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-5805CI’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-5805CI’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:

Makes the frequency response for all the 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.

2About 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-5805CI start from this point. Correction for the speaker distance (“Delay Time”) is set based on this point.
