Manufacturer Description:


  • cardioid pattern
  • for pickup of speech or music at close range (under 10 cm), otherwise the sound may become “thin“
  • reduced sensitivity
  • considerable attenuation of low frequencies

When cardioids are used in some situations, e.g. as hand-held microphones for vocalists or announcers, proximity effect can become quite prominent. In addition, the output level can become much higher than that of the other microphones being used at the same time, which may be more distant and / or of dynamic type. Neither characteristic is desirable. So SCHOEPS offers the MK 4S / CCM 4S in a special version known as the MK 4A or CCM 4A (“A“ for “attenuation“), with a stronger low-frequency rolloff and 10 dB lower sensitivity.


This microphone type is recommended for use exclusively in situations of very close pickup and high sound pressure levels. At greater distances it would only deliver a low output level, resulting in an effective reduction in signal-to-noise ratio.
