XLR, Balanced, same thing???



I know that XLR is a type of connector, but what is balanced? I mean I know that there are balanced inputs on amplifiers that aren�t truly balanced at all. Does this also apply to cables as well? I guess my question is, just because a cable has the XLR type of connector, does it mean that it is balanced ? I would also like to know if all cable companies follow some sort of standard when it comes down to the pins on the cables, i.e. is pin number 1 always ground no matter what cable you use? What about the components used, do the manufacturers follow the same rule of thumb?

Thanks

Having XLR connectors on a cable does not necessarily mean that they are balanced. If you have need of a truly balanced cable I would pay special attention to the issue to make sure you are getting what you need. There seem to be multiple standards regarding the pin assignments that would affect the phase relationship of the cable. Marantz refers to European and US standards that are of opposite phase. I am not sure about the ground pin issue, but I would be sure to specify exactly what you are expecting prior to purchase or commission.
Since I do not have adequate knowledge to answer your question I have provided the link below for a short explanation.
