•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.

When THX Surround EX decoding is engaged:

•Applies matrix decoding to derive three surround channels from 5.1-channel Dolby Digital sources.
