AudioSystem EWX 24/96
37
All three of these settings offer the following parameter options:
-
Copyright
adds a copyright mark or (by deactivation) filters it out. Hereby is the
so-called “Copy-Protection-Bit” set, which
doesn’t
allow the signal to be copied
on normal consumer devices.
-
Original
activates what is known as the “Generation-Bit” and only allows ex-
actly
one
digital copy to be made. If you deactivate this function - if the bit is
set to 0 – you are allowed to keep merrily making copies.
-
Non-Audio
adds information to the data stream that is recognized as “Non
audio” and so transfers raw data formats (like AC-3 / DVD audio, and others)
for playback.
When recording using the S/PDIF port, you need to pay attention that the sample rates
of both the card and the sending device are the same. To ensure an error free synchro-
nization to the external device, set the
MasterClock
in the EWX Control Panel to “Ex-
ternal”.
If you forget this step, then among other things, you
will hear errors (drop-outs, popping) in your recordings
as a result. And also vice versa (an external device
should be synchronized with the EWX 24/96) you
need to make the corresponding settings to your pe-
ripheral devices. The EWX Control Panel then needs to
be set (as is during operation without connected external devices) to “Internal”. If you
have devices
permanently
connected in both directions then you have to decide which
end should determine the synchronization.
Keep in mind, that as a safety feature, the EWX 24/96 only plays audio signals syn-
chronized externally if the signal sample rate corresponds to the settings (for example
no WAV files can be played with 22,05 kHz, while the Minidisk recorder is set at
44,1 kHz). But also in the other direction there are things to consider: There are de-
vices that, failing the external synchronization (e.g. when the PC is shut off) or when
the sample rate is to high (e.g. higher than 48 kHz) simply refuse to play audio.
The EWX 24/96 digital ports transfer all bit resolutions between 8 and 24 Bit, as well
as all sample rates between 8 and 96 kHz. It is furthermore possible to use the ports
for standards other than S/PDIF. Several software DVD players (e.g. Power DVD, ver-
sion 2.55 or higher) support the playback of DVD audio material over the EWX 24/96.
This way signals such as Dolby AC3 or DTS format can be processed through the digital
ports. (Further information about Power DVD can be found at:
