Left and right outputs and subwoofer outputs. Surround channels got 15+15 watts outputs. The subwoofer output is 30 watts. 12-0-12 voltage is needed to run this circuit.
Here use TDA2030 Ic. The subwoofer is in bridge mode using two TDA2030 ICs. This IC needs a high-quality heatsink. Each IC needs a separator.
This is a Stereo passive tone control circuit for the amplifier. This circuit does not need any voltage to run because it has no pre-amplifier. This circuit has 3 adjustable volumes. One is the main volume for the bass and the treble. It’s a stereo Bass tone controller. This circuit has stereo audio input and stereo audio output.
