En
With the supplied calibrated microphone, Audyssey 2EQ
automatically determines the number of speakers con-
nected, their size for purposes of bass management, opti-
mum 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 every-
one. Enabling Audyssey 2EQ allows you to also use
Audyssey Dynamic EQ
™ , which maintains the proper
octave-to-octave balance at any volume level ( ➔ 38).
Before using this function, connect and position all of
your speakers.
If “Dynamic EQ” is set to “On” (
➔ 39), the “Audyssey”
setting will be set to “Off” (
➔
38). On the other hand, if it
is set to “Off”, the “Dynamic Volume” setting will be set
to “Off” (
➔ 39).
It takes about 15 minutes to complete Audyssey 2EQ
Room Correction and Speaker Setup for three positions.
Total measurement time varies depending on the number
of speakers.
Using Audyssey 2EQ
To create a listening environment in your home theater
that all listeners will enjoy, Audyssey 2EQ takes measure-
ments 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. 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.
Note
• Make the room as quiet as possible. Background noise and Radio
Frequency Interference (RFI) can disrupt the room measure-
ments. Close windows, televisions, radios, air conditioners, flu-
orescent 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 which played through each
speaker as Audyssey 2EQ Room Correction and Speaker Setup
run.
• Audyssey 2EQ Room Correction and Speaker Setup cannot be
performed while a pair of headphones is connected.
