I had two problems: Too much time and to few things to do. Thus I strolled the Internet and -- long story short -- started reading a master thesis on the evolution of condenser microphones. And at some point, there's been the idea that I wanted to walk Georg Neuman's road from the early 1930s. So I found myself a valve and some other small electronic parts and started soldering around.
Da ist man mal einen Moment beim Ausbauen einer Festplatte unachtsam.. schon macht es dieses Geraeusch, als wenn irgend ein billiges Plastikteil unter mechanischer Belastung splittert. Naja, wird ja auch nur so ein billiges Plastikteil vom alten Gehaeuse gewesen sein... denkt man. Aber dann schliesst man die Festplatte an, und sie meldet sich nicht mehr.
Phantom Powered Balanced Electret Microphone Preamp
So this is yet another lost and found article -- describing a schematic for a mic preamp which I really like and which I more than likely found on the Internet some 5-10 years ago. I've used this circuit a number of times as it comes in quite handy: In a nutshell, it gives you a somewhat useable phantom powered microphone at a price of EUR 10 where the XLR connector is still half of the expense. If nothing else, it's worth a shot when you just need *something*.
Phantom Powered Balanced Microphone Preamp
Some years ago I was quite active in soldering sound stuff. At some point I didn't have the necessary time any more so lots of things got forgotten. Now I found one of those little thingys and went through the process of reverse engineering to understand what I did. The pream presented on this page not equipped to be used with el-cheapo pre-polarized condenser capsules (those el-cheapo elektret thingys); it's intended to be used with dynamic or ribbon microphones.
