Class D power amplifier uses either pulse width modulation (PWM) or pulse density modulation (PDM) technology, according to technical principles. Following the digitization of the analog input signal, switch components (such MOSFETs) are controlled to restore the original signal's on-off time ratio. The output transistor can operate with ultra-high efficiency because to this special design, which virtually eliminates energy loss when it is fully on or off. The basis for high-quality music is laid by integrated amplifiers, which combine the power amplification and preamplification functions into one, improving overall performance, streamlining the user setup procedure, and drastically lowering external interference.
The Class D Professional power amplifier achieves an impressive efficiency of over 90%, significantly outperforming traditional Class AB amplifiers in energy management. This translates to 50% less energy consumption and drastically reduced heat generation, eliminating the…
