The “Power Engine” is a low-power switching power supply (SMPS) for low voltages on the amp board. The large linear power supply provides high voltages for the Class-D power stage. According to the manufacturer, they have made a breakthrough in SMPS design that can rival linear power supplies. This “Power Engine” is the first use of such a design for AMG STA-SE.
