of Dolby Pro Logic II and the mode is called Surround Plus +
THX Cinema. One or two surround back speakers are required.
• THX Ultra2 Cinema
Use THX Advanced Speaker Array technology to create the
Surround and Back channels from the surround left and
surround right channels. Add THX cinema processing including
RE-EQ, Timbre Matching and Adaptive Decorrelation. Two back
speakers are required and it is not available for six channel
streams (Dolby-EX or DTS-ES).
• THX Music Mode
Uses THX ASA processing to provide a wide stable rear sound-
stage for multichannel music. Two surround back speakers are
required and it is not available for six channel streams (Dolby-
EX or DTS-ES).
• Surround Redirect
The surround channels are sent to the surround back speakers
and the primary surround speakers are turned off. Two
surround back speakers are required and it is not available for
six channel streams (Dolby-EX or DTS-ES).
If the input stream is a Dolby encoded stream with the EX flag set
indicating that it contains back channel information, THX
Surround EX mode will be automatically engaged and your choices
will be limited to Downmix, Surround Matrix or THX Surround EX.
If the input stream is a DTS encoded stream with the ES flag set
indicating that it contains back channel information, it will default
to Multichannel or THX Cinema depending on whether a THX
mode was indicated in your profile. Manual setting choices will
then be limited to Downmix, Multichannel or THX Cinema.
If the input is a six channel analog input or DTS 96/24, the
Surround Matrix mode and all THX modes cannot be used. If an
invalid mode is called for in the profile, its closest valid mode will
be selected automatically. If the invalid mode contained back
channel information, the new mode will be Surround Plus. If not,
the new mode will be Multichannel.
2 channel signal This menu item describes any further processing you would like to
apply to a two channel signal such as 44.1 kHz PCM from a CD,
Dolby Digital 2.0, or MPEG 2.0, when you are in this particular
sound profile.
There are significantly more options available for processing most
two-channel signals than for processing multichannel signals. This
makes sense when you think about it, since most of the options for
two channel signals are different ways of processing the two
channels to use most or all of your speakers.
