Auto Setup / Room EQ
The Auto Setup and Room EQ function of this
unit performs an analysis of the speaker system
and measures the acoustic characteristics of your
room to permit an appropriate automatic setting.
The AVR-3806’s Audyssey MultEQ XT function
has the feature that it provides the optimum
listening environment at all listening positions in
the home theater, where there are often
multiple listeners viewing programs together.
To achieve this, it is first necessary to use a
microphone to measure test tones generated
from the different speakers at the various
listening positions. All this measured data is
analyzed with a unique method to
comprehensively improve acoustic characteristics
in the listening area. For optimum effectiveness,
measurements should be performed at six
points. Move the microphone successively
within the listening area surrounded by the
speakers as shown on the diagram below to
measure the test tones. When listening to
music or viewing movies with the whole family,
move the microphone successively to the
different positions in which the members of the
family sit (“ ” on the diagram indicates the
points of installation) and measure repeatedly
(Example q). Even if the number of people
using the home theater is small, taking multiple
measurements at or near the listening positions
makes it possible to correct the sound more
effectively (Example w).
The AVR-3806’s Room EQ function offers three
correction curves: “Audyssey”, “Front” and
“Flat”. These can be selected after performing
the auto setup procedure. Details of the
different correction curves are described below.
• Audyssey:
This adjusts the frequency response of all
speakers to correct the effects of room
acoustics.
• Front:
This adjusts the characteristics of each
speaker to the characteristics of the front
speakers.
• Flat:
This the frequency response of all speakers flat.
This is suitable for multi-channel music
reproduction, from discrete music sources
such as Dolby Digital 5.1, DTS, DVD-Audio
and Super Audio CD.
2 About the main listening position
(*M)
The main listening position is the point where a
listener sits most often or the listening position
when only one person is listening.
Measurements on the AVR-3806 start from this
point. Correction for the speaker distance is set
based on this point.
