The Sennheiser MD 421 Microphone is a cardioid dynamic microphone widely used in the recording and broadcast industry. Known for its versatility, the MD 421 is praised for handling various applications thanks to its flexible bass control. The microphone features a 5-position bass roll-off switch and a frequency response range of 30 to 17,000 Hz. The cardioid polar pattern effectively rejects off-axis noise from room acoustics and external sounds, while also providing strong feedback rejection, especially in situations with monitors positioned nearby.
The MD 421 features a dynamic capsule, ensuring consistent signal response whether used up close or at a distance. This is particularly useful in broadcast settings, allowing announcers and DJs to move around without affecting sound quality. Additionally, the MD 421 can handle high sound pressure levels, making it ideal for miking instruments with high transient responses.
