Microphone capsule


  • moderate high-frequency response elevation at 0°, which compensates high frequency losses caused by the increased diffuse field amount when used near the reverberation radius
  • often used for A/B stereo, Decca Tree or as a room microphone

The MK 2S is our most popular pressure transducer.

Its somewhat brighter sound (compared to the MK 2 and MK 2H) makes it ideal for use as a main microphone or room microphone, especially in larger rooms.

Here is a nice comparison of main microphone pairs consisting of two MK 2S.
Kazuya Nagae is teaching at the Nagoya University of Arts in Japan.


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 2XS, 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
