Switch Mode Assisted D-Class Audio Amplifer

 The Switch Mode Assisted D-Class (SMA D-Class) audio amplifiers is a hybrid audio amplifier. It combines both a traditional linear amplifier and a switch controlled digital amplifier.

 This marriage of old and new audio principles combines the best elements of both amplifier types. At low power the linear stage produces a minimum of harmonic distortion. At higher power the digital stage ensures that power efficiency is kept high.

 Ideal for low to mid range power applications, the SMA D-Class Amp. can operate without heat sinks (since power efficiency is high) making it a perfect solution for compact applications.
