Using Dolby® Digital Surround 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).
• 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.
• Dolby Digital/PCM - Select this option only if the stereo system or amplifier can decode both
Dolby Digital and Linear PCM signals.
The audio output is also dependent on what is present in the program you are watching. The table
below shows what type of output you will hear:
Note: When both audio signals are present in the program, the receiver defaults to Dolby Digital
output unless you have selected PCM Only.
Note: If you have selected Dolby Digital Only but there is only PCM audio in the program, you will
hear nothing. This also applies to the analog audio outputs.
• Line Mode. When you use this setting, in comparison to RF Mode, the dynamic range is
wider, which makes the music and loud noises louder, but voices quieter.
• RF Mode. When you use this setting, in comparison with Line Mode, the dynamic range is
narrower, which makes music and loud noises quieter, but voices louder.
