In order for sources to appear as Channel inputs on the Quasar Surface, they must first be created and a source type specified.
Using a PC connected to your studio network, enter the IP address of the Quasar Engine to display the web GUI.
Navigate to the Profiles menu, then to Sources.
Click Create New Source Profile.
Select the Source Type (A).
Enter the Source Name (B).
Click the Browse button to the right of the Primary Source field and select the desired source from the list.
Click "OK".
Repeat these steps for additional sources which will then appear in the Channel Input > Sources menu of your Quasar Surface.
For more detailed information on how to create and configure all of your network sources, please refer to the Quasar User Manual.
