The clock master in my case is my MOTU 828ES

I sm sending clock via AVB to an AVB Switch. That feeds my MOTU 10Pre. The 10pre WC OUT is set to THRU and connected to the 112D which is also connected to the AVB Switch, Finally, the WC OUT of the 112D is sent to the H9000. Only the H9000 is terminated. I wanted an AVB expansion card for the H9000, but Eventide said no. That decision cost me an extra £1050 for the 112D.

I also have an Apogee Big Ben, but my BNC cables are not long enough…

Last of all, I have a TC Finalizer connected vis SPDIF to and from the MOTU 828ES without any wordclock cable between them.

Do I even need any wordclock/BNC cables at all?
