XA series is a high performance products belong to the Class E amplifier , And its circuit have tested for times. Class E amplifier technology to overcome the problems like: Power not strong for Class AB and Overheat of Class H. It realizes the collation and recording of Class D amplifiers without any loss of the sound quality of Class AB amplifiers. Also the class E technology solved the problems as : weight, dimensions, overheat of High-power amplifier. Class E technology uses the smallest performance to output the large signal, which greatly improves the efficiency of power amplifier.

It use the class D amplifier working modes to provides a Class AB effect at the output end. And almost all the energy working on the output end, only a few of energy dissipated from the heat sink.

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 into a pulse width modulated signal. In addition, Class E amplifier specifically design for the Low heat working condition, The XA series amplifier comes with Class AB sound quality and Class D efficiency. With 2U design and different kinds of customization amplifier to make the XA series amplifier suitable for many occasions as: Disco, Night club, Karaoke etc.... It's a good product within a rare quality in Sound engineering.
