6: MENU CONTROL BUTTONS
These .three .buttons .labeled ."", ."", .
and ."SEL" .(SELECT) .are .used .to .con-
trol .the .menu .and .setup .functions .dis-
played .on .the .LCD .To .enter .a .menu .
mode, .you .can .press .any .one .of .these .
SEL
buttons .This .will .bring .up .the .main .
menu .Navigating .any .menu .or .sub-
menu .is .done .using .the .two .arrow .( .and .) .but-
tons .Once .the .desired .submenu .or .function .is .
highlighted, .pressing ."SELECT" .will .make .it .the .
current .menu .or .function .
. To .exit .a .menu, .or .back .up .a .step .use .the .arrow .
buttons .to .highlight .the .'X' .displayed .in .the .lower .
right .hand .corner .of .the .LCD .window .and .press .
"SELECT", .or .wait .3 .to .4 .seconds .for .the .menu .to .
time .out .and .return .to .its .previous .state

is .selected .and .switched, .the .decoder .will .auto-
matically .try .to .determine .the .new .bitstream's .type .
and .mode .
8: DIGITAL MODE SELECT BUTTON & INDICATOR
This .button .operates .as .a .three-way .toggle .
function .The .LED .immediately .above .the .
button .has .two .colors .- .RED .and .GREEN, .
and .an .OFF .mode .where .it .is .not .illuminat-
ed .
MODE
When .Digital .Mode .is .selected, .the .decoder .
will .automatically .default .to .a .digital .signal .for .the .
selected .input .if .one .is .present .
. . If .a .digital .signal .is .present .and .detected, .the .
SP2 .will .automatically .determine .the .type .of .bit-
stream .and .select .the .proper .decoding .mode .The .
indicator .LED .will .turn .green .when .this .happens .
. . If .NO .DIGITAL .SIGNAL .is .detected .the .SP2 .will .
default .back .to .the .analog .input .for .the .selected .
source .This .also .automatically .puts .the .SP2 .into .
its .Digital .Standby .Mode .When .this .occurs .the .LED .
indicator .will .turn .RED .
. . In .this .mode, .the .decoder .will .continually .check .
the .selected .source .inputs .for .the .presence .of .a .
digital .signal .If .one .is .detected, .the .SP2 .will .auto-
matically .switch .over .to .the .pre-selected .digital .
Pressing .any .one .of .these .
buttons .will .instantly .switch .
the .SP2's .analog .and .digital .
inputs .to .read .the .indicated .
source .
If .the .SP2 .is .in .its .digital .
mode, .as .soon .as .any .input .
operation .mode .for .that .source .
. . To .defeat .this .auto-digital .detect .mode .you .
must .press .the .button .again .If .you .do .the .LED .will .
go .OFF .
. . When .this .mode .of .operation .is .selected .the .
SP2 .will .look .at .ONLY .its .analog .inputs .If .a .digital .
signal .does .appear .the .SP2 .will .NOT .recognize .it .
and .will .remain .in .its .analog .only .mode .until .you .
press .the .Digital .button .again .to .either .select .the .
digital .source .or .place .the .SP2 .into .its .auto .detect .
mode .as .explained .above
9: SURROUND MODE BUTTON & INDICATOR
Pressing .this .button .will .engage .the .SP2's .
surround .listening .mode .When .this .function .
is .operational .the .LED .will .turn .green .For .
Dolby .Digital .and .DTS .bitstreams, .the .signal .
will .be .decoded .and .presented .with .no .addi-

material, .the .SP2 .will .synthesize .surround .
information .based .on .the .chosen .Surround .Mode .
(see .Appendix A: SP2 Surround Modes .for .more .
information)
10: STEREO & STEREO DOwNMIX MODE
If .this .button .is .selected .and .the .supplied .
bitstream .is .more .than .2 .channels, .the .
decoder .will .automatically .implement .a .ste-
reo .downmix .Otherwise, .analog .or .digital .
two .channel .signals .are .passed .as .conven-
STEREO
tional .stereo
11: MONO & MONO DOwNMIX MODE
If .this .button .is .selected .and .the .supplied .
bitstream .is .more .than .1 .channel, .the .SP2 .
software .will .create .a .Mono .mix .of .all .sig-
nals .If .the .centre .channel .is .present, .the .
Mono .signal .will .appear .in .the .centre .chan-
MONO
nel .If .no .centre .channel .is .present, .the .
mono .signal .will .appear .simultaneously .on .the .
Left/Right .speakers .
:
NOTE Downmix [stereo or mono] is a software
based automatic mixing function available within
the SP2. This process exists because whenever the
number of active decoder outputs or loudspeakers
selected in setup is less than the number of chan-
nels in the Dolby Digital program, some channel
combining will be necessary to present the pro-
gram on the available number of channels/loud-
speakers.
As .a .part .of .any .program's .production, .its .produc-
ers .can .set .and .adjust .the .type .and .ratios .allowed .
for .downmixing .somewhat .to .ensure .optimum .
results .without .compromising .the .full .Multichannel .
balance .This .is .accomplished .by .including .specific .
data .within .the .Dolby .Digital .bitstream .which .rep-
