Quantum: Route Mac System Audio to Different Outputs

Published November 4, 2021


It is possible to route system audio (browser, music applications) to different outputs on your Quantum Thunderbolt interface by creating an aggregate device in Audio Midi Setup.



PLEASE NOTE: You must have the Universal Control application closed before opening Audio MIDI Setup as Universal Control can conflict with Audio MIDI Setup.


1. First open Audio Midi Setup by navigating to Applications > Utilities > Audio MIDI Setup





2. Click on Create Aggregate Device on the bottom left-hand corner of the Audio Midi Setup window.




3. An Aggregate Device tab will now populate on the left-hand pane. Select this tab and it will highlight blue. While on the Aggregate Device select the Use checkbox next to the Quantum interface.




4. Then click Configure Speakers at the bottom right-hand corner of the Aggregate Device window.




5. With the Configure Speakers menu open you can select your desired speaker configuration. Apple offers Stereo, 2.0 surround, 5.1, 6.1, 7.1, 7.1 rear surround configurations. The image below has the stereo option selected. You can select what outputs you want to send your system audio through by selecting the different channel drop-down menus. These are highlighted in red on the image below.
