& UL2Cin
The DTS THX UL2Cin (ULTRA2 CINEMA) and DTS-ES THX listening
modes allow 7-channel playback of 5.1-channel DTS sources. They
are designed for playback of 5.1-channel DTS, 5.1-channel matrix
encoded DTS-ES, or 6.1-channel DTS-ES discrete encoded film
sources. DTS THX UL2Cin and DTS-ES THX are recommended for
home theaters with THX certified speakers. These modes apply:
• 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.
• THX timbre matching to minimize timbre differences between
the front and surround channels, which results in smoother
sound movements between them.
The listening mode name differs depending on the encoding present
in the input source, the ES DECODING parameter setting, and the
speaker setup.
The DTS THX UL2Cin listening mode
The DTS THX UL2Cin listening mode is available when both side and
rear speakers are present and THX Ultra2 decoding is activated.
To activate DTS THX UL2Cin decoding:
1. Press MODE ADJUST DECODING.
2. Use the or arrow to select either AUTO (the default) or OFF.
When the ES DECODING parameter is set to OFF, the DTS THX
ULTRA2 listening mode is always active. When the parameter is set
to AUTO, the DTS THX ULTRA2 listening mode activates when a
5.1-channel DTS source is detected.
When THX UL2Cin decoding is activated:
• Adaptive de-correlation is applied 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.
• ASA processing is applied to signals sent to the rear speakers.
Refer to the ASA parameter description on page 3-37 for more
information.
The DTS-ES THX listening mode
The DTS-ES THX listening mode is available when both the side and
rear speakers are present and DTS-ES decoding is active.
DTS-ES decoding is activated when the ES DECODING parameter is
set to AUTO (the default) or ON and a 5.1-channel matrix encoded
or 6.1-channel discrete-encoded DTS-ES source is detected.
The table on the next page shows the conditions for the behavior of
the DTS THX UL2Cin and DTS-ES THX modes when activated:
