And what about clocking? One of the devices must be master, the rest of devices slaves. You may distribute clock using ADAT, no need for worldclock.

I have Eclipse, but not Behringer. ADAT works fine with RME DigiFace USB.

(The only problem I hit on Eclipse is SPDIF via RCA. Maybe it works an I had wrong cables or whatever…..  But AES/EBU works fine, so no real problem SPDIF seems not work for me.)
