& UL2Cin

MODE ADJUST OR 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 3-37for 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.
