USING AUDIO OUTPUT
Dolby® Digital gives you the capability to enjoy program audio in surround sound. An
external decoder is required to enjoy this feature. Refer to your decoder’s user’s guide.
Note: Not all programs or events contain a Dolby Digital sound track.
Your new 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/PCM: Select this option only if the stereo system or amplifier can both
decode Dolby Digital and also support Linear PCM digital signals.
• PCM Only: Select this option only if the stereo system or amplifier cannot decode
Dolby Digital 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 for a program or event, 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-only left/right stereo 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.
