Sennheiser MD 421 Microphone

Here’s a favorite microphone of disc jockeys; a high quality cardioid dynamic unit designed and made in Germany. The Sennheiser MD 421 came out originally back in the 1960s. This mic is still used at radio stations all over the country to this day.

The MD 421 has a robust sound; it has a slight boost in the mid-high frequency range for a brilliant response. The MD 421 is also fitted with a low frequency roll off switch to compensate for close talking.

All in all the MD 421 is an excellent choice for radio control rooms and is a top choice of many announcers and voice-over artists. So we chose the MD 421 to add to our Mr. Microphone line-up on the Modesto Radio Museum site!
