• When the DTS THX ULTRA2 listening mode is activated, ASA
processing is applied to signals sent to the rear speakers. See
“ASA” on page 3-32 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.

• 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
setting 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
without 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.
