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 (

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” (

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.

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. 

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. 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.

• 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.

Test tones are played through each speaker as 
Audyssey 2EQ Room Correction and Speaker Setup 
runs. This process takes a few minutes. Please 
refrain from talking during measurements and do 
not stand between speakers and the microphone.
Do not disconnect the speaker setup microphone
