Ok, i've made some tests with 15m adat cable with my Focusrite octopre mk2, and i cant' have any synchronization with only ADAT and without bnc wordclock.
With a bnc wordclock, the problem is that the signal is ok from the octpre to the cards , but on the other way from the card to the octopre, I don't have any sound out (I use them for studio monitoring).
I'm waiting for 10m adat cables now

About BNC Wordclock
We use paralell sync with Mutec MC 7. ( See pic under Xite )
MC 7 is amplifying the BNC signal
Thats because we have so many ADAT
We use all ADAT very close to each other,
Because BNC is not as stable as Optical,
when using for example MADI,
For Wordclock we then of practical reasons
have all ADAT very close .
BNC cables only 1,5 m
The Mutec MC 7 is amplifying the BNC Wordclok sync,
but also all BNC Wordclock cables are made paralell.
Thats making the Wordclock Sync really stable.
You must use 15 m BNC and also ADAT that long.
I dont know what to answere .
We have so many mixers , but use only one.
Thats a monitor for the earphones.
Scope mixers has retiered them all.
We are now investigating in having three small,
summing mixers from SPL only, for 3 groups on our real drums .
For Wordclock sync Design ,
please call Thomann free telephone support.
They will give you all answeres ,without having to buy first.
