Introduction

This section provides an overview of this guide and the features of the Extron AXI 22 AT and
AXI 44 AT audio expansion interfaces. This section covers the following topics:

• About this Guide

• About the AXI 22 AT and AXI 44 AT

• Features

• Applications Diagrams

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-to­analog 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 1

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).

AXI 22 AT and AXI 44 AT • Introduction 3

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.

NOTE: To mount the AXI 22 AT or AXI 44 AT using an Extron mounting kit, see the

instructions provided with the kit.

dans un endroit ordinaire, avec un degré2 de pollution, fixé à un équipement de
rack à l’intérieur d’un placard, d’une estrade, ou d’un bureau.

• The installation must always be in accordance with the applicable provisions of

National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16.

• Cette installation doit toujours être en accord avec les mesures qui s’applique

au National Electrical Code ANSI/NFPA70, article725, et au Canadian Electrical
Code, partie1, section16.

• The power supply shall not be permanently fixed to building structure or similar

structure.

• La source d’alimentation ne devra pas être fixée de façon permanente à une

structure de bâtiment ou à une structure similaire.

• 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.

Power LED Indicator — This green LED blinks while the unit is powering on and lights

A

steadily when the unit is ready for use.

USB Config Port — Connect a computer to this USB Mini-B port for device

B

configuration.

Input Selector Button — Press this button to cycle through the device inputs. Select

C

an input to adjust gain, set phantom power, and read input levels for that input.

Input Indicator LEDs — These LEDs light to indicate which input is currently selected.

D

Gain and phantom power adjustments are only applied to the currently selected input.

Input Level and Gain LED Stack — The LED stack displays the input signal level of

E

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.

Gain Rotary Encoder — The rotary encoder adjusts the input gain for the currently

F

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.

Phantom Power Switch — This momentary switch turns +48 V phantom power on

G

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).

Phantom Power Indicator LEDs —These green LEDs light steadily to indicate which

H

channels have phantom power applied.
