This is an amplifier circuit diagram using SVI3101. this is a stereo audio board. we can get 50w+50w using Ac 24-0-24 voltage. this IC we can get from an old audio 3 disk CD player.

This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
