Lexicon MC-4, User Manual

Page: 105 / 164

5-7
PL +
• Designed for playback of Dolby Surround-encoded sources.
• Decodes four channels from Dolby Surround-encoded
sources.
• Uses a mono surround channel with a high-frequency rolloff
above 7kHz.
• 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.
