Dynamic Microphones

Changes in air pressure move the diaphragm, which moves a coil of wire attached to the back of the diaphragm. This coil surrounds a magnet, and as it moves, it creates an electrical signal in the magnetic field.


  • Limited high frequency response

  • Low sensitivity

  • Often large


  • Robust and good for live use

  • Can withstand high volumes

  • Does not require phantom power


  • kick/snare drums

  • Live vocals

  • Guitar amps

  • Some brass

Condenser Microphones

Changes in air pressure move a large plate, which acts like a diaphragm. A second, charged plate, is directly behind the 1st plate, and together they form a capacitor. As the diaphragm vibrates, the distance between the plates changes, which generates an electrical signal.


  • Fragile, expensive

  • Need phantom power

  • Can peak easily


  • Good for studio use

  • Can be very small

  • Can capture high frequency very well.


  • Vocals

  • Acoustic guitar and orchestras

  • Piano

  • Drum overheads

Ribbon Microphones

Changes in air pressure move a metallic ribbon that is suspended in a magnetic field. This generates a voltage that is proportional to the movement of the ribbon.


  • Extremely fragile

  • Very
