Hi Leemix,
I did read the manual and checked several YouTube videos and to my understanding this receiver has a “powered zone 2” option which would allow for simply placing speaker wires into the zone 2 speaker connection without the need for using the line out for zone 2 (which is what I did). I did find Z2 on the receiver, however on Z2 it does not play the outdoor speakers (whose speaker wires are in zone 2), but it plays the indoor speakers distorted. Thanks for the quick response.
