Home THX cinema
THX is a creation of Lucasfilm Ltd., which practically brings the cinema
sensation to your home with its superb multichannel digital audio
program.
This system promises a reproduction of an enthralling home experience,
which is able to encompass smaller space with fantastic audio output.
In order to enjoy this function, an optimum speaker placement is
required.
THX includes Re-equalization (Re-EQ), Timbre Matching, Adaptive
Decorrelation, Bass Peak Level Manager and Loudspeaker Position
Time Synchronisation.
Re-equalization (Re-EQ)
When listening in a typical home room, there may be some variation of
echo due to air absorption and smaller space. The sound produced by
flat response loudspeakers normally used in the cinema can be overly
bright in the home environment. Thus, Re-equalization (Re-EQ) will
adjust this condition to fit the home environment for a similar cinema
effect.
Ambience effects
Dolby 3 Stereo
Dolby 3 Stereo is available for systems that do not have surround
speakers. When in the Dolby 3 Stereo mode, the surround information
is redirected to the front left and right speakers. This mode is designed
for use with Dolby Surround program sources, but can also improve
sound field unity for programs that are not Dolby Surround encoded.
Dialog positioning and sound image definition, however, may not be as
accurate when used with programs that are not Dolby Surround
encoded.
Timbre Matching
Due to human condition, listening to sound from various directions of
speakers can be very disturbing. So, it is important to smoothen the flow
of sound to suit the home cinema environment. Timbre Matching is able
to smoothen the flow of sound to the listener who will be able to enjoy
the cinema effect at home.
Adaptive Decorrelation
Mono sound track produced form the speaker system comes from only
one direction, which does not exemplify the cinema surround sound
experience. Adaptive Decorrelation is able to adjust the inaccuracy of
this sound distribution.
Bass Peak Level Manager
Certain sound tracks may produced various bass peaks that could
be unpleasant in a home cinema environment. Therefore, a user-
adjustable Bass Peak Level Manager is used to control the bass level
to suit the system’s capacity.

SRS Circle surround enables you to listen to multi channel sound from
the stereo source. We assume you have already enjoyed listening to
Dolby digital sound/DTS multi channel sound with your multi speakers.
Now, this time try listening to the stereo source (ex. Audio CD) using your
multi speakers. You may discover a new type of “stereo” sound through
SRS Circle Surround.
