2.1 subwoofer amplifier circuit.
Hello friends.circuit designing and circuit diagram creating is the most primary part of the printed circuit board. It is the very very hard working method. But in this tutorial I'm going to show you how to easily creat circuit for your own project. It is powerful 2.1 sound system at low cost.
Amplifier.
component-
Resistor- 10k ohm 1/4 watt
capacitor- 3x 2200uf 25volt,
1x 1000uf 25volt,
1x 104
3x 224
1x 10uf 63 volt
Power- 12volt 3A dc power supply
Pcb- use a good quality coper clad board
Use two jumper pin 3 and pin 13. and output of pin 13 is power 12+ and add ground to any ground channel. don't use -12 volt of the circuit. Because it is the single power circuit.
For pcb layout and circuit diagram look below.........
For cooling the power amplifier you can add cooling fan on top of heatsink.
If you want good quality sound, enhanched speaker sound and super bass so you must add a tone control unit.
Then you ready for play the 2.1 super bass amplifier like a home theater.
