The Speaker Protection Circuit has two main functions: to protect the audio amplifier and the loudspeakers during start-up sequence when the amplifier output might exhibit DC voltage, and to protect the loudspeakers in the unlikely event of an amplifier power stage failure, where DC component would damage the speaker voice coil.Important Note:- The ground of the amplifier should be connected at the Speaker Protection Circuit GND
