Microphone Capsule

  • omnidirectional pattern
  • slight high-frequency rise to compensate for losses at moderate recording distances
  • for a very wide range of recording applications
  • often preferred for “spaced microphone” stereo pickup and “Decca Tree” arrangements

The MK 2S exhibits a slight high-frequency emphasis for frontal sound incidence, with only a slight rolloff of high frequencies off axis and in the reverberant sound field.
This frequency response characteristic falls between that of the MK 2 and the MK 3, making the capsule suitable for a wide range of applications.

The MK 2S has proven particularly useful in two- and three-microphone stereo arrays, where its placement near the reverberation radius of the sound field presents a sonically balanced pickup favored by many recording engineers. This model has become our most popular pressure transducer.

For spaced microphone (“A/B”) stereo recording and especially the “Decca Tree” method, KA 40 accessory spheres are recommended; please see page 114.
