Is there any difference in using a TS cable or a balanced TRS cable (pictured below) if you're carrying a mono signal (for example, an output from an audio card or an instrument)?
My understanding is that TS is for mono signals and TRS is for mono and stereo signals. But then I started reading about balanced VS unbalanced cables, and how the former is better at avoiding interference over long distances, as opposed to the latter.
So is the extra ring there to carry a stereo signal or to avoid interference or both?
Suppose you have a lot of money and a lot of distance to cover for a mono signal: do you buy a TS or a TRS cable?
I understand not all TRS cables are also balanced cables, so for the purpose of this question please assume we're exclusively talking about balanced TRS cables (VS unbalanced TS ones).
