I noticed that the front L speaker had 5 items while the right has 7. What's up with that? Does that mean that no adj was needed for those items?

This is really driving me crazy! Should I change the crossover and set the mains to small and leave the eq settings? Is so will that make things worse? Arhhhhhhhhhhhhhhhhhhhhhhhhh!!!!!

I have a rug that used to go under my coffee table that was about 10ft by 6ft. I had to remove it because my dogs dug a whole into it in one corner. I'm waiting to get it fixed. I wonder how much of a dff that would make? I would think it could only help.

So just to reinterate my last question.

If the YPAO set my mains to Large and the crossover at 160 and made frequency adj to my L,R and C channels, is it ok to change the crossover to 60 or 80 and my mains to small but leave the eq freq adj or is that not a good thing?

Hey Dan,
That receiver is an American version so I can't download the manual for some reason . I wouldn't use PEQ measurments established by YPAO @ 160. That why I recommended skip if viable with your receiver.

Hehe..before you make yourself nuts replace that rug/carpet before you proceed with any changes or updates to your system. Like was mentioned eariler your room is the issue because you've created big reflection point by removing the carpet.

BTW...You could try your hand at EQing yourself(ie: GEQ if applicable) but I quickly put that idea to rest after doing some tinkering... .

I looked at the eq but dismissed doing it manually. Way to difficult! I tried running the YPAO with the eq set to "Front". It set the crossover to 120 in this case.

In regards to the frequency corrections the YPAO is doing I'm wondering if the receiver applies the crossover first then makes the corrections to the channel frequencies or does it make the frequency corrections overall to the overall sound of the speakers then applies the crossover freq based on speaker size. If it's the latter, then changing the crossover freq afterwards wouldn't have an effect.

Looking over my manual(htr6190 aka: Rvx1800) it would appear to be the former. Only after the speakers are assigned will the processor start EQing your room. I'll likely defer to someone whom is more knowledgeable with auto set and room correction application.

Hey Billy, you are correct it's the former. I just read up on it on the avsforum for the Odessy. I'm assuming YPAO works the same.

For now I ran the YPAO using the "Flat" setting. It set a crossover at 120 which I lowered to 60. Since it set my mains to Large the frequency on those should be fine. I can live with how the center and rears are...for now!

Fwiw..I used flat and I have the Q4's as surrounds too...it just sounds better over the other 2 options(that being front or natural).

Dan, there doesn't appear to be any sensible way to reconcile the quoted language(actually p.30 rather than 29)about an appropriate crossover for each channel being set, with the display showing only the highest crossover frequency, which certainly isn't "appropriate" for the mains. You might try contacting Yamaha tech support and you might be lucky enough to find one who actually knows what's going on.

John, two things
1) my manual on page 29 and 30 doesn't say anything about the crossover just tells you what Auto PEQ does. Your manual is not the same as mine.
2) The manual I have indicates that the YPAO "adjusts the level of the specified frequency bands..of each speaker" It does not say that it adjusts the crossover for each channel. Also further in it when referencing the crossover it indicates "use this feature to select the crossover frequency of ALL the speakers set to SML.." It's a single setting.

I'll have to live with what I have or will have to get a new receiver.
