First Time Setup
—Continued
With the supplied calibrated microphone,
Audyssey MultEQ automatically determines the number
of speakers connected, their size for purposes of bass
management, optimum crossover frequencies to the
subwoofer (if present), and distances from the primary
listening position.
Audyssey MultEQ then removes the distortion caused
by room acoustics by capturing room acoustical
problems over the listening area in both the frequency
and time domain. The result is clear, well-balanced
sound for everyone. Enabling Audyssey MultEQ allows
you to also use Audyssey Dynamic EQ™, which
maintains the proper octave-to-octave balance at any
volume level (see page 91).
Before using this function, connect and position all of
your speakers.
Measurement Positions
To create a listening environment in your home theater
that all listeners will enjoy, Audyssey MultEQ takes
measurements at up to six positions within the listening
area.
■ First measurement point
Also referred to as the Main Listening Position this
refers to the most central position where one would
normally sit within the listening environment.
MultEQ uses the measurements from this position to
calculate speaker distance, level, polarity, and the
optimum crossover value for the subwoofer.
■ Second
−
Sixth measurement positions
These are the other listening positions (i.e., the
places where the other listeners will sit). You can
measure up to six positions.
The following examples show some typical home theater
seating arrangements. Choose the one that best matches
yours, and position the microphone accordingly when
prompted.

About Audyssey Dynamic EQ
Audyssey Dynamic EQ solves the problem of deterio-
rating 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 user-
selected 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 prereq-
uisite 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.
About Audyssey 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 pre-
ferred volume setting by the user and then monitors
how the volume of program material is being per-
ceived by listeners in real time to decide whether an
adjustment is needed. Whenever necessary, Dynamic
Volume makes the necessary rapid or gradual adjust-
ments to maintain the desired playback volume level
while optimizing the dynamic range.
Audyssey Dynamic EQ is integrated into Dynamic
Volume so that as the playback volume is adjusted
automatically, the perceived bass response, tonal bal-
ance, surround impression, and dialog clarity remain
the same whether watching movies, flipping between
television channels, or changing from stereo to sur-
round sound content.
