[. . . ] 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. 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. a sequencer program (Emagic Logic, Steinberg Cubase VST, etc. ), often have various sample rates then the EWS-Master Card in the PC should be designated as Clock-Master. Your entire digital system (including all external equipment) will be set to the appropriate frequency each time you switch to play mode. Some devices may, however, cause problems and will consequently refuse audio processing if there is no external clock connected, e. g. In this case the external device is to be designated master and the sample rate is to be set. A further feature of the EWS ClockWork is the possibility to include external devices which have no BNC connections for a Word / SuperClock Signal in the synchronisation. Should a DAT recording for instance be transferred to the PC where the DAT recorder does not have a Word or SuperClock connection, the S/PDIF source may be designated master. If the EWS-Master Card is an EWS88 D then this also holds for the ADATTM signal. 6 SyncXtension EWS ClockWork (English) Dip switch settings OFF ON O N 1234 Switch OFF ON Format WordClock SuperClock Source External Internal S/PDIF W. -/S . -Clock S/PDIF Term.

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). Should you operate an external device in this operation mode via the S/PDIF Interface of the EWS-Master card, please remember that this device can only be synchronised in record mode. In play back mode, an S/PDIF device without Word / SuperClock connection only functions according to its own internal clock generator. Even if the sample rate of the S/PDIF device corresponds with that of the Clock-Master the sources will nevertheless run unsynchronised which will result in distortions during play back. In such case it is adviced to choose the mode "Master: External S/PDIF (ADATTM) IN" described on the following pages. 8 SyncXtension EWS ClockWork (English) Master: EWS Master Card C N1 S nc-IN L in k* y t o Sla v 2 S y In e nc to S lave 3 Sync I n EWS88 D (Slave 1) J4 -J 6 to Sl ave 1-3 Sync-I N J7 to Master S y nc-OUT J3 to Master Syn c I n Digi tal I/O O UT IN MASTER Clock Source C N Sy nc -OUT L ink 2 CN1 Sync -IN L i nk EWS88 MT (M aster) E WSC lo ckWork S /PD IF L in k DAT D AT-Recorde r E-Kai Digital Mixer Sa mpl er * Please note: The Hardware-Revision 1. 0 of the EWS88 D contains a deviant labelling of the pin strip.

If the EWS-Master Card is an AudioSystem EWS88 D then this also holds for the ADATTM 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. 12 SyncXtension EWS ClockWork (English) Master: External S/PDIF (ADATTM) IN C N1 S nc-IN L in k* y t o Sla v 2 S y In e nc to S lave 3 Sync I n EWS88 D (Slave 1) J4 -J 6 to Sl ave 1-3 Sync-I N J7 to Master S y nc-OUT J3 to Master Syn c I n Digi tal I/O O UT IN C N Sy nc -OUT L ink 2 CN1 Sync -IN L i nk EWS88 MT (M aster) E WSC lo ckWork S /PD IF L in k DAT MASTER Clock Source D AT-Recorde r E-Kai Digital Mixer Sa mpl er * Please note: The Hardware-Revision 1. 0 of the EWS88 D still contains a deviant labelling of the pin strip Here, the 5-pole Sync IN has been labelled CN2 and the 3-pole Sync OUT CN1.
