Introduction 1
1. AVN-Commentator Unit
Introduction
The AVN-CU2-DANTE and AVN-CU4-DANTE are portable commentator
units. Using Dante® AoIP together with 4 wire connections both the AVN-
CU2-DANTE and AVN-CU4-DANTE bridge the gap between old and new
technology, allowing the ease of connectivity & functionality of AoIP
together with the legacy connections needed to operate with existing
infrastructure in some stadia and sports grounds.
The units have an easy to use physical interface with metal shafted
encoders, illuminated buttons, status indicators, and a TFT display showing
useful information. An embedded web server is also implemented and is
used to access audio routing and more advanced options.
The unit supports up to 16 input and output AoIP channels and up to 16
simultaneous input and output AoIP streams. AoIP streams are setup via
Dante® Controller with more detailed configuration performed using the
built-in web GUI. Once Dante® flows have been made, the mix engine
allows inputs and outputs to be mixed freely to AoIP or physical inputs and
outputs, controlled using the programmable buttons and rotary encoders
on the unit.
The AVN-CU2-DANTE provides two locking mic/line inputs each with +48V
phantom power indication and a wide, adjustable gain range. It has two
stereo headphone outputs with locking 6.35 mm (¼ inch) jack sockets,
suitable for operation by two commentators. The AVN-CU4-DANTE
provides four commentator positions with four mic/line inputs and four
stereo headphone outputs.
The AVN-CU2-DANTE can be powered using Power over Ethernet (PoE), and
the AVN-CU4-DANTE using Power over Ethernet + (PoE+). Both units use
Neutrik EtherCON connectors, with primary and secondary ports for power
and data redundancy. There is an additional 4 pin XLR 12V DC input for use
when PoE is not available or extra power redundancy is required.
The AVN-CU4-DANTE also provides a fused AC mains electricity input on an
IEC inlet, with universal supply allowing for the varying voltage and
frequency requirements of different countries.
The AVN-CU2 provides 6 push-button rotary encoders and 12 key-cap
buttons, whilst the AVN-CU4 provides 12 push-button rotary encoders and
24 key-cap buttons. Push-button rotary encoders can be used to control,
input levels, output levels and panning of assigned audio sources whilst
key-cap buttons can be configured to perform various functions such as
taking commentators on-air and activating GPIO.
Each rotary encoder has a separate colour-coded meter section showing the
channel name, detailed level metering, left/right panning and a limiter
indication, the brightness of the display is adjustable allowing it to remain
readable in bright daylight. The colour of each encoder can be
programmed allowing a commentator to quickly identify source and
destination groups, and so perform adjustment to audio groups intuitively.
Metering is available on each input/output, with output metering
configurable as pre or post level adjustment. The top of the display shows
output metering, a limiter indication and the name of the output. A limiter
with a configurable threshold is also available on every output.
On the AVN-CU2, 2 four-wire RJ45 connections are available on the back
panel of the device. One is used as an input and the other is used as an
output, both connections can be individually configured as either digital
(AES3) or analogue. The input can be routed to the main (program) bus,
talkback buses, commentator headphones, the output four-wire
connection, and any AoIP outputs. The output can receive audio from the
main (program) bus, talkback buses, commentator microphones, the input
four-wire connection, and any AoIP inputs.
The AVN-CU4 provides further connectivity with four analogue line inputs
on XLR sockets with latching locks, six analogue line outputs on XLR plugs,
one RJ45 digital (AES3) stereo input and one RJ45 digital (AES3) stereo
output.
Each unit has dual redundant network ports on both RJ45s (PoE using 2
Neutrik EtherCON® connectors) and SFP cages.

1 Introduction

2 Getting Started
There are 10 configurable GPIO on a 15-way D-type connector with 1
switched changeover output.
All of the buttons have key-cap text and can be configured to allow for any
button function at any position. There are some standard operations
available:
• On-Air control for each commentator position, used to connect mic audio
to the main output, either over AoIP or via the physical audio
connections.
• A menu button can be used to access limited setup options on the TFT
display.
• Page buttons change the display and encoders to monitor an additional
set of sources, mix points or outputs. Up to 4 pages per display can be
pre-programmed. So, for the AVN-CU2 4 pages labelled 1-4 can be
configured on its display and for the AVN-CU4, 4 pages labelled 1-4 can
be configured on the left-hand display and another 4 pages labelled 1-4
can be configured on the right-hand display. For example; one page
might be used for commentator mics and headphones, one might be
used for talkback inputs, one might be used for physical, Dante, or tone
inputs, and another may be used for outputs such as the main output.
• User buttons can be programmed to perform various functions using the
web server, such as activating a physical GPO, a virtual GPO, a relay, or an
event.
• A cough control is available for each commentator position which
temporarily takes the commentator off-air while pressed.
• 4 T/B (talkback) controls are available for each commentator position,
which can be configured to initiate talkback over AoIP or the physical
audio connections using the 4 talkback buses. The talkback buttons can
be configured to operate with lazy-gang talkback. By default, activating a
talkback will also take the commentator off air until the talkback state is
cleared, it is also possible to configure talkback so that the commentator
remains on-air when talkback is invoked.
