Description

Microphone Preamp and Processor

I designed this to be a cheap version of the dbx 286s Mic Preamp and Processor. It doesn't all work but the preamp and filters are good. The noise gate needs work. I used the preamp and filter in a project (video below). Maybe you can use the preamp. maybe you can improve the design. There were a couple problems with the Rev A layout but Rev B are the files included here. They fix the problems but were never actually built. The preamp chip used is very good. Below are some videos (there are more on my channel).
