Rear Panel overview
Rear panel description
TherearpaneloftheCAPseriesslightlyvariesdependingoftheoutputconfigurationand
powerrating,butbasicallythepanellayoutforallCAPamplifiersissimilar.AnXLRinput
connectorwithXLRlink-throughoutputconnector,ahighpassfilterswitch,againcontrol
potentiometerandanterminalblockoutputconnectorareprovidedforeverychannel.
AC Power inlet with fuse
Themainspowersupply(100~240VAC/50~60Hz)hastobeappliedtothisACpower
inlet.TheconnectionismadebyanIECpowerconnectorandisfittedwithafuse.When
replacingthefuse,makesurethatthevalueofthereplacementfusematchesthevalueof
theoriginalfuse.(CAP224:T4AH/250V-CAP248:T6.3AH/250V-CAP424:T6.3AH/250V
-CAP448:T12AH/250V)
High pass filter switch
Bymeansofthisswitch,theintegratedHighPassFilter(HPF)canbeswitchedONand
OFF.WhenthefilterisswitchedON,frequenciesbelow400Hzwillbesuppressed.
Thiscanbeusefulforeliminatinglow-frequencyhumandnoisecausedbyexternal
equipmentandprotectsspeakersfromdamagecausedbyexcessivelowfrequency
transients.
Gain control potentiometer
Eachchannelisfittedwithagaincontrolknobwherebythelevelforeachindividual
channelcanbeadjusted.
Loudspeaker connections
Theloudspeakeroutputconnectionsareperformedusing4-pinterminalblock
connectors,makingitpossibletoconnecthighimpedance(100V)loudspeakerstothe
amplifieroutputs.
Input connections
TheinputconnectionsoftheamplifierareperformedusingbalancedXLRconnectors.
EverychannelhasaXLRinputconnectorandaXLRlinkoutputconnector.Theinput
signalfromthesignalsource,pre-amplifierormixershouldbeconnectedtotheXLR
inputconnections.AndbymeansoftheXLRlinkoutputconnectors,thesignalcanbe
linkedthroughtomultipleamplifiers.
