PLII +
• Designed for playback of Dolby Surround-encoded sources.
• Uses Dolby Pro Logic II decoding to derive five channels from
Dolby Surround-encoded sources.
• Applies THX re-equalization to simulate high-frequency
rolloffs that occur in movie theaters. Most films are mixed for
movie theaters, and might 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.
• Recommended for home theaters with THX-certified speaker
setups.
See “Listening Mode Menu Option & Parameter Descriptions” on page 5-29 for detailed
descriptions .
PRO LOGIC

• Uses a mono surround channel with a high-frequency rolloff
above 7kHz.

mode.
