Dolby Digital

Dolby Digital is a multichannel 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.

Surround

Dolby Surround

The AVR-2309 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.

Dolby Pro Logic g

Dolby Pro Logic g 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.

Dolby Pro Logic gx

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

Logic g matrix decoding technology.

Audio signals recorded in 2-channels are decoded to achieve a natural

sound with up to 7.1-channels.

There are 3 modes: “Music” suited for playing music, “Cinema”

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

games.
