AXI 016 • Setup Guide
This guide provides basic instructions for an experienced technician to install the AXI 016 Audio Expansion Interface. The AXI016
is a pure breakout device that provides 16 line-level outputs for EXP-enabled devices. The AXI016 is simple to use with no DSP
processing hardware controls. For additional information and specications, go to www.extron.com.
NOTES:
• EXP-enabled devices are devices that contain an Extron EXP port for routing 16 bidirectional channels of digital audio.
• In this guide, “EXP-enabled devices” and “EXP devices” are used interchangeably.
Disconnect Power and Mount the AXI 016
Disconnect power from the AXI 016 and power off all devices that will be connected to it. The AXI 016 is housed in a half-rack
width, 6-inch deep, 1U-high metal enclosure that can be rack mounted, set on a rack shelf, or placed on a table with the provided
rubber feet. Select a suitable mounting location, then choose an appropriate mounting option.

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 par Extron. L’utilisation d’une source d’alimentation non autorisée
annule toute conformité réglementaire et peut endommager la source d’alimentation ainsi que l’unité.

ATTENTION:
• 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, 0.4 A minimum, 48 or 56 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, 0,4 A minimum (PoE), 48 Vcc (PoE), or 56 Vcc (PoE)
0,35Aminimum.
• 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 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. The power supply shall not be permanently fixed to
building structure or similar structure.
• 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. La source d’alimentation ne devra pas
être fixée de façon permanente à une structure de bâtiment ou à une structure similaire.
BAnalog Audio Outputs — Use 6-pole, 3.5 mm captive screw connectors to connect up to 16 balanced or
unbalanced line-level devices. Balanced or unbalanced mono devices can also be connected using 3-pole, 3.5 mm
captive screw connectors.

ATTENTION :
• For unbalanced audio outputs, connect the sleeves to the ground contact. DO NOT connect the sleeves to the
negative (-) contacts.
• Pour l’audio asymétrique, connectez les manchons au contact au sol. NE PAS connecter les manchons aux
contacts négatifs (–).
CEXP Input Port and LED — This RJ-45 EXP port connects the AXI 016 to the EXP port of a primary EXP device.
The Expansion output channels of the primary EXP device are sent to the AXI016 line outputs (see Connecting
a Primary Device to the EXP Input Port on the next page). The LED to the right of the EXP INPUT port blinks to
indicate a primary EXP device is connected.
NOTE: A primary EXP device is a device that has been set as a Primary Unit in DSP Configurator (see the
DMP 128 Plus User Guide for more information regarding primary and secondary EXP devices). DMP 128 Plus units are
set to primary by default.
DEXP Thru Port and LED — This RJ-45 EXP port connects the Expansion output channels of a secondary EXP
device to the AXI016. When a primary EXP device is connected to the EXP INPUT port, the Expansion output
channels of the secondary EXP device connected to the EXP THRU port are sent through the AXI016 to the Expansion
input channels of the primary device connected to the EXP INPUT port (see Connecting a Primary EXP Device and
Secondary EXP Device on page4). If no primary EXP device is connected to the EXP INPUT port, the Expansion
output channels of the secondary EXP device connected to the EXP THRU port are sent to the AXI016 line outputs
(see Connecting a Secondary EXP Device to the EXP Thru Port on page6). The LED to the right of the EXP
THRU port lights solid to indicate a secondary EXP device is connected.

AXI 016 • Setup Guide (Continued)
NOTE: A secondary EXP device is a device that has been set as a Secondary Unit in DSP Configurator (see the
DMP 128 Plus User Guide for more information regarding primary and secondary EXP devices). DTP CrossPoint units
are set to secondary by default.

COutput Signal and Clip LEDs — Sixteen pairs of stacked green and red LEDs light steadily when signal is present
and increase in intensity from -60 dBFS (lowest intensity, signal presence indication) to -3 dBFS (full brightness). The
red clip LEDs light solid to indicate clipping when a signal exceeds -3 dBFS. The red clip LEDs stay lit for one second
after clipping ceases.
Application and Signal Flow Diagrams
The following diagrams display the different signal ows when primary and secondary EXP-enabled devices are connected to the
AXI 016.
NOTE: Daisy-chaining two or more AXI 016 units together is not supported.
Connecting a Primary Device to the EXP Input Port
The diagram below displays the AXI 016 signal ow when only a primary EXP device, such as the DMP128Plus, is connected to
the EXP INPUT port of the AXI016.
• All 16 Expansion output channels of the primary device are routed to the line outputs of the AXI016 (see path A1 in figure 5).
• Expansion output channel 1 of the primary device is routed to the AXI 016 line output 1, and so on.

Connecting a Primary EXP Device and Secondary EXP Device
The diagram below displays the signal ow when a primary EXP-enabled device is connected to the EXP INPUT port and a
secondary EXP-enabled device is connected to the EXP THRU port.
• All 16 Expansion output channels of the secondary device are routed through the AXI 016 and into the primary EXP device
Expansion input channels (see path B in the figure below).
• All 16 Expansion output channels of the primary EXP device are routed to the 16 analog line outputs of the AXI 016 (see path
A1 in the figure below). Expansion output channel 1 of the primary EXP device is routed to the AXI 016 line output 1, and so
on.
• All 16 Expansion output channels of the primary EXP device are also routed to the Expansion input channels of the
secondary EXP device (see path A2 in the figure below). Expansion output channel 1 of the secondary EXP device is routed
to Expansion input channel 1 of the primary EXP device, and so on.

Connecting a Secondary EXP Device to the EXP Thru Port
The diagram below displays the signal ow when only a secondary EXP device such as the DTP CrossPoint 108 4K is connected
to the EXP THRU port.
• All 16 Expansion output channels of the secondary EXP device are routed to the 16 line outputs of the AXI 016. The
Expansion output channels of a secondary EXP device are only routed to the AXI 016 line outputs when no primary device
is connected to the EXP INPUT port (see Connecting a Primary EXP Device and Secondary EXP Device on the
previous page).
• Expansion output channel 1 of the secondary EXP device is routed to the AXI 016 line output 1, and so on.
