Simple Bass Booster for your audio amplifier

Bass Booster Amplifier

This circuit is a bass booster. This device can be used on amplifiers or active speakers that you feel lack bass.

Its use is very easy, namely by connecting the bass booster input to a music source and connecting the output to your amplifier or active speaker input that feels less bass and then connecting the voltage source to a 12V-0-12V transformer which is about 0.5-1A.

However, it should also be noted that the speakers and amps used must be able to produce the bass produced by this bass booster.

Here's a design layout designed by Barlex Respectaizer:

After the design feels good, the next step is I will print the PCB on PCBWay.com

By the way, PCBWay provides New Soldermask Colors - Pink, Gray, Orange, and Transparent.

Each additional choice in PCB manufacturing, means adding more customization for those of you who want to make PCBs on PCBWay, this is very important to interpret your project perfectly, especially for electronics enthusiasts and creative makers who like to show individuality. 

PCBWay offers you the most options for creating unique products, such as color and material customization.

The new solder mask colors include PINK, ORANGE, GRAY, and even TRANSPARENT. What’s more, to meet some clients’ needs, we also release the “Black Core PCB” materials, so you can use them for your specific requirement. Now you can check all the available solder mask colors at the "Advanced PCB" online quote page, and we're excited to see your new boards with these new glamorous colors!

New Soldermask PCBWay

Here is the PCB printed in PCBWAY, the PCB is printed in red silkscreen color.

The next step is to prepare the required components, namely:

After all the required components are available, the next step is to insert the components into the PCB one by one.

The next step is to solder the component legs with solder at the bottom of the PCB.

This bass booster kit has been completed and just a test.

Next, I tested this bass booster by connecting a 12V-0-12V transformer, then input the bass booster to a music source and the output to the LM1875 stereo amp input that lacked bass to see if it was working. And the results are really satisfying!

The bass can be boosted very strongly without reducing the clarity of the sound, provided it does not exceed the capabilities of the speakers or amps that you will use.
