Easy Setup and Operation
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-4806CI’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 or
more 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-4806CI’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.

¢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-4806CI
start from this point. Correction for the speaker distance
(“Delay Time”) is set based on this point.
