Surround speaker

• Set the front speakers with their front surfaces as flush

with the TV or monitor screen as possible. Set the center

speaker between the front left and right speakers and no

further from the listening position than the front speakers.

• Consult the operating instructions for your subwoofer for

advice on placing the subwoofer within the listening room.

• If the surround speakers are direct-radiating (monopolar)

then place them slightly behind and at an angle to the

listening position and parallel to the walls at a position 2 to

3 feet (60 to 90 centimeters) above ear level at the prime

listening position.

• Connect the surround speakers to the surround speaker A

terminals on the AVR-5805CI and set settings on the setup

menu to “A”. (This is the factory default setting ( page

153))

• The surround speakers can be switched freely during

playback with the surround parameter adjustment (

page 45).

Dolby Surround

The AVR-5805CI is equipped with a digital signal processing

circuit that lets you play program sources in the surround

mode to achieve the same sense of presence as in a movie

theater.

[1] Dolby Digital

Dolby Digital is the multi-channel digital signal format

developed by Dolby Laboratories.

A total of 5.1 channels are played: 3 front channels (“FL”,

“FR” and “C”), 2 surround channels (“SL” and “SR”) and the

“LFE” channel for low frequencies.

Because of this, there is no crosstalk between channels and a

realistic sound field with a “three-dimensional” feeling (sense

of distance, movement and positioning) is achieved.

A real, overpowering sense of presence is achieved when

playing movie sources in AV rooms as well.

[2] Dolby Pro Logic II

Dolby Pro Logic II is a matrix decoding technology developed

by Dolby Laboratories. Regular music such as that on CDs is

encoded into 5 channels to achieve an excellent surround

effect.

The surround channel signals are converted into stereo and

full band signals (with a frequency response of 20 Hz to 20

kHz or greater) to create a “three-dimensional” sound image

offering a rich sense of presence for all stereo sources.

[3] Dolby Pro Logic IIx

Dolby Pro Logic IIx is a further improved version of the Dolby

Pro Logic

II matrix decoding technology.

Audio signals recorded in 2 channels are decoded to achieve a

natural sound with up to 7.1 channels.

There are three modes: “Music” suited for playing music,

“Cinema” suited for playing movies, and “Game” which is

optimum for playing games.

[4] Dolby Headphone

This is a three-dimensional sound technology developed jointly

by Dolby Laboratories and Lake Technology Ltd. of Australia

for achieving surround sound using regular headphones.

Previously, when using headphones all the sounds resonated

inside the head and it was uncomfortable to listen with

headphones for long periods of time. Dolby Headphone

simulates speaker playback in a room and places the sound at

the front or the sides, outside the head, to achieve a powerful

sound like the sound of movie or home theaters. This

technology is mainly for multichannel audio/video equipment

with Dolby Digital or Dolby Pro Logic Surround decoding

functions and works with a high performance digital signal

processing (DSP) chip.

Dolby Headphone is effective not only for multichannel

sources but also for stereo programs.

On the AVR-5805CI, it is possible to output signals encoded in

the Dolby Headphone mode from the recording output

terminal and record them on a separate recorder.
