Hello! Thanks for the answer! Can I try to clarify for myself? Isn’t Aux an input for external sources? This is what it says in the instructions and my little experience suggests this) Or can it be both an input and an output in Beo? Judging by the instructions, the device has only one Aux 8 pin socket, one Master Link, one digital (I don’t know which one), two pin 8 for speakers. In addition to the antenna inputs. I have one pair of RCAs sticking out of the wall, a second pair of RCAs (to the left and right of where the TV was), two 8PIN plugs a little to the side. Which one should I torture and plug into the receiver? Thanks in advance!
