Connection options from Node to Denafrips Iris to Pontus

I have the Node 2, and the manual states about the USB port that “This is not for consumer use. Only Authorized Bluesound Service personnel can access this USB port and  SERVICE control button.” Of course it’s possible your version has the USB output too.

I just looked at the current version’s specs, it’s quite different than mine, and the USB output is listed.
