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 ® ( ➔ page 56 ).
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.
The more positions are used in measuring, the better the
listening environment will become. We recommend using
a measurement from three positions to create the best
listening environment.
The Quick Start takes 2 minutes and Full Calibration takes
about 10 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 2EQ takes measurements
at up to three 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 2EQ uses the measurements from this
position to calculate speaker distance, level, polarity,
and the optimum crossover value for the subwoofer.
Second measurement position
The right side of the listening area.
Third measurement position
The left side of the listening area.
The distances from position to and to must be
at least 1 meter (3.3 ft.).
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 2EQ Room Correction and Speaker Setup runs.
• Audyssey 2EQ Room Correction and Speaker Setup cannot be
performed while a pair of headphones is connected.
