Pulse width modulation (PWM) or pulse density modulation (PDM) technology is used by Class D Amplifier Board. After converting the analog input signal to digital form, the switching elements (often MOSFETs) are controlled to restore the original signal's on-off time ratio. Because there is minimal energy loss while the output transistor is in the completely on or totally off state, this method enables the Amplifier circuit board to function with extremely high efficiency. The audio amplifier module combines the capabilities of Power Amplifiers and pre-amplifiers into a single unit. This architecture improves overall performance and streamlines the user setup procedure, particularly when it comes to lowering outside interference.
