“OperatingVoltage”beforeyouinstallyourSA-3.

NotethatadequateclearancefortheACcordandconnectingsignalcables

Special Design Features

Dedicated Power TheWisdomAudioamplier/speakersystemisdesignedtotakeadvantageof

afactthathashithertobeenunderstoodonlybyarelativelysmallnumberof

audiophiles:speakerssoundbetterwhentheyaredrivendirectlybydedicated,

highqualityampliers.

Youmightthinkthatyouhavedonesointhepast.Afterall,youconnected

yourreceiveroramplierdirectlytotheloudspeakercabinet,usinghighquality

wire.Butinalmostallcases,thatconnectionledtoapassivecrossovernetwork

withinthespeakercabinet,madeupofresistors,capacitorsandcoilsofwire

calledinductors.Thepassivecrossoverhadthejobofsplittingupthesignal

tothewoofer,midrange,andtweeterinsidethecabinet.Bydesign,itcreated

acomplex,reactivecircuitbetweentheamplierandthedriversthatactually

makethemusic.

TheWisdomAudioapproachdoesnotsufferfromthiscompromise.TheSC-1is

anactive(notpassive)crossoverthatdividesthemusicsignalwhilestillatapre-

amplierlevel.Itcandosowithfargreateraccuracyandconsistencythanpas-

sivecomponentsinaspeakerbox,withtheirinevitableproductiontolerances.

Theseseparatesignalsarethenroutedtodedicatedamplierswhichneedwork

withonlyaportionoftheaudiblerange.InthecaseoftheSA-3amplierchan-

nels,theyneedhandleonlythebass;themidrangeandtrebleareroutedtoa

separateamplierofyourchoosingthatdrivestheplanarmagneticpanels.

Thisapproachiscalled“bi-amplication”sinceeachspeakerisactuallyusing

twochannelsofamplication.Itprovidesseveralimportantbenets:

• Greater excitement due to improved dynamics.Obviously,

havingtwoampliersallowsyoutousemorepoweronaper-

speakerbasis,butthisisaboutmorethansimplyplayingloudly.

Themoment-to-momentdynamiccontrastsarevastlyimproved,

thankstothefactthattheinefcientbufferthatwouldhavebeen

thepassivecrossoverismissing.Theampliersareconnected

directlytotheirrespectivedrivers,soeverynuanceinthesignalis

preserved.

• Improved detail and intelligibility thanks to lower distortion.

Onemajorsourceofloudspeakerdistortion—thepassivecross-

overitself—hassimplybeeneliminated.Plus,eachamplierhas

asimplertask,beingresponsibleforonlypartoftheaudiblespec-

trum.Thisfactreducesseveraltypesofdistortion,mostnotably

clipping(sinceallofitspowerisavailableforlesswork)andinter-

modulationdistortion(sincetheamplierseesfewerfrequencies).

• Improved clarity and control.Theamplier’s“dampingfactor”

isonewayofmeasuringitsdegreeofcontroloverthemotionof

thedrivertowhichitisconnected.Unfortunately,whenapassive

crossoverintervenes,theamplierisnolongerdirectlyconnected

tothedriveritisaskedtocontrol.Asaresult,itlosesmuchofthe

precisionitsdesignersworkedsohardtoachieve.Byavoiding

theneedforapassivecrossoverandconnectingdirectlytothe

transducer,theamplier’sabilitytocontrolthemotionofthedia-

phragmismaximized.

Infact,manyWisdomAudiosystemstakethismultiple-amp-per-speakeridea

evenfurther.Whenyouaddoneormorededicatedsubwoofersthathandle

onlythedeepestbass,thesystemis“tri-amplied.”Thatis,youenjoythebene-

tsofhavingseparate,dedicatedampliersanddrivershandlingonlythedeep-

estbass,thentherestofthebass,andthenthemidrangeandhighfrequencies

(ontheplanarmagneticdrivers).

High Efciency Thebenetsofenormouspowerreservesarefairlyobvious:freedomfromany

audiblestrain,greaterdynamicimpact,andtheabilitytohearmusicandmovie

soundtracksattheirintendedvolumewithoutworryingaboutwhetherthe

systemcanhandleit.

However,thetraditionalmethodsforachievingthisrequiredlevelofperfor-

manceinvolvebulky,heavydesignsthatgenerateagreatdealofheat.When

youmultiplythenumberofchannelsrequiredforamodernhometheaterap-

plicationtimestwo(forbi-amplication),andaddinoneormorededicatedsub-

woofers,suddenlyyouhaveneedforsmaller,moreefcientamplierdesigns.

ThesystemampliersusedtodrivethewoofersectionsofyourSageseries

loudspeakersfromWisdomAudiotthebillnicely.Whilemanycontemporary

amplierswaste50%ormoreofthepowertheypullfromthewallasheat,your

SA-3amplierrunsatapproximately90%efciency.Asaresult,morepoweris

availablefortheloudspeaker,andlessiswastedasheatinyourroom.

ThehighefciencyoftheSA-seriesdesignalsomeansthattheamplierscanbe

placedincloseproximitytoeachother,asinanequipmentrack,withoutundue

overheating.Ofcourse,caremustbetakentoaccountfortheheatgenerated

byothercomponentsintherack;butyourWisdomAudioamplierswillnot

greatlycontributetothethermalmanagementchallengesofyoursystem.
