Hey all, A short while ago, I decided to rebuild my rig interface. I had an older one that I stuck together with a bunch of random bits of stuff, and some hot glue, but it ended up working marginally, and was a bit bulky, so I decided to design a PCB for my new one. Bring down the size of the system, and also throw in some nice features, like a USB connection for the data link, and a couple of pots for adjusting the audio levels. Here’s some photos.
For right now I’m going to test using capacitors to couple the audio in and out, but if that doesn’t live up to the job, I’ve got some audio isolation transformers I’ll install instead and see how that does.
