A digital amplifier’s operation is a little like the way a CD or digital recorder works with PCM (Pulse Code Modulation), the basis of all digital audio-recorded media. In PCM digital recording (a CD, for instance), the digital sampling ADC (analog-to-digital converter) “describes” the incoming analog voltage and frequency with a digital code of ones and zeroes.

It applies a varying resistance to the output circuit to re-create the voltage fluctuations of the original audio signal. In most amplifiers, this load is too much work for the original audio signal. For this reason, the signal is first boosted by a pre-amplifier, which sends a stronger output signal to the power amplifier. The pre-amplifier works the same basic way as the amplifier: The input …

Just as analog audio is defined by the values of frequency and amplitude, digital audio has two main two parameters: sample rate and bit depth. Sample rate is how many times per second the sound is sampled, and bit depth is the amount of dynamic range each sample is capable of capturing.

Analog-controlled class D. Switching amplifiers with an analog input signal and an analog control system. Normally some degree of feedback error correction is present. Digitally controlled class D. Amplifiers with a digitally generated control that switches a power stage. No error control is present.

A CD player converts a set of digital instructions into a regulated energy flow. Likewise, a phonograph converts a set of molded plastic instructions into an energy flow. The preamplifier converts the flow into a form that the power amplifier can use. The power amplifier converts the flow into a form the speakers can use.
