I've just bought a quad artera play (not +) and have hooked it up to my pathos classic remix integrated amp using both XLRs and RCAs but I've had no joy getting any sound out of it. I've tried each of the two aux RCAs out of the Play into each of the 4 analogue inputs on the back of the Pathos but no joy. I just can't work out what I'm doing wrong. It should be a very simple set up. Before I return it as a non-working unit, if anyone owns an Artera Play and has any pointers, I'd be grateful. thanks.
