3.6 DIGITAL/ANALOG AUDIO MODE
In digital satellite technology audio and video are generally transmitted in digital form (MPEG
coded). Where the term "Analog Audio Mode" is used in this section, it means that the digital
signals are converted into analog audio signals in the unit and are made available in analog form
at the "Left" and "Right" cinch sockets and also at the TV and VCR Scart sockets.
In "Digital Audio Mode" on the other hand the signals are transmitted to appropriate terminals,
such as a Dolby Surround System, for decoding in digital form via the "digital" cinch socket.
Either two-channel stereo signals (coded in
PCM
format) or complex multi-channel surround
signals (Dolby digital/
AC-3
) can be transmitted at the digital socket.
Press key
A
to display the "Digital/Analog Audio Mode" menu. You can use this menu as an
information display and immediately exit from it again by pressing key
A
again - or change
various settings.
Analog outputs:
In the right-hand window you can see the current signal status of the pins at
the rear of your satellite receiver.
You receive an analog audio signal at the cinch sockets and via the TV and
VCR Scart sockets.
Occasionally bilingual broadcasts are transmitted using the two stereo
channels "Left" and "Right". In this case you would hear e.g. "German" from
the left-hand and "English" from the right-hand loudspeaker. To hear just one
language, use the
+
(or
*
) key to select "Mono-L" or "Mono-R" and confirm
your selection with the
OK
key. The current selection has a white background.
Most bilingual or multilingual broadcasts however are transmitted using
separate audio tracks. In this case e.g. German would be displayed under 1
and English under 2 in the left-hand window, both languages being audible in
stereo sound. Use the
9
or
8
keys to select the desired language and
confirm your selection using the
OK
key. The language (or audio track)
currently selected has a white background.
The stereo display in the figure below means that only one language is being
transmitted in stereo. The content of the left-hand window is set by the
transmitting station - e.g. "German" or "ger" could be displayed in line 1 of the
left-hand window instead of "Stereo".
Digital output:
In the lower right-hand window you can see the current signal status at the
digital output ( = digital cinch socket).
If "
PCM
" is displayed, then the digital signal is coded in PCM format.
If "
AC-3
" is displayed, then the digital signal is coded in Dolby digital format.
Use the
8
or
9
keys to select, if available, the desired language or audio
track in the left-hand window and confirm your selection with the
OK
key. The
audio track currently selected has a white background.
The number of languages and audio tracks available is preset by the channel
provider.
A PCM-coded language or audio track is always displayed. But two or more
PCM-coded languages or audio tracks with one or more AC-3-coded
languages or audio tracks may also be available.
