Using AES67 with Symetrix Dante-enabled DSPs

The purpose of this Tech Tip is to provide information and instruction on using
AES67 with Symetrix Dante-enabled DSPs.

The AES67 standard provides interoperability between different forms of AoIP
(Audio over IP). AES67 is not a networking solution in and of itself, but rather a
group of interoperability specifications for connecting media streams.

AES67 is supported by various IP-based audio networking systems such as Dante,Ravenna, Livewire and Q-LAN.

Because Dante supports AES67, this allows Symetrix Dante-enabled DSPs to
receive and transmit audio with other IP-based audio networking systems, Q-LAN
as an example.

When using Symetrix Dante-enabled DSPs with AES67, there a few key points to

keep in mind:

  • Symetrix Dante-enabled DSPs are compatible with AES67, but are not AES67 specific hardware.

                  AES67 stream assignments are handled by the receiving device:

                  AES67 streams will only appear as a transmitter in Dante Controller.

                  AES67 transmit streams from a Symetrix Dante-enabled DSP will NOT be                             assignable in Dante controller.

  • Here is a link to set up AES67 receive flows with Q-SYS:


  • AES67 is capable of unicast and multicast communication, however Dante’s

implementation of AES67 currently only supports multicast.

  • When two Dante-enabled devices are passing audio between each other

they will always use Dante for the communication, regardless of AES67


  • Audinate’s Ultimo chipset does not currently support AES67
  • Here is a link to the AES67 standard:


AES67 Receive Stream 

Here are the instructions for creating AES67 receive buses, using the generic
Network Receive Modules:

(This example uses a Radius AEC and QSC Q-SYS Core 250i)

1. From the Toolkit, add a Radius AEC to the Site View page.

2. Open the Design View page by double-clicking the Radius AEC.

3. From the Toolkit, expand Network I/O Modules, then expand Receive

4. Double-click or drag in a New Network Receive Module.

5. The Network Receive Module Properties window will open automatically. Click the button to “Add New Bus”.

6. The Network Receive Module Properties window will open automatically. Click the button to “Add New Bus”.

7. Change the type to AES67.

8. Click the “Browse AES67” button.

9. Select the desired AES67 multicast stream from the list.

10. Click the “Select AES67 Stream” button.

11. The New Bus window is now updated with the AES67 stream information (device network name and channel names).

12. The new AES67 receive bus is available in the Network Receive module Properties window.

13. Click Ok. The new receive bus has now been created.

14. Push the site file and Composer will make the AES67 to Dante subscriptions.

AES67 Transmit Stream
Here are the steps to create AES67 transmit streams:
1. Open the site file to the Design View page.
2. From the Toolkit, expand Network I/O Modules, then expand Transmit Modules.

3. Add a New Network Transmit Module. The Network Transmit Module Properties window will open.

4. Edit the name of the transmit bus.
Note: Naming of transmit buses is very important for organization.

5. Select the number of channels in the transmit stream.

6. Select the transmit bus type.

7. Name the individual transmit channels.

8. Click OK and the transmit bus will be added to the site file.
