Thanks for all the replies.

I have not been there, where the rig is since these replies came in. I've seen this unit listed as an option to utilize the spdif i/o but I can't seem to find an instance of it working in the duc.

For whatever reason, the unit doesn't yet give me the option to select a sample rate. There is a list of sample rates but none of them are selected and it will not let me select one. I have a feeling this might not be operating properly.

I did try to connect the word clock from the ada8000 and the ultramatch but it didn't change anything. In PTLE I have the clock source listed as the ADAT behringer unit.

As for the spdif/rca conflict, I am a little confused. I understand that RCA just represents the connector but from what I can tell a standard coax cable and a standard rca cable are very simular, coax is typically a larger gauge but they are both shielded.

I'm not using a coax cable but it is a high quality (large gauge) monster componet cable. I'll try something different tomorrow... does anyone have any experience with this unit or with componet vs coax rca cable.

Thanks again!
