Quad 303a2 5 pin XLR outputs

The outputs of my 303a2 and the cabling colour codes I have assigned for identification (colour codes are nothing to do with original designations - just for my benefit). This is viewed from the CABLE side and not the pin side of the plug.

Pin 1    ground       no connection
Pin 2    low freq +  red
Pin 3    low freq  -  blue
Pin 4    high freq + green
Pin 5    high freq - black

This will be updated with Neutrik Speakon designations when I have done that modification
