2. TECHNICAL DESCRIPTION

THX® is an exclusive set of standards and

technologies established by the world-renowned

film production company, Lucasfilm Ltd. THX

resulted from George Lucas’ desire to reproduce

the movie soundtrack as faithfully as possible both

in the movie theater and in the home theater.

THX engineers developed patented technologies

to accurately translate the sound from a movie

theater environment into the home, correcting the

tonal and spatial errors that occur.

When the THX mode of the SR7500 is on, three

distinct THX technologies are automatically

added:

Re-Equalization-restores the correct tonal balance

for watching a movie in a home environment.

These sounds are otherwise mixed to be brighter

for a large movie theater. Re-EQ compensates for

this and prevents the soundtracks from being

overly bright and harsh when played in a home

theater.

Timbre Matching-filters the information going to

the surround speakers so they more closely match

the tonal characteristics of the sound coming from

the front speakers.

This ensures seamless panning between the front

and surround speakers.

Adaptive Decorrelation-slightly changes one

surround channel’s time and phase relationship

with respect to the other surround channel.

This expands the listening position and creates

with only two surround speakers the same

spacious surround experience as in a movie

theater with multiple surround speakers.

The Marantz SR7500 was required to pass a

rigorous series of quality and performance tests, in

addition to incorporating the technologies

explained above, in order to be THX certified by

Lucasfilm Ltd.

THX requirements cover every aspect of

performance including pre-amplifier and power

amplifier performance and operation, and

hundreds of other parameters in both the digital

and analog domain.

Movies which have been encoded in Dolby Digital,

DTS, Dolby Pro Logic, stereo and Mono will all

benefit from the THX mode when being viewed.

The THX mode should only be activated when

watching movies which were originally produced

for a movie theater environment.

This is because they were originally mixed for a

small room environment.

THX is a trademark or registered trademark of THX

Ltd. Surround EX is a jointly developed technology

of THX and Dolby Laboratories, Inc. and is a

trademark of Dolby Laboratories, Inc. Used under

THX Surround EX—Dolby DIgital Surround EX is a

joint development of Dolby Laboratories and THX

Ltd.

In a movie theater, film soundtracks that have been

encoded with Dolby Digital Surround EX

technology are able to reproduce an extra channel

which has been added during the mixing of the

program. This channel, called Surround Back,

places sounds behind the listener in addition to the

currently available front left, front center, front

right, surround right, surround left and subwoofer

channels. This additional channel provides the

opportunity for more detailed imaging behind the

listener and brings more depth, spacious

ambience and sound localization than ever before.

Movies that were created using the Dolby Digital

Surround EX technology, when released into the

home consumer market may exhibit wording to that

effect on the packaging. A list of movies created

using this technology can be found on the Dolby

web site at www.dolby.com. A list of available

DVD software titles encoded with this technology

an be found at www.thx.com.

Only receiver and controller products bearing the

THX Surround EX logo, when in the THX Surround

EX mode, faithfully reproduce this new technology

in the home. This product may also engage the

THX Surround EX mode during the playback of 5.1

channel material that is not Dolby Digital Surround

EX eocnded. In such case, the information

delivered to the Surround Back channel will be

program dependent and may or may not be very

pleasing depending on the particular soundtrack

and the tastes of the individual listener.

“SURROUND EX™” is a trademark of Dolby

Laboratories. Used under authorization.

DTS was introduced in 1994 to provide 5.1

channels of discrete digital audio into home theater

systems.

DTS brings you premium quality discrete

multichannel digital sound to both movies and

music.

DTS is a multichannel sound system designed to

create full range digital sound reproduction.

The no compromise DTS digital process sets the

standard of quality for cinema sound by delivering

an exact copy of the studio master recordings to

neighborhood and home theaters.

Now, every moviegoer can hear the sound exactly

as the moviemaker intended.

DTS can be enjoyed in the home for either movies

or music on of DVD’s, LD’s, and CD’s.

“DTS” and “DTS Digital Surround” are registered

trademarks of Digital Theater Systems, Inc.

The advantages of discrete multichannel systems

over matrix are well known.

But even in homes equipped for discrete

multichannel, there remains a need for high-quality

matrix decoding. This is because of the large

library of matrix surround motion pictures available

on disc and on VHS tape; and analog television

broadcasts.

The typical matrix decoder of today derives a

center channel and a mono surround channel from

two-channel matrix stereo material. It is better than

a simple matrix in that it includes steering logic to

improve separation, but because of its mono,

band-limited surround it can be disappointing to

users accustomed to discrete multichannel.

Neo:6 offers several important improvements as

follow,

• Neo:6 provides up to six full-band channels of

matrix decoding from stereo matrix material.

Users with 6.1 and 5.1 systems will derive six

and five separate channels, respectively,

corresponding to the standard home-theater

speaker layouts.

• Neo:6 technology allows various sound

elements within a channel or channels to be

steered separately, and in a way which follows

naturally from the original presentation.

the subtlety and integrity of the original stereo

recording.

DTS-ES Extended Surround is a new multichannel

digital signal format developed by Digital Theater

Systems Inc. While offering high compatibility with

the conventional DTS Digital Surround format,

DTS-ES Extended Surround greatly improves the

360-degree surround impression and space

expression thanks to further expanded surround

signals. This format has been used professionally

in movie theaters since 1999.

In addition to the 5.1 surround channels (FL, FR,

C, SL, SR and LFE), DTS-ES Extended Surround

also offers the SB (Surround Back) channel for

surround playback with a total of 6.1 channels.

