The manual talks about wordclock BNC termination.Currently I have no termination when trying to use the BNC wordclock cable as the timing source from the RME Multiface to the Eventide. Could the lack of termination be a reason why I get this anomoly when using ADAT? 

 I currently have a 75ohm cable. Am I correct in my understanding in the manual that I should use a 50ohm terminator at the end of the chain, in this case, the h8000fw?
