1.Whilethesubwooferisinstandbymode,fliptheswitchto‘ON’tobringthesubwoofertofullpower,and‘OFF”toreturnit

tostandbymode.



2.Withthesubwooferinstandbymode,settheswitchto‘AUTO’.Whenthesubwoofersensesanaudiosignalfromthe

preamplifier/processor,itwillautomaticallygotofullpower(modethismaytaketwoorthreeseconds).Aftertenminutes

withnoaudiosignal,thesubwooferwillreturntostandbymode.ThetenminutedelayallowsforyoutochangeCD’s,pause



ConnectionConsiderations



UltraSeriesSubwoofersfeaturebothbalancedandunbalancedconnections(page10,points1&2).XLRconnectionsare

balancedlines,andaredesignedtorejectexternalnoise(frompowercables,EMIandRFIemissions,etc.)toagreaterdegree

thanstandardRCAconnections.Ifyourpreamplifier/processorisequippedwithabalancedsubwooferoutput,itis

recommendedthatyouuseanXLR/Balancedinterconnecttoassurethehighestdegreeofnoiseimmunity.



Beforesettingupyournewsystem,pleaseconsiderthefollowing:



• AlwaysmakesurethesubwooferisturnedoffbeforemakingorchangingANYconnections.

• Wheneverpossible,routethepowercordsawayfromthesignalcablesorspeakerwirestopreventhumor

PlacementTips



Whereyouplaceyoursubwooferisasimportantasanyofthevolumeorlowpasssettings.Thisisbecausetheroomitself,

othergear,andevenfurniturecangreatlychangethewaysoundwavespropagateinyourlisteningarea.Certainareasin

yourroommaymagnifytheresonantlowfrequencies,andcertainareasmayminimizethem.Walls,cabinets,shelves,and

otherfurnituremayproduceunwanted‘booming’frequencies.Proximityisusuallytheissueinthiscase.Simplymovingthe

UsingLowPassFiltersandSettingtheCrossoverFrequency



Note:Ifyourpreamp/processorhasitsownLowPassFilter/Crossoversettings,itisrecommendedthatyouusethemto

controlthecrossoverfrequencyonyoursubwoofer.TurntheLowPassFilterswitchto‘BYPASS’(page10,point3).This

disengagesalllowpass/crossovercontrolsonthesubwoofer.Ifyourpreamplifier/processordoesnothaveLowPass

Filter/Crossovercontrols,usethecontrolsonthesubwoofer.



TousetheUltraSubwooferLowPassFilterandCrossoverControls,connectthesubwoofertoyourmulti‐channelorstereo

system(withallotherspeakersconnectedtotheirrespectiveamplifiersandinworkingorder).TurnthesubwooferVolume

control(page10,point5)onthe‘MIN’(minimum)setting,thenbringthesubwoofertofullpower,andobservethefollowing

steps:



1.TurntheLowPassFilterswitchto‘ON’



2.SettheCrossoverFrequencyto150Hz,thehighestpoint.



3.Withyourpreamplifier,processor,CDplayer,orothermediasource,selectandplayafamiliarpieceofmusic.



4.Keepingthesubwoofervolumedown,raisethevolumeoftherestofthesystemspeakerstoalevelthatisrepresentative

ofyourusuallisteninghabits.



5.UsingthesubwooferVolumecontrol,raisethelevelofthesubwooferuntilitsoundscorrecttoyou(‘correct’inthiscase

referstoyourpersonalpreference).



6.BegintoslowlyadjusttheCrossovercontroltolowernumbers,takingtimetostepbackandlisten.



Rememberthatthecrossoverfrequencydefineswhichfrequenciesarepassedthroughthesubwoofer,andwhicharenot.A

crossoversetto50Hzonlyallowsfrequenciesof50Hzorlowertopassthroughthesubwoofer.Thehigherthesetting,the

morefrequenciesareallowedtopassthrough.ThehighestsettingontheUltraSubwooferis150Hz,whichallowsall

frequenciesbeneath150Hztopassthrough.



Asyoulisten,youarelookingforthemomentwhenthesubwooferseamlesslyintegrateswiththerestofyourspeaker

system.Thesubwoofershouldnotdrawattentiontoitself,butratherseemlikeanextensionofthespeakers,perfectly

blended.Smallersystemspeakerswhichproducearelativelysmallamountofbassfrequenciesmaybenefitfromahigher

crossoverfrequency,whilesystemspeakersthatproducemorebassfrequenciesmaypromptyoutochoosealower

crossoversetting.



YouwillprobablymakeseveraladjustmentstoboththeCrossoverandVolumecontrolsbeforethesubwoofersounds

properlyintegratedwithyoursystem.Besuretotakeafewbreakstorestyourears,andtryseveralpiecesoffamiliarmusic.



Remember,therearenorules.Youmayfavormoreorlessbassthansomeoneelse,andwhatsoundscorrecttoyoumaynot

soundcorrecttoothers.



AdjustingthePhasecontrolmayrequirethatyougothroughthisprocessagainaftertheadjustment.Justbepatientand

you’llgetitright!



SettingthePhaseControl



Beginbysettingthecontrolto0,andstepbacktolisten.Doesthesubwooferdrawattentiontoitslocation,ratherthan

seemlikeanextensionoftheoverallsoundstage?Doesitseemsomewhatdisconnectedfromtherestofthespeakers?Ifso,

begintoturnthePhasecontrol,takingtimetostepbackandlisten,untilthe‘imaging’seemscorrect,andthesubwoofer

blendsintothesoundstageandsoundscorrecttoyou.

UsingMultipleSubwoofersinaMulti‐ChannelSystem



ThecompactsizeofUltraSubwoofersmakethemidealforbeingusedinsystemsthatemploymultiplesubwoofers.Thisis

becomingmorecommoninhometheaterenvironments.Actionfilmsandconcerts,especially,cangreatlybenefitfroma

substantialsubwoofersetupthateasilyandcomfortablyfillstheroomduringdemandinglowendsequences.Themost

commonmultiplesubwoofersetupistheuseoftwosubwoofers,aleftsideandarightside,butmanycombinationsare

possible.Ifyouwouldliketouseamultiplesubwoofersetup,checkyouraudio‐videoprocessororreceiverandmakesureit

hasmultiplesubwooferoutputs.



Werecommendthatyouinitiallytryaleftside/rightsidesetup.Althoughlowfrequencysoundwavesarenon‐directionalin

nature,aleftside/rightsidesetupcangiveyouatrulycohesive,powerful,smooth,andbalancedsoundstage.



Setthecrossover,phaseadjustment,andvolumecontrolsidentically,thenmakeadjustmentsuntilthesubwoofersproperly

integratetoyoursystem.Ifyouareplacingthesecondsubwoofersomewhereelseintheroom(otherthanamirror

placementinrelationtothefirstsubwoofer),orusingmorethantwosubwoofers,experimentingwithvolume,crossoverand

phasecontrolsbecomescrucialinachievingabalanced,well‐integratedsoundforyoursystem.



Again,practicepatience!Itmaytakealittletime,butyou’llendupwithanamazingsoundinghometheaterandmusic

listeningenvironment.



NOTE:Whenusingamultiplesubwoofersetupthatrequiresdifferentvolume,crossoverandphasesettingsbetweenthe

subs,remembertousetheadjustmentcontrolsonthesubwoofersthemselves,insteadofsettingthemtobypassandusing

thecontrolsonyourprocessororpreamplifier.
