I have been struggling with trying to get a digital signal to the d8b from my MOTU 2408. The card in the back of the d8b that I am plugging into has an input for TDIF and adat and sync. Is this the correct card or do I need a card that just has optical/Adat. I could always try just the TDIF in this card but I don't have one of those cables yet. Any wisdom on this subject would be greatly appreciated.
Thank you,
Paul
