Subwoofer Amplifier Schematic. In the above tda2030 circuit diagram the connection of r1 and c2 can be done in series. The subwoofer amplifier circuit is simple.
But a lower impedance also means more stress on the amp. The r4 resistor which is connected in between pins 2 4 is known as a feedback resistor. The audio signal is filtered by the sallen key low pass filter using the opamp such that only frequencies below and equal to 200hz are passed and remaining filtered.
We design a circuit with tda2030a as a driver to power transistor output to apply output up to 30 watts.
Audio signal is initially filtered in order to eliminate the high frequency content and enable just the lower frequencies to cross via it. If this resistor is not proper then this circuit will not work properly.
