I’ve connected S10 preamp with aux in onto dedicated network to A30 amp which is connected by powerline AV1000 network extenders. I receive music by the A30 but cannot adjust the volume on the A30 with remote when on ethernet. When in range of WIFI and come off ethernet I can adjust volume with remote. Anyway to remedy this? I was wanting to place amps on powerlines or wifi (if in range) in multiple rooms. If I can’t adjust amps with remote when hardwired I’ll have to add preamps, since phone with app can’t reach input S10. Help!!
