6: MENU CONTROL BUTTONS
SEL
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 .
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
7: SOURCE SELECT BUTTONS & INDICATORS
TV/SAT TAPE DVD CD AUX VCR
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 .
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
MODE
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 .
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 .
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
SURROUND
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-
tional .post-processing .For .2-channel .source .
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
STEREO
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-
tional .stereo
11: MONO & MONO DOwNMIX MODE
MONO
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-
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-
