CE declaration We: TerraTec Electronic GmbH, Herrenpfad 38, D-41334 Nettetal, Germany hereby declare that the product: Sync Xtension EWS ClockWork to which this declaration refers complies with the following standards or standardizing documents: 1. EN 55022 2. EN 50082-1 The following are the stipulated operating and environmental conditions for the said compliance: Residential, business and commercial environments and small-company environments.
Preface Great, that you have expanded your TerraTec AudioSystem with the capacity to process WordClock and SuperClock Signals. The EWS ClockWork not only allows you to externally synchronise an EWS with EWS®-Connect connection, it can also function as the central clock for your entire digital studio. Moreover, the EWS ClockWork can be adjusted to a wide variety of demands.

WordClock or SuperClock? The serial transfer of digital audio data was already standardised by the AES (Audio Engineering Society) in the mid-eighties and dictates as such a 64 bit basic word width per stereo sample. Irrespective of the original word width (e.g. 16 bit) 32 bit is to be transferred for each mono sample. A WordClock Generator produces per stereo sample, a cycle whose frequency corresponds exactly with the actual sample frequency.
Versatile range of applications If you wish to synchronise your digital studio by means of a central clock, you must first designate 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. a digital mix pannel. You may decide which one will be given the master, but there are some things that should be taken into account: Should the audio files when played by means of a software application, e.g.

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 EWSSystem, will the EWS-Master card also be the Clock-Master. All other EWS cards with EWS®Connect connection are basically operated in slave mode. An exception is the "Independent" mode option on the ControlPanel of the EWS-Systems (for further information please refer to the manual of the EWS card).

2. Master: WordClock (SuperClock) IN If the Clock IN bus receives a good signal, both blue LEDs in the slot plate will indicate this (each for WordClock or SuperClock). If the EWS ClockWork Modul is last in a Word or SuperClock chain the termination will have to be activated by means of DIP switch 4. Switch 1 (WordClock / SuperClock switch) is idle in this mode since the module adjusts to the external Clock format present.

3. Master: External S/PDIF (ADAT™) IN The S/PDIF-IN of the EWS-Master card may function as central Clock source. If the EWS-Master Card is an AudioSystem EWS88 D then this also holds for the ADAT™ signal. In the event that multiple EWS-Systems are connected via the "EWS®-Connect" inside the PC, the external digitale IN of all slave cards will not function as Clock source and the respective button on the EWS ControlPanel will no longer be available.
