Sound Performance Lab 2053 manual External Synchronization

Operation

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.
