The relation between the selected surround mode and the input signal
The surround mode is selected with the surround mode buttons on SR5002 or the remote control unit.However, the sound
you hear is subject to the relationship between the selected surround mode and input signal.That relationship is as follows;

•
Neo:6 technology allows various sound elements
within a channel or channels to be steered
separately, and in a way which follows naturally
from the original presentation.
• Neo:6 offers a music mode to expand stereo nonmatrix
recordings into the five- or six-channel layout, in a way
which does not diminish the subtlety and integrity of
the original stereo recording.
• dts Digital Surround ES
DTS-ES Extended Surround is a new multichannel
digital signal format developed by Digital Theater
Systems Inc.While offering high compatibility with the
conventional DTS Digital Surround format, DTS-ES
Extended Surround greatly improves the 360-degree
surround impression and space expression thanks
to further expanded surround signals. This format
has been used professionally in movie theaters since
1999.
In addition to the 5.1 surround channels (FL, FR, C,
SL, SR and LFE), DTS-ES Extended Surround also
offers the SB (Surround Back) 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 DTS-
ES Discrete 6.1 and DTS-ES Matrix 6.1.
• dts Digital Surround 96/24
The stereo CD is a 16-bit medium with sampling at
44.1 kHz. Professional audio has been 20- or 24-
bit for some time, and there is increasing interest
in higher sampling rates both for recording and for
delivery into the home. Greater bit depths provide
extended dynamic range. Higher sampling rates
allow wider frequency response and the use of anti-
alias and reconstruction filters with more favorable
aural characteristics.
DTS 96/24 allows for 5.1channel sound tracks to be
encoded at a rate of 96kHz/24bits on DVD-Video
titles.
When DVD-video appeared, it became possible to
deliver 24-bit, 96 kHz audio into the home, but only in
two channels, and with serious limitations on picture.
This capability has had little use.
DVD-audio allows 96/24 in six channels, but a
new player is needed, and only analog outputs are
provided, necessitating the use of the D/A converters
and analog electronics provided in the player.
DTS 96/24 offers the following:
1. Sound quality transparent to the original 96/24
master.

• dts Digital Surround
DTS was introduced in 1994 to provide 5.1 channels of
discrete digital audio into home theater systems.
DTS brings you premium quality discrete multichannel
digital sound to both movies and music.
DTS is a multichannel sound system designed to
create full range digital sound reproduction.
The no compromise DTS digital process sets the
standard of quality for cinema sound by delivering
an exact copy of the studio master recordings to
neighborhood and home theaters.
Now, every moviegoer can hear the sound exactly as
the moviemaker intended.
DTS can be enjoyed in the home for either movies or
music on of DVD’s, LD’s, and CD’s.
• dts Neo:6
The advantages of discrete multichannel systems
over matrix are well known.
But even in homes equipped for discrete multichannel,
there remains a need for high-quality matrix decoding.
This is because of the large library of matrix surround
motion pictures available on disc and on VHS tape; and
analog television broadcasts.
The typical matrix decoder of today derives a center
channel and a mono surround channel from two-
channel matrix stereo material. It is better than a
simple matrix in that it includes steering logic to
improve separation, but because of its mono, band-
limited surround it can be disappointing to users
accustomed to discrete multichannel.
Neo:6 offers several important improvements as
follow,
• Neo:6 provides up to six full-band channels of
matrix decoding from stereo matrix material. Users
with 6.1 and 5.1 systems will derive six and five
separate channels, respectively, corresponding to
the standard home-theater speaker layouts.

