I don’t see why that wouldn’t work.
I haven’t tried to do that, our setup is a little different, we are at full capacity with an AR2412, AB168, AR84 and of course the Dante card.
We went with the Dante card primarily for multi track recording and for an easy way to network audio for streaming or remote overflow etc.
I am looking forward to virtual sound check and training but I haven’t had the time to configure that yet. It’s not as easy as on the QU series mixers.
