DIY bass treble volume homemade

In the following tutorial, I am showing how to make homemade extremely powerful heavy DIY bass treble volume controllers for DIY amplifiers. This is a general purpose tone control which will work with maximum power amplifiers to control low pass and high frequencies. This tone control is designed with minimum components. All the components are easily available on any electronic parts shop. Or you can remove them from most of the scrap circuit boards or elsewhere.

Circuit diagram

Following is the circuit diagram of DIY bass treble volume controllers.

Stick 3 nos. of 50k potentiometers on a piece of small sheet. Now take one piece of 1k resistors. Solder its one leg to Pin.1 of volume control and the other leg solder to Pin.2 of bass controller. Now take one piece of 2.2k resister. Solder its one leg to pin-3 of volume control and the other leg to pin-2 of bass controller.

Take 2 nos of 104 ceramic capacitors. You can use here 100nf or 104J capacitor as well. Solder one of them to pin.1 and pin.2. And the other one to pin.2 & pin.3 of bass controller.

Solder one leg of third 104 ceramic capacitor to pin.1 of bass controller. And the other leg to pin.1 of treble controller. Now we will connect the fourth and last 104 ceramic capacitor. Solder its one leg to pin.3 of volume controller and the other leg to pin.3 of treble controller.

Take small piece of connection wire and solder its one end to pin.1 of volume controller and the other end to pin.2 of treble controller. Likewise we have completed the entire internal connectivity of tone control circuit.

The final result of this tone control project will look like the following image. In next step I will show you how to connect the input connections of 3.5mm mobile audio jack. And also will show the connections of output of this tone control to in input of power amplifier.

External connections:

Now use a 3.5mm audio jack to provide audio signal to amplifier through this bass treble kit. Connect the grounded brown wire of 3.5mm audio jack to pin.3 of volume control and rest the two wires of left & right channels output to pin.3 of bass controller, as shown in the following image.

Now its time to connect this tone control with the power amplifier. We will take out two more connections from this kit for amplifier. Take two pieces of connection wire. I took blue and black for this purpose. Solder one end of blue wire to pin.2 of volume controller. And solder the other black wire to pin.1 of volume control for ground. You can watch video in the very beginning of this post for more clarification where each and every step is shown visually.
