1. Bus 12VDC Trigger In/Out
TheBus12VDCTriggerInisusedtoactivateallzonesthatare
usingtheBusInputanddisablesotherzonetriggersorsignal
sensingonthosezoneswhenitisused.WhetheBus12VDC
Triggerisused,allBus-controlledzoneLEDswillbeblueandac-
tive.IftheBusTriggerInhas12Vappliedtoit,onlythe12VBus
TriggerOutwillhave12VandtheZoneTriggerOutputswillnot.
2. Bus Inputs/Outputs
TheBusLineInputsareoptionalinputsthatcanbeusedtocon-
nectasinglesourcetomultiplezones.TheBusLineOutputsare
passivepassthroughthecorrespondingoftheBusInputsand
canbeusedtodaisychainthesourcetootherampliersinthe
system.
3. Line/Bus Switch
SwitchesthezoneinputtotheLineInput,BusInput1or
BusInput2.
4. Line Input
TheLineaudioinputforeachzoneisadedicatedsensinginput
thatwillactivatethezonewhenanaudiosignalfromasourceis
present.
5. 12VDC Trigger In/Out (Each Zone)
TheZone12VTriggerInisusedtoactivateaspeciczone.
TheZoneTriggerOutcanbeusedtotriggerother12Vdevices.
Thedelayandaudiosensingarebypassedwhenthe12VZone
TriggerInputisused.WhenaZoneTriggerisactive,thezoneLED
willbeblue.IfnovoltageispresentintheZoneTrigger,theZone
LEDwillbeo.StandbyModeTheamplierwillgointoStandby
modewhenaudiosignalortriggerisnotpresentafter3munites.
6. Speaker Outputs
Theminimumspeakerimpedanceis4ohmsforStereoModeand
8ohmsforBridgeMode.
7. Stereo/Bridge Switch
SelectstheoutputmodeofeachzoneforstereoorBridge
operation.
8. Gain Controls
LeftandRightgaincontrolsforeachzoneadjustthesoundlevel
independently.OnlyusingLeftcontroltoadjustthesoundlevel
whenusedinBridgeMode.
9. Voltage Switch
