• ASA (Advanced Speaker Array) – ASA is a proprietary THX technology that processes the sound
fed to the two surround and two rear speakers to provide an optimal surround sound experience.
When you set up your home theater system using all 7.1 speaker outputs (L-Front, Center, R-Front,
R-Surround, R-Rear, L-Rear, L-Surround, Subwoofer), placing the two Rear speakers close together
will provide the largest sweet spot. If for practical reasons you have to place the Rear speakers
further apart, you will have to go to the Listener Position menu (section 7.4.3) and choose the setting
that most closely corresponds to the speaker spacing to re-optimize the surround soundfield.
ASA is only used in two THX modes; THX Ultra2 Cinema and THX MusicMode (see below).
Depending on source material and speaker configuration, available THX Modes are as follows:
THX Cinema: 5.1 output with Stereo or Dolby Pro Logic
5.1 output with 5.1 Movies – DD-5.1, DTS-5.1
Processing: Re-Equalization, Timbre Matching, Adaptive Decorrelation
5.1 output with Dolby Pro Logic II-Movie
Processing: Re-Equalization, Timbre Matching
6.1 output with Neo:6 Cinema
Processing: Re-Equalization, Timbre Matching
Note: THX Cinema is the only THX mode available for use with Stereo or
Dolby Digital 2.0. When THX Cinema is ‘On’, Dolby Pro Logic II-Movie is
automatically engaged. Alternatively, Dolby Pro Logic or DTS Neo:6-Cinema
may be selected for use with THX Cinema. Other Surround Modes are not
available and do not appear when pressing MODE.
THX Ultra2 Cinema: 7.1 output with 5.1 Movies – DD-5.1 or DTS-5.1
Processing: Re-Equalization, Timbre Matching, Adaptive Decorrelation, ASA (Cinema)
THX Ultra2 Cinema mode plays 5.1 movies using all 7.1 speakers giving you the
best possible THX movie watching experience with 5.1 program material. In this
mode, ASA processing blends the L/R-Surround speakers and L/R-Rear speakers
providing the optimal mix of ambient and directional surround sounds.
THX MusicMode: 7.1 output with 5.1 Music – DD-5.1, DTS-5.1, DVD-Audio, multichannel SACD
Processing: Timbre Matching, Adaptive Decorrelation, ASA (Music)
THX MusicMode can be selected when playing multi-channel music. In this mode
THX ASA processing is applied to the surround channels of all 5.1 channel
encoded music sources to provide a wide stable rear soundstage.
Note: THX Ultra2 Cinema and MusicMode are for 5.1 material only – they do
not work with Stereo or program material encoded in Dolby Surround.
