Relay outputs:
Inadditiontothestandardaudiooutputs,theM2alsocontains 8 relay outputs.Eachof
theserelayscontainnormallyclosed(NC)andnormallyopen(NO)contactswhichcanbe
connectedusingTerminal Block connectors.
Theserelayscanbetriggeredautomatically when a paging message is announcedfora
certainzone,whenapriority signal or contact occurs,atpre-defined timer scheduled
momentsorbypushing freely programmable buttons on a paging console.
Averydiverserangeofexternaldevicescanbecontrolledusingtheserelays.Sometypical
applicationexamplesareoverrulingmanual100Voltvolumecontrollersandactivating
emergencylightsincaseofemergencycalls.Otheroptionsareswitchingonpower-amplifiers
atpre-definedmoments,powering-updisplaysorbeamerstogethertheaudiosystem,rolling
andunrollingofautomaticprojectionscreens,turninglightsonandoff,...
Infact,theserelayoutputscanbeusedforcontrollingandpoweringdevicesinamuchwider
applicationrangeasdescribedabove,aslongasthevoltageandcurrentdoesnotexceed
theallowablelimitof1A / 30V DC or 0.3 A / 125V AC.
Contact inputs:
Atotalof10 contact inputsareprovided,whichcanbeusedfortriggeringalldifferent
kindsofactionsandeventsbyasimple contact closure.Someexamplesoftriggerable
actionsare ‘Scenes’ selection, Output zones linking, priority actions triggering,
voice file enabling, ...
Eightoftheseinputsaregroupedunder‘Contact Inputs’andimplementedusinga
9-PinTerminalBlockconnector.Thesecontactscanbetriggeredbyconnectingthe
common(C)terminalwiththecorrespondingterminal(1to8)ofthecontactsinput.
Theother twocontactinputsaregroupedunder‘Priority Inputs’andimplementedusing
2-PinTerminalBlockconnectors.Thesecontactscanbetriggeredbyconnectingboth
terminalspinstoeachother.
Priority inputs:
Two balanced priority audio inputsarefeaturedusing3-PinTerminal Block
connectors.ThesepriorityaudioinputsacceptbothLineandMicrophonelevelsignals
andcanbeusedforconnectinganymonoaudiosourcedevicesuchasexternalvoicefile
interfaces,telephonepageroutputs,...
Theactionstobetakenincaseofapriorityinputcanbefreelyprogrammedand
configuredforeachoutputindividually.
Peripheral interface connectors:
Atotalof10 Peripheral interface connectorsarepresent,providedwithRJ45
connectors.ThisallowsexpansionofthesystemwithperipheralunitssuchasWallPanel
controllers(possiblycontainingadditionallocalaudioinputs),digitalpagingmicrophones,
intelligentrelayunits,...
AllthePI ports (1 to 10)supportbi-directional RS485 data transferupto32 devices
connectedtoeach PI port,whileonlythe8firstPI ports (1 to 8)supportdata + digital
audio transfer. Thisway,audioinputscanbeconnected,whichcanbepatchedtothe
mixer.
