Rangkaian power amplifier dc 12v
Loudspeakers are heavy loads, and they normally require high current to be driven which is provided by an external circuit. This is because sometimes the produced sound output, let's say from a microphone or the pickup coils of the guitar, do not produce high current high amplitude output, therefore, it is not suitable to drive a loudspeaker. This is why we have something called Audio Amplifiers. There are many classes of Amplifiers and we have previously built a lot of Audio Amplifier circuits ranging from small 10W amplifiers to heavy W Power amplifier. We as well know that there are several types of amplifiers in electronics, some common names that you might have come across are Buffer Amplifier, Pre-Amplifier, and Power Amplifier. A buffer amplifier produces the same signal exactly in the same amplitude from the weak sound source, whereas the pre-amplifier amplifies the signal to a much higher voltage from the input source.
