Summary: I have had this receiver for 2 year now. I've been using it everyday as my entertainment hub. I have My PS3, and DirecTV receiver hooked up to it, and all audio and video runs through it at all times. My TV speakers are awe full so I always listen through the receiver and home theatre speakers. The monitor out is hooked up to the TV (obviously).
Summary: I have been installing my new home theatre (5.1 plus an outside pair and a line out to another amp) for two weeks since receiving this Onkyo RC-180 receiver so now I can speak to the limitations of this unit. Most importantly, zone 2 and 3 are only available for analog input sources (even the tuner is not available for output to those speakers.
Zones 2 and 3 do not work like I thought they would. EDITED: BROKEN

Summary: I reviewed the instruction manual before purchasing this because zone 2 and 3 audio are important features for me. I read the manual to say that you can have 7.1 in the main room. But if you activate zone 2, then the main room will drop down to 5.1. That makes sense because you're now powering two speakers in a separate room so you drop two speakers in the main room (7 to 5). If you activate zones 2 and 3, then the main room drops from 5.1 to 3.1.
