Electronics Help Care electronics circuit diagram Stereo audio amplifier:
This is the Stereo audio amplifier circuit. This circuit can make 30+30 watts using 12 volts. We can also use a 12-volt battery. Stereo audio circuit diagram with bass tone control.
TDA7297
Subwoofer amplifier circuit board:
This is a subwoofer amplifier circuit board. This diagram makes only bass for the amplifier. It’s a pre-amplifier diagram. This diagram runs on 12 volts. only positive and negative voltage. It’s a mono diagram. It has two adjustable volumes. One is the volume, another is the bass frequency. mono audio input and mono audio output.
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problem, then this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line then this circuit protects that voltage. This circuit should not allow any direct voltage to be sent to the speaker. This circuit is very important for protecting the speaker.
