MODE ADJUST 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.
