External Synchronization
External Synchronization (Connection via W/C-AES
SYNC INPUT) is required when several signals must be
brought together within a chain of digital units, e.g.
when connecting several digital units at one console.
Since the sample frequencies are never exactly iden-
tical, not synchronized sample rates inevitably have
different timings - samples are ignored or read twice,
usually audible als cracking.
By supplying all signal sources with a common
frequency, all signals are synchronized and sample
faults are avoided.
The common frequency can either be transmitted
via unbalanced coaxial wiring using a BNC/CINCH
adapter as Word/House Clock or as AES data if
connected as shown in the graphic below. In both
cases the WC/AES SYNC INPUT is to be used.
