I'm trying to connect the Denon AVR S540BT to my Sonance amplifier 12-50 using the preout via Y spliter RCA cable, but I can't get any sound to all the speakers connected to the Sonance. Anyone have any suggestions of troubleshooting this? Or how I can connect the 2 to get sound?
I've tested the Sonance amplifier is connected to 5 different speakers around the house. There is sound when I connect my phone via y spliter 3.5mm to RCA. I've also tested the cable and they all work. Not sure where to go from here. I've also called Denon for support but they have not called back.
