0-12V 3 Band Stereo Tone Control

Lets Build This Tone Control

Hello Friends, in this post I make a tone control for Single power supply amplifier. You can power up this tone control by only 0-12V power supply. For this tone control I have used NE5532 IC. But in place of NE5532 IC, you can also use TL072 or 4558D IC. In this tone control, you can control the High, Mid and Low frequency. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to for manufacturing my PCB. PCBWay are the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil and PCB Assembly Service. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hour. And they distribute, worldwide. The more you order, the less price you have to pay.

You just need to upload the Gerber File, and select the quantity, color, silkscreen, thickness etc. Then select your country, and shipping method and then Pay. PCBWay ( will deliver your PCB within 7-10 days.

After one week I received my PCB. You can see the PCB quality, it's awesome. I have ordered Red PCB. But you can choose your PCB color. PCBWay provides a total of 9 color solder mask - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black, and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. And maximum Layer is up to 14 Layers. And If you order PCB the first time at PCBWay, then you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.

Testing Method After Complete This Tone Control

Check Voltages:- Check all Audio Output and Audio Input voltage. Here you get no voltages 0.00V. If you get same voltages, then connect this preamplifier to amplifier.

Power Supply:- Recommended Transformer 0-12V 750mA to 1A, or 12V Battery.

  1. Thanks to their great flexibility, absolutely automatic robot techniques for laser welding are a perfect selection for an extremely big selection of applications. As nicely as being some of the cost-effective methods of sheet metal fabrication, the technique of bending metal is also be|can be} extremely versatile. Anything from small fixings such as brackets, to a lot larger precision machining pieces such as transport containers could be created by bending methods. Most sheet metal fabrication involves forming the metal in a method or another. The strategy of forming metal involves fashioning metal parts and objects by way of mechanical deformation.
