OVERVIEW
The Glensound AoIP44 is an economical subrack designed to interface balanced analogue
audio circuits to and from a network audio system featuring Dante. It provides 4 audio inputs
to the network and also 4 audio outputs from the network on balanced 3 pin XLRs.
The AoIP44 can be used as a simple low cost audio I/O break out unit on a large Dante audio
network where it can be integrated extremely easily using the Dante Controller and is fully
compatible with any manufacturers Dante equipment.
The AoIP44 can also be used in very simple audio over IP scenarios where 4 bi-directional
audio circuits are needed to be distributed across a buildings network infrastructure, in which
case 2 x AoIP44 units can be used connected together across the network. The AoIP44 is
equally suited for high integrity broadcast purposes, intercom, just simple paging facilities or
simple distribution of audio.
Being part of our Signature Range, the AoIP44 comes as standard with removeable rack ears
(to allow front or rear mounting in 19" racks), mounting holes to allow under desk mounting
(the holes are equally suited for screwing the unit into odd places!) and an optional external
DC power supply for applications requiring redundant power supplies. It is housed in an all
anodised aluminium chassis.
As with Glensound’s other Dante products 0dB = -18dBFs.

P YSICAL INSTALLATION
The Glensound Signature Series have been designed to be highly versatile for installation and
can be installed in 19” racks with either their front or rear panels facing the front of the rack.
They can also be mounted underneath desks or work tops and can be either permananetly
mounted or stood (using the supplied feet) on top of desks or worktops.
INSTALLING SIGNATURE SERIES IN A 19” RACK
Firmly hold the signature subrack within the 19” rack and locate in 1RU of space. Use the
supplied 6mm rack screws to securly attach the unit to the rack.
INSTALLING AD ESIVE FEET FOR NON PERMANENT TABLE TOP MOUNTING
Remove the front rack ears (if they are not required), turn the unit upside down and attach
the supplied 4 adhesive feet as per the above drawing.

There are over 150 manufacturers that design Dante compatible equipment. In this example,
the broadcaster has an established Dante network. This is most likely to be an audio console,
or an intercom system.
The broadcaster needs to expand the network by adding an existing commentary booth /
voice over position. Using the AoIP44, the commentary position can be added to the existing
Dante network very cost effectively.
The AoIP44 is located in the commentary booth, and connected into the broadcast network
via a single CAT5/6 cable.
The Glensound GS-CU001B is the most widely used commentary unit by broadcasters. It
provides a programme mix output (direct outputs also available), and has 3 talkback outputs.
These connect to the inputs of the AoIP44 via XLR connections.
The AoIP44 outputs connect to the headphone monitoring inputs on the GS-CU001B via XLR.
This allows the commentators to hear 4 channels. These are typically the programme audio,
and talkback returns.
The audio routing can be configured via the Dante Controller software. Simply run Dante
Controller on any PC connected to the network. All available sources and destinations will be
shown on the AoIP44, and all other Dante compatible devices on the network. Click the
check boxes to route the audio in the desired directions, and the system is now ready to be
used.
Audio routing only needs to be configured by Dante Controller on the first time the AoIP44 is
connected to the network as all routes are stored locally on the device.

A small voice over studio is used is used for production of voice recording and by the
newsreaders. This is a separate studio to the main studios, and separate from the control
room.
As there are only a few channels to transmit between the locations the AoIP44 is a cost
effective option for connecting the bi-directional audio.
The mixer in the voice over studio only has 2 outputs the direct output of the microphone,
and a separate talkback channel. These connect to the local AoIP44 via XLR. There is a local
network switch in the voice over studio and this connects via a spare port to the AoIP44 via
CAT5/6, so that it is now recognised on the local network.
A second AoIP44 connects to the local network switch in the control room via a CAT5/6
connection. Two of the audio outputs from the AoIP44 are connected to the control room
mixer via XLR. We will configure this as the 2 channels of audio coming from the voice over
studio. The stereo programme output from the control room mixer is connected to two of
the AoIP44 inputs via XLR. All of the physical audio connections have now been made.
As both AoIP44s are connected on the network, the audio routing can be configured via the
Dante Controller software. Simply run Dante Controller on any PC connected to the network
and both AoIP44s will be displayed showing available sources and destinations. Click the
check boxes to route the audio in the desired directions, and the system is now ready to be
used.
Over shorter distances, network switches are not even required and 2 x AoIP44s can connect
directly. Audio routing still needs to be configured by Dante Controller on the units when
they are connected to a network, but this is only required once to set the required routing.

CONNECTING T E AoIP44 TO A DANTE NETWORK
The AoIP44 is a network audio device utilizing the reliable and versatile Dante audio over IP
protocol. Dante is a proprietary system (although very widely used) the originators of which
are Audinate.
The information below is only meant as a very basic guide. Full details of the power of Dante
network audio and instructions for using it can be found at www.audinate.com
Getting Dante Controller
If you are connecting the AoIP44 to a new Dante network the first thing you will need to do is
to get the free Dante controller software from Audinate.
This can be downloaded by visiting Audinate’s web site at www.audinate.com
Connecting AoIP44s To A Network
AoIPs can be connected to the network that you are going to use for your audio distribution
simply by plugging in the network connection on the rear. Once connected to the network it
will be possible to see the AoIP44 from within the Dante controller and route the audio
circuits.
Audio Over IP Network
We strongly recommend that you consider your network topology carefully and would not
recommend sharing broadcast audio and general data on the same network.
For more details of audio over IP network structure please visit www.audinate.com

Running Dante Controller
At the time of writing this manual, Dante Controller looks as per the screenshot below
The AoIP44 will have been named at the factory during test to allow them to be identified by
the Dante controller.
The format used for the factory name is
‘AOIP44-serial-XXXX-YYYYYY’. ‘XXXX’ will be the units 4 digit serial number, and ‘YYYYYY’ will
be the AoIP44’s MAC address.
Dante Controller TIP
If you have never run Dante controller before then make sure that on the bottom left of the
Dante controllers’ screen ‘P’ or ‘S’ is next to a green square as this indicates that it is
connected to a network. By clicking ‘P’ or ‘S’ a pop up box opens to allow you to set what
network interface the controller is using.

UPDATING THE ULTIMO CHIPSET
The Ultimo chipset is a device supplied y Audinate that does most of the processing for
the actual DanteTM network audio streams. There is one Ultimo chipset in each AoIP44. We
supply special code (a .dnt file) that sets up/ initiates the Ultimo chipset and makes it work
in particular way that is suita le for the AoIP44.
1. Finding Out What The Late t Available Ver ion I
Go the AoIP44’s’s we page at http://www.glensound.co.uk/product-details/aoip44/ and
open the ‘Firmware Latest Version’ Ta .
This will give oth the latest version num ers/ file names and also the location to download
the file from.
2. Updating the Ultimo Chip et
The firmware that runs on the Ultimo chipset is updated using Audinate’s Firmware
updating tool. The updating tool and a user guide can e downloaded from Audinate’s
we site:
https://www.audinate.com/products/firmware-update-manager
The actual firmware to install using the a ove tool can curently e downloaded from ( ut
check as per step 1 in case there is a more up to date version):
http://www.glensound.co.uk/Software/Dante/AOIP44_D=3.10_FW=1.0.0.dnt
When downloading the a ove file please make sure that you know where your computer
has saved it.
Please note we strongly advise that when you do the update that only your PC and the
Paradiso that you want to update are on the network to save accidently updating the wrong
Dante device.
