Rosettas into a behri?
well, weirder things have happened...
It also depends on the console, some are all digital (like a D5 etc) which would take an AES/EBU from the bit-collectors and then make a mix, other wise it's something like
Bit-Collector -> D/A -> Console -> output media
for mixing and
Pres -> mixer (inserts)-> < - A/D converters -> Bit collector
.....................................- Monitor/headphone mix
For tracking.
Alternativley, they could be useing (shock horror) tape, and hence it would be an analouge chain the whole way thorugh (the nerve of some people, I swear... don't they know we invented 0's and 1's for a reason?)
