I can't directly answer your question, but maybe the following will help. If you look at Page 110 of the Casablanca II Owners Manual, you'll find reference to eighteen (18) possible configurations for the four (4) "unmarked" Casablanca II Extreme Dac outputs.
If you then look at Page 9 in the on-line "Theta Digital Training Manual" you'll find that Page 9 lists twenty-five (25) possible configurations for the four (4) Casablanca III "unmarked" Extreme Dac outputs.
You'll also notice that each of the 25 possible configurations are named, e.g. A4-a. Accordingly, you might want to look at your board to see if your board is inscribed with one of the listed configurations.
