Mono Channel DSP power amplifier module 800W

Mono Channel digital amplifier Class D HIFI Power amp module

The operation of the Digital Amplifier Module is highly sophisticated. First, upon receiving an analog audio signal, the module rapidly converts it into a digital signal through an Analog-to-Digital Converter (ADC). These digital signals then undergo a series of meticulous processes in the Digital Signal Processor (DSP), such as filtering, equalization, and reverb, to optimize the sound quality. Subsequently, the processed digital signals are converted back into analog signals by a Digital-to-Analog Converter (DAC), and finally, power-amplified by the output stage amplifier to drive the speaker to produce sound. For instance, in a common Class-D amplifier, the power output transistors operate in a switching state, controlling the power output by adjusting the duty cycle of a fixed-frequency rectangular pulse, which significantly improves efficiency.
