2.3.7GateCH1-CH2
Thisfunctionallowstomutetheamplifierchannelsindividuallyifinputsignalamplitudeisfallingbelowthevaluesshownin
thefollowingtable. Youcanenable/disableitbypushingtheon/offbutton.Gatingtheoutputisdelayedby5secondsafter
inputsignalremoval,andfollowsinreversedwaythebottomgreenLEDontheCH1,CH2barLEDdisplay*(mutedifgreen
LEDisoff).
2.3.12Barmeters
IntheBarmetersscreenyoucanchooseiftheLEDbarsoperateasoutputvoltagemeterandLCDbarinthemainscreen
asoutputcurrentmeter(byselecting"LEDVolt,LCDCurr),orviceversa(byselectingtheotheritem).
2.3.13Outputmeters
IntheOutputmetersscreenyoucanviewthevaluesoftheoutputsignalforCH1andCH2.Furthermore,theimpedanceof
theloadisshowedinthebottomlineofthescreen(seefigure2.3.9).Minimumofoutputvoltageforimpedance
measurementsis10Vrms,measurementsvaluesarestoredintologbook. Timebetweensingleimpedancemeasurements
canbeuptoseveralminutesdependingonprogramsignal.Outputpowerisshownasmaximumvalueevery200mS.

2.3.9IdleMode
Theidlemodefunctionisapowersavingfeature.Byactivatingit,iftheamplifierdoesn'tdetectthesignalfortheuser
definedamountoftime,theoutputstageisturnedoff,savingabout40Wofpowerperchannel. Thismeansreduced
heating,longeramplifierandfanslife,and,especiallyforfixedinstallationpermanentlyturnedon,alowerelectricitybill.
