Hey everyone,
I just wanted to share a recent project of mine if anyone is interested in that. I've had a pair of DPA MMC 4011 capsules laying around for a while and I finally got the time to build a decent preamp for them. A year ago I bought bodies on Alibaba, that are very similar to the DPA MMP series preamps but with lesser quality internals and externals. Getting the insides out and figuring out, how I wanted to go about mounting a PCB in there was a challenge, but I came up with a 3d printed mount that mimics the original DPA mount, making ground contact to the body via a thin sheet of brass that I glued to the outside. The circuit is @rogs ' clever and straight forward OPIC, for which I designed a PCB that snugly fits the internal dimensions of the body and I'm pretty happy with how everything turned out. So a big thank you to @rogs for sharing that design!
