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-4306’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-4306’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-4306 start from this point. Correction
for the speaker distance is set based on this point.
