The Sennheiser MD 421-II 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 a frequency response of 30 to 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.
