Schoeps MK 4P

Cardioid Microphone Capsule for Close Pickup


Schoeps MK 4P

This Schoeps MK 4P cardioid capsule is designed for the very closest speech pickup, i.e. directly in front of the speaker’s mouth.

Its low-frequency roll-off is compensated by the proximity effect. Thus it has (up to the point of its high-frequency emphasis) a flat frequency response for the speaker’s voice while showing a roll-off at low frequencies for all sound that originates from a greater distance. As a result, background sounds are picked up less strongly than the person speaking.


  • Cardioid for close speech pickup (<20 cm)
  • Low-frequency response roll-off (-6 dB at 100 Hz)
  • Polar diagram is identical to the MK 4
  • Preferred applications: close speech pickup, public address systems
