Speaker protection circuit diagram for amplifier:
This is the speaker protection circuit diagram for the amplifier. Every amplifier needs this circuit to protect the speaker. When the amplifier makes a problem, then the voltage comes out from the speaker line. And the voltage burns the speaker. For this, we need this circuit to protect the speaker. This circuit needs a 12-0-12 voltage to run.
This is the Speaker protection circuit diagram. It can protect our Speaker from burns. 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.
Subwoofer amplifier using TDA2030:
This is a Subwoofer amplifier using the TDA2030 IC. This circuit can make 15+30+15 watts of output. It needs 12-0-12 voltage and 3 amperes. The input is 2.0, and the output is 2.1. Left speaker, Right speaker, and the subwoofer speaker output. Here has 3 adjustable volumes. 1st one for the master vol. 2nd one for the surround speaker, and 3rd one for the subwoofer. Normally, it’s used in a 2.1 sound system.
