ULTRA2
OR
•
Designed for playback of 5.1-channel Dolby Digital film
sources.
•
Allows 7-channel playback of 5.1-channel Dolby Digital sources
without THX 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.
•
Recommended for home theaters with THX-certified speakers.
When THX Ultra2 decoding is engaged:
•
Applies adaptive de-correlation to increase 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.
•
Applies ASA processing to signals sent to the rear speakers.
Refer to the ASA parameter description on page 3-31 for more
information.
