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 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.

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.

question

what is the specs for the bass roll off switch for the 421?
Asked by: Anonymous
There are actually 5 roll off settings on the 421. The M position is for Music and no roll off's are engaged. At the other end of the spectrum S is for Speech which is the steepest roll off. Each turn of the roll off switch offers a steeper suppression of the entire frequency range beginning roughly at 1000Hz. So if one starts at M with each click of the roll off ring one click sees 100Hz being suppressed by 4dB,another click suppress 100Hz by an additional 3dB and so on.Remember the roll off is gradual at 6dB per octave. Resulting in a gentle slope as opposed to a cut off. Best uses are Tom Tom's, electric guitar and percussion.
