I have a microphone plugged into the XLR end of a cord, but the other end of the cord has a balanced 1/4" end that I plug into a PA. This seems to get a way lower volume than a normal XLR male/XLR female cord into the mic input of the PA. Why is this? And if the end was an unbalanced 1/4" instead of a balanced 1/4", would there be any difference? ALSO: Is there be a difference between an XLR/unbalanced cable and an XLR/XLR cable with one of those clunky 1/4" adaptors on the end? Thanks a lot for any info!
