Multichannel Signal
The multichannel signal menu item describes what (if any) further
processing you would like to have applied to a discrete multi-
channel signal such as Dolby Digital 5.1, DTS 5.1, AAC 5.1 or MPEG
5.1, when you are in this particular sound profile.
When receiving and decoding a multichannel signal, allowable
surround modes depend on the number of back speakers you have
defined and the particular input signal being decoded. The
following surround modes are available.
•Downmix (2ch)
Downmix the multichannel signal to a 2-channel signal for
reproduction on the left and right front speakers.
• Multichannel
Signal passes through with no processing.
•THX Cinema
Engage THX processing for movies.
• Surround Plus
This surround mode is only available if there are one or two
surround back speakers defined. If there is one back speaker,
then it gets a scaled sum of the surround channels (sl or sr). If
there are two back speakers, the left surround back speaker gets
a scaled version of the left surround and the back right speaker
gets a scaled version of the right surround. It is not available for
six channel streams (Dolby-EX or DTS-ES).
• Surround Plus + THX Cinema
Add THX cinema processing to above.
• Surround Matrix
Use DTS NEO:6 matrix processing to create surrounds and back
channels from the surround left and surround right channels. It
requires one or two back speakers.
• THX Surround EX
Use Dolby Pro Logic II matrix processing to create the
surrounds and back channels from the surround left and
surround right channels. Add THX cinema post processing. If
the multichannel signal is DTS, then DTS NEO:6 is used instead
