Using Basic Functions
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. Audyssey 2EQ can be used with
Audyssey Dynamic EQ
®
and
Audyssey Dynamic Volume
®
(
Before using this function, connect and position all of
your speakers.
Audyssey 2EQ offers two ways of measuring: the
“
Audyssey Quick Start
” and “
Audyssey 2EQ Full
Calibration
”.
• “
Audyssey Quick Start
” uses the measurement from
one position to perform the speaker setting only.
• “
Audyssey 2EQ Full Calibration
” uses the
measurement from three positions to correct room
response in addition to the speaker setting.
Each way of measurement take 2 and 10 minutes,
respectively.
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 2EQ takes
measurements at up to 3 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.
a
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 2EQ uses the measurements from this
position to calculate speaker distance, level, polarity,
and the optimum crossover value for the subwoofer.
b
Second measurement position
The right side of the listening area.
c
Third measurement position
The left side of the listening area.
The distances from position
a
to
b
and
a
to
c
must be
at least 1 meter.
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. Silence 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 2EQ Room Correction and Speaker Setup runs.
• Audyssey 2EQ Room Correction and Speaker Setup cannot be
performed while a pair of headphones is connected.
