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

(CS-

) is a powerful and versatile

multichannel technology. CS-

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-

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-

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-

is packed with other useful feature like dialog

clarity (SRS Dialog) for movies and cinema-like bass
enrichment (TruBass). CS-

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.

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

surfaces and standing waves that are 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 every person in the room.
It is not uncommon to have variations in two adjacent
seats that are as large as 10 dB, particularly in the
frequency range below 250 Hz.
The solution to this problem is to apply room correction
after precisely measuring 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 measure each loudspeaker at 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 that can 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 that minimizes the acoustical effects of the
room and is matched to the frequency resolution of
human perception (known as psychoacoustics).
Furthermore, MultEQ correction is applied both
in frequency and time domains and so there are
no artifacts (such as smearing of sound or modal
ringing)that are 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 how many loudspeakers are connected to the
amplifi ers and whether they are full-range, 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 if there are any that may be 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 that sound from each loudspeaker
arrives at the same time. Finally, Audyssey MuitEQ
determines the playback level of each loudspeaker and
adjusts the volume trims so that all levels are equal.

HD Radio

technology is a new technology that

enables AM and FM radio stations to broadcast
programs digitally. Digital broadcasting provides
listeners with radically improved audio quality and
reception as well as new data services. Furthermore,
supplemental program services allow listeners to
select from up to 8 HD Radio programs multicast on
a single FM HD Radio channel. For more information
