Pointe Claire, Quebec, Canada, May 2010: This year marks the fiftieth anniversary of the introduction of the classic Sennheiser MD 421-U large diaphragm, cardioid, dynamic microphone. The venerable MD 421, which is still in production as the MD 421 II, has been one of Sennheiser’s best-selling dynamic microphones for decades thanks to its durability, versatility, and ability to handle high sound pressure levels. Offering exemplary performance on voices, but equally effective on a wide range of acoustic and amplified instruments, the MD 421 continues to be an essential component of any microphone collection in the studio or on the road.
The MD 421 has been improved over the years with upgrades to the housing, output connector, basket, and capsule assembly. A limited-production MD 421 Special Edition that recaptured the full-bodied performance of the microphone’s original design was introduced in 2003 to commemorate the 90th birthday of Sennheiser founder, Prof. Dr.-Ing. Fritz Sennheiser. The MD 421 II continues the tradition of the MD 421 while upgrading the original design in order to take advantage of improved production techniques and materials. more
