According to this definition our method of measurement comprises the following steps: 1) Set the voltage supply at the maximum operating value -10% 2) Apply a input signal in the form of a 1KHz tone burst of 1 sec duration; the repetition period of the signal pulses is > 60 sec 3) The output voltage is measured 1 sec from the start of the pulse 4) Increase the input voltage until the output signal show a THD = 10% 5) The music power is then V 2 out/R1, where Vout is the output voltage measured in the condition of point 4) and R1 is the rated load impedance The target of this method is to avoid excessive dissipation in the amplifier.
