Here's a link to a german site, i think you will understand the PDF even if the text is in german. http://www.sengpielaudio.com/Anschluss- ... ofonen.pdfIf your 421 were the "hi" version with the high output impedance then there would be a small transformer inside, which is not too complicated to ta...

A guitar split in two amps and a mic on each speaker is pretty regular here. When i have the guitar player plug/unplug his guitar to get a short signal i can see on the DAW which mic needs to go closer or further to it's speaker. I often noticed that just having both capsules the exact same distance...

As a quick sidestep to the discussion i wanted to add something about cars in general. A friend of mine is a engineer and inventor with some patents to his belt, he won a inventors competition (2nd) and then got to hang around with the r+d top hats from two motor companies. The lowdown is, they went...

I found two more M380-compatible capsules in my workshop - they sound okay on a quick listen but i will take them to the studio next week and check them with loud and low sine tones if there's dirt/hair in the magnet gap or on the membrane. If not, they will make fine spare parts for your M380 ... o...

I wonder if somebody came up withDarth Brooks.Even if it's just half band.

I somehwat exhausted this topic in my personal world and I'm thinking about giving away my M380 capsules. I got a small number perfectly working, a few quite good but with some overtones and a few working but with more overtones - the last ones I'll give away for postage. I will be traveling next we...

What I've been upt to in the last few months - going through used headphones/capsules to see which one have the best chance to live on in a M380. The failure rate, for what I found, is higher than 50% for capsules to be dead and for the rest, less than half pass the low sinewave test to check if the...

Congratulations for furthering the cause of us M380 belivers...and on a reanimated mic.

JohnnySomersett: To my best knowledge, the DT880 had a different capsule, but I might be wrong, as there were a few variants built over the years. The 600 ohms tests ca. 570 ohms with the multimeter. Look for pictures on the net to compare with what you got. If anybody wants I post highres pics of t...

I suspect the 250 ohms version has already a higher mass than the thin wire 600ohms, but I got to look further into that.
