Hi,
i have found this adapter in the Neutrik web pages
If i understand correctly there is a XLR in and a RCA out and ground isolation is provided
I wonder if this could be beneficial for good sound in a normal and crowded home environment with dirty mains.
I have both a dac and a preamp with balanced outs, while i have an amp i like unbalanced.
Where it would be better to put this isolator ? after the dac of after the preamp ?
I think that ground isolation could be nice
Thanks a lot for any suggestion.
Kind regards,

The Neutrik web site threw a "404" error from your link. It looks like the product nomenclature might have changed.
Neutrik has lines of converters to convert balanced to unbalanced analog signals and to convert balanced to unbalanced digital signals. From looking at the web site, it looks like the product you had in mind is an analog converter, but this would be just a guess.

Hi and thanks and sorry for the belated reply
Actually my main goal is to separate source ground from the rest of the chain
For instance i could do this with an optical digital cable instead of signal transformers (a much cheaper solution)
But someone advised me not to do this because jitter could increase
I have a very crowded system and ground loops are always an issue.
But good signal transformers are very expensive.
I will have to think about a little more.
Thanks again.

Hi i have changed strategy
I have decided to put a toslink in the middle of my chain
i listen only to digital these days and everything pass through the pc
An optical cable is the easiest way to get complte galvanic isolation
Thanks again

Why, IME every additional connection degrades the sound somewhat. I would think that minimizing the number on connections is the way to go.
By denying scientific principles, one may maintain any paradox.

a 75 Ohm to 110 Ohm converter using a small toroid transformer. Sounds OK
Hi and thanks for the valuable reply
My main concern is to ruin to source
From the schematic i see that pin 1 of the XLR is grounded and 2 and 2 connected to the primary of the transformer
Does this ruin the source ?
And where to put it .. after the dac or after the preamp ?
But above all i would not ruin the equipment with something like a short circuit between phase + and pahse -
But i like the ground isolation provided very very much.
I have ground problems ... i am sure of this
Because if i short the preamp inputs there is no noise to speak of.
If i connect the source ... tac ! i have noise ... very disturbing
Thanks again.

Unless I am mistaken on your unit, this is for converting 75R 0.5V digital
to AES/EBU 110R voltage level for use as input to a dac. It is not meant to be usede after a preamp or in the analog line.
Hi and thanks again
Now i understand it is not for me. I would like to separate source and preamp grounds, like for instance a coupling transformer does.
Unfortunately i have not a scope to see the quality of noise coming from the source but i think it is ground related.
But i have decided to do differently
I will get galvanic separation by means of an optical cable between the source and the dac.
I want to get rid of noise ... perfect silent and the music above.
Thanks again.

Do not ground source and use one point grounding at the last destination
Hi and thanks again for the very kind and valuable advice.
It has helped me to understand that i should not go this way.
I will use a toslink connection to achieve galvanic separation of the source. I will loose maybe somtething with an optical cable, but i need to isolate.
Thanks again.
Kind regards,
