It's not a=20 snake in the common sense of the word; there is dedicated wiring inside=20 the building. The inputs appear at stage boxes in the floor. I could=20 also have used direct boxes (probably a better solution in retrospect.)=20 But there are only 4 mic inputs in a stage box, and I wanted to use one=20 for a monitor send. It was just a choice with unforeseen consequences. I=20 should have tried the whole rig together beforehand. I'm confused about your comment about mixing them together. I ran them=20 into separate channels at the mixer end.....I just used the balanced=20 microphone cables as two channels with a common ground. I am at a loss=20 to figure out why impedance would have any affect on that. Unless the=20 low side line inputs at the mixer are not actually common. Which I find=20 hard to believe. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
