Introduction
Web Based Mini Stereo Power Amp
TheRM523andAMP523arewebbasedinputcontrolunits,allowingtheconnectionand
controlofseveralstereoaudiosourcedevices(suchasCD-player,Tuner,MP3player,
...)andamicrophone.
Theybothhave4StereoLineInputs,1StereoLineoutputand1BalancedMicrophone
InputwithPhantomPowerperformedtogetherona18-pinsterminalblockconnector.
Alineleveloutputhasbeenprovidedasalternativeoutput,tolinktheoutputsignalto
externaldevicessuchasrecordersoramplifiers.
TheRM523hasanoutputperformedwithanRJ45connector.This output is a dif-
ferentialaudiooutputwithincreasedvoltagelevel,meanttoconnecttheRM523unit
totheLX523active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interferencecaused
byexternaldevices.
TheAMP523hasanamplifiedstereospeakeroutputwithapowerof2x15Wpower.
TheamplifierconstructionisbasedonClass-Dtechnologyensuringahighefficiency
andreliability.
Theinputswitching,volumeregulationandotherfunctionscontrolcanbedoneinse-
veralways.Usingaweb-browseritcanbecontrolledfromanycomputerinthesame
