MUSIC POWERCONCEPT
MUSIC POWER is (according tothe IECclauses n.268-3 of Jan 83) the maximal power which the amplifier is capable of producing across the
rated load resistance (regardless of nonlinearity) 1 sec after the applicationof a sinusoidal input signal of frequency 1KHz.
According to this definition our method of measurement comprises the followingsteps:
1) Set the voltage supply at the maximum operating value -10%
2) Apply a input signal in the form of a 1KHztone burst of 1 sec duration; the repetition period of the signal pulses is > 60 sec
3) The outputvoltage is measured 1 sec from thestart of the pulse
4) Increase the input voltage until the outputsignal show a THD = 10%
5) The music power is thenV
2out
/R1
,
where V
out
is the output voltage measured in the condition of point 4) and R1 is the rated load impedance
The target of this method isto avoidexcessive dissipation in the amplifier.
