I'm not sure I follow you. The combo has 3 pins no? I'm not sure I follow you on why it would require 2 DB25s. How many DB25s would I need if I was connecting to a standard xlr neutrik, like the na3fdm?
check my comment above, I think it might help answer, maybe?
I'm trying to connect from my input plate (8ins) to my patchbay which is all DB25 connections
My powers of descriptions are awful, so I'm going to attach some pics to help me describe what I'm getting at.
Basically I want to have my 8 inputs connected to a DB25 that runs into my patchbay. Which would be easy enough if they were either XLR or TRS, since I could use a DB25 to XLR...
If I had a 8 input plate with 8 XLR/TRS combo neutriks (which all come open and requiring soldering) how would I be able to connect them to a DB25 Cable?
I know you can get a DB25 to XLR (or TRS) which splits off into 8 channels, but for each of the tendrils, the wire looks too narrow to cut...
