My first DA7. I have one ADAT card in slot 2 Running to an RME Digiface (old PCI version). Samplitude DAW. I will be using the preamps on the DA7. Have the RME set to clock from ADAT in. Card is showing UNLOCK. Any tips or tricks I'm missing?

The DA7 came with 3 cards installed:
Slot 1 AES
Slot 2 ADAT
Slot 3 AD/DA
