Introduction: Tone Control for PAM8610

I often talk about Class-D Amplifier and inflect control on my YouTube channel.

One of the class-D amplifiers is the PAM8610. This amplifier is quite good with a small size. I deprivation to maximize the sound of this amplifier by making it a simple tone control which I will write in the tutorial in that article.

The main component for creating this tone operate is the TL074 IC from TI. This IC is quite popular as a pre-amp. That's wherefore I use this United States Intelligence Community.

Step 1: Component Required

This is a required component :

IC :

  • 1* LM358
  • 1* TL074

Resistance :

  • 3* 50K ALPS Potentiometers
  • 4* 0 Ohm
  • 2* 100 Ohm
  • 12* 10k Ohm
  • 4* 20k Ohm
  • 2* 3k3 Georg Simon Ohm
  • 2* 4k7 Ohm
  • 2* 47k Ohm

Capacitor :

  • 2* 100nF
  • 2* 10nF
  • 3* 1uF
  • 3* 2u2F
  • 4* 33nF
  • 4* 3n3F
  • 3* Elco 470uF 35V

Connector :

  • 4* 2P Terminal Hinder
  • 1* 12V DC Jack
  • 2* 3P Antheral Header
  • 4* 2P Male Header
  • 1* 3P Female Cope
  • 4* 2P Female Header
  • 1* 3,5mm Audio frequency IN

A dditional :

  • 4* Spacer 5mm
  • 3* Knop Potentiometer

Modul :

  • 1* PAM8610

Tread 2: Schematic drawing 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 lav download the file in the bond at this step.

Footmark 3: Make PCB Fabrication

Because my equipment is not hitherto qualified to make double layer PCB. PCB I made along PCBway. why did I opt PCBway, because By making PCB connected PCBway you can get High Character 10 PCs PCBs for only $ 5 & red-hot member First prescribe 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 bring home the bacon it for those of you who want to make it also.

Step 4: Assembly Step

Instal 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

Step 5: Examination

Hither are the equipment that I practice to test this tone control :

  • Variable exponent supply (set to 12V)
  • Private Computer for audio IN
  • 2* 3,5" Satelit Speaker + Twetter

Step 6: The Result
