I have a situation that has me completely befuddled. I made myself a set of XLR balanced lead, using neutrik connectors. They are 2m in length. Out of the set of 7 leads, two of them introduce noise into my system, the others are all fine. I have done a pin for pin check as well as ohming the connections. I have checked for continuity as well as checked for shorts and it all measures fine. This just totally blows my mind as i dont know what the problem is. Im starting to suspect the actual connector that it may not be making proper contact resulting in a floating connection. Any ideas would be appreciated as i have never seen anything like this . ??? ??? ???
