YPAO: How it went for me
I just finished various music and blu ray testing following my first single position YPAO test and settings. YPAO improved levels and tone output significantly. I don't hear any distortion and like the setup a whole lot better now.Specifics:Setup:
I silenced everything in the house including the fridge, fans, swamp cooler, clocks, etc. I decided I wanted my recliner in position since it appears to be a BIG acoustical absorber, so I reclined it halfway, stacked some pillows and acoustical foam and placed the mic where my ears will be. I left the room during the countdown to the test. Those are some pretty peculiar tones! I was pleasantly surprised that with the system set up for 7.1 + 2 speaker arrangement, YPAO tested all the speakers.No errors:
No wiring errors or other problems reported by the system.Measuring position:
Single and located where my ears will be on average when in the recliner. Recliners of course make this a moving target. I stayed with single measurement because I'd read of too much fuss with multi position measurements. I may try multi position later with 3 different reclined positions. I'm a widower and live alone, so there was little need to try to measure for other seating positions. During parties and such, the AVR will be in "party mode" anyway.Speakers:
With the exception of 2 Klipsch RB-41 II surrounds and 2 Yami powered subs, all speakers are Fluance XL series. Their tone balance was much better than the JBL towers and other speakers they replaced. However, the YPAO definitely improved the tones even more.
One striking difference: In the grumbling monologue at the beginning of Avatar where the movie maker wanted the baritone actor to sound like he was in a box (statis chamber), his voice was previously very annoying and difficult to listen to. It is now much clearer even though the source audio recorded in that particular scene wasn't very good, IMHO.Distances:
Distances recorded appear very accurate with the exception of the subs. Maybe because there are 2 about a half wavelength apart, it thinks the sub is at 11.4 feet whereas one is about 6 feet towards right front of measuring position, the other maybe 2 feet behind. Total distance between the subs is probably 10 feet. I have them sitting at non-canceling angles 'cause that worked best during "the sub crawl".
I'm not hearing any bad manners from the subs so I'm going to leave them alone for now.Levels:
I'd seen that the one half setting was usually too much for one sub, so since I'm using 2, I turned them both down to 4 of 10 volume on the sub boxes before testing. Pass switch on both boxes set to "high". YPAO added 1.5db. Close enough for government work.
All the speakers in decent locations had small sound level adjustments ranging from -1.5db to +1.5 just as I expected.
Exceptions: The speakers in poor locations required sometimes significant adjustments - also as expected. The RF main speaker has a +2.5db adjustment and that makes sense due to some unsolvable room locations problems.
Big adjustments: The front presence
speakers were adjusted by YPAO +8.0db on RF and +9.0db on LF. Because of the room design, this is somewhat expected since some of the sound from those speakers is reflected off the back of my 65" panel TV into a wall treatment that damps any echo from this out. It was about the only place to put those speakers and I need them for the dialogue lift. I'm a little iffy about that much adjustment, but it sounds great so I'll try it for awhile.Size:
YPAO set all the speakers to large. I manually set them back to small. Is that correct or should the fronts maybe be on large due to 8" downfiring woofers? Or would doing that stop signal from going to the subs?
I had read extensively in AVSForum about YPAO and was really concerned that I was going to run into errors or distortion or poor sound. None of that happened.
The system went from pretty darned good before YPAO to clearly the best sound system I've ever owned.
I like the system best using YPAO Flat. I'm teetering on whether I like "Enhancer" on or not. I'm thinking not.
I'm acutely aware of some serious hearing loss I have in certain frequencies and tinnitus in high frequencies. So I'm surprised that I would or even could notice this much improvement with YPAO being that I have damaged ears and all. OTOH, before hearing damage, my ears measured well above average. So I suppose I'm hearing the improvements in frequencies where I still hear very well. Who knows.
Anyhow, I'm a happy camper.Edited by MountainMichael - 6/11/13 at 12:27pm
