PhysicalPlacement/HeatConsiderations



Ultraamplifiersemployconvectioncooling,whichisveryeffectiveandcompletelynoiseless.Undernormaloperating

conditions,yourUltraamplifierwillremaincooltomildlywarm,butconsiderationsforheatshouldbetakenintoaccount

duringplacement.



Placeyouramplifieronaflat,levelsurface,withtheweightdistributedequallyonallfourfeet.Ifusingacabinetorshelf,

pleasemakesurethatthereissufficientventilationandthereisatleast6inchesoffreeairspaceabovetheamplifierand3

inchesoneachside.Ifadequateventilationisnotavailable,yourmayconsiderinstallingtwosmallbrushlessDCfans(suchas

thoseusedincomputercases)toprovidecontinuousairflowaroundtheunit.Iftheamplifierislocatedonacarpeted

surface,placeaboardundertheamplifier’sfeet.



NOTE:Expansionandcontractionoftheamplifier’sheatsinksmaycauseafaint‘clicking’soundattimes.Thisisrelativeto

howwarmtheheatsinksbecomeandhowquicklytheycool.Thisiscompletelynormal,andnocauseforconcern.



DoNOTblocktheventilationholesontheamplifier.



YourUltraamplifierisequippedwithamassivetoroidalpowertransformer.Thistransformergeneratesamagneticfieldthat

couldinduceahuminaturntable(particularlyaturntableequippedwithamovingcoilcartridge).DoNOTplaceaturntable

directlyaboveordirectlyadjacenttotheamplifier.



Beforeplacingtheamplifieronashelf,verifythattheweightbearingcapacityoftheshelfis80lbsorgreater.Theamplifieris

heavyandshouldbeplacedtowardthebottomofanaudioracktominimizetherackbeingunnecessarilytopheavy.
