It’s an “ANALOG” amplifier
“The myth that a “CLASS D” is a DIGITAL AMPLIFIER is incorrect. SPEC CORP. has adopted “Pulse Width Modulation” in our “CLASS D”. This “PWM” converts “signal amplitude” to “duration switching” through “ANALOG PROCESSING”. This system doesn’t digitize the audio signal. This is in fact type of analog amplifier because magnitude resolution is infinite. “CLASS D” with PWM contributes to bring you beautiful acoustical sound. In the past, some audio makers adopted delta sigma modulation for “CLASS D” . This is quite simply “1bit digital” modulation. Combination of switching technology and analog technology makes the sound realistic and beautiful.”
