German manufacturing company that once made things like
microphones,
amplifiers and
radios. Telefunken now just makes giant
antennas and powerful fm broadcasting equipment.
Frank Zappa sings about a Telefunken U-47 in Joe's Garage. I always thought it was just a nonsense phrase, but it turns out that it's really a microphone that was manufactured by Neumann and sold with a Telefunken label.
