Setting the Channel Delays

SP2 PREAMP/PROCESSOR

4: Once. .you .have .selected .the .desired .crossover . frequency, .press .SELECT .to .exit .this .menu .and . return .to .the .Speaker .Config .menu. .The .select- ed .frequencies .are .common .to .all .speakers . defined .as .‘SMALL’. .Crossover .frequency .can .be . set .independently .for .Front, .Centre, .Surround . and .Back .speakers.

NOTE 1: The. crossover action is only applied to speakers defined as ‘SMALL’ in the speaker configuration menu. .

In .this .step .you .will .need .to .measure .within .one . foot .the .distances .from .your .chosen .listening/view- ing .position .to .the .various .loudspeaker .locations . in .your .system. .You .will .need .the .tape .measure .or . other .means .of .making .these .measurements. .You . should .record .this .data .for .future .reference. .

. 1: Now,. .make .a .measurement .from .the .chosen . seated .position .to .each .loudspeaker. .

. 2: Next,. .enter .the .main .menu .by .pressing .on .one . of .the .menu .buttons .on .the .SP2 .front .panel. . Move .the .cursor .to .“DLY”. .Hit .‘Select’ .- .You . are .now .in .the .Delay .Menu. .The .SP2 .automati- cally .calculates .the .required .delay .time .per . speaker .using .the .data .entered .as .distance . from .the .listening .position. .Delays .are .imple- mented .using .DSP .RAM .and .have .a .maximum . value. .

IMPORTANT: .It .is .recommended .that .the .closest . speaker .is .entered .first. .The .SP2 .will .calculate .the . maximum .allowable .distance .from .the .listening . position .for .the .remaining .speakers. .Please .note . that .delay .is .represented .in .feet. .For .reference, . One .foot .(0.3048 .meters) .= .approximately .1 .milli- second .of .delay. .

. 1: Move. .the .cursor .to .the .speaker .you .want .to . set .the .distance/delay .for .(L .C .R .RS .LS .RB .LB .

SB). . .Hit .Select. .Now .you .can . adjust .the .Delay .value .which .is .equivalent .to . the .distance .you .measured .for .the .selected . speaker .using .the .arrow .buttons. .Set .the .delay . for .each .speaker .in .your .system .to .the .nearest . foot/meter. .Rounding .up .is .OK. .Remember .that . if .one .back .speaker .is .selected, .the .Left .Back . output .is .used .to .set .the .delay. .

. 2: Hit. .SELECT .or .[X] .Exit .when .finished. .The . SP2’s .default .factory .settings .as .shipped .are .

10 .feet .to .every .speaker, .resulting .in .zero .

overall .delay. .When .using .the .remote .control . to .enter .these .selections, .press .the .“SAVE” . button .before .exiting .or .settings .will .be .lost.

Calibrating and Setting Levels/Channel to Channel Balance.

. 1: Position. .the .Sound .Level .Meter .at .the .Centre . point .of .your .listening .area, .at .average .ear . height .[approximately .40 .- .46 .inches .{102 .- .

117.cm.} .with .its .microphone .positioned .verti- cally .(pointing .at .the .ceiling). .DO .NOT .aim .the . sensing .microphone .at .the .speakers, .as .this . will .produce .inaccurate .level .indications. .

. 2: Using. .the .SP2 .Remote, .press .and .hold .for . approximately .3-5 .seconds .the .key .labeled . “TEST”. .

IMPORTANT: .The .Test-Noise .Mode .can .only .be . initiated .from .the .SP2 .remote, .and .not .from .the . front .panel. .

The .shaped .pink-noise .test .signal .will .begin .with . the .left-front .loudspeaker. .If .the .signal .does .not . appear .in .this .speaker .please .stop .the .process .and . check .your .wiring .and .connections .for .proper .con- figuration. .

IMPORTANT: .When .using .the .Pink .Noise .genera- tor .within .the .SP2 .for .speaker .level .calibration, .the . salient .point .is .that .all .channels .measure .equal .dB. . After .pushing .the .test .button, .the .pink .noise .will . start .in .the .front .left .speaker. .Record .the .dB .level . from .this .speaker .(with .the .level .trim .value .at .0 . dB .on .the .LCD .Display), .and .adjust .all .the .others . to .match .it. .It .is .not .critical .to .reach .some .specific . dB .level .(ex. .85 .dB), .it .is .more .important .that .all . channels .are .at .equal .levels. .

. 1: Hit. .the .“TEST” .button .again .to .sequence .the . noise .to .the .next .speaker. .The .sequence .is .L .-

>.C .-> .R .-> .RS .-> .RB .-> .LB .-> .LS .-> .SUB .-> . EXIT. .

. 2: Using. .the .volume .up/down .arrows .on .the . remote .or .the .arrow .keys .on .the .SP2 .adjust . the .level .of .the .noise .for .each .speaker .so .that . it .matches .the .front .left .channel .noise .(dB) . level .on .the .Sound .Level .Meter. .

. 3: When. .the .cycle .is .complete, .the .test .noise .sig- nal .will .end, .and .the .unit .will .switch .back .to . the .previous .mode. .If .any .output .is .unused .(as . defined .by .‘NONE’ .in .the .Speaker .Configuration . Setup), .the .noise .sequence .will .automatically . skip .to .the .next .speaker .in .the .sequence. .

Setting Channel Levels without Pink Noise

If .you .wish .to .adjust .the .speaker .level .trims .with- out .using .the .pink-noise .test .signal, .this .can .be . done .from .the .Front .Panel .menu .system. .

. 1: First. .enter .the .main .menu .by .pressing .on .any .

one .of .the .menu .buttons .on .the .SP2 .front . panel .(< .- .> .or .SELECT). .
