Dolby Digital identifi es the use of Dolby Digital audio
coding for such consumer formats as DVD and DTV.
As with fi lm sound, Dolby Digital can provide up
to fi ve 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
soundfi eld 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 specifi cally 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 IIx
Dolby Pro Logic II x 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 II x is a
complete surround sound solution that maximizes
the entertainment experience from stereo as well as
5.1-channel encoded sources.
Dolby Pro Logic II x 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.
Dolby Virtual Speaker is a technologycertified
by Dolby Laboratories that creates a virtualized
surround sound experience from two speakers using
a multichannel Dolby Digital source. Additionally,
Dolby Virtual Speaker can simulate the surround
sound effect produced by Dolby Pro Logic or Dolby
Pro Logic I I .
Dolby Virtual Speaker retains all the original
Multichannel audio information and provides the
listener with the sensation of being surrounded by
additional speakers.

TrueHD is Dolby’s next-generation lossless
technology developed for high-defi nition disc-based
media. Dolby TrueHD delivers tantalizing sound
that is bit-for-bit identical to the studio master,
unlocking the true high-definition entertainment
experience on next-generation discs. When coupled
with high-defi nition video, Dolby TrueHD offers an
unprecedented home theater experience that lets
you enjoy sound as stunning as the high-defi nition
picture.
Dolby Digital Plus is a highly sophisticated and
versatile audio codec based on Dolby Digital and
designed specifically to adapt to the changing
demands of future audio, video delivery, and audio
storage systems while simultaneously retaining
backwards compatibility with the existing Dolby
Digital 5.1-channel home theater systems in use
today.
Manufactured under license from Dolby Laboratories.

Circle Surround II (CS-II) is a powerful and versatile
multichannel technology. CS-I I 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.
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 Defi nition 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 fl at, digital imitation.

Several factors can degrade the sound from even
the best loudspeakers in a listening room. One
of the most important is the interaction of sound
from the loudspeakers with large surfaces such as
walls, the fl oor and the ceiling in the room. Even
with careful loudspeaker placement and acoustical
treatments, there are signifi cant problems that are
caused by room acoustics. These include refl ections
from nearby surfaces and standing waves created
between large parallel surfaces in the room. In a
home theater, the situation is further complicated
because there are several listening locations. The
effects of room acoustics on the sound arriving at
each person’s ears are very different and the result is
a listening experience that is degraded in a different
way for each person in the room.
It is not uncommon to have variations in two adjacent
seats as large as 10 dB, particularly in the frequency
range below 250 Hz. The solution to this problem is to
apply room correction after measuring precisely how
each loudspeaker interacts with the room. Because
the room causes variations in the frequency response
of the loudspeakers that are so large from seat to
seat, it is important to sample the sound from several
locations in the listening room. This should be done
even if there is only one listener. Measurement at a
single location is not representative of the acoustical
problems in the room and will, in most cases,
degrade overall performance. Audyssey MultEQ is
the only technology able to achieve room correction
for multiple listeners in a large listening area. It does
so by combining the data collected at several points
in the room from each loudspeaker and then applying
correction to minimize the acoustical effects of the
room and match the frequency resolution of human
perception (known as psychoacoustics).
Further, MultEQ correction is applied in frequency
and time domains and removes artifacts, such as
smearing or modal ringing, sometimes associated
with traditional methods of room equalization.
In addition to correcting frequency response problems
over a wide listening area, Audyssey MultEQ provides
a completely automated sound system set-up
process. It identifi es the number of loudspeakers
connected to the amplifi ers and whether they are
satellites or subwoofers. If there is a least one
subwoofer connected, Audyssey MultEQ determines
the optimum crossover frequency between each
satellite and the subwoofer(s). It automatically
checks the polarity of each loudspeaker and alerts
the user to the ones wired out-of- phase relative to
the others.
It measures the distance to each loudspeaker from
the main listening position and adjusts the delays
so the sound from each loudspeaker arrives at the
same time. Finally, Audyssey MultEQ determines the
playback level of each loudspeaker and adjusts the
volume trims so all levels are equal.
