With the supplied calibrated microphone, 
Audyssey MultEQ XT 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 XT 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 XT 
allows you to also use Audyssey Dynamic EQ
, which 
maintains the proper octave-to-octave balance at any 
volume level (see page 102).
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 MultEQ XT takes 
measurements at up to eight 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 XT uses the measurements from this posi-
tion to calculate speaker distance, level, polarity, and 
the optimum crossover value for the subwoofer.
■ Second
eighth measurement positions
These are the other listening positions (i.e., the 
places where the other listeners will sit). You can 
measure up to eight 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 XT 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.