Dolby Pro Logic IIx is fully compatible with Dolby
Surround Pro Logic technology and can optimally
decode the thousands of commercially available
Dolby Surround encoded video cassettes and
television programs with enhanced depth and
spatiality. It can also process any high-quality
stereo or Advanced Resolution 5.1-channel music
content into a seamless 6.1- or 7.1-channel listening
experience.
The Dolby Headphone technology provides a
surround sound listening experience over headphones.
When listening to multichannel content such as DVD
movies over headphones, the listening experience
is fundamentally different than listening to speakers.
Since the headphone speaker drivers are covering
the pinna of the ear, the listening experience differs
greatly from traditional speaker playback. Dolby
utilizes patented headphone perspective curves to
solve this problem and provides a non-fatiguing,
immersive, home theater listening experience. Dolby
Headphone also delivers exceptional 3D audio from
stereo material.
Manufactured under license from Dolby Laboratories.

Circle Surround II (CS-II) is a powerful and versatile
multichannel technology. CS-II is designed to enable
up to 6.1 multichannel surround sound playback
from mono, stereo, CS encoded sources and other
matrix encoded sources. In all cases the decoder
extends it into 6 channels of surround audio and a
LFE/subwoofer signal. The CS-II decoder creates a
listening environment that places the listener “inside”
music performances and dramatically improves
both hi-fi audio conventional surround-encoded
video material. CS-II provides composite stereo rear
channels to greatly improve separation and image
positioning – adding a heightened sense of realism
to both audio and A/V productions.
2.
Full backward compatibility with all existing
decoders. (Existing decoders will output a 48 kHz
signal)
3. No new player required: DTS 96/24 can be carried
on DVD-video, or in the video zone of DVD-audio,
accessible to all DVD players.
4. 96/24 5.1-channel sound with full-quality full-
motion video, for music programs and motion
picture soundtracks on DVD-video.
Dolby Digital identifies the use of Dolby Digital audio
coding for such consumer formats as DVD and DTV.
As with film sound, Dolby Digital can provide up
to five full-range channels for left, center, and right
screen channels, independent left and right surround
channels, and a sixth (“.1”) channel for low-frequency
effects.
Dolby Surround Pro Logic II is an improved matrix
decoding technology that provides better spatiality
and directionality on Dolby Surround program
material; provides a convincing three-dimensional
soundfield on conventional stereo music recordings;
and is ideally suited to bring the surround experience
to automotive sound. While conventional surround
programming is fully compatible with Dolby Surround
Pro Logic II decoders, soundtracks will be able to be
encoded specifically to take full advantage of Pro
Logic II playback, including separate left and right
surround channels. (Such material is also compatible
with conventional Pro Logic decoders.)
Dolby Digital EX creates six full-bandwidth output
channels from 5.1-channel sources. This is done
using a matrix decoder that derives three surround
channels from the two in the original recording. For
best results, Dolby Digital EX should be used with
movies soundtracks recorded with Dolby Digital
Surround EX.
About Dolby Pro Logic II x
Dolby Pro Logic IIx technology delivers a natural
and immersing 7.1-channel listening experience
to the home theater environment. A product of
Dolby’s expertise in surround sound and matrix
decoding technologies, Dolby Pro Logic IIx is a
complete surround sound solution that maximizes
the entertainment experience from stereo as well as
5.1-channel encoded sources.

CS-II is packed with other useful feature like dialog
clarity (SRS Dialog) for movies and cinema-like bass
enrichment (TruBass). CS-II can enable the dialog
to become clearer and more discernable in movies
and it enables the bass frequencies contained in
the original programming to more closely achieve
low frequencies – overcoming the low frequency
limitations of the speakers by full octave.

HDCD®(High Definition Compatible Digital ®) is a
patented process for delivering on Compact Disc the
full richness and details of the original microphone
feed.
HDCD encoded CDs sound better because they are
encoded with 20-bits of real musical information as
compared to 16-bits for all other CDs.
HDCD overcomes the limitation of the 16-bit CD
format by using a sophisticated system to encode
the additional four bits onto the CD while remaining
completely compatible with the CD format.
When listening to HDCD recordings, you hear more
dynamic range, a focused 3-D sound stage, and
extremely natural vocal and musical timbre. With
HDCD, you get the body, depth and emotion of the
original performance not a flat, digital imitation.
