Will my AX5i play true 6.1 or 7.1? If so does it play 6.1 on THX,Pro Logic11? The only 6.1 I see is NEO:6 Cinema is that what Im ment to use and is it something that is decoded true? I dont think this amp is right for true 7.1 am I correct? If you have aset up for 7.1 with 2 rear speakers do they both play in mon o if its a 6.1 film?
