DTS Digital Surround
DTS Digital Surround is a digital surround format developed by
Digital Theater Systems of the United States.
The number of playback channels and the playing band is the
same as for Dolby Digital (5.1 channels).
The compression rate of the audio data when it was recorded
on the medium is lower than for Dolby Digital, so there is
more information when the data is decoded, resulting in
richer, clearer sound quality.

DTS-ES™
DTS-ES is a new surround format developed by Digital Theater
Systems.
A sound image and sense of positioning can be achieved by
adding a surround back (“SB”) channel to the conventional 5.1
channels.
DTS-ES™ Discrete 6.1:
This is the latest format, in which all 6.1 channels, including
the “SB” channel, are recorded independently. Since the
different channels are independent, the sound can be
designed with total freedom.
DTS-ES™ Matrix 6.1:
With this format, the “SB” channel is matrix-encoded and
inserted into the “SL” and “SR” channels, then decoded for
the “SL”, “SR” and “SB” channels upon playback. This
achieves a surround sound more faithful to the artist’s sound
design intentions than with conventional 5.1 or 6.1 channel
systems.
DTS 96/24
DTS 96/24 is a multi-channel digital signal format developed by
Digital Theater Systems.
The sampling frequency is raised to achieve 5.1 channel
playback with high quality sound (sampling frequency: 96 kHz,
quantization: 24 bits).
DTS NEO:6 surround
This is a matrix decoding technology for 6.1 channel surround
playback of 2 channel sources.
The optimum decoding for the type of signal source to be
played can be selected. There are two modes.
DTS NEO:6 CINEMA:
This mode is suited for playing movies. It achieves the same
type of sound as in a movie theater, even with 2 channels.
DTS NEO:6 MUSIC:
This mode is suited for playing music. A natural sense of
expansion is added to the sound field.
Home THX Cinema Surround
THX is an exclusive set of standards and technologies
established by the world-renowned film production company,
Lucasfilm Ltd. THX grew from George Lucas’ personal desire
to make your experience of the film soundtrack, in both movie
theaters and in your home theater, as faithful as possible to
what the director intended.
Movie soundtracks are mixed in special movie theaters called
dubbing stages and are designed to be played back in movie
theaters with similar equipment and conditions. The
soundtrack created for movie theaters is then transferred
directly onto Laserdisc, VHS tape, DVD, etc., and is not
changed for playback in a small home theater environment.
THX engineers developed patented technologies to accurately
translate the sound from the movie theater environment into
the home, correcting the tonal and spatial errors that occur. On
the AVR-5805CI, when the Home THX Cinema mode is on,
THX post-processing is automatically added after the Dolby
Pro Logic, Dolby Digital or DTS decoder:
Re-EQ™ (Re-Equalization):
The tonal balance of a film soundtrack will be excessively
bright and harsh when played back over audio equipment in
the home because film soundtracks are designed to be
played back in large movie theaters using very different
professional equipment. Re-Equalization restores the correct
tonal balance for listening to a movie soundtrack in a normal
home environment.
