A:Answer With these systems you don't really need an AV Receiver at all. Bose designed them to work with your TV over an HDMI eARC connection. You can add a Soundbar, two Bass Modules, and the Surround cubes, then add them together through the Bose Music App.
If you truly want a Receiver to run the speakers through, you'll need to make sure that it has output to the eARC output for the Soundbar to detect it. But the Receiver is designed more for Passive systems, Bi-Amp systems, or speakers with the Positive and Negative terminals. Having this system myself, I don't need the receiver anymore, the system does fine on its own.
