(power level control) function able control maximum index modulation setting value external resistance voluntarily, prevent signal from becoming over modulation mode. addition, this circuit output power limit circuit because function maximum index modulation voluntarily, variable from with output power linearly state that made power supply voltage load resistance fixation. Because function suitable rated output with same power supply voltage/speaker regardless screen size flat screen televisions this, plan commonization board. Furthermore, function reduce abnormal noise hard clip that output wave pattern becomes soft clip when limited output power.
