In Reply to: RE: About differences between cables - RCAs vs. XLRs. posted by beppe61 on April 16, 2015 at 01:20:28
IME, the XLR connector offers less RFI/EMI pick-up.
I like both the RCA and XLR cables, w/ the right synergy, one can use each connector in the same system.

Hi and thanks a lot for a very interesting information.
By the way i was thinking that the recorded sound comes into the world balanced as most microphones are indeed balanced, if i am not wrong.
So it makes sense to preserve the balanced operations throughout the audio recording and playback chain maybe ?
Speaking again of connectors i have a humble experience of replacing bad panel rcas on a unit with decent ones ... amazing. I was skeptical but maybe better contact changed the sound for the better.
So i have of course nothing against well executed RCAs.
Thanks again for the important advice about RFI/EMI.
Kind regards,

That's right!
"So it makes sense to preserve the balanced operations throughout the audio recording and playback chain maybe ?"
While the output of most all microphones are balanced and the input to the mic-pre is balanced, in almost all cases the mic-pre circuit is not.
I know of only one studio console that was balanced all the way through.
The Maytag project. This was years ago but I actually saw pieces of it.
I don't know of any professional tape machines that are balanced all the way through. I could be wrong.
In the tube era studio equipment used input and output transformers so they were balanced, in and out, but the circuits in between those transformers was single ended.

Hi and thanks a lot again for the extremely helpful advice.
I think i have got something very interesting, that is that most of the audio equipment circuits are actually unbalanced internally.
And indeed i have seen some schematics of amps and there is a little circuit at the input that takes the balanced signal and makes it unbalanced.
So maybe the balanced connections are implemented in order to provide a better transmission of the audio signal from one equipment to the equipment downstream ? well this is very interesting.
Thanks a lot again for the very valuable advice.
Kind regards.
Kind regards,
