Many electronics circuits and projects for learning in simple ways.

Audio loudness control

If your main amplifiers. But the sound is not clear as low treble and little bass. We offer an easy way. Using less equipment. You create a very simple

Audio loudness control circuit used to add bass. More during the normal listening levels.
It is a passive circuit and does not use the power supply.

When the input signal into. Switch S1 is an option to use open (ON) using loudness control. Off (OFF) to use a bypass. When the switch S1 to the ON position the signal will flow through C1(0.001uF), C2(0.01uF) and R1(2K). This will serve as a low pass filter circuit.VR1 is adjusted by the strength of the signal to the output.VR1-100K Linear Potentiometer, which uses the volume type with a central bar (Center Tap) only. The output of the circuit will be connected to the region to pre-tone next step.

Note: All capacitors use Ceramic Capacitor or Mylar Capacitor them low cost

How to build
This circuit has a few components so you can builds easily as Figure 2 make PCB layout and putting all components on PCB and connecting to your audio system.
