DTS-ES
The DTS-ES (Digital Theater System-Extended Surround) represents
6.1-channel Discrete Surround format, expanding upon 5.1 surround.
DTS-ES format is a 6.1 channel sound system for movie theaters that
includes an additional surround center channel matrixed within sur-
round left and surround right. It’s compatible on predecessor DTS 5.1
system. The extra channel allows more accurate placement and
steering of sound across the rear soundstage. The DTS-ES receiver
will be required, to experience a discrete 6.1-channel mix.
The DTS-ES decoders used in home cinema systems have decoding
options for utilizing the extra channel, in addition to processing
existing 5.1 channel surround sound :
DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1 add the surround back
channel audio to the DTS 5.1-channel format to improve the acoustic
positioning and makes acoustic image movement more natural with
the 6.1-channel reproduction.

DSP mode
The DSP mode lets you add the atmosphere of a live concert or hall
to almost any type of program source. These modes are particularly
effective when used with stereo program sources, like CD, television,
and FM radio. You might enjoy trying the ARENA, JAZZ CLUB,
THEATER, STADIUM or DISCO mode the next time you watch a
concert or sporting event!
What's DSP?
DSP stands for Digital Signal Processor.
The way a sound is heard in an actual environment depends on a
variety of different factors. One of the most important is reverberation
(the act of decaying elements of sound echoing in various places).
The DSP modes produce the feeling of presence by using the DSP
to create reverberation, without spoiling the sound quality of the
original signal.
LFE = Low Frequency Effects. This channel delivers separate non-
directional bass signals to the subwoofer for more dynamic deep bass
sound effects.
When there is a LFE channel input in the DOLBY DIGITAL or DTS
format, the "
LFE
" indicator lights on the display of the receiver.
NEO:6
NEO:6 is a new technology which decodes 2-channel signals into 6-
channel signals using high-accuracy digital matrix technology. For the
best results, DTS-ES should be used with movie sound tracks re-
corded with DTS-ES format which contain a digital flag that will
automatically activate this feature. However, for some titles, this
feature has to be activated manually.
According to the signals to be played back, DTS NEO:6 uses either the
NEO:CINEMA mode optimized for movie playback or the NEO:MUSIC
mode optimized for music playback.

DTS
The DTS employs a larger amount of data than Dolby Digital to play
surround sound with higher quality. The DTS can be used with DVD
and LaserDisc software carrying the
mark. Although the number
of channels is 5.1 and identical to Dolby Digital, the DTS format
features lower audio compression rate in digital recording, which
enables audio with more profoundness and higher S/N. The wider
dynamic range and better channel separation also contribute to make
the surround sound more precise and larger in scale.
