Module 2 Confi guration Download
OFF
Standard operation (factory default)
ON
Confi guration download via RS232
If
fi rmware download to decoder module 2 is required, plug the short fl at
cable (W1) coming from the
METADATA OUT
front-panel socket to the
PCB socket P8 (labeled UPDATE2).
The pin assignment of the
METADATA OUT
socket
(9pin D-type, female, UNC
4-40 thread)
in this case is as follows:

Metadata and Downmixing:
A Dolby
®
E stream contains metadata with
various information on the encoded signal. This information can be read
out from the front panel connector. The D21m Dolby
®
E decoder card only
uses this information in case a 2-channel stereo downmix is required from
a 5.1-channel surround signal within the Dolby
®
E stream; then the decoder
interprets the center and surround channel levels and uses them for the internal
downmixer that is activated by the DIP switches S1.7 and S1.8. The downmix
can be made constantly available and, subsequently, overwriting any audio
data that was contained on these channels beforehand (“forced downmix”), or
it is possible to “fi ll” the channels 7/8 or 15/16 only if the metadata indicate
that these channels are not being used otherwise (automatic downmix).
