"Dolby Digital" output from the DIGITAL AUDIO OUT terminal
Some digital channels are broadcasted with "Dolby Digital" signals.
In these cases, "Dolby Digital" signals can be output from the DIGITAL
AUDIO OUT terminal.

Connect an audio system with a "Dolby Digital" decoder to the
DIGITAL AUDIO OUT terminal.
INSTRUCTIONS
g
"Connecting your external devices" (P. 9)
2
Change the "Digital Audio Output" setting from "PCM" to "Dolby
Digital". (P. 13)
When changing the setting, the message "Dolby Digital selected!
No analogue audio available" may be displayed for a few seconds.
Each time the channel is changed to a channel that is broadcast with
"Dolby Digital" signals, the message "Dolby Digital selected!
No analogue audio available" may be displayed for a few seconds.
Even if "Dolby Digital" is set, "linear PCM" signals will be output by a
channel that is not broadcast with "Dolby Digital" signals. Set the audio
system so that it is compatible with both "Dolby Digital" and "linear
PCM". (For details, refer to the audio system instruction manual.)
Set "Digital Audio Output" to "PCM" in the following cases.
The sound of a channel broadcast with "Dolby Digital" signals cannot be
heard even when "Dolby Digital" is set.
When listening with the TV speakers.
When listening with an audio system that does not have a "Dolby
Digital" decoder.
When listening with an audio system that is connected to the
AUDIO OUT terminal.
When recording a programme.
When "(Dolby)" is displayed in the "Audio Selection" menu (P. 5),
selecting "(Dolby)" will change the "Digital Audio Output" setting to "Dolby
Digital" temporarily.
A message recommending you to change the "Digital Audio Output"
setting to "Dolby Digital" is displayed for a few seconds.
If you want to record a "Dolby Digital" signal using timer-record (P. 10),
change "Audio" of the timer-record setting from "PCM / Analogue" to
"Dolby Digital". However, if the setting is changed to "Dolby Digital", you
cannot record analogue sound with a recording device that is connected
to the EXT-2 terminal.
