Dolby Virtual Speaker retains all the original
Multichannel audio information and provides the
listener with the sensation of being surrounded by
additional speakers.
Dolby 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-defi nition 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.

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
AV8003̲U̲Eng.indb 103
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.

There are several factors that 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 significant problems that are caused by
room acoustics. These include refl ections from nearby
