I'm trying to put together a system for a friend that wants multi zone, multi source. I know the 601 does it but on the Onkyo USA site it says the zone two line out is multisource but does not specify that the powered zone 2 is multisource. Crutchfield also specifies you need an external amp to use zone two on a seperate source? However Crutchfield has been known to get things wrong every now and again. Can anyone with this unit confirm if it does powered zone 2 with a separate source? I don't want to have to tell them they need another receiver or amp to power the 2nd zone. Thanks in Advance!
