After rereading the M22, M60, M80 thread from link above, I'm ready to buy a set of M60's to go along with my M22's. LOL. Concerning the A/B switching on the receiver, am I understanding this correctly? That the B is for Zone 2, so the M60's are hooked up to A (Zone 1) and the M22's are hooked up to B (Zone 2)?
