Bryston SP2 Menu Control Buttons, Source Select Buttons & Indicators, Mono & Mono Downmix Mode

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 .

SEL 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

Pressing .any .one .of .these .

		buttons .will .instantly .switch .
		the .SP2’s .analog .and .digital .
		inputs .to .read .the .indicated .
TV/SAT DVD CD AUX VCR	TAPE	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

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-

MODE 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

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 . SURROUND 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

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 . STEREO two .channel .signals .are .passed .as .conven-

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	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-
