Using Dolby® Digital Audio Output

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 owner's
manual for more details on its decoding (and see the following table).
• PCM Only: Select this option only if the audio system or amplifier cannot decode
Dolby Digital audio signals.
• Dolby Digital/PCM: Select this option only if the audio system or amplifier can decode
both Dolby Digital and Linear PCM audio signals. This is the default output option.
The audio output is also dependent on what is present in the program that you are
watching. The table below shows what type of output you will hear::

Dolby Digital Only
PCM Only
Dolby Digital/PCM
Note: When both audio signals are present in the program, the receiver always defaults to
using Dolby Digital output unless you have selected PCM Only in the Audio Output menu.
• 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
