Hi All, 
I did some searches but couldn't find the answer i am looking for, hopefully some of the pros here that use YPAO can help. 
I own a budget Yamaha receiver TSR7810, and i run 2 subwoofers. 
In the YPAO screen, after the auto calibration is done on multi points, there's a screen with speakers location show up. 
Usually i will go back in and do some manual adjustment such as speaker small xo 80hz, mess with speakers distances...so on....
When i come to subwoofer, the picture on the screen only show ONE subwoofer image instead of 2 that i am running. 
I watch youtube on people that's running on higher model do have 2 subs (1&2) show up for them to adjust individually..
But mine only show 1 sub, and i also have option to do manual adjustment on 1 subs universally.  
QUESTION : 
Is my AVR working fine even though it's only showing 1 sub on the picture? 
The subs do produce bass on both, but i am not sure if i am missing some adjustment on YPAO.
