hello, I recently bought a 1820 card emu, and I can not find some connections between physical / DSP entries. I have identified:
OUT 1L : EPILOG 0
OUT 1R : EPILOG 1
OUT 2L : EPILOG 4
OUT 2R : EPILOG 5
OUT 3L : EPILOG 6
OUT 3R : EPILOG 7
OUT 4L : EPILOG 8
OUT 4R : EPILOG 9

IN A : PROLOG 0
IN B : PROLOG 1
[edit] IN 1L : PROLOG 2
[edit] IN 1R : PROLOG 3
IN 2L: PROLOG 4
IN 2R: PROLOG 5
[edit] IN 3L : PROLOG 6
[edit) IN 3R : PROLOG 7

I seek the SPDIF input. it is also possible to recover an optical spdif signal or ac3 through adat connections?
thank you for all your help.
