XA series is a high performance products belong to the Class AB amplifier , And its circuit have been tested for long time. It's own amplifier technology solves problems like these: power not strong enough of other clalss AB and overheat of Class H. It realizes the collation and recording of Class D amplifiers and without any loss of the sound quality of Class AB amplifiers. Also it's new class AB technology solved the problems as : weight, dimensions, overheat of High-power amplifier. It uses the smallest performance to output the large signal, which greatly improves the efficiency of power amplifier.
It use improved technology like class D amplifier working modes to provides a Class AB efficiency at the output end. And almost all the energy working on the output end, only a few of energy is lost in heat dissipation. The output signal with an extraordinary sound quality when the signal working on the output by Class AB working modes.  From the input end to the output the signal still keep a analog state without converting in	o digital signal.
In addition, it specifically design for the Low heat working condition, and come with good sound quality and high efficiency. It is suitable for many applications: disco, night club, karaoke etc.....
