OutputConnectionConsiderations



industrystandardspacing.Thesearesometimescalled5‐waybindingpostsbecauseofthemanywaysinwhichthespeaker

wirecanconnectintotheposts.Thepostscanacceptbarewire,spadeterminals,orsinglebananaconnectors.Keepinmind

thatifyouuse“dualbanana”plugsand“stack”them,youwillbecreatingaparallelconnection.Formoredetailsonseries

andparallelconnections,seepages23‐24.



Itisimportanttoobservepolaritysothatthespeakerwireconnectstotheredandblackterminalsontheamplifierandthe

correspondingterminalsatthespeaker.Also,makesurethatthepositivespeakerwiresdonottouchthenegativespeaker

wires,oranychassismetal.Thiswillcauseashortcircuitandactivatetheprotectioncircuitry.

ConnectionTipsforSuperiorSound



Beforesettingupyournewsystem,pleaseconsiderthefollowing:



• AlwaysmakesuretheamplifieristurnedoffbeforemakingorchangingANYconnections.



• Wheneverpossible,routethepowercordsawayfromthesignalcablesorspeakerwirestopreventanyhumor

interferenceheardinthespeakers.



• ManyRCAtypepatchcordscanbeaverytightﬁtandthereisusuallyapreferredmethodofremovingthem.Some

havetoberemovedwithatwistingaction.Begentleoryoumaydamagethejacksofyouramplifier,thecables

themselves,orothercomponents.



• Manyaudiophilesignalcablesareintendedtobehookedupinonedirection.Ifthisisthecase,thecableswillbe

markedwitharrowsindicatingthedirectionofsignalflow.



• ItisusualfortherightchannelRCApatchcordplugstoberedandtheleftchannelconnectionstobewhite,grey,or

black(dependingonthecablebrand).RCAconnectorsthataregoldwillbedesignatedwithacoloredbandto
