The Sennheiser MD 421N is one of the classic early versions of Sennheiser’s legendary MD 421 dynamic cardioid microphone. Built in Germany during the original production era, a microphone design that became one of the most recognizable professional dynamic microphones ever produced.

This particular example is in excellent overall condition and has been professionally converted by to standard XLR and standard low impedance, allowing straightforward connection to modern microphone preamps, interfaces and mixing consoles.

BUILD AND DESIGN

The microphone features a robust housing designed for professional studio, broadcast and location use. Internally, the MD 421 uses Sennheiser’s well-known dynamic capsule construction together with a humbucking coil, helping reduce electromagnetic interference when working around amplifiers, power supplies and other studio equipment.

Its large moving-coil capsule and carefully designed acoustic system give the microphone a combination of sensitivity, frequency extension and directional control.

SOUND CHARACTER

The Sennheiser MD 421N delivers the sound that made the original MD 421 family legendary: full, detailed and powerful with lots of bass and drama

The low frequencies are substantial and controlled, giving instruments and voices weight without becoming excessively muddy. The midrange is clear and present, while the upper frequencies retain enough detail and articulation to give the microphone a surprisingly open character.

This balance makes the MD 421 exceptionally versatile. It is equally at home on vocals, drums, toms, guitar amplifiers, brass, percussion and speech, and can handle very high sound-pressure levels while retaining clarity and definition.

HISTORICAL

Introduced at the beginning of the 1960s, the Sennheiser MD 421 quickly established itself as one of Germany’s most important professional dynamic microphone designs.

It found its way into recording studios, radio and television facilities, stages and location-recording setups throughout Europe and beyond. Its unusual combination of durability, directional performance and broad frequency response made it useful in situations traditionally divided between several different microphone types.

More than half a century later, the original MD 421 remains a standard studio microphone and one of the relatively few vintage microphone designs that continues to be used daily in modern professional recording.

POPULARITY

The MD 421 has become one of the most recognizable and widely used dynamic microphones in recording history.

While later versions continued the MD 421 name, original German-made examples such as the MD 421N remain particularly attractive for engineers and collectors looking for the construction and sound of the early production generations.

With its excellent condition, tested performance and professional XLR / low-impedance conversion, this example combines the character of an original vintage MD 421N with the convenience of straightforward use in a modern studio.
