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 are 3 adjustable volumes. 1st one for the master, 2nd one for the surround speaker, and 3rd one for the subwoofer. Normally, it’s used in a 2.1 sound system.
TDA2050 MONO BRIDGE:
This is the TDA2050 MONO BRIDGE amplifier circuit diagram. This is a mono amplifier circuit diagram. Here we can use 12 12-volt to 24-volt. This circuit can make 32 watts of output. here used TDA2050 IC. We can also use the TDA2030 IC. Here needs a single voltage is needed.
This is the Speaker protection circuit diagram. It can protect our Speaker from the 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.
How to make an amplifier 4.1 amplifier. This diagram we can use as a car amplifier, or we can also use it in the home, this is home theater amplifier also. here in this circuit diagram can make 200 watts. par speaker 50 watts. 50+50+50+50=200 watts. TDA7388 Ic number. normally this is used in the car audio player. In this circuit diagram, we can use 4 inputs and 4 outputs.
