HDCD (High Definition Compatible Digital
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.

MultEQ ®
Audyssey MultEQ is a room equalization solution
that calibrates any audio system so that it can
achieve optimum performance for every listener in
a large listening area. MultEQ captures acoustical
information at multiple locations throughout a
listening area in both the time and frequency
domains. It uses a sophisticated clustering algorithm
to combine this information so that acoustical
problems are accurately analyzed. Based on these
measurements, MultEQ calculates an equalization
solution that corrects for both time and frequency
response problems in the listening area and also
performs a fully automated surround system setup.
The result is clear, well-balanced sound for every
listener.
Dynamic EQ TM
Audyssey Dynamic EQ solves the problem of
deteriorating sound quality as volume is decreased
by taking into account human perception and
room acoustics. Dynamic EQ selects the correct
frequency response and surround levels moment-
by-moment at any userselected volume setting. The
result is bass response, tonal balance and surround
impression that remain constant despite changes
in volume. Dynamic EQ combines information from
incoming source levels with actual output sound
levels in the room, a prerequisite for delivering a
loudness correction solution. Audyssey Dynamic
EQ works in tandem with Audyssey MultEQ to
provide well-balanced sound for every listener at
any volume level.

Dynamic Volume
Audyssey Dynamic Volume solves the problem of
large variations in volume level between television
programs, commercials, and between the soft and
loud passages of movies.
Dynamic Volume looks at the preferred volume
setting by the user and then monitors how the
volume of program material is being perceived by
listeners in real time to decide whether an adjustment
is needed. Whenever necessary, Dynamic Volume
makes the necessary rapid or gradual adjustments
to maintain the desired playback volume level while
