Low-Cost 5.1 Power Amplifier

Low Cost 5.1 Amplifier with Gainclone IC

On this occasion, I want to make a cheap version of the 5.1 Amplifier for home theater. This 5.1 amplifier is included with the processor, and the final amplifier used is the LM1876 gainclone IC this designed 5.1 amp with an analog system, which uses an op-amp as a stereo signal breaker to 5.1 in the front amplifier, so don't think this is a digital system, because this tool is used to divide the stereo analog signal into 5.1 and then amplified by the LM1876 power amplifier. Here's a 5.1 power amplifier scheme with a low-cost budget:

The following is the appearance of the low cost 5.1 amplifier PCB Layout design:

PCB Layout 5.1 Amplifier Low Cost

You can download the PCB layout design at the end of the post, then it's time to order pcb on PCBWay.com, you can download the Gerber file at the end of the post to place an order on PCBWay.

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

The following is an example of a PCB printed on PCBWay, I purposely printed it in black to make it look luxurious.

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

After all the components are available, the next step is to apply tin paste to the PCB with the help of an SMD stencil

Then we put the smd component first.

After that soldering stage, solder using a solder blower to make it easier.

The 5.1 low-cost home theater amplifier kit has been completed and it's just a test. It's tiny and doesn't take up much space.
