5.1 MUSIC
• A proprietary listening mode.
• Based on the 5.1 L7 FILM listening mode, but specifically tai-
lored for music sources.
• Designed for playback of 5.1-channel Dolby Digital-encoded
music sources.
• Recommended for 5.1-channel Dolby Digital-encoded music
sources.
See “Listening Mode Menu Option & Parameter Descriptions” on page 5-29 for detailed
descriptions
.
, ULTRA2, & SUREX
• Designed for playback of 5.1-channel Dolby Digital film
sources.
• Listening mode name differs depending on the encoding
present in the input source, the SURROUND EX parameter
setting and the speaker setup. The table on the next page
indicates the conditions in which THX Surround EX and THX
Ultra2 decoding are engaged.
• Allows 7-channel playback of 5.1-channel Dolby Digital
sources without Surround EX encoding.
• 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.
• When the THX ULTRA2 listening mode is activated, ASA pro-
cessing is applied to signals sent to the rear speakers. Refer to
the ASA parameter description on page 3-32 for more infor-
mation.
• When the THX ULTRA2 listening mode is activated, adaptive
de-correlation increases the perceived width of the listening
space. De-correlation of the mono surround channel
increases the perceived width of the surround field in home
theaters.
• When the THX SurEX listening mode is activated, matrix
decoding derives three surround channels from 5.1-channel
Dolby Digital sources.
• Recommended for home theaters with THX-certified speaker
setups.
