he purpose of such a device is to boost the level of the sound signal it receives from the input so that it can be played louder through the speakers. Whether you have a car audio station, a home audio station, or a professional audio station, they will all generate a stronger signal and high-quality sound.
After absorbing the weaker input signal from musical instruments, a laptop, or another source, the output circuit regulates and releases the energy held in capacitors and the transformer, amplifying the signal to be played by linked speakers.
