OVERVIEW
The Glensound DARK8ADI is an analogue to digital converter designed to connect
AES3 and line level analogue audio circuits to a DANTE® / AES67 audio network.
DANTE® network audio is a common protocol for distributing high quality linear
audio over standard IP networks and it is widely used by many audio equipment
manufacturers. The Glensound DARK8ADI DANTE® audio interface will be
compatible with any other manufacturers DANTE® audio interface. Further details of
DANTE® network audio can be found at www.audinate.com
Being designed for live on-air broadcast applications the Glensound DARK8ADI has
been designed with multiple redundancy capabilities. It has 2 mains power sources
and it also has fully redundant network connections for both Copper & Fibre circuits.
The DARK8ADI has 4 balanced AES3 inputs and 8 balanced analogue inputs on
rear panel XLR connectors. In total 16 audio circuits are sent to the Dante® network
from the device. 8 of these audio circuits are derived from both the AES3 and
Analogue inputs with the AES3 input being sent to the output when a valid AES3
siganl is detected, if no valid AES3 signal is present then the analogue audio input
wil be sent to the Dante® network in its place. The other 8 channels being sent to the
nmewtork are always derived from the 4 x AES3 inputs.
The Glensound Dark8ADI utilises Audinate’s Brooklyn module for its aoip network
interface, therefore it is also AES67 compliant.

DARK8ADI FRONT PANEL LAYOUT
1. PSU and Link status
There are 4 red LEDs and 4 green LEDs that illuminate depending on the
status of the link. Red indicates no connection, green indicates a successful
connection.
For example, if you have connected the DARK8ADI to two separate PSUs,
only one of which works then you will have a red ‘Fault’ LED illuminate to
warn you that there is no power detected on the connection that is not
receiving mains power.
2. Alarm status connection
This 8-way female D-type connector will report the failure of a link status if
one is detected whilst in operation.
3. USB connector and update buttons
The MINI USB connection allows the firmware of the DARK1616S to be
updated. To prepare the DARK1616S for a firmware update; power on the
unit, press and hold down the reset button, press and hold down the identify
button, release the reset button and then release the identify button a second
after.

4. Network SFP Connections
There are 2 standard network data SFP sockets provided to allow redundant
network connectivity if using DANTE® network audio protocol. They are both
gigabit network connections. They accept standard SFP modules. The status
LEDs flash to show when data is being correctly communicated with the
attached switch.
If you require SFP modules then please email [email protected] for a
quotation.
Network Note
Factory default is to have the SFP & RJ45 sockets set to work in redundant
mode.
It is possible using DANTE® controller to set these network interfaces to work
as a network switch instead of the redundant mode, meaning other network
equipment can be connected to them.
5. Network RJ45 connections
There are 2 standard network data RJ45 sockets provided to allow redundant
network connectivity if using DANTE® network audio protocol. They are both
gigabit network connections. The status LEDs flash to show when data is
being correctly communicated with the attached switch.

1. Analogue inputs 1 –8
These 8 analogue audio inputs are electronically balanced and accept line
level (0dB) signals.
These analogue inputs will be routed into the AoIP network if no valid AES3
input is detected on the equivalent AES3 channel. One AES3 channel carries
2 audio channels therefore:
AES3 I/P 1 = Analogue Inputs 1 & 2
AES3 I/P 2 = Analogue Inputs 3 & 4
AES3 I/P 3 = Analogue Inputs 5 & 6
AES3 I/P 4 = Analogue Inputs 7 & 8
The signals can then be routed via DANTE® to anywhere on a network.
2. AES3 inputs/outputs 1 - 4
The 4 balanced AES3 inputs can accept AES signals up to 192kHz.
These AES3 digital input signals always take priority over analogue inputs to
the 8 switched AoIP outputs.
Therefore, sending an input to channel 1 in both digital and analogue domains
will result in the digital signal being accepted and the analogue signal being
disregarded.
4. Analogue inputs 1 - 8
3. AES3 inputs 1 - 4
2. Primary Mains Input
1. Secondary Mains Input

Page 12 of 26
3. Secondary IEC Mains
The standard IEC mains plug accepts external AC voltages of 100 - 240 VAC
+/- 10%. There is a non-accessable internal fuse for this input.
The DARK8ADI is designed to operate with either primary or secondary mains
sources or both for power redundancy.
4. Primary IEC Mains
The standard IEC mains plug accepts external AC voltages of 100 - 240 VAC
+/- 10%. There is a non-accessable internal fuse for this input.
The DARK18ADI is designed to operate with either primary or secondary
mains sources or both for power redundancy.

CONNECTING THE DARK8ADI TO A DANTE® NETWORK
The DARK8ADI is a network audio device utilising 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 inferno 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 DARK8ADIs To The Network
DARK8ADIs can be connected to the network that you are going to use for your
audio distribution simply by plugging in either, and, or any of the network
connections on the front. Once connected to the network it will be possible to see the
DARK8ADI from within the DANTE® controller and route its’ 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 the DANTE® Controller looks as per the
screenshot below:
NOTE: The Dark8ADI only transmits into the Dante® network and therefore only
appears on the transmitters section of Dante® controller.
The DARK8ADI 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:
‘DARK8ADI-sn-XXX
Where ‘DARK8ADI-no-XXX’ refers to the Glensound product i.e. DARK8ADI and its
serial no.
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.
