Hi all. Trying to find a small digital router - scenario as follows.

I need to send and receive from/to MOTU 828MkII via RCA S/PDIF to Focusrite TwinTrak for tracking, but also want to use the S/PDIF to feed an external reverb on mixdown. It's to much effort to get behind the rack everytime to swop out the cables, so though of finding a router. I know Z-Sys make something that can do this, but it's way to big for what I need. Any other companies/ideas? It has to be on RCA as my ADAT is being used.

Thanks in advance
