Introduction
Powersoftisaleadingcompanyinthefieldofhighefficiencyaudiopowermanagement. ThetotallynewPowersoft's
DIGAM(DIGital AMplifier)technologyhaschangedthewaytheworldlooksatprofessionalaudioamplification.No
otheramplifierscomecloseforapplicationsdemandinghighpowerandlongtermreliability. Thankstoamazing
reductionsinheatoutputalongwithreductionsinweightandthespecifichighoutputpower,DIGAMamplifierscanbe
usedinanunlimitedrangeofapplicationssuchasconcerttouring,operahouses,theatres,churches,cinema,theme
parks,televisionsoundstagesandindustrialapplications.
Moresoundandlessweight
TotallyDigitalwithHighReliability
Comparedtoaconventionalamplifier,PowersoftDIGAMtechnologyoffersveryhighefficiencyanddeliversmore
powertotheloudspeakerswithmuchreducedheatdissipation. Thisgreaterefficiencyenablesdimensions,weightand
powerconsumptiontobereduced. Theoutputstagesoftheamplifierstypicallyrunat95%efficiency,dissipatingonly
5%oftheinputenergyasheat.
OneofthemostinterestingcharacteristicsisthatDIGAM'sefficiencyisalmostindependentofoutputlevel.
Conventionalamplifiersachievetheirbestefficiencyonlyatfullratedpoweroutput.Sincestandardmusichasan
averagepowerdensityof40%ofthemaximumlevel,conventionalamplifierscaneasilygenerate10timesmoreheat
thanDIGAMforthesamevolumeofsound.
Crystal-clearhighs,andatight,well-definedlowend:themostaccuratereproductionofanaudiosignal.Patented
designfeaturesensureveryhighperformanceinparameterssuchasdistortion,frequencyresponse,slewrate,power
bandwidthanddumpingfactor.
TheDIGAMseriesisbasedonPWMtechnologythathasbeenusedfor30yearsormoreinpowersuppliesand
inverters.PWMprovideshighreliability,smallsize,lowweightandhighefficiency. A PWMconverterworksasahigh
frequencysampler,convertingthevariableamplitude(audio)signalintoanimpulsesequencewithaveragevalue
equaltotheaudioinput.
DIGAMamplifiersuseveryhighsamplingfrequenciestoobtainhighperformancesacrosstheaudioband.Powersoft
holdsseveralpatentsontheDIGAMtechnology.
PowersoftisthefirstamplifiermanufactorthatadoptPowerFactorCorrection. Thisuniquefeatureensuresthata
predominantlyresistiveloadispresentedtomains,minimizingcurrentdistortionandvoltage/currentdisplacement
Thisleadstomuchimprovedperformanceoftheamplifierathighlevelsofoutputandavoidsmains-voltagecollapses,
typicalofstandardandswitchingpowersupplies. Anothergreatadvantageofthistechnologyisthatitsperformanceis,
toalargeextent,independentofmainsvoltage. Theratedoutputpowerdoesnotvarywithload/lineconditions.
