Hi. I've just realised that my Rotel RB/RC 970bx's are producing mono sound but playing through both speakers. Or at least, I think they are. The power amp has a mono switch if bi-amping but it's definitely on stereo. The volume is full and the sound is fine, it's just that music is coming out of both speakers but it seems that it's the same channel coming out of each,. When I turn the balance either both speakers go off or both come on - rather than one or the other.... Any thoughts as to what the problem might be?
