YPAO Subwoofer trim levels

[Jonathan Galea]

Here is some feedback perhaps I can help others too. Following your suggestions I had two options. Option 1 was to do a crawl test which I haven't done yet and option 2 was to re run ypao without running the Leo on the sub. I had some time and i did various ypao tests, all with front, center and 2 subs and just run basic ypao (just one measurement in the money seat).
EIxperiment 1: did a factory reset on both subs and made these settings on both of them prior to ypao as follows. Set the volume to 0 on the sub, phase to 0, LEO to off and eq to off. Then run ypao. The result was that on the trim level left sub was reading -5 while right -4 which was already an improvement. To get to 75 db on the Spl meter i had to bump up the trim levels on the avr to +5 left sub and +7 right sub.
Experiment 2 exactly as above but I bumped up the volume on the subs to +5 instead of 0. The results were -10 left sub and negative 9 right sub. I had to bump up the trim levels on the avr to +0.5 on both subs to get 75db.
I intend to do a full ypao of the whole system with the volume on the subs set to +7 and without Leo perhaps I will manage to get things right. I think the Leo on the sub and ypao on the avr are messing things up. I wish to get 75 db on the avr while on the negative..... Will let you know

You can raise the gain more on the subs to lower the output level on the avr as you can see. The big bump in trim post-YPAO to get to 75dB still seems too much....what does it sound like without bumping trim levels up in avr after YPAO alone?

As I stayed earlier if i left the trim levels untouched as applied by ypao the subs were punching really hard when I played music or movies but the spl meter was still indicating less than 70 db compared to the rest of the speakers that were all 75 db at the same given volume....

 

[ryanosaur]

When you are testing the Subs for output, are you testing them individually for 75dB or combined?

With Audyssey, for example, it is the combined output that you would test, not individual output. I would presume YPAO to work the same in that regard, though I could very well be wrong in that assumption.

Punching really hard doesn't mean much. You may simply be boosting too much, would be nice to see measurement for both YPAO alone and measurement after you tweak the trim levels.

I test one sub at a time can't do both together as far as I know....

 

[ryanosaur]

I have an idea... p!ssed I didn't think about him earlier.
@AcuDefTechGuy
Would you mind offering some advice to help our friend here get his Yammie and MA Gold Subs to play nicely, please?

Do you mean spl measurements since i already did that. Ypao only was under 70 db to get up to 75 I had to bump up the avr trim levels. If it is rew i still don't know how to use it!

No not spl measurements, rather in-room full frequency range measurements of subs alone (why can't you run simultaneously?) and with speakers....

How can i do this? I use pink noise from avr and do speaker by speaker including subs that are measured separately in my avr. I adjust the trim levels to get 75db on each speaker. Perhaps I am not understanding you.. Sorry for this

 

[ryanosaur]

I can only speak from my Audyssey/Marantz experience, but I can adjust each sub individually, as well as both as a pair.
This is why I summoned ADTG... he knows Yammies and hopefully MA (as he's a dealer. )

Trying to treat each Sub on its own, once the responses have been "corrected", is usually the wrong approach. You have to think of them now as a single unit.
And while I can adjust levels independently, as I said, I also have the combined response which I can adjust as well, without defeating my room correction (rather working within it's adjustment parameters).

Does that make sense?

You need a measurement mic and appropriate software. Popular is the miniDSP Umik-1 (and now 2) and RoomEQ Wizard software (usually just called REW). 75 on each sub would usually gain 2-4 dB together depending on placement/room, up to a max/ideal of 6dB. You may just like tons of bass, too.

I believe if his is like mine it depends on how he has them configured like left /right none or front to back or mono ! I run mine in stereo as i can independently control levels and peq for each independently need to know how he has these set .

You should be able to go into the configuration menu and choose how you want them setup .

After following Gene's advice on how to set up the yamaha 5100 video I set the subs to monoral x2. He said that it is the best option and specifically to avoid back and front setting.

I followed Gene's advice on a video he has on my specific processor and set them to no monoural.

I don’t use front to back either both mine are in the front next to my mains . With that being said on setup I run them as left and right to level match them then once there the same I can run them in mono or left and right it I run my crossovers high enough it depends on the desired effect I want every body does it a little different that’s the benefit of experimenting with different settings and setups .
Enjoy and best Regards !

I intend to invest in one and even a mini dsp 2x4 hd but I still have a long way to understand and learn what i should look for...

On the yamaha there are 3 options, left & right, front and back, and lastly monoural. I always used the latter. Perhaps I will try with the left & right and then will switch to monoural afterwards. I will give it a try and will let you know...

Plenty to absorb that's for sure on the subject. Also easier to share what you're doing with others to an extent as well with actual data rather than just descriptions and spl readings.....
