Precautionsregardinginstallation
WARNING:
Placingandusingtheamplifierforlongperiodsonheat-generationsourceswillaffectperformances. 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tosuchequipmentmaycausenoiseordegradationofthepicture.
Topreventfireorelectricshock:
Theventilationshouldnotbeimpededbycoveringtheventilationopeningswithitemssuchnewspapers,
table-clothes,curtainsetc.
Donotexposethisequipmenttorainormoisture.
Apparatusshallnotbeexposedtodrippingorsplashingandnoobjectsfilledwithliquids,suchasvases,shall
beplacedontheapparatus”.

ThisdevicemustbepoweredexclusivelybyearthconnectedmainssocketsinelectricalnetworkscomplianttotheIEC
364orsimilarrules.
Isabsolutelynecessarytoverifythisfundamentalrequirementofsafetyand,incaseofdoubt,requireanaccurate
checkbyaqualifiedpersonnel.
Theconstructorcannotbeconsideredresponsibleforeventualdamagescausedtopersons,thingsordataforthe
missingofaccurateearthlink.
Beforepoweringthisdeviceverifythattheamplifierissuppliedwiththecorrectvoltagerating.
Verifythatyourmainsconnectioniscapabletosatisfythepowerratingsofthedevice.
Donotspillwaterorotherliquidsintoorontheunit.
Donotusethisunitiftheelectricalpowercordisfrayedorbroken.
Donotremovethecover.Removingthecoverwillexposeyoutopotentiallydangerousvoltage.
Nonakedflamesourcessuchlikelightedcandlesshouldbeplacedontheamplifier.

Caution
TheDIGAMseries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suitable
speakerswiththeamplifierandtousetheminasensiblewaythatwillnotcausedamage.Powersoftwillnotbe
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crescendo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.Powersoftrecommendsthatyouuseamplifiersofthispowerrangefor
moreheadroom(cleanersound)ratherthanforincreasedvolume.
