Attherearsideofthedeviceareallaudioin-andoutputsprovided.
Thevariousavailableinputsare4unbalancedline-levelinputsandonebalanced
microphoneinput(withphantompowerpossibility).Thoseinputsareallperformed
withan18-pinEuro-Terminalblockconnection(togetherwiththeline-level
audiooutput).AudiosourcessuchasCD-players,Tuners,MP3players,...canbe
connectedtotheline-levelinputs,whilemicrophonescanbeconnectedtothe
microphoneinput.Whenusingcondensermicrophones,thephantompowerpossibility
shouldbeenabled.
Therearetwodifferentkindsofaudiooutputsprovided,bothofthemcarryingthe
sameaudiosignalwithdifferentvoltagelevels.
TheaudiooutputperformedontheEuro-Terminalconnectionblockisastandard
line-levelaudiooutputwherebytheRM523canbeconnectedtoanyaudiodevice
withaline-levelinputsuchasanamplifier,pre-amplifier,activespeakersystem,...
ThesecondoutputisperformedwithanRJ45andisadifferentialaudiooutputwith
increasedvoltagelevel,meanttoconnecttheRM523unittotheLX523speaker
system.Becauseofthedifferentialsignalandincreasedvoltagelevel,themaximum
cabledistancecanreachacablelengthupto500metersoverCAT5cablingand
makesthesignalinsensitivefornoiseandinterferrencecausedbyexternaldevices.
