(1)Sine wave 1kHz
(2)Pink noise acc. to EN60065
(3)1BTU = 1055.06J = 1055.06Ws
(4)10% mains over voltage
(5)PD = Power dissipation
The following factors allow direct proportional calculation of the mains current (Imains) for different mains
supply voltages: 100V = 2,3; 120V = 1,9; 220V = 1,05; 240V = 0,96
For power amp models with integrated transformers, the listed values for the 100V outputs are equally
applicable for the 70V, 50V and for the low-impedance outputs as long as the connected load is
equivalent as well.
