Location

Placethe Full Powe~Balancedamplifier ona firm level surfaceawayfromdirt or

moisture.Whenusingcustomracksor cabinetry, keepin mindthe weightand

ventilationrequirementsfor theseamplifiers.Ideally, theamplifiershouldbe

placedascloseto the speakersaspossible.It is preferableto runlong

balancedinterconnectcablesto the amplifier andkeepthe speakercable

lengthto a minimum.Speakercableaddsimpedanceto the I-6ad the amplifier

mustdrive, regardlessof the cable’sgauge.All KRELLamplifierswill drive the

lowestimpedanceswith ease,but whenimpedanceis addeddueto long cable

lengths,amplifier poweris wastedin the cable.Longspeakercablesreducethe

maximumpowerthat canbe deliveredto the speakers.

RemoteInstallation

Someinstallations donothaveadequate,spaceor flexibility to placetheamplifier

closeto the speakers.TheFull PowerBalancedamplifierscanbesituatedin a

CabinetryConsiderations

ClassAoperationoffers tremendoussonicbenefits. Unfortunately,traditional

ClassAamplifiers dissipate a tremendousamountof heat. KRELL’spatented

SustainedPlateauBiascircuitry combatsthis characteristicandreducesthe heat

outputconsiderably.However,the Full PowerBalancedamplifierscanstill

becomequite warmundernormaloperation. TheFull PowerBalancedamplifiers

shouldbeinstalledin a locationthat providesunobstructedventilation.

IMPORTANT:Theventilation gddsonthe top of all Full PowerBalanced

amplifiersneedto beunobstructedat all timesduringoperation.Donotplace

flammablematerialontop of or beneathFull PowerBalancedamplifiers. For

installations insidecabinetry,extraventilation maybenecessary.Makesurethe

Full PowerBalancedamplifiershaveadequateair circulation. Generally,two

inchesof clearanceoneachsideof the amplifier andeight inchesof clearance

abovethe amplifier will provideadequateventilation. In moreextremeinstances,

-, smallfanscanaidin removingexcessheatfrominternal spaces-.Contactyour

dealer,distributor, or Kreil®formoreinformation.

ACPowerConsiderations

Forbestperforman¢-e,a dedicatedACpowerline ratedat a minimumof fifteen

ampsis recommendedfor eachamplifier. Formaximumpoweroutput, the Full

PowerBalanced300and600amplifiers Shouldbeoperatedfroma dedicated

twentyampACpowerline. TheFull PowerBalancedamplifiers shouldonly be

operatedwith the powercord supplied. Pleaseconsult KRELL.oryourdealer

beforeusinganydevicesdesignedto alter or stabilize the ACpowerfor the Full

PowerBalancedamplifiers.

Connections

CAUTION:Thedifferential circuitry employedwithin the Full Power

Balancedaml~lifiers requires special attention whenconnectingspeakers.

Becareful not to connectthe negativespeakerterminals together. Donot

connectthe negativespeakerterminals to ground,or attemptto bridge the

left andright channelstogether of the Full PowerBalancedstereo

amplifiers.-PleasecontactKRELL:Industriesfor assistance.

Input andOutputConnections

Caution:Whenmakingconnectionsto this componentor anyother, makesure

the poweramplifier is off andthe preamplifieris in themuteor stand-bymode.

Thewidngto andfromthe amplifier andall componentsin generalshouldbe

arrangedin a neat, organizedmanner.Specifically, ACwiresshouldbe

separatedfromaudiocables. This practice preventshumor other unwanted

noisefrombeingintroducedinto the system.

1. Connectthe speakercablesto the amplifier’s outputterminals.

TheFull PowerBalancedamplifiersutilize twocustomsetsof identical speaker

terminalsfor the eachchannel.This configurationmakescableconnectionsand

biwiring simple.Thespeakerterminalsonly acceptspadelugs. Barewire,

bananalugs, or pinswill not work.Theredterminalsareusedfor positive

connectionsandthe blueterminalsare usedfor the negativeconnections.

Either the upperor lowerset of speakerterminalsmaybeusedwith speakers

havingonepair of bindingposts.Forbiwiring, bothsetsof terminalsshouldbe

used.Consultyourspeaker’sinstruction manualfor biwiring connections.

CAUTION:Makesureall cableterminationsare of the highestquality, free from

frayedends,shorts, or poorsolderconnections.

2, C~nnectthe interconnectcablesfromyourpreamplifier,to the input of the Full

PowerBalancedamplifier.

TheFull PowerBalancedamplifiers are equippedwith balancedandsingle-

endedinputs. Thebalancedinputs usethree pin XLRconnectorsandthe

single-endedinputs use RCAconnectors. Werecommendthe useof balanced

interconnects,.sonicallyandelectrically, becauseof their immur~tyto induced

noiseandminimalsonicloss resulting fromlongcablelengths.

CAUTION:Useonly oneset of inputsto the amplifier at a time. TheFull Power

Balancedamplifiers are shippedwith shorting pins in the XLRinputs, These

pinsshouldremainin the XLRinputsif the Full PowerBalancedamplifier is

operatingin the single-endedmode.Whenthe shorting pin is inserted, pins1

and3 are shortedtogether. Theshorting pins mustbe removedto connectthe

Full PowerBalancedamplifiers for balancedoperation.

Thepin assignmentfor the XLRis:

pin 1 = shield (ground)

pin2=non_-invertinginput(hot)

pin3 =invertingin put

ForUsewith a TubePreamplifer

TheFull PowerBalancedamplifiers featuredirect couptedcircuitryfrom input to

output.Thistopologyeliminatesall couplingcapacitorsfromthe audiosignal

path. Couplingcapacitorsare usedto blockdamagingdirect current (DG)but

havesonic characteristics that impactmusicnegatively. Instead, KRELLuses

non-obtrusiveDCservosthat strip DCfromthe signal withoutcorruptingthe

music.

Tubepreamplifiers,bydesign,arecapacitivelycoupled.Forthis reason,the

benefitsof a direct coupledamplifier cannotberealized whenusedwith a tube

preamplifier.Additionally, manytubepreamplifiersoutputa greatdealof DC.

This DCmayexceedthe servosof a Full PowerBalancedamplifier. Excessive

DClevel in a signal candamageamplifiers, speakers,or both.

Tocombatthis potential problem,the Full PowerBalancedamplifiers include

internal jumpersthat insert couplingcapacitorsinto the signal path.These

capacitorsshouldbeengagedwhenusinga tubepreamplifierwith a Full

PowbrBalancedamplifier. If not utilized, KRELLreservestheright to

refuse warrantyservicedueto DCrelated damage.Pleasecontactyour

KRELLdealerfor =assistance.
