The 250ASP combines a highly efficient and powerful switch mode power supply with an audiophile 250 W class D amplifier. The amplifier section is essentially the same as the 250A module. The power supply of the 250ASP includes a DC hanger bus output, which can be used for powering additional 250A modules. This makes it very convenient to create 2 and 3 channel amplifiers, combining the 250ASP with the 250A.
