I am very sorry for this obviously beginner query, but there is one thing about the cables I am using that is puzzling me a little (ok, a quite a lot).
I am using two pairs of powered studio monitors; klein&hummels (neumann), and adam. I am feeding the K&H's with a pair of old XLR -> TS cable (I suppose it must be TS as I am only seeing one ring on the 'jack' end of it). This is working fine.
I then have a set of XLR -> TRS cables (I suppose that's what they are as they have two rings on the 'jack' ends) to feed the Adams.
Now however, when I tried to plug the XLR -> TRS cable into the K&H's, all I heard was HF, as if it was only the tweeter playing (or indeed, as if some signal was getting (phase?-)cancelled. I don't understand why this would be the case, and why would a technically 'better' cable (the TRS) perform incorrectly, while the TS cable is working fine.
BTW the Adams work fine with either set of cables.
Could anyone help me out as to what may be happening, and what I am doing wrong?
Thank you very much.
