The Capacitor mic history and principle
Just before World War 2, a small company in Germany developed a
technology for the manufacture of very high quality microphones us-
ing the principle that a charged capacitor changes the voltage across
its plates when one of the plates is moved with respect to the other.
The German company developed a shape of capacitor and the gold
membrane that forms the ‘moving’ plate.
This development reached a high level of sophistication. So much
so, that to this day the finest studio microphones follow the design of
the original Neumann Company. Fortunately for some other manu-
facturers in the world, the technology of the original company in East
Germany became a part of the technology sharing policy of the Com-
munist world, and it was taken up by some specialist manufacturers
in the Far East.
Today, fine microphones are still manufactured by the original com-
pany, and by the sharing of technology, we now have a number of
products from China that are actually legitimate high quality micro-
phones in their own right. For many years, Joemeek has been mak-
ing occasional “one off”’ capacitor microphones with varying degrees
of success.
Attempts to manufacture the microphone economically while retain-
ing the superior performance were not completely successful until
Joemeek investigated some of the Far East products. The JM27 is
the result of co-operation with a Far East manufacturer and a sus-
tained program of testing in the new Joemeek studio, comparing the
production microphone with the best hand built originals, and with
some competing products. The JM27 contains all the classic design
elements and the sound of the finest microphones in the world.
