Speaker Protection circuit diagram:
This is a Speaker Protection circuit diagram. every amplifier needs this circuit. when the amplifier got any problem then this circuit disconnects the speaker. when the IC or transistor got a short circuit, then the voltage comes out from the audio output. to protect the speaker we need this circuit. if the voltage goes to the speaker, then the speaker will burn. this circuit runs with 12-0-12 voltage.
every amplifier needs this circuit
