Digital I/O - Selecting the S/PDIF Output Format
Gina24 can transmit digital information in either of two formats,
“professional” or “consumer.” The primary difference between the two is in
the implementation of the SCMS copy protection bit, which, in the
Consumer
format, prevents the user from making digital copies of a digital
copy.
Gina24’s S/PDIF output defaults to the
Professional
format. If you are
recording from Gina24 into a consumer DAT deck, the deck may not be
able to recognize the signal until you switch Gina24’s output to
Consumer
.
We have provided a software switch in the Gina24 driver that allows you
to select which format Gina24 transmits. In the window that appears you’ll
see a pair of check boxes in an area labeled
S/PDIF Out Format
: one box
is labeled
Consumer
and the other
Professional
. Select the appropriate
format for your DAT (if you don’t know which one to use and are having
difficulties, simply try the one that is not currently checked).
Important note: Gina24 never transmits the SCMS bit, regardless of which
format is selected.
Digital I/O - Dither Input
In the top right is a checkbox labeled
Dither Input
. This checkbox allows
you to enable or disable dithering on the digital inputs (S/PDIF & ADAT).
It is off by default. Most of the time you will want to leave this setting
disabled. The only time you will want to use dithering is when you are
receiving a 24 bit signal over the digital inputs, but you want to record it as
a 16 bit wave file. In this case, dithering will improve the audio quality.
