I have found this before but I have lost the link.
Does anyone have a link that lists out the various connectors (1/4" & 6,3mm, 1/8" & 3,5mm, XLR 3-pin, etc.) their various configurations and pin wiring? For example, 3.5mm TRRS wired with mic versus 3.5mm wired for balanced.
As I said, I had a URL which did an excellent job listing the various connectors and most common configurations with color coded diagrams. I neglected to bookmark the site and I cannot find it again.
