■ DTS Digital Surround
DTS Digital Surround(also called simply DTS) is a multi-channel
digital signal format which can handle higher data rates. Discs
bearing the “ ” include the recording of up to
5.1 channels of digital signals, which can be generally thought
to provide better sound quality due to the lower audio
compression required.
It also provides wide dynamic range and separation, resulting
in magnificent sound.
■ DTS - ES Extended Surround™
( )
This is a new multi channel digital signal format which greatly
improves the 360- degree surround impression and space
expression thanks to further expanded surround signals,
offering high compatibility with the conventional DTS format.
In addition to the 5.1 channels, DTS-ES Extended Surround
also offers the surround back (sometimes also referred to as
“surround center”) channel for surround playback with a total
of 6.1 channels. DTS-ES Extended Surround includes two
signal formats with different surround signal recording
methods as follows:
• DTS-ES™ Discrete 6.1
Because the signals for 6.1 channels (including the surround back
channel) are fully independent, it is possible to achieve a sense
that the acoustic image are moving about freely among the
background sounds surrounding the listener from 360 degrees.
Though maximum performance is achieved when sound
tracks recorded with this system are played using a DTS -ES
decoder, when played with a conventional DTS decoder, the
surround back channel signals are automatically downmixed
to the surround left and surround right channels so that none
of the signal components are lost.
• DTS - ES™ Matrix 6.1
With this format, the additional surround back channel
signals undergo matrix encoding and are input to the
surround left and surround right channels beforehand. During
playback, they are decoded to the surround left, surround
right and surround back channels.
Because the bit stream format is 100% compatible with
conventional DTS signals, the effect of the DTS-ES Matrix 6.1
format can be achieved even with DTS 5.1- channel signal
sources. Of course, it is possible to play DTS-ES Matrix 6.1 -
channel signal sources with a DTS 5.1 - channel decoder.
When DTS-ES Discrete 6.1 or Matrix 6.1 sources are decoded
with a DTS - ES decoder, the format is automatically detected
upon decoding and the optimum surround mode is selected.
However, some DTS - ES Matrix 6.1 sources may be detected
as DTS sources. In this case, the DTS - ES Matrix mode
should be selected manually to play these sources.
� DTS Neo : 6™ surround
This mode applies conventional 2-channel signals such as
digital PCM or analog stereo signals to the high precision digital
matrix decoder used for DTS-ES Matrix 6.1 to achieve 6.1-
channel surround playback. DTS Neo : 6 surround includes two
modes for selecting the optimum decoding for the signal source.
• DTS Neo : 6 Cinema
This mode is optimum for playing movies. Decoding is
performed with emphasis on separation performance to
achieve the same atmosphere with 2-channel sources as with
6.1-channel sources.
• DTS Neo : 6 Music
This mode is suited mainly for playing music. The front left
and front right signals bypass the decoder and are played
directly so there is no loss of sound quality, and the effect of
the surround signals from the center, surround left, surround
right and surround back channels adds a natural sense of
expansion to the sound field.
■ DTS 96/24
Conventional surround formats used sampling frequencies of
48 or 44.1 kHz, so 20 kHz was about the maximum playback
signal frequency. With DTS 96/24, the sampling frequency is
increased to 96 or 88.2 kHz to achieve a wide frequency
range of over 40 kHz. In addition, this format has a resolution
of 24 bits, resulting in the same frequency band and dynamic
range as 96kHz / 24 bit PCM signals.
As with conventional DTS surround, DTS 96/24 is compatible
with a maximum of 5.1 channels. DTS 96/24 is fully
compatible with the conventional DTS surround format, so
DTS 96/24 sources can be played using a conventional DTS
5.1 channel decoder.

■ Dolby Digital
Dolby Digital is the multi- channel digital signal format
developed by Dolby Laboratories. Discs bearing the
“ ” includes the recording of up to 5.1 channels of
digital signals, which can reproduce much better sound
quality, spatial expansion and dynamic range characteristics
than the previous Dolby Surround effect.
■ Dolby Digital EX
This mode creates the back (sometimes also referred to as
“surround center”) signals from the surround left and right
signals in Dolby Digital 5.1 channel source using a matrix
decoder and provides 6.1 channel surround playback. For the
best results, this mode should be selected during playback of
sources(bearing the “ ”) recorded in Dolby Digital
EX. With this additional channel, you can experience more
dynamic and realistic moving sound especially.
When Dolby Digital EX sources are decoded with a Dolby
Digital EX decoder, the format is automatically detected upon
decoding and the Dolby Digital EX mode is selected.
However, some Dolby Digital EX sources may be detected as
Dolby Digital sources. In this case, the Dolby Digital EX mode
should be selected manually to play these sources.
