Rear Panel overview
Audio inputs:
TheM2containsatotalof9 mixable audio inputs.
8oftheseinputsareBalanced StereoinputsacceptingbothLine and Microphone level
signals.TheseinputsareimplementedusingTerminalBlockconnectors,usableforaudio
signalscomingfromanyaudiosource,whetherthesignalisBalancedorUnbalanced
andMicrophoneorLinelevel.Eachinputisperformedusinga6-pinsTerminalBlock
connector(3-pinsforeachLeftandRightchannel).
The ninth audio input isanUnbalanced Stereo input,whichisimplementedusing
RCA connectors.Thissignalisselectableoutof four stereo RCA inputs(9A,9B,9Cor
9D).Onlyoneofthesefourinputscanbeusedatthesametime.Thisinputisspecifically
implementedforapplicationsbeingusedincombinationwithmultiplevideosources,
whereonlyoneofthesesourceswillbeusedsimultaneously.Inthiscase,itprovidesthe
greatadvantageofonlylosingoneoftheinputs,insteadoffour.
WhenconnectingaMono signal source(suchasamicrophone,...)totheM2,itshould
alwaysbeconnectedtotheLeft Channel inputs(upperterminalsoftheBalancedinputs
orWhiteRCAterminaloftheUnbalancedinputs).
Audio outputs:
Eight Balanced Stereo Line outputsareavailablebymeansofTerminal Block
connectors.Eachoutputisusinga6-pinsTerminalBlockconnector(3-pinsforeach
LeftandRightchannel).
BesidestheLineoutputs,therearealsoconnectionsavailablefortheAmplified audio
outputsofthe(optional)POW2internalPower Amplifier Kit bymeansofTerminal
Block connectors.
Thisoptionalmodulegivestheusertheabilitytohavedirectlyamplifiedoutputswitha
powerof60 Watts(@4Ohm)foreachchannel(16 Channels - 8 Stereo outputs)or
120 Watts (@8Ohm)fortwobridgedchannels(8 Channels - 8 Mono outputs).
