otherdevices,andoftendiversesystemrequirements.
NADhasdevelopedtwouniquefeaturesthatendowthe
CI9060withexceptionalexibility.
CI 9060 6-Channel Power Amplier
TheNADCI9060isaclean-sheetdesign6
channelamplierspecicallyengineeredtomeet
thedemandingrequirementsoftheadvanced
custominstallationmarket.Theresultofthis
intensivedesigneffortisanamplierthatsets
newstandardsfor“bullet-proof”reliabilityand
sonicperformanceinthisspecializedcategory.
Power
Manyoftheampliersdesignedformulti-zone
distributedaudioarejustnotpowerfulenough.
TheCI9060at80WattsContinuouspowerper
channel,boastsnearlydoublethepowerofmost
othercompetingampliers.Thisisverycritical,
becauseunlikeanormalhi-amplierthatonly
hastosenditssignaltospeakersacrossroom,
custominstallationsoftendemandthatthesignal
besentfromoneendofthehometotheother.
Theseriesresistanceoflongrunsofspeaker
wirecombinedwithimpedance-matchedvolume
controlscancreatespecialdemandsonan
amplierthattheCI9060hasbeendesignedto
overcome.
OMC
NAD’sproprietaryOutputManagement
Circuit(OMC)ensuresthatthefullpoweris
availableatanyreasonableloadimpedance.
Iftheloadimpedancefallsbelow3ohms,
indicatingsomethingotherthanaloudspeaker
isconnectedtotheamplierchannel,the
OMCwilllimitthepowerowandprevent

Flex-Pad
TheFlex-PadallowstheCI9060todrivefrom1to6independent
zones,inanycongurationofstereoormono(orinmixed
combination),withoutresortingtotheconfusion,sonic
degradation,andquestionablereliabilityofswitches.Instead,the
Flex-Padusesthetriedandtruepatch-bayconcepttocongurethe
amplierchannels.Thecongurationisvisuallyobvious,making
iteasierfortechnicianstosetupthesystemandtotroubleshoot
forsystemerrors.Thesuppliedpatchcablescanbeeasily
reconguredorreplaced.Thiscanbeespeciallyimportantandcan
greatlysimplifyfutureservicecallsyearsdowntheroad(especially
ifsystemdocumentationismissingorincomplete).
ATO Logic
TheCI9060canbeturnedoninanyoneofthreeways,for
completesystemexibility:
1. Fromthefrontpanelswitch.
2. Viathe12volttriggercircuit.
3. Byaswitchable“sleep/wake”signal-sensingcircuit.
ThisismanagedbytheAutomatedTurn-OnLogic(ATOLogic)
circuitthatrequirestheampliertobeswitchedbacktostandby
inthesamemannerbywhichitwasactivated.Inotherwords,if
itisswitchedonviaa12Vcontrolsignal,itcannotbeswitchedto
standbyviathefront-panelswitch,itmustwaitforthe12Vsignal.
