ENABLING THX SURROUND EX™ DECODING
THX .Surround .EX™ .processing .creates .back .chan-
nel .material .from .material .contained .in .the .sur-
round .channels .of .Dolby .Digital .5 1 .bitstreams .
Some .Dolby .Digital .material .has .been .formatted .
so .that .THX .Surround .EX™ .processing .is .applied, .
specific .material .will .be .placed .on .the .back .chan-
nels, .while .other .specific .material .remains .on .the .
surround .channels .To .control .when .THX .Surround .
EX™ .processing .will .be .applied, .change .the .EX .
Control .setting .as .follows: .
. 1: . . First .enter .the .main .menu .by .pressing .on .any .
one .of .the .menu .buttons .(< .- .> .or .SELECT) .
. .
.
2: . . Next .move .the .cursor .to ."OS" .Hit .'SELECT'; . .
you .are .now .in .the .'Other .Settings' .menu
. .
. 3: . . Move .the .cursor .to ."EX" .Hit .'SELECT'; .you .can .
now .change .the .EX .Control .setting .
. .
The .options .available .in .this .menu .are: .
. ● . DISABLE: . . THX .Surround .EX™ .will .not .be .
decoded .
● . ON: . . THX .Surround .EX™ .will .be .forced .
on .for .all .Dolby .Digital .5 1 .channel .
input .bitstreams, .if .the .back .chan-
nels .are .enabled
● . AUTO: . . THX .Surround .EX™ .will .be .decod-
ed .if .the .incoming .Dolby .Digital .
bitstream .is .flagged .as .having .
THX .Surround .EX™ .encoded .con-

CHANGING DOLBY PLII MUSIC SETTINGS

Dolby .Pro .Logic .II .is .the .next .generation .in .Dolby .
Surround .decoding .It .is .designed .specifically .
to .decode .all .existing .Dolby .Surround .programs .
and .provide .improved .spatiality .and .directional-
ity .of .sounds .Through .the .use .of .an .elegant .new .
approach .to .matrix .surround .decoding .and .the .
decoding .of .stereo, .full-bandwidth .surround .out-
puts, .Pro .Logic .II .decoding .effectively .bridges .the .
gap .between .Pro .Logic .and .discrete .Dolby .Digital .
5 1 .soundtracks .
Pro .Logic .II .is .also .designed .for .use .with .unencod-
ed .stereo .music .recordings .The .listener .is .drawn .
into .a .three-dimensional .space, .rather .than .hearing .
a .flat, .two-dimensional .presentation .This .not .only .
helps .develop .a .more .involving .soundfield, .but .also .
solves .the .narrow ."sweet .spot" .problem .of .conven-
tional .stereo .reproduction .All .of .these .benefits .are .
provided .using .the .same ."3/2" .speaker .configura-
tion .consumers .have .been .using .with .Pro .Logic .
since .1988 .
Pro .Logic .II .follows .in .the .footsteps .of .Pro .Logic .
and .Dolby .Digital .5 1 .channel .decoding .In .many .
key .respects, .Pro .Logic .II .fits .into .this .environment .
seamlessly .Electrically, .the .parameters .of .head-
room, .reference .level, .channel .calibration, .output .
trim .controls, .noise .sequencer, .and .master .volume .
control .are .all .unchanged .relative .to .a .Pro .Logic .
decoder .within .a .5 1 .channel .Dolby .Digital .decoder .
The .main .difference .is .that .besides .the .stereo .sur-
round .outputs, .Pro .Logic .II .provides .some .new, .
optional .modes .to .enhance .music .playback .
PLII Film: . This .is .the .preferred .decoding .
method .for .watching .movies .with .matrix .surround .
encoding .The .centre .width .and .dimension .vari-
ables .are .set .and .optimized .for .this .application, .
and .cannot .be .adjusted .No .filters .are .present .on .
the .surround .channels, .and .auto-balance .is .opera-
tional .
PLII Music: . This .mode .can .enhance .normal .ste-
reo .music .recordings, .offering .a .wider .soundstage .
and .enhanced .spatial .effects . .This .offers .user .con-
trol .over:
. 1: . C enter Width Control allows .variable .adjust-
ment .of .the .center .image .so .it .may .be .heard .
only .from .the .center .speaker, .only .from .the .
left/right .speakers .as .a ."phantom" .center .
image, .or .various .combinations .of .all .three .
front .speakers .For .home .users, .it .allows .
improved .blending .of .the .center .and .main .
speakers, .or .to .control .the .sense .of .image .
width, .or ."weight " .
. 2: . . Dimension Control .allows .the .user .to .gradu-
ally .adjust .the .soundfield .either .towards .the .
front .or .towards .the .rear .This .can .be .useful .to .
help .achieve .a .more .suitable .balance .from .all .
the .speakers .with .certain .recordings
