semua power amp ya gitu mas..
mau QSC, Crown, Labgruppen, Yamaha, power consumption pasti dibawah rating maximal (biasanya bridge 4 ohm, atau stereo 2 ohm). kenapa?
karena power consumption (dalam ampere atau watt) diukur dengan pink noise, bukan gelombang sinus murni 1 khz, dengan level 1/8 dari daya full power 1 khz.
pink noise 1/8 daya merepresentasikan program music yang mendekati clipping dan digunakan sebagai patokan maksimum limit mengoperasikan power amp
cuplikan dari table power consumption QSC:
Current draw at 1/8 of full power is measured with pink noise as a signal. It approximates operating with music or voice with light clipping and repesents the amplifier's typical "clean" maximum level, without audible clipping. Use these figures for typical maximum level operation.
