A dynamic mic with flexible bass control -frequency range 30Hz - 17kHz


The Sennheiser MD 421-II - Classic Studio Microphone is a cardioid, dynamic microphone popularized by the recording and broadcast industry. The MD 421-II is favored for its ability to handle a variety of applications due to its flexible bass control. The microphone features a 5-position bass roll-off switch and frequency response of 30-17,000 Hz. The cardioid polar pattern effectively rejects off-axis noise due to room acoustics and noise, and also provides effective feedback rejection often caused by monitors positioned within close proximity.

The MD 421 II features a dynamic capsule, allowing even signal response whether close-up or at a reasonable distance. This is particularly useful for broadcast applications, where announcers and DJs can refrain from remaining absolutely stationary. The MD 421-II also handles very high sound pressure levels, making it suitable for miking instruments high in transient (peak) response.

  • Dynamic Capsule - The MD 421 II features a dynamic capsule, resulting in even signal response in close and reasonable distances as well as the capacity to handle high SPL levels.
  • Cardioid Polar Pattern - The cardioid polar pattern is effective in attenuating off-axis noise and ambiance. The cardioid polar pattern is also effective in rejecting feedback due to monitors.
  • 5-Position Bass Roll-Off - The 5 position low frequency roll-off switch offers flexible bass attenuation allowing the microphone to be used in a variety of situations.

    I have wanted one of these mics since my sound engineering days many years ago - it is just as good now as it was then and so much better than many modern mics I have used since.

    Always wanted this mic but couldn't quite justify the expense given I already have great mics so getting this on special was a treat and glad to have it. If you have a deep male singing voice this is a great mic to have. Of course its also great for guitar cabs and percussion etc. Very fast delivery thanks!
