TheLEDbarscanfunctionasoutputvoltageoroutputcurrentmeters;inthefirstcasetheLCDmetersfunctionas
outputcurrentmeter,viceversainthesecondcase.
TheLEDbarshavediagnosticfunctionalso;aflashingyellowLEDindicatesacriticrangeoftemperature(from80°C
to85°C)ofthepowerdevicesonthecorrespondingchannel,ifthisLEDislightingconstantly,thetemperatureisabove
85°C. A lightingconstantlyredLEDindicatesthatthecorrespondingchannelisunderprotectionandinthiscasethe
writing"PROT"appearsinthefirstlineofthedisplay.
ThefirstgreenLEDatthebottomsideoftheLEDbarindicates,
whenlighted,thepresenceofinputaudiosignalabove-60dBVonthecorrespondingchannel;the2nd,3rdand4th
LEDintheascendingorderindicatesanoutputlevelof-3dB,-6dBand-10dBrispectively. ThegreenLEDswillbe
lightedduringnormalworking. TheyellowLEDwilllightat-1dB.Iftheleveloftheaudiosignalreachthechannel
