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
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 IIx
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.
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.

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.
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
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.
