For this operation, the amplifier must first be configured in Dante Controller so that AES67 streaming is enabled. This is done by following the steps described in the section ‘Enabling AES67 and Receiving Flows’ of this document.
To set up a Q-SYS AES67 transmitter:
Open Q-SYS Designer.
In the Inventory pane, click the ‘+’ symbol to add a device.
Select the option Streaming I/O and then AES67 Transmitter (Figure 4).
Figure 4 – List of streaming devices available in Q-SYS Designer.
An AES67 Transmitter device will be added to the Inventory list. Click, drag and drop this device as a component onto the design schematic window (Figure 5).
Figure 5 – AES67 Transmitter device in Q-SYS Designer.
Click on the AES67 Transmitter component to view its properties under the Properties Pane. Set ‘Connection Mode’ to ‘Auto’ and edit the ‘Channel Count’ to the number of channels to be transmitted from Q-SYS to the amplifier in the AES67 flow (Figure 6). It is important to note that it has been verified that changing the ‘Channel Count’, without deleting/redoing the patching in Dante Controller, creates audible HF distortion in the audio signal.

Save the design to the Q-SYS Core by pressing F5 or selecting File > Save to Core & Run.
Double-click the AES67 Transmitter component to open the Connection pane (Figure 7).

Note that the AES67 Transmitter automatically assigns a name to the ‘Stream Name’. The AES Transmitter device is now available for connection with other AES67 devices and can be seen in the list of Dante Transmitters in Dante Controller (Figure 8).

Note from ‘Figure 7’ that Q-SYS has automatically assigned an IP address to the AES67 Transmitter flow (239.69.xxx.xxx). This default configuration is appropriate when only one AES67 Transmitter component is used in the Q-SYS design schematic. However, when several transmitter components are added to the design, Q-SYS will incorrectly assign the same IP address to all AES67 flows. In such instances, it is recommended to manually configure the IP of the ‘Multicast Address’ in each transmitter component independently (Figure 9).
Figure 9 – Manual configuration of the ‘Multicast Address’ for an AES67 Transmitter.
For best practice, it is recommended that static multicast IP addresses are always used for Q-SYS AES67 Transmitter flows, as it will make the network routing more reliable. This is specially the case when devices are restarted and/or put in a different network, causing the IP addresses to change and the routing to be lost.
