THX Features

The SSP80 and SSP100 include a THX
processing mode to enhance your audio
experience of film soundtracks.
THX is an exclusive set of standards and
technologies established
renowned film production company,
Ltd
. THX grew from a desire to make your
experience of the film soundtrack, in both
cinemas and in home theaters, as faithful as
possible to the director's intention.
A film soundtrack is mixed in a special cinema
called a dubbing stage, and is designed to be
played back in large cinemas with similar
equipment and conditions. The soundtrack is
then transferred directly onto Laserdisc, VHS
tape, DVD, and so on. It is not changed for
playback in a small home theater, and
because of this tonal and spatial errors can
occur. THX engineers developed the patented
THX technologies to accurately translate the
sound from the cinema environment into the
home, to correct these errors.
THX cinema processing features include:
•

re-equalization

timbre matching

Re-equalization
The tonal balance of a film soundtrack is
excessively bright and harsh when played
back over audio equipment in the home.
Re-equalization restores the correct tonal
balance for listening to the soundtrack in a
small home theater.
Timbre matching
The human ear changes our perception of a
sound depending on the direction the sound
is coming from. In a cinema, there is an array
of surround speakers
information is all around you. The timbre
matching feature filters the information going
to the surround speakers so that they more
closely match the tonal characteristics of
sound coming from the front speakers in a
cinema. This ensures
between the front and surround speakers.
Adaptive decorrelation
In a cinema, a large number of surround
speakers helps create an enveloping surround
sound experience, but in a home theater
there are usually only two speakers. This can
make the surround speakers sound like
headphones that lack spaciousness and
envelopment. The surround sounds also
collapse into the closest speaker as you move
away from the middle seating position.