DTS-ES Extended Surround includes two signal

formats with different surround signal recording

methods, as DTS-ES Discrete 6.1 and DTS-ES

Matrix 6.1.

“DTS”, “DTS-ES and “Neo:6” are trademarks of

Digital Theater Systems, Inc.

The stereo CD is a 16-bit medium with sampling at

44.1 kHz. Professional audio has been 20- or 24-

bit for some time, and there is increasing interest in

higher sampling rates both for recording and for

delivery into the home. Greater bit depths provide

extended dynamic range. Higher sampling rates

allow wider frequency response and the use of

anti-alias and reconstruction filters with more

favorable aural characteristics.

DTS 96/24 allows for 5.1channel sound tracks to

be encoded at a rate of 96kHz/24bits on DVD-

Video titles.

When DVD-video appeared, it became possible to

deliver 24-bit, 96 kHz audio into the home, but only

in two channels, and with serious limitations on

picture. This capability has had little use.

DVD-audio allows 96/24 in six channels, but a new

player is needed, and only analog outputs are

provided, necessitating the use of the D/A

converters and analog electronics provided in the

player.

DTS 96/24 offers the following:

1. Sound quality transparent to the original 96/24

master.

2. Full backward compatibility with all existing

decoders. (Existing decoders will output a 48

kHz signal)

3. No new player required: DTS 96/24 can be

carried on DVD-video, or in the video zone of

DVD-audio, accessible to all DVD players.

4. 96/24 5.1-channel sound with full-quality full-

motion video, for music programs and motion

picture soundtracks on DVD-video.

Dolby Digital identifies the use of Dolby Digital

audio coding for such consumer formats as DVD

and DTV. As with film sound, Dolby Digital can

provide up to five full-range channels for left,

center, and right screen channels, independent left

and right surround channels, and a sixth (“.1”)

channel for low-frequency effects.

Dolby Surround Pro Logic

II

is an improved matrix

decoding technology that provides better spatiality

and directionality on Dolby Surround program

material; provides a convincing three-dimensional

soundfield on conventional stereo music

recordings; and is ideally suited to bring the

surround experience to automotive sound. While

conventional surround programming is fully

compatible with Dolby Surround Pro Logic

II

decoders, soundtracks will be able to be encoded

specifically to take full advantage of Pro Logic

II

playback, including separate left and right

surround channels. (Such material is also

compatible with conventional Pro Logic decoders.)

Dolby Digital EX creates six full-bandwidth output

channels from 5.1-channel sources. This is done

using a matrix decoder that derives three surround

channels from the two in the original recording.

For best results, Dolby Digital EX should be used

with movies soundtracks recorded with Dolby

Digital Surround EX.

About Dolby Pro Logic

II

x

Dolby Pro Logic IIx technology delivers a natural

and immersing 7.1-channel listening experience to

the home theater environment. A product of

Dolby's expertise in surround sound and matrix

decoding technologies, Dolby Pro Logic II x is a

complete surround sound solution that maximizes

the entertainment experience from stereo as well

as 5.1-channel encoded sources.

Dolby Pro Logic IIx is fully compatible with Dolby

Surround Pro Logic technology and can optimally

decode the thousands of commercially available

Dolby Surround encoded video cassettes and

television programs with enhanced depth and

spatiality. It can also process any high-quality

stereo or Advanced Resolution 5.1-channel music

content into a seamless 6.1- or 7.1-channel

listening experience.

The Dolby Headphone technology provides a

surround sound listening experience over headphones.

When listening to multichannel content such as

DVD movies over headphones, the listening

experience is fundamentally different than

listening to speakers. Since the headphone

speaker drivers are covering the pinna of the ear,

the listening experience differs greatly from

traditional speaker playback. Dolby utilizes

patented headphone perspective curves to solve

this problem and provides a non-fatiguing,

immersive, home theater listening experience.

Dolby Headphone also delivers exceptional 3D

audio from stereo material.

Circle Surround II (CS-II) is a powerful and

versatile multichannel technology. CS-II is

designed to enable up to 6.1 multichannel surround

sound playback from mono, stereo, CS encoded

sources and other matrix encoded sources. In all

cases the decoder extends it into 6 channels of

surround audio and a LFE/subwoofer signal. The

CS-II decoder creates a listening environment that

places the listener “inside” music performances

and dramatically improves both hi-fi audio

conventional surround-encoded video material.

CS-II provides composite stereo rear channels to

greatly improve separation and image positioning–

adding a heightened sense of realism to both audio

and A/V productions.

CS-II is packed with other useful feature like dialog

clarity (SRS Dialog) for movies and cinema-like

bass enrichment (TruBass). CS-II can enable the

dialog to become clearer and more discernable in

movies and it enables the bass frequencies

contained in the original programming to more

closely achieve low frequencies–overcoming the

low frequency limitations of the speakers by full

octave.

HDCD® (High Definition Compatible Digital ®) is a

patented process for delivering on Compact Disc

the full richness and details of the original

microphone feed.

HDCD encoded CDs sound better because they

are encoded with 20-bits of real musical

information as compared to 16-bits for all other

CDs.

HDCD overcomes the limitation of the 16-bit CD

format by using a sophisticated system to encode

the additional four bits onto the CD while remaining

completely compatible with the CD format.

When listening to HDCD recordings, you hear

more dynamic range, a focused 3-D sound stage,

and extremely natural vocal and musical timbre.

With HDCD, you get the body, depth and emotion

of the original performance not a flat, digital

imitation.
