Note (*):
MUSIC POWER CONCEPT
MUSIC POWER is the maximal power which the amplifier is capableof producing across the rated load resistance (regardless of nonlinearity)
1 sec afterthe application ofa sinusoidal input signal of frequency 1KHz.
Note (**):
Tested with optimized Application Board (see fig.2)
Note (***):
Limited by the max. allowable current.
