ULTRA2 &
• Designed for playback of 5.1-channel DTS, 5.1-channel
matrix-encoded DTS-ES and 6.1-channel discrete-encoded
DTS-ES film sources.
• Listening mode name differs depending on the encoding
present in the input source, the ES DECODING parameter set-
ting and the speaker setup. The table below indicates the
conditions in which THX Ultra2 and DTS-ES decoding are
engaged.
• Allows 7-channel playback of 5.1-channel DTS sources with-
out DTS-ES 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 DTS 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 3-37 for more
information.
• When the DTS 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.
• Recommended for home theaters with THX-certified speaker
setups.
