I measured one of the Karan POWERa Mono amplifiers that JVS auditioned, ... The Karan's maximum power into 4 ohms is specified as 3.6kW (32.55dBW). I measured 2.5kW into 4 ohms at 1% THD+N (fig.5, 31.0dBW). Again, the wall voltage had dropped by several volts at the clipping power (footnote 1). station edgeWeb7 nov. 2024 · Best answer The THD can only be calculated correctly if the correct base frequency is specified. For the first plot in your example, this is obviously not the case (you specified half the base frequency). The DC component is not taken into account for calculation of the THD.
