Self built audio compressor

Drip opto V3
This is a Universal Audio LA-2A clone, which PCB was designed by drip electronics for DIY purposes. It takes about 1 day to assemble all components, but which are sometimes really tricky to get. So it took about 1 week to get all parts until finishing “bugfixing”. I tried it now on vocals and acoustic guitars and it sounds GREAT. Can’t wait for the next mix…. but before I have to do some “clean-up” inside the case.

    beautiful work. looking to start in on one myself. did you use the 3RU case he recommends? any advice regarding the front panel?

    Thank you!
    I think drip recommends a case “in-one-piece”. My case is made of 6 parts (each side) and is not the highest quality. But I have nearly no noise in the soundpath and the compressor stays in the studio, so I have no need for a better case.
    I bought this case from the admin of or have a look at: there you’ll find lots of other amazing projects, and help on parts.

    Hi mate.

    Seems like I need special sized parts to fit this PCB?
    Where to get parts?

    Hi ILya.

    There is a detailed list for the parts in the manual which you get from drip’s website (including order codes for mouser).
    For more info the best way is to go to http://www.prodigy-pro.com/diy/
    There you find lots of stuff for troubleshooting and various questions regarding this project. Just search the forum for Drip LA-2A Ver.xxx

    *thumbsup*
