Co-Axial Digital Interface; General - TerraTec EWS88 MT Manual

Co-axial digital interface.

The co-axial plug (Cinch-plug) connects to instruments, which send
and/or receive S/PDIF-signals and RAW-data. This includes DAT-
recorders, digital amplifiers or MiniDisk. In addition to 24-bit it will
also transmit traditional 16-bit signals.

General.

Recording and playback of digital audio is taken care of by the connectors on the backplate of
your PCI card. For this purpose, you have two RCA-type connectors. The AudioSystem EWS88
D also allows you to use the optical ADAT-connector for transmission and reception of S/PDIF-
signals. (Please refer to page 37.)
Using the ADAT-connection for recording, you need to ensure that the sampling frequencies of
both are identical. To guarantee perfect synchronization you must switch the masterclock
setting in the ControlPanel to "External" .
EWS88 only transmits audio data which are identical to the receiving machine. But here also
special cases are to be taken into consideration: Digital mixing desks (i.e. Yamaha 02R), do not
transmit any audio data when there is no external synchronization present (i.e. when your PC
is switched off).
The suitable drivers for digital ADAT-recording are "EWS88 WaveRec S/PDIF". As up to 8 audio
channels can be received, the drivers are grouped in pairs (1/2, 3/4, 5/6, 7/8). You can find
more information on the drivers from page 48, detailed information on the ControlPanels
settings from page 53.

Skipping this important step may result in audible
dropouts in the recording. Of course the external
instrument must be switched to the appropriate
setting as well. If you intend to connect both
instruments in both directions permanently, you must
decide on a common synchronization format. Which
format is most suitable for your studio, can only be
decided by yourself. You need to consider, that – for
safety reasons – when synchronized externally, the
