Happens in speakers mainly.

The nice thing about the airmotiv speakers, is that each got its own volume, so issue fixed wink_face.gif...I know you love those babies, don't you?

Always feels better to have it 100% even, rather than going through tweaks. evil_smiley.gif

 

Makes life more simple.

 

Airmotiv's are the $h1F.

I listened to the Stealth, it's good, but.... too large..

Yes, it would be great if Asus could fix the sound imbalance issue through the speakers.  Maybe they can fix it through a firmware upgrade?

 

ASUSXONAR, could you bring that to the attention of your engineers?

Sound imbalance comes from volume pot and is dependable on it's setting. Mine is affected only at the very beginning of the scale, so at listening levels there is no problem.

As this is unrepeatable hardware problem, it could be adjusted using software (firmware) case by case - impossible mission.

The only solution is to use higher quality potentiometer.

Yes the Taiwanese Alpha potentiometer are the problem

Mine on rear output, pot is imbalanced all the way round to 5 o'clock. HP amp on the other hand was imbalanced and now it's not, however I no longer use it anymore. The pot is not of bad quality, it just doesn't gel with the units build

 

Maybe Japanese Alps potentiometer would of been a better choice

Processed By eBay with ImageMagick, R1.1.1.M2a

Just sayin...........

That picture of the japanese potentiometer doesn't have the two pins coming out the back unlike the stock taiwanese one.

If you can locate a japanese one with the same pins, i'll get two and try it out with my essence one.
It isn't really stock now anyway, might as well give it a try.

As of now, the imbalance is heard mainly from 7-12 o'clock.
From 12-5 o'clock i could hear that the left is 4-5% louder.
Didn't get this problem with the NuForce HDP nor DAC-100 that i have
The only way for me to get around this was by adjusting the L/R balances on Windows.

Well, maybe ASUS could offer us to upgrade the volume pot and fix the issue.

I'm using .22uf across pins 4&8, but .1uf works as well.

220nF film on the ad797 didn´t really do anything in my case. They remained unstable.

i got mine stable with two rocks and some jelly.

Hehe... I want to elect Tim for our own resident E1 Beta tester, for all the modding so far, and his willingness to go the extra mile gs1000.gif

 

Unfortunately I don't think its as easy as swapping the pot out, however I could be wrong. My point was if asus design the E1 with Japan Alps pot which has been proven to be robust in the DIY community, we more then likely would not have this problem.

 

Tim, if anyone can do it you can. I petition Tim aka cssarrow too Essence One mk2 team leader of project design ksc75smile.gif

"DIY Muses E1" 

 

Haha!

That's so cute! I love it. tongue.gif

 

It shouldn't be hard.

Just using a simple heat gun and heating up the bottomof the petentiometer until the solder melts.

Afterwards, use a long clamp to remove the old and pop in the new.

 

Might be difficult for those who doesn't have a heat-adjustable/digital heat-gun.

 

He said Essence One MK-2, hahah! classic.

That sounds pretty beast, not going to lie.

 

I'm looking online right now for some Japan Alps Pot with the same pins as the stock.

Help would be appreciated.

Does Asus use the same volume pot for the speakers and headphones?

 

If it is the same one, I wonder why the speaker side is a lot more noticeable?  It's actually quite bad and unacceptable.  If you're selling something for almost 1k, you have to get the basics right.

post #1964 of 3076
Yes, they're identical.
