PLIIx MUS & PLII MUSIC
Dolby Pro Logic IIx technology is an extension to Dolby Pro Logic II
that enables the listener to experience natural and seamless 6.1- or
7.1-channel surround sound from any native two-channel (stereo)
source. The PLIIx listening mode is only available when the front, side
and rear speakers are present. The PLII listening mode is available when
the front and side speakers are present.
Note:
The PLIIx MUS mode does not appear in the list of available listening
modes if either the side or rear speakers are missing from the configuration.
See page 5-35 for detailed parameter descriptions.
PL +
This mode is designed for playback of Dolby Surround encoded
sources and decodes four channels: three front channels and one
mono surround channel with a high frequency rolloff above 7kHz.
This mode is recommended for home theaters with THX-certified
speakers.
Dolby PL + THX mode:
• Applies THX re-equalization to simulate high frequency rolloffs
that occur in movie theaters. Most films are mixed for movie
theaters, and may sound too bright when played back in home
theaters without re-equalization.
• Applies THX timbre matching to minimize timbre differences
between the front and surround channels, which results in
smoother sound movements between them.
See page 5-35 for detailed parameter descriptions.
