I have a relatively new Samsung 4K UHD TV (UN50JU6500FXZA). I also have an older Sony Receiver (STR-DE185) that is connected to 4 speakers. The two devices are approximately 18 feet apart. My question is can the receiver be connected to the TV in some way? I know the TV accepts HDMI connections. I don't know what the receiver accepts. RCA connnections? (It's in a cabinet now and I have physical limitations preventing me from getting to it.) I was considering purchasing a soundbar but thought if I can save money, why not?
