YPAO settings on Yamaha

[3db]

I ran that last night just to experimentand it got the distance to my front speakers correct but for the surrounds, it calculated the distance to be 11 ft where I have them set to 3 feet manually and measured. The surrounds are mounted on the wall close to the ceilings and angled down and slighlty towards the listenning position. If I were to draw a right angle triangle from the listening postion to one of the speakers, the hypotenuse is the distance from the speaker down to the listening position, with one side being the mounting height and the other side the distance from the wall the speaker is mounted on to the listening position.

The question; Is the distance claculated by YPAO the hypotenuse or is it the distance to the wall where teh speaker is mounted on relative to the listening position. Do rephrase this after alll of this, does mounting height of the surrounds factor into the YPAO distance calculation?

The other question I have is..when running YPAO, should I set some of the manual settings like speaker distance and size of speaker before or after YPAO?

I'm pretty sure it calculates the actual distance to the speaker, Not to the wall. I've never had YPAO be that far off on distance. Possibly a reflection?
I usually run the full YPAO once, mainly to check for out of phase, then adjust the distance and size manually, and run it again with phase, distance, and size turned off.

Question #1 - YPAO calculates the hypotenuse, so mounting height is factored in. FWIW I also have surrounds mounted ~6 ft up on a wall behind the listening position and YPAO on a RX-V659 correctly measured this distance. It even correctly accounted for the listening position not being exactly in the middle of the two speakers.

Question #2 - Set manual corrections after YPAO. FWIW, YPAO set my Sub's distance larger than actual, so I corrected it manually afterwards. I also changed the several speakers back to small and adjusted the crossover freq to 80 Hz (YPAO had set 100 Hz).

I thought about what you had posted. Wouldn't the EQ change if I set the speaker sizes first to small and then run YPAO as opposed to letting YPAO determine their size and then let it do the EQ? The whole EQ I would think is based on measured frequency response of the speakers so by setting them to small first, the bass response of the speakers wouldn't affect the measurements. Just a thought.

Kinda what I was getting at by running it a second time, after the manual changes.
I'm not sure if running twice is really necessary, but I think it's important to run it after any manual changes. Especially size. In the least, changing from large to small will change it's apparent loudness.

That makes more sense to me. Do you know if there is a nightime listening mode which limits the dynamic range a bit? Is it a menu option on the remote?

I can't recall the model you have.
There is a dicreet code for it on my 1800 that I get to thru my Harmony but I don't remember if there is a button on the remote or not. I'm at work.
