One4Ohmandone8Ohmjackisprovidedforspeakerinterfacing.MESA/Boogiecabinetsarebuiltwiredto8
Ohmsunlesscustomorderedormodifiedbyanoutsideparty(i.e.apreviouslyownedcabinet).One8Ohmcabinetshouldbe
connectedtothe8Ohmoutput.Whenusingtwo8OhmMESAcabinets,connectonecabinettothe4Ohmoutputand“daisy
chain”thesecondcabinetbycomingoutofthefirstcabinet’sParalleledOutjackintothesecondcabinet’sinputjack(MESA
cabinetsprovideaParalleljackforthispurpose).
Ifyouareusingnon-MESAcabinetswithyourMiniRecto,itisveryimportanttoknowyour
cabinet’simpedanceandmakesureyouareconnectingspeakerscorrectlyandsafelytotheamp.
Failuretoconnectspeakerscorrectlycancauseexpensivedamagetotubes,transformersand
theampingeneral.ALWAYSmakesuretoconnectyourcabinetcorrectlytoyouramp.Checkout
theinformationlaterinthismanualregardingspeakerimpedanceandspeakerhook-upschemes.
Nomatterhowunusualyourspeakersetup,itisgenerallypossibletogetgoodperformance.
FX LOOP
YourMiniRectobenefitsfrom40yearsofhighperformanceampdesignandtheEffectsLoopfeaturedhereis
aresultofthatexperienceandexpertise.TheLoopcanbeHardBypassedforpuristswhoprefer“non-loop”designs,which
removesalltubesandcircuitryfromthesignalpath.However,eventhesetraditionalistskepticsmayhaveasurprisewhen
they,uponscrutiny,findtheyprefertheLoopActive.Ourtestshavehadthesameresults-withmostplayerspreferringthe
slightaddedthree-dimensionalityandtopendenhancementandclaritythiscircuitimpartsonthesignal.
TheEffectsLoopiswiredinSerieswiththedrysignalandaslongasyouareusingprocessorsofgoodquality,youshould
experienceseamlessinterfacingwithnotonaldegradation.Thatsaid,anythingyouinsertinthisextremelysensitivejunctionof
anamplifier(betweenpreampandpowersection)mayhavethepotentialtoslightlyalterthesound.Also,everycompanythat
buildsprocessorshastheirownwayofdoingthingsandtherearecontrolsandfeaturesthatempower,andsomethatmake
thingsmorecomplicatedwhileaddingquestionablesonicbenefit.Wesuggesttakingyourampandtryingitwiththeprocessor
youareauditioningtomakesureyouwillhavegreatperformancewhentheyarecoupled.
Whilemostpedal-typeeffectswillworkintheLoop,itisalwaysbesttoconnectoverdrive,distortion,boost,compressionand
wahorenvelopefiltereffectsbetweentheinstrumentandtheFrontEndoftheamplifier.Theseeffectsaredesignedtoalterthe
soundoftheinstrumentbeforeitisamplified,andyouwillgetbetterresultsnotusingtheLoopfortheseapplications.
AC SOCKET (Quick Disconnect Style)
ThisistheACMAINSPowerCordSocket.Thestandardizedremovablepower
cablesuppliedwithyourampcanonlybepluggedinoneway.Alwaysconnectthemaleendtoagroundedwallsocketwiththe
propervoltagepresent(117VoltsonU.S.A.Models).ToAvoidTheRiskOfSchock,NeverAlterThePowerCableinanyway.
AlteringthePowerCablewillvoidyourwarrantyandputyouatriskwhileleavingyouramplifieropentothepossibilityofdamage.
