More details

The CCM 8 is particularly suitable as S channel in MS stereophony, or superimposed pair at 90 ° for Blumlein stereophony.

The directivity index of a figure-8 pattern is the same as that of a cardioid but it does not record the lateral sound (perpendicular to the main axis). With its bi-directional feature, this type of microphone is a true dipole with a single membrane. It is sensitive to lateral sound, that is to say perpendicular to the microphone body and the points 0 ° and 180 ° are marked respectively by a red point and a black point on the microphone casing.

When M/S stereo recordings are made, the 0° axis normally faces to the left as viewed from behind the microphone setup. The “8“ engraved on the top of the housing should be aligned on its side so as to appear horizontal, at a precise right angle to the Mid capsule. The microphone should be placed directly above or beneath the “M“ channel microphone, and as close to it as possible.

The inherent qualities of a pure pressure-gradient transducer are readily observed in this capsule type:

  • Its sensitivity decreases at low frequencies.
  • The directional characteristic is extraordinarily independent of frequency.
  • Proximity effect is present.

The sound quality of the CCM 8 is clear and neutral. The frequency response rolls off above 16 kHz.

When an MK 8 is used as a spot microphone, care must be taken to avoid picking up early reflections or unwanted direct sound from its rear, since sound arriving from the back is picked up with full level but reversed in polarity. This could result in partial cancellation of the intended sound, which can lead to comb-filter effects at higher frequencies.
