Note (*):
MUSIC POWER CONCEPT
MUSIC POWER is the maximal powerwhich the amplifier is capableof producing across the rated load resistance (regardless ofnon linearity)
1 sec after the application of a sinusoidal input signal of frequency 1KHz.
Note (**):
Tested with optimized Application Board (see fig. 2)
Note (***):
Limitedby the max. allowable current.
