Features:

 Class D power amplifier circuit achieves a working efficiency of up to 90% and the sound quality of a Class A power amplifier while saving power.

 The output power of a regulated switching power supply is constant and will not decrease due to a decrease in voltage.

 Intelligent power limiting function can set the most matching output power according to the impedance and power requirements of the speaker.

 The compression limit function can be selected. According to the requirements, the power amplifier output will not clip in the case of overload.

 Full-featured protection: soft start at power on, overload, overheating, short circuit, DC output, peak voltage limit, intelligent peak clipping protection, and output zero current switch.
