Other Information

The AVR-890 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 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.

Dolby Digital Plus

Dolby Digital Plus is an improved Dolby Digital signal format that is

compatible with up to 7.1-channels of discrete digital sound and also

improves sound quality thanks to extra data bit rate performance. It

is upwardly compatible with conventional Dolby Digital, so it offers

greater ﬂexibility in response to the source signal and the conditions

of the playback equipment.

Dolby TrueHD

Dolby TrueHD is a high deﬁnition audio technology developed by Dolby

Laboratories, using lossless coding technology to faithfully reproduce

the sound of the studio master.

This format is compatible with a maximum sampling frequency of 96

kHz and up to 7.1-channels, so it is used for applications particularly

prioritizing sound quality.

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.

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.

Manufactured under license from Dolby Laboratories.

“Dolby”, “Pro Logic” and the double-D symbol are trademarks of

Dolby Laboratories.

Dolby Digital EX

Dolby Digital EX is a 6.1-channel surround format proposed by Dolby

Laboratories that allows users to enjoy in their homes the “DOLBY

DIGITAL SURROUND EX” audio format jointly developed by Dolby

Laboratories and Lucas Films.

The 6.1 channels of sound, including surround back channels, provide

improved sound positioning and expression of space.

Dolby Pro Logic gz

Dolby Pro Logic gz introduces a new dimension to Home Entertainment

through the addition of a pair of front height channels. Compatible with

stereo, 5.1 and 7.1 content, Dolby Pro Logic gz provides enhanced

spaciousness, depth and dimension to movies, concert video and

videogame playback while maintaining the full integrity of the source

mix.

Dolby Pro Logic gz identiﬁes and decodes spatial cues that occur

naturally in all content, directing this information to the front height

channels, complementing the performance of left and right surround

sound speakers. Content that is encoded with Dolby Pro Logic

gz height channel information can be even more revealing, with

perceptually discrete height channel information bringing an exciting

new dimension to home entertainment. Dolby Pro Logic gz, with

front height channels is also an ideal alternative for households that

cannot support the placement of back surround speakers of a typical

7.1 channel system but may have bookshelf space available to support

the addition of height speakers.
