Dynamic microphone

A microphone that generates its signal from a coil moving in a magnetic field, needing no power and tolerating very high sound pressure levels.

The moving coil has more mass than a condenser diaphragm, so it responds less to fast detail but survives being placed centimetres from a loud speaker cabinet. That robustness, plus a natural midrange emphasis and a rolled-off top end, is why dynamic mics are the standard choice for guitar cabinets and snare drums, on stage and in the studio. Most are cardioid, and most have a modest sensitivity that keeps stage bleed manageable.

Example: a familiar cardioid dynamic placed right against the grille captures a distorted cabinet without distorting the microphone itself.
