This is a simple active speaker protector circuit which has a very important use, expecially to protect the loudspeakers of a audio system. It prevent the speaker from noise sound when we turn on the power amplifier. The circuit drives the speakers after 3 to 10 seconds so that the source of the same stabilizes and stops generating cracks and noises that could damage both the speakers and the output transistors of the amplifier. This circuit powered using a 12V regulated power supply. If you have a high power audio system, you may try to build this circuit and mount the circuit in the amplifier box.
