5.1 THX, 5.1 THX ULTRA2, & 5.1 THX 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 5.1 THX ULTRA2 listening mode is activated, ASA
processing is applied to signals sent to the rear speakers. Refer
to the ASA parameter description on page 3-34 for more
information.
When the 5.1 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 5.1 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
loudspeakers.
