Tone Control for PAM8610
I often talk about Class-D Amplifier and tone control on my YouTube channel.
One of the class-D amplifiers is the PAM8610. This amplifier is quite good with a small size. I want to maximize the sound of this amplifier by making it a simple tone control which I will write in the tutorial in this article.
The main component for creating this tone control is the TL074 IC from TI. This IC is quite popular as a pre-amp. That's why I use this IC.
Component Required
This is a required component :
IC :
Resistor :
Capacitor :
Connector :
- 4* 2P Terminal Block
- 1* 12V DC Jack
- 2* 3P Male Header
- 4* 2P Male Header
- 1* 3P Female Header
- 4* 2P Female Header
- 1* 3,5mm Audio IN
Additional :
- 4* Spacer 5mm
- 3* Knop Potentiometer
Modul :
- 1* PAM8610
Schematic and Layout
Schematics and layouts were created using the Eagle 9.6.2 application. I've provided you with the original eagle file and the PDF files for the schematic and layout. You can download the file in the attachment at this step.
Make PCB Fabrication
Because my equipment is not yet qualified to make double layer PCB. PCB I made on PCBway. why did I choose PCBway, because By making PCB on PCBway you can get High Quality 10 PCs PCBs for only $ 5 & new member First order Free: www.pcbway.com .
For the finished PCB, you can see in the picture above. To print on PCBway, PCB design needs to be converted into gerber format. You can download the gerber file below, I provide it for those of you who want to make it too.

Assembly Step
Install all components according to the values in the schematic.
For the process and the results of this stage can be seen in the image above
Testing
Here are the equipment that I use to test this tone control :
- Variable power supply (set to 12V)
- Personal Computer for audio IN
- 2* 3,5" Satelit Speaker + Twetter
The Result
