I have a problem.
I listen only balanced out.
The XLR have different voltages: 1.6 V and 1.5 V.
A speaker plays louder ...
How do I resolve?
Thanck you!

Double check all your jumpers and solder joints.

Thanks Russ. But I think I have experience in soldering :):) http://s775.beta.photobu...Buffalo22/library/?http%I have four Legato3 and all have difference in output XLR. 1.602V - 1.522 V 1,624 V - 1,528 V 1,618 V - 1,509 V 1,608 V - 1,514 V My speakers Coral 10 feel the difference.

I don't ever assume a person knows how to solder. :)
Have you measured the DAC output directly - with no legato.

It would have been helpful to know that you were running dual mono with B-II :)
One possibility is that the output of each of your AVCC modules is slightly different. Which revision of AVCC are you using?
Measure the output of each.

Excuse the delay in responding,the national day I was out in the mountains :)
Today I'll do measurements and return with a message!
Thanks.

Hi Russ,
We measured.
On the right AVCC (V-1.0) 3.28 V , and left AVCC(V-1.0) - 3,26V.

Hmm. That is pretty close.
You are using a single Legato and two DACs?

If you swap the addresses of the two DACs does the change follow the DAC?

I changed addresses in every way.
But I always to exit Legato3: left 1.6 V - Right 1.5 V :(

I see... Then we can rule out a difference in the DAC volume register.
How is the legato loaded? Are you measuring with no load?
It could be that the gain resistors are not well matched, but this seems a big difference for that.
What resistor values are you using and what tolerance?

Legato is connected via 10mkf BG-N with F5X balanced (EUVL amp)
Measurements - we made no connection to the amplifier.
Resistors are 1% tolerance, I checked again and it is.
I used R1-R4 180R / 1% R21-R24 10K / 1%
