Additional Information Additional Information

The AVR-3806 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 Surround

q Dolby Digital

Dolby Digital is the multi-channel digital signal format

developed by Dolby Laboratories.

Dolby Digital consists of up to “5.1” channels - front left,

front right, center, surround left, surround right, and an

additional channel exclusively reserved for additional deep

bass sound effects (the Low Frequency Effects – LFE –

channel, also called the “.1” channel, containing bass

frequencies of up to 120 Hz).

Unlike the analog Dolby Pro Logic format, Dolby Digital’s

main channels can all contain full range sound information,

from the lowest bass, up to the highest frequencies – 22

kHz. The signals within each channel are distinct from the

others, allowing pinpoint sound imaging, and Dolby Digital

offers tremendous dynamic range from the most powerful

sound effects to the quietest, softest sounds, free from

noise and distortion.

1: Some DVD digital outputs have the function of switching

the Dolby Digital signal output method between “bit

stream” and “(convert to) PCM”. When playing in Dolby

Digital surround on the AVR-3806, switch the DVD

player’s output mode to “bit stream”. In some cases

players are equipped with both “bit stream + PCM” and

“PCM only” digital outputs. In this case connect the “bit

stream + PCM” terminals to the AVR-3806.

w Dolby Pro LogicII

• Dolby Pro LogicII is a new multi-channel playback format

developed by Dolby Laboratories using feedback logic

steering technology and offering improvements over

conventional Dolby Pro Logic circuits.

• Dolby Pro LogicII can be used to decode not only sources

recorded in Dolby Surround ( ) but also regular stereo

sources into five channels (front left, front right, center,

surround left and surround right) to achieve surround sound.

• Whereas with conventional Dolby Pro Logic the surround

channel playback frequency band was limited, Dolby Pro

LogicII offers a wider band range (20 Hz to 20 kHz or greater).

In addition, the surround channels were monaural (the

surround left and right channels were the same) with

previous Dolby Pro Logic, but Dolby Pro LogicII they are

played as stereo signals.

• Various parameters can be set according to the type of

source and the contents, so it is possible to achieve optimum

decoding ( page 36).

Sources recorded in Dolby Surround

• These are sources in which three or more channels of

surround have been recorded as two channels of signals

using Dolby Surround encoding technology.

• Dolby Surround is used for the sound tracks of movies

recorded on DVDs, LDs and video cassettes to be played

on stereo VCRs, as well as for the stereo broadcast

signals of FM radio, TV, satellite broadcasts and cable TV.

• Decoding these signals with Dolby Pro Logic makes it

possible to achieve multi-channel surround playback. The

signals can also be played on ordinary stereo equipment,

in which case they provide normal stereo sound.

• There are two types of DVD Dolby Surround recording

signals.

e Dolby Pro LogicIIx

• Dolby Pro LogicIIx furthers the matrix decoding technology

of Dolby Pro LogicII to decode audio signals recorded on two

channels into up to 7.1 playback channels, including the

surround back channel. Dolby Pro LogicIIx also allows 5.1-

channel sources to be played in up to 7.1 channels.

The mode can be selected according to the source. The

Music mode is best suited for playing music, the Cinema

mode for playing movies, and the Game mode for playing

games. The Game mode can only be used with 2-channel

audio sources.
