Audio information

■ Audio decoding format

Dolby Atmos (RX-A850 only)

Introduced first in the cinema, Dolby Atmos brings a revolutionary sense of dimension and immersion to the

Home Theater experience. Dolby Atmos is an adaptable and scalable object based format that reproduces

audio as independent sounds (or objects) that can be accurately positioned and move dynamically

throughout the 3 dimensional listening space during playback. A key ingredient of Dolby Atmos is the

introduction of a height plane of sound above the listener.

Dolby Atmos Stream (RX-A850 only)

Dolby Atmos content will be delivered to your Dolby Atmos enabled AV receiver via Dolby Digital Plus or

Dolby TrueHD on Blu-ray Disc, downloadable files and streaming media. A Dolby Atmos stream contains

special metadata that describes the positioning of sounds within the room. This object audio data is

decoded by a Dolby Atmos AV receiver and scaled for optimum playback through Home Theater speaker

systems of every size and configuration.

Dolby Digital

Dolby Digital is a compressed digital audio format developed by Dolby Laboratories, Inc. that supports

5.1-channel audio. This technology is used for audio on most DVD discs.

Dolby Digital EX

Dolby Digital EX creates total 6.1-channel audio from 5.1-channel sources that are recorded with Dolby

Digital Surround EX. This decoder adds a surround back sound to the original 5.1-channel sound.

Dolby Digital Plus

Dolby Digital Plus is a compressed digital audio format developed by Dolby Laboratories, Inc. that supports

7.1-channel audio. Dolby Digital Plus remains fully compatible with the existing multichannel audio systems

that support Dolby Digital. This technology is used for audio on BD (Blu-ray discs).

Dolby Enabled Speaker (RX-A850 only)

A convenient alternative to speakers built into the ceiling, products utilizing Dolby speaker technology

employ the ceiling above you as a reflective surface for reproducing audio in the height plane above the

listener. Dolby enabled speakers feature a unique upward firing driver and special signal processing that

can be built into a conventional speaker, or a standalone speaker module, minimally impacting the overall

speaker system footprint while providing an immersive listening experience during Dolby Atmos and Dolby

surround playback.

Dolby Pro Logic II

Dolby Pro Logic II enables 5-channel playback from 2-channel sources. There are three modes available:

“Music mode” for music sources, “Movie mode” for movie sources, and “Game mode” for game sources.

Dolby Pro Logic IIx

Dolby Pro Logic IIx enables 7-channel playback from 2-channel or multichannel sources. There are three

modes available: “Music mode” for music sources, “Movie mode” for movie sources and “Game mode” for

game sources (for 2-channel sources only).

Dolby Surround (RX-A850 only)

Dolby surround is a next generation surround technology that intelligently up mixes stereo; 5.1 and 7.1

content for playback through your surround speaker system. Dolby surround is compatible with traditional

speaker layouts, as well as Dolby Atmos enabled playback systems that employ in-ceiling speakers or

products with Dolby speaker technology.

Dolby TrueHD

Dolby TrueHD is an advanced lossless audio format developed by Dolby Laboratories, Inc. to offer a

high-definition home theater experience with the quality of the studio master. Dolby TrueHD can carry up to

eight channels of 96 kHz/24-bit audio (up to six channels of 192 kHz/24-bit audio) simultaneously. This

technology is used for audio on BD (Blu-ray discs).

DSD (Direct Stream Digital)

DSD (Direct Stream Digital) technology stores audio signals on digital storage media, such as SACD (Super

Audio CDs). The signals are stored at a high-frequency sampling rate (such as 2.8224 MHz and 5.6448

MHz). The highest frequency response is equal to or higher than 100 kHz, with a dynamic range of 120 dB.

This technology offers better audio quality than that used for CDs.

DTS 96/24

DTS 96/24 is a compressed digital audio format that supports 5.1-channel and 96 kHz/24-bit audio. This

format remains fully compatible with the existing multichannel audio systems that support DTS Digital

Surround. This technology is used for music DVDs, etc.

DTS Digital Surround

DTS Digital Surround is a compressed digital audio format developed by DTS, Inc. that supports

5.1-channel audio. This technology is used for audio on most DVD discs.

DTS-ES

DTS-ES creates total 6.1-channel audio from 5.1-channel sources that are recorded with DTS-ES. This

decoder adds a surround back sound to the original 5.1-channel sound. In the DTS-ES Matrix 6.1 format, a

surround back sound is recorded in the surround channels, and in the DTS-ES Discrete 6.1 format, a

discrete surround back channel is recorded.

DTS Express

DTS Express is a compressed digital audio format that supports 5.1-channel audio and allows a higher

compression rate than the DTS Digital Surround format developed by DTS, Inc. This technology is

developed for audio streaming services on the Internet and secondary audio on BD (Blu-ray discs).

DTS-HD High Resolution Audio is a compressed digital audio format developed by DTS, Inc. that supports

7.1-channel and 96 kHz/24-bit audio. DTS-HD High Resolution Audio remains fully compatible with the

existing multichannel audio systems that support DTS Digital Surround. This technology is used for audio on

BD (Blu-ray discs).
