Mbox Pro+Eleven rack via SPDIF doesn'work

[Oscar Soto]

OOhhhh gosh, my
bad streak does not end.

Well, I have a little issue, and I want to share with you, if anyone can help me I'll be so grateful.
Well, I usually use an Eleven rack with a DIGI002 via SPDIF+ PT11, and now, I want to do the same connection with a MBOX PRO, but that interface doesn't work well, I've changed the clocks master and slave between them but the Eleven rack change the external of clock show and says "Ivalid or none" or "Valid".... this doesn't happen with DIGI002, now I have digital noise, and obviously, I don't have signal at pro tools.
Does anybody know how can I fitx it?

Why do you need to slave the Eleven Rack from your interface? Do you have two S/PDIF cables connected both ways?

Do the simplest thing first. Connect one cable from the Eleven Rack S/PDIF Out to the interface S/PDIF In, and get that working.

Set the Eleven Rack clock to internal and set your interface to clock from it.

Are you using digital 75 ohm cable. Test with another cable.

Double check you are using the correct sample rate everywhere.
