Sounds like you need to understand the routing capabilities of the unit. I would suggest that you study the factory routings on the unit and in the manual.
For example, if you load "Thru" into both A and B, "Analog A->B" (UM p.26) will send analog 1/2 out S/PDIF1/2, while "AES8 A->B" (UM p.27) will send Analog 1/2 out S/PDIF3/4.
You may also find the Routing Utility (see H8000 Support pages) useful. Alternatively, if you tell me EXACTLY what you are trying to do, I can tell you how to set it up.
