First Time Setup
This section explains the settings that you need to make before using the AV receiver for the very first time.
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 58)
Before using this function, connect and position all of
your speakers.
If Audyssey Dynanic EQ is set to “On”,
Audyssey Dynamic Volume
™ becomes available.
Measurement Positions
To create a listening environment in which several
people can enjoy your home theater simultaneously,
Audyssey 2EQ takes measurements at three 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. 2EQ
uses the measurements from this position to
calculate speaker distance, level, polarity, and the
optimum crossover value for the subwoofer.
Second measurement point
The right side of the listening area.
Third measurement point
The left side of the listening area.
The distances between points and and points
and 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.
Audyssey 2EQ™ Room Correction
and Speaker Setup
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.
