They operate by rapidly switching back and forth between the supply rails, being fed by a modulator using pulse width, pulse density, or related techniques to encode the audio input into a pulse train. Now you know why the makers of expensive high-end amplifiers only use AB technology. Thanks A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices operate as electronic switches, and not as linear gain devices as in other amplifiers. Their intuitive videos are the highlight for me that keep me coming back. Its rated output power is 250Wpc into 8 ohms and 500Wpc into 4 ohms, and e1X is reportedly stable into 2 ohms.
