Hello guys, in this post I make a 4 channel audio line distributor. This audio distributor have 2 channel input and 4 channel output. You can control up to 4 amplifier using this audio distributor. For this audio distributor I use 4558D IC, but in place of 4558D IC you can also use TL072 or NE5532 IC. These IC are dual channel OP-AMP IC, so I use here 2 IC and I get 4 channel output. For designing my PCB, I used EasyEda online software. Then I export the Gerber file (which you can download). And then I go to PCBWay 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 hours. 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 Yellow PCB. But you can choose your PCB color. PCBWay provides a total of 9 color solder masks - 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 the 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.
