MK 2

Microphone capsule


linear frequency response at 0° (free-field equalized) for placement in close proximity to sound source preferred usage: close-miking instruments

The linear frequency response of the MK 2 with respect to frontally incident sound waves results in a very natural sound for near-field recordings (i.e. in close proximity to the sound source). This capsule can be set up very close to the sound source without sounding too brilliant or harsh.

Order number

  • No. 131001 matte gray


Please note that there is some directivity at high frequencies due to the physics of sound. Thus even with an omnidirectional microphone, it still matters which way the capsule is “aimed.”

The MK 2 is often used for acoustical measurement, an application for which it has gained a considerable reputation.

A mechanical adapter (type AMBK 1, from 20 mm to 1" diameter) is available for calibration with B&K devices. Please note that because of dimensional tolerances, only the nickel-finish version of the MK 2 can be used with this adapter.
