THX

The THX technologies are explained below.

See http://www.thx.com for more detailed

information.

THX Cinema

A mode for playing in a home theater environ-

ment the sound tracks of theater movies that

have been recorded and edited for playback in

large spaces such as movie theaters.

THX Music

A mode adjusted mainly for listening to music

that has been masterized at a higher level than

movie sound tracks.

THX Games

A mode for playing the sound of games with

spatial fidelity. In many cases the sound is

mixed in the same way as for movies, but this

mode is meant for small environments rather

than the large environments of theaters.

THX Surround EX

A mode using technology developed jointly

by Dolby Laboratories and THX for creating a

sound field behind the listeners.

THX Loudness Plus

A mode creating a rich, subtle surround sound

field through optimal calibration of the volume

and frequency response of the individual chan-

nels according to the volume level.

Decoding

A technology for converting digital signals

that have been compressed upon recording

by a digital signal processing circuit, etc., into

the original signals. The term “decoding” (or

“matrix decoding”) is also used for the technol-

ogy which converts 2-channel sound sources

into multiple channels or expands 5.1-channel

signals into 6.1 or 7.1 channels.

Calibrating the sound field/

Improving the sound quality

Phase Control

The Phase Control technology incorporated into

this receiver’s design provides coherent sound

reproduction through the use of phase match-

ing for an optimal sound image at your listening

position.

Full Band Phase Control

The Full Band Phase Control feature calibrates

the frequency-phase characteristics of the

speakers connected.

Full Band Phase Control FRONT ALIGN

Full Band Phase Control calibrates frequency

phase disturbances (group delay) for the full

speaker band (Full Band) (SYMMETRY), but

with this unit it is also possible to calibrate the

frequency phase characteristics of other speak-

ers to the frequency phase characteristics of

the front speakers (FRONT ALIGN).

Virtual Surround Back

When you’re not using surround back speakers,

selecting this mode allows you to hear a virtual

surround back channel through your surround

speakers. You can choose to listen to sources

with no surround back channel information.

Virtual Height

When you’re not using front height speak-

ers, selecting this mode allows you to hear a

virtual front height channel through your front

speakers.

Virtual Depth

When this mode is selected, the sound field

expands virtually to behind the display, result-

ing in a sound field with the same depth as

the 3D picture to achieve a better sense of

presence.

Auto Sound Retriever

The Auto Sound Retriever feature employs

DSP technology to restore sound pressure

Glossary

Audio formats/Decoding

Dolby

The Dolby technologies are explained below.

See http://www.dolby.com for more detailed

information.

Dolby Digital

Dolby Digital is a multichannel digital audio

coding system widely used in cinemas, and

in the home for DVD and digital broadcast

soundtracks.

Dolby TrueHD

Dolby TrueHD is the lossless encoding technol-

ogy developed for high-definition optical discs

in the upcoming era.

Dolby Digital Plus

Dolby Digital Plus is the audio technology for

all high-definition programming and media. It

combines the efficiency to meet future broad-

cast demands with the power and flexibility to

realize the full audio potential expected in the

upcoming high-definition era.

Dolby Digital Surround EX

Dolby Digital Surround EX (the EX stands for

EXtended) is an extension of Dolby Digital

encoding whereby a surround back channel

is matrixed into the surround left/right chan-

nels for 6.1 channel playback. This allows for

compatibility with Dolby Digital 5.1 channel

decoding, as well as for decoding using Dolby

Digital EX.

Dolby Pro Logic IIx and Dolby Surround

Dolby Pro Logic IIx is an improved version of the

Dolby Pro Logic II (and Dolby Pro Logic) decod-

ing system.

Dolby Surround is an encoding system which

embeds surround sound information within

a stereo soundtrack, which a Dolby Pro Logic

decoder can then use for enhanced surround

listening with greater sound detail.

Dolby Pro Logic IIz

Adding a pair of speakers above the front left

and right speakers adds expressiveness in the

vertical direction to the previous horizontally-

oriented sound field. The height channel

strengthens the sound field’s sense of three-

dimensionality and air, producing presence and

expansion.

DTS

The DTS technologies are explained below.

See http://www.dts.com for more detailed

information.

DTS Digital Surround

DTS Digital Surround is a 5.1-channel audio

coding system from DTS Inc. now widely used

for DVD-Video, DVD-Audio, 5.1 music discs,

digital broadcasts, and video games.

DTS-HD Master Audio

DTS-HD Master Audio is a technology that

delivers master audio sources recorded in a

professional studio to listeners without any loss

of data, preserving audio quality.

DTS-HD High Resolution Audio

A high definition audio technology by which

signals can be transferred over HDMI cables.

DTS-ES

DTS-ES (the ES stands for Extended Surround)

is a decoder that is capable of decoding both

DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1

encoded sources.

DTS Neo:X

DTS Neo:X can generate 11.1 channel surround

sound from any matrixed stereo source (such

as video or TV) and from 5.1 channel sources.

DTS Neural Surround

DTS Neural Surround can generate 7.1 chan-

nel surround sound from any matrixed stereo

source (such as video or TV).
