    Classification of power amplifiers and the working principle of class D power amplifiers
    First you need understand what is a power amplifier? Explain that the power is amplified, not the current or the voltage, right? How it works: The power of the power supply is converted into a current that changes according to the input signal through the current control of the transistor, and the current of the collector is always the amplification of the base current,...

    How should the power of the amplifier and the speaker match?
    When installing a sound system, it is inevitable to encounter the problem of the connection between the amplifier and the speaker. In terms of sound, we will pay attention to whether it is suitable for warm and cold, moderate soft and hard, and finally make the whole set of equipment return to neutral tone. This is only from an artistic perspective. From the technical...
