servicingtoqualifiedservicepersonnel.Servicingisrequiredwhentheamplifierhasbeendamagedin

anyway.Forexampleifthepower‐supplycordorplughavebeendamaged,ifliquidhasbeenspilledor

objectshavefallenintotheamplifier,iftheamplifierhasbeenexposedtorainormoisture,ifithasbeen

droppedorifitdoesnotoperatenormally.



CAUTION:Topreventfirehazard,whenconnectthespeakerstotheamplifier'soutputjacks,onlycanuse

dedicatedspeakercable.Usingothercablesmaycausefire.Cablingshouldberoutedawayfrompotential

1.2PRECAUTIONSREGARDINGINSTALLATION



Placingandusingtheamplifierforlongperiodsoftimeonheatgeneratingsourceswillaffectits

performance.Avoidplacingtheamplifieronheatgeneratingsources.Installthisamplifierasfaraspossible

fromtunersandTVsets.Anamplifierinstalledincloseproximityofsuchequipmentmayexperiencenoiseor

genericperformancedegradation.



WARNING:Topreventfireorelectricshock:



Theventilationopeningsmustnotbeimpededbyanyitemsuchasnewspapers,tablecloths,curtains

etc;keepadistanceofatleast20‐inchfromthefrontandrearventilationopeningsoftheamplifier.

Donotexposethisamplifiertorainormoisture.

Thisequipmentmustnotbeexposedtodrippingorsplashingliquids:objectsfilledwithliquids,suchas

vases,mustnotbeplacedontheamplifier.



1.2.1SafetyRules



Thisdevicemustbepoweredexclusivelybyearthconnectedmainssocketsinelectricalnetworks

complianttotheIEC364orsimilarrules.

Itisabsolutelynecessarytoverifythisfundamentalrequirementofsafetyand,incaseofdoubt,require

anaccuratecheckbyqualifiedpersonnel.

Themanufacturercannotbeheldresponsiblefordamagescausedtopersons,thingsordataduetoan

improperormissinggroundconnection.

Beforepoweringthisamplifier,verifythatthecorrectvoltageratingisbeingused.

Verifythatyourmainsconnectioniscapableofsatisfyingthepowerratingsofthedevice.

Donotspillwaterorotherliquidsintoorontheamplifier.

Donotusethisamplifieriftheelectricalpowercordisfrayedorbroken.

Donotremovethecover.Failingtodosowillexposeyoutopotentiallydangerousvoltage.

Nonakedflamesourcessuchaslightedcandlesshouldbeplacedontheamplifier.

Provideasectioningbreakerbetweenthemainsconnectionsandtheamplifier.Suggesteddeviceis

16A/250VAC,CorDcurve,10KA.

Contacttheauthorizedservicecenterforordinaryandextraordinarymaintenance.

1.2.2SpeakerDamage



FocuxClassDamplifiersareamongthemostpowerfulprofessionalamplifiersavailableandarecapableof

producingmuchmorepowerthanmanyloudspeakerscanhandle.Itistheuser’sresponsibilitytouse

speakerssuitabletotheamplifierandtousetheminasensiblewaythatwillnotcausedamage.



Focuxwillnotbeheldresponsiblefordamagedspeakers.Consultthespeakermanufacturerforpower

handlingrecommendations.



Evenifyoureducethegainusingtheamplifier’sfrontpanelattenuationcontrols,itisstillpossibletoreach

fulloutputpoweriftheinputsignallevelishighenough.



Asinglehigh‐powertonecandamagehighfrequencydriversalmostinstantaneously,whilelowfrequency

driverscanusuallywithstandveryhigh,continuouspowerlevelsforafewsecondsbeforetheyfail.Reduce

powerimmediatelyifyouhearanyspeaker“bottomingout”‐harshpopsorcrackingdistortionthatindicate

thatthespeakervoicecoilordiaphragmisstrikingthemagnetassembly.



Focuxrecommendsthatyouuseamplifiersofthispowerrangeformoreheadroom(cleanersound)rather

thanforincreasedvolume.



1.2.3SpeakerOutputShockHazard



AClassDamplifieriscapableofproducinghazardousoutputvoltages.Toavoidelectricalshock,donot

touchanyexposedspeakerwiringwhiletheamplifierisoperating.



ThismanualcontainsimportantinformationonoperatingyourFocuxamplifiercorrectlyandsafely.Please

readitcarefullybeforeoperatingyouramplifier.Ifyouhaveanyquestions,contactyourFocuxdealer.

3.2Coolingdescription

Thisdigitalamplifierseriesisdesignedaccordingtointernational1Usizestandards.Thecoolingmethodis:

pumpingtheoutsideairintotheunitthroughtheventsofthefrontpanel,andthenbringouttheheat

throughthealuminumradiatorintheunitandthenoutfromtherearpanelvents.The"smart"variable

detectionandcircuitdetectionfortheheatsinkmodule.Whentheunitinsideoverheats,itwilladjustthefan

speedtoincreasecoolingefficiencyimmediately.



Ifanyheat‐sinkoverheats,thedetectioncircuitwillreduceoutputpower.Iftheamplifieroverheats,the

temperatureprotectiondetectioncircuitanditscircuitwillshutdownandpoweroffuntilitcoolstoasafe
