Old AP Audio Patchbay

[punkin]

I have this old AP Audio patchbay and I've lost the destructions. The channel modules have 4 1/4" connectors (2 front, 2 rear), one of the 4 connectors is grey.

Anyone with a chart or information on how normal, half-normal etc is set up on this thing?



Thanks,
punkin
