First Time Setup—Continued
With the supplied calibrated microphone,
Audyssey 2EQ 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 2EQ 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 2EQ allows you to also
use Audyssey Dynamic EQ
™
, which maintains the
proper octave-to-octave balance at any volume level (see
page 74).
Before using this function, connect and position all of
your speakers.
If Audyssey Dynamic EQ is set to “On”,
Audyssey Dynamic Volume
™
becomes available.
Measurement Positions
To create a listening environment in your home theater
that all listeners will enjoy, Audyssey 2EQ takes
measurements at up to three positions within the
listening area.
a 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. 2EQ
uses the measurements from this position to calcu-
late speaker distance, level, polarity, and the opti-
mum crossover value for the subwoofer.
b Second measurement point
The right side of the listening area.
c Third measurement point
The left side of the listening area.
The distances between points
a and b and points a
and c must be at least 1 meter.
From the examples below, choose the listening area that
best matches yours and place the microphone
accordingly when prompted.

About Audyssey Dynamic EQ
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 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
prerequisite for delivering a loudness correction
solution. Audyssey Dynamic EQ works in tandem
with Audyssey 2EQ 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
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 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
balance, surround impression, and dialog clarity
remain the same whether watching movies, flipping
between television channels, or changing from stereo
to surround sound content.
