2. Connectloopfeedcabletotheloopclampconnector(seediagram).
3. Connectthelowimpedancespeakercabletoinput1.
4. Useascreenedcable<1mtoconnectanelectretmicrophonetoinput2.
5. Observingcorrectpolarity,connecttheDCpowersupplyandapplypower(seediagram).The
powerindicatorwillilluminate.
6. Withtheinputsignalon,increasetheInputcontroluntilthegreenAGCLEDilluminateswitha
normalsignal.
7. AdjusttheOutputcontroluntiltheamberCurrentLEDisilluminatedwithsignalpeaks.
8. UseanAmpetronicFSMtotestthesystemandadjustasrequiredtobeconsistentwiththe
requirementsofthelatestIEC60118-4Standard.UsetheMLCcontroltoadjustforhigh
frequencyloss.
Fault Conditions
Overheating:Theamplierwilloutputmaxratedsinecurrentfor1minuteintoratedload.After
 thisperiodaninternalprotectionmechanismwillattenuatetheoutput.
 Overcurrent/Overvoltage:Theamplierwillshutdownifitscapabilitiesareexceededfora
 shortperiod.Theamplierwillresumenormaloperationwhenoperatedwithinthenormal
