OVERVIEW
The Glensound DARK16AO is a digital to analogue converter designed to connect
outputs from a DANTE®/ AES67 audio network to line level analogue audio inputs
on 3rd party equipment.
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 DARK16AO DANTE® audio interface is compatible with all
DANTE® audio interfaces across all manufacturers. Further details of DANTE®
network audio can be found at www.audinate.com
Intended for live on-air broadcast applications, the DARK16AO 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 DARK16AO provides 16 analogue line level (0dB) outputs from the DANTE®
network. These outputs are provided on rear panel electronically balanced XLRs.
Internally the DARK16AO features a Brooklyn module from Audinate (the company
behind Dante®). This module can be set such that it is AES67 compliant, and as
therefore it can be integrated in an AES67 AoIP network instead of a DANTE® one if
required.

DARK16AO 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 DARK16AO 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 DARK16AO to be
updated. To prepare the DARK16AO 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.

6. Analogue outputs 1 –16
Each XLR provides one line level balanced audio channel output from the
DANTE® network.
7. 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 DARK16AO is designed to operate with either primary or secondary
mains sources or both for power redundancy.
8. 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 DARK16AO is designed to operate with either primary or secondary
mains sources or both for power redundancy.

CONNECTING THE DARK16AO TO A DANTE® NETWORK
The DARK16AO is a network audio device utilizing the reliable and versatile
DANTE® audio over IP protocol. DANTE® is a widely used proprietary system made
by Audinate.
For full details of the power of DANTE® network audio and instructions for using it,
visit www.audinate.com
Getting Dante® Controller
If you are connecting the DARK16AO 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 DARK16AO To the Network
The DARK16AO 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 panel. Once connected to the network it will be possible to
see the DARK16AO 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:
The DARK16AO 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:
‘DARK16AO-sn-396’
Where ‘sn-396’refers to the its serial number of the unit.

Page 15 of 24
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 FIRMWARE
The DARK16AO is a complex digital audio system comprising of a DSP and several
Micro Controllers. All these items run software and may need to be occasionally
updated.
Equipment needed
A windows based PC
USB Type A to Mini B cable
A copy of ‘DfuSe Demo’ software
The latest firmware from Glensound
A DARK16AO and mains power
Instructions
1. Download and install DfuSE Demo
‘DfuSE Demo’ is a firmware updating tool that is required for loading new
firmware on to the DARK16AO.
It can be downloaded from the STMicroelectronics website found here:
https://goo.gl/AbzhsA. It is the file named “STSW-STM32080”.
Once you have downloaded this file you will need to extract the .exe
“DfuSe_Demo_V3.0.5_Setup.exe”, then run and install it.
2. Download firmware
The latest firmware for the DARK16AO can be found on the Glensound
website, under the product page for DARK16AO. Once you have downloaded
the file, place it in a folder or location of your choice.
3. Connect To A PC
Connect the DARK16AO to the PC via the USB cable. The Mini USB
connector is located on the front panel of the DARK16AO.

4. Firmware update preperation
To prepare the DARK16AO for a firmware update;
1. Power on the unit
2. Press and hold down the reset button
3. Press and hold down the identify button
4. Release the reset button and then release the identify button a second
after
Your PC should make an audible sound when this process is successful as
windows is detecting a new USB device.
5. Loading the firmware
Now open DfuSe Demo.
If the DARK16AO successfully entered DFU mode then it will appear as ‘STM
Device in DFU Mode’ under the ‘Available DFU Devices tab’.

Now the .dfu file needs to be selected so that DfuSe Demo knows the correct
firmware to put on to the DARK16AO.
Click choose and then select the .dfu file that you downloaded from the
Glensound website. This will be located in your downloads folder by default.
If the file loads successfully then it will read along the bottom ‘File correctly
loaded’.
