OVERVIEW

The Glensound DARK1616D is a digital to digital converter designed to connect
AES3 audio circuits to/ from 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 Dark1616D 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 Dark1616D 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 Dark1616D provides 8 balanced AES3 inputs and 8 balanced AES3 outputs to
the Dante network on rear panel D25 connectors wired to AES59 (also known as the
Tascam standard).

As per our other Dante equipment 0dBu = -18dBFs

CONNECTING THE DARK1616D TO A DANTE NETWORK

The Dark1616D 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 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 Dark1616Ds To The Network

Dark1616Ds 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 rear. Once connected to the network it will be possible to see the
Dark1616D 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 Dark1616D 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:

‘GLENSOUND-DARK1616D-SN-XXX’
Where ‘SN-XXX’ relates to the Dark1616D’s serial number which can be found

printed on its rear panel.

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 BROOKLYN MODULE

The Brooklyn module is a device supplied by Audinate that does most of the
processing for the actual Dante/ AES67 network audio streams. There is one
Brooklyn module in each Dark1616D. We supply special code (a .dnt file) that sets
up/ initiates the Brooklyn module and makes it work in particular way and we also
run extra code on its internal microprocessor to make it work correctly with the
Dark1616D.

1. Finding Out Current Installed Version

Open Dante Controller.
Open Device Info tab.

Double Click in the device that you are working with….a new window will open called

‘Device View (name of device’

Open the status tab.

The Firmware Version (of the Brooklyn module) will be found under the ‘Device

Information’ heading.

2. Finding Out What The Latest Available Version Is

Go the Dark1616D’s web page and open the ‘Firmware Latest Version’ Tab.
This will give both the latest version numbers/ file names and also the location to
download the file from.

3. Updating the Brooklyn Module

The firmware that runs on the Brooklyn module is updated using Audinate’s
Firmware updating tool. The updating tool and a user guide can be downloaded from
Audinate’s website:

https://www.audinate.com/products/firmware-update-manager

Please note we strongly advise that when you do the update that only your PC and
the Dark1616D that you want to update are on the network to save accidently
updating the wrong Dante device.

Page 21 of 25

AES67 MODE

The Dark1616D uses a module from Audinate called a Brooklyn Module for its
network audio interface. Audinate are the company behind Dante

module’s primary network audio protocol is Dante

®

, however Audinate have enabled
their module to comply with AES67 and therefore the Dark1616D can be set to
AES67 mode for interaction with other AES67 devices.

Please note however that Glensound are relying on Audinate’s AES67 interface and

are unfortunately not able to provide full AES67 support for the unit. AES67 support
should be sought directly from Audinate.

1. Turning On AES67 Mode

If you want to use your Dark1616D on an AES67 network and it has not been set to
AES67 mode then this can be set in Dante controller by double clicking the
Dark1616D to open the Device View window where you will find an AES67 tab to
enable AES67 support.

®

and as such the

Once the AES67 drop down box has been enabled you’ll have to reboot the
Daek1616D for the change to take effect. After the reboot go back to the AES67 tab
and set the multicast prefix address to one that is suitable for your newtork.

Page 22 of 25

2. Sending AES67 Audio

To transmit AES67 audio to the network a multicast flow must first be setup.
This is done by selecting the ‘Create New Multicast Flow’ Icon in the Device

View.

Tick the AES67 Flow check box, then select up to 8 channels to be included in the
flow then click ‘Create’

Once set the flows can be seen in the transmit tab of the device view.

Page 23 of 25

3. Receiving AES67 Audio

Once a compatible AES67 stream is detected on the network by Dante Controller the
AES67 flows will appear in the Dante Transmitters section in the Routing tab.

4. AES67 Restrictions

AES67 flows can only be generated with the following constraints:

 Multicast Only
 Non-redundant
 Destination address in range 239.nnn.0.0 to 239.nnn.255.255 (239.nnn/16),

port 5004

 48kHz sampling rate
