xlr shielding?

[mino]

Any one know about this. I overheard a conversation today that led me to believe that XLR cable is shielded because it reverses the phase from input to output therefor loosing any rf interference. I didn't have time to get involved with the conversation and now feel like I may have misconstrued the whole thing. Anyone?

yes if you dont wire it correct and no if you wier it correct

So Oleg, are you saying that you have to physicaly change the properties of the cable to make what I overheard true?

I just re-read you response, of course that's what your saying. Thanks for comment.

the xlr is -connector , the cable is cable and if we are talking balance link that connect one point to another the there is a phasereverse betwin the signals which runing on each lead , so everu ham that comming from other sorses is rejected sines it had been inversed by fase the real signal is a-(-a) =2a , the ham is b-b=0 , that why it good to run balancing lines for long distances , for short the unbalance is good enouth ( short -is very short , 2 mitters maximum)
