apparently the answer is yes - connecting should work.
I use a TOSLINK cable to connect my Digimax D8 to my Studio 18/24 via ADAT.
(I made also my Studio 18/24 the primary for the clock using BNC cable, thus it is set to external on the Digimax D8)
That is the setup and how it is supposed to work.
However, I get no signal routed from the Digimax to Studio One via Studio 18/24. I must make a mistake therefore.
I would appreciate if one from the Forum/Support could also look into your question.
