Pretty much done for tonight. Went to work at 1:00 AM.
My wife, mil, and daughter are going shopping tomorrow. I will run YPAO then.
There is a difference in the LFE output settings with this unit compared to my 1400.
The 1400 had LFE settings of FRNT, SWFR, or BOTH. I used SWFR, set all speakers to SMALL, and set x-over to 60Hz. A non LFE source would send LFE to sub. FRNT would send LFE to the mains. BOTH would send LFE to sub and mains, and not allow you to set the mains to SMALL.
The Z7 has LFE settings of Front + SWFR, SWFR, and Front. Front + SWFR sends LFE to the sub during non LFE playback with all speakers set to SMALL. SWFR only sends LFE to sub if there is a LFE track. A Front option will not allow you to select the SMALL size in the GUI for the mains, and no LFE will be sent to the sub.
It's different, and better thought-out. I see why there has been so much confusion with this in the past.
