Edited for clarity.

So here is the deal. I am in the patchbay/cable routing hell part of the whole studio build. I have decided to get a couple of Audiolot 192pt mixbays. I spoke with a gentleman about possibly getting the wiring and boxes in a bulk deal through Audiolot, but the price was a good deal out of my range.

I really need to find a schematic that explains wiring a db25 to xlr, I cant quite figure it out and theres no "standard" that relates the db25 to microphone connections, I'm having a hard time understanding the concept for the most part because there are 25 pins, how is this possible when a db25 digisnake terminates to 8 xlr? is one pin just not connected?

Where can one buy DB25 to XLR3 cables for Pro Tools. Also DB25 to pigtail ends.

Thanks

Larry
