phantom power applied.
IInput and Output Signal and Clip LEDs — The green signal LEDs light steadily
when signal is present and increase in intensity from -60dBFS (lowest intensity, signal
presence indication) to -1 dBFS (full brightness). The red clip LEDs light steadily at
-1dBFS to indicate clipping and stay lit for one second beyond receiving the clip
message.
Reset Modes
Pressing the rear panel reset button (see figure3,Eon page5) with a stylus or
Extron Tweeker will reset only the Dante module in the AXI, leaving the gain and phantom
power settings unaffected (see Command and Response Table for SIS Commands on
page32 for information resetting gain and phantom power). There are two reset modes
activated with the rear panel reset button.
Reset Mode 1
Press the rear panel reset button and quickly release it to cause a hardware reset of the
Dante module while preserving all of its settings such as IP configuration, routing, device
name, channel names, and sampling rate.
Reset Mode 2
To cause an absolute system reset of the Dante module back to factory default conditions,
press and hold the rear panel reset button for 10 seconds until the AT (PoE) port LEDs flash.
Following this reset, the Dante module will proceed to its normal boot sequence. This reset
will:
• Set the IP configuration to default settings
• Clear all audio channel routing
• Set the Dante device name and channel names to default
