Using Basic Functions
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. Audyssey MultEQ XT can be used with
Audyssey Dynamic EQ
® and
Audyssey Dynamic Volume ® (

page 53).
Before using this function, connect and position all of
your speakers.
Audyssey MultEQ XT offers two ways of measuring: the
“Audyssey Quick Start” and “Audyssey MultEQ XT
Full Calibration”.
• “Audyssey Quick Start” uses the measurement from
one position to perform the speaker setting only.
• “Audyssey MultEQ XT Full Calibration” uses the
measurement from eight positions to correct room
response in addition to the speaker setting.
The more positions are used in measuring, the better the
listening environment will become. We recommend using
a measurement from eight positions to create the best
listening environment.
The Quick Start takes 2 minutes and Full Calibration takes
about 20 minutes.
Total measurement time varies depending on the number
of speakers.
Measurement procedure
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. Position the microphone at ear height of a seated
listener with the microphone tip pointed directly at the
ceiling using a tripod. Do not hold the microphone in your
hand during measurements as this will produce inaccurate
results.
■
First measurement position
Also referred to as the Main Listening Position this
refers to the most central position where one would
normally sit within the listening environment.
Audyssey MultEQ XT uses the measurements from this
position 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.
Note
• Make the room as quiet as possible. Background noise and Radio
Frequency Interference (RFI) can disrupt the room
measurements. Close windows, televisions, radios, air
conditioners, fluorescent lights, home appliances, light dimmers,
or other devices. Turn off the cell phone (even if it is not in use)
or place it away from all audio electronics.
• The microphone picks up test tones played through each speaker
as Audyssey MultEQ XT Room Correction and Speaker Setup
run.
• Audyssey MultEQ XT Room Correction and Speaker Setup
cannot be performed while a pair of headphones is connected.
