    Preface Great, that you have expanded your TerraTec AudioSystem with the capacity to process Word- Clock and SuperClock Signals. The EWS ClockWork not only allows you to externally synchro- nise an EWS with EWS ® -Connect connection, it can also function as the central clock for your entire digital studio.

  • Page 5 WordClock or SuperClock? The serial transfer of digital audio data was already standardised by the AES (Audio Engineer- ing Society) in the mid-eighties and dictates as such a 64 bit basic word width per stereo sam- ple. Irrespective of the original word width (e.g. 16 bit) 32 bit is to be transferred for each mono sample.
  • Page 6 Versatile range of applications If you wish to synchronise your digital studio by means of a central clock, you must first desig- ® nate one device as master. This may be any EWS card in the PC fitted with an EWS -Connect connection, but also an external digital device such as e.g.

  • Page 8 1. Master: EWS Master Card The concept "EWS Master Card" does not prescribe the card as the Clock-Master of the entire internal and external Systems. Only when the Master-Clock is to be generated via an EWS- ® System, will the EWS-Master card also be the Clock-Master. All other EWS cards with EWS Connect connection are basically operated in slave mode.
