Using the System
Using Dolby® Digital Sound
Dolby Digital gives you the capability to enjoy programs in surround sound. An
external decoder is required to enjoy this feature. Refer to your decoder user’s
guide.
Note : Not all programs contain a Dolby Digital sound track.
The receiver uses an optical port for outputting digital audio. The optical output
can provide two audio data types: Dolby Digital and Linear PCM (only Dolby
Digital can provide full 5.1-channel sound).
1. Connect an external Dolby Digital decoder to the receiver's back panel
Digital Audio Output using an optical cable (available at consumer
electronics stores).
2. Press MENU-6-7 to open the Dolby Digital screen.
3. Select one of the following optical output options:
• Dolby Digital/PCM - Select this option only if the stereo system or
amplifier can decode both Dolby Digital and Linear PCM signals.
• Dolby Digital Only - Select this option if the stereo system or amplifier
can decode only Dolby Digital and will not process Linear PCM
signals. See your amplifier's owner's manual for more details on the
amplifier (and see the following table).
• PCM Only - Select this option only if the stereo system or amplifier
cannot decode Dolby Digital signals.
4. Select Done .
