4 Channel audio amplifier circuit

4 Channel audio amplifier circuit

This is a 4-channel audio amplifier circuit diagram. It has 4 audio inputs and 4 audio outputs. The output watts per channel are 50 watts. This diagram needs dual power: positive low voltage, positive high voltage, negative low voltage, negative high voltage, and ground voltage. 70-35-0-35-70 voltage is needed for this IC. The output watts will be 50 watts.

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.
