Schoeps MK 8

Figure-8 Microphone Capsule

Description

The MK 8 is often used for M/S and double M/S stereo sound in film sound and music recording, in combination with Colette or CCM microphones and/or a CMIT shotgun microphone.

This type of capsule is a pure dipole. The figure-eight pattern of the MK 8 remains constant from low to high frequencies, which is particularly important when used in an M/S setup. Its sensitivity rolls off more at low frequencies than other capsules, but proximity effect (which can compensate, given relatively close placement) is also more pronounced.

Production of the MK 8 is a special technical accomplishment because, in terms of physics, the available force due to the pressure gradient is minimal. Despite this, the MK 8 has an excellent frequency and polar response, near-perfect front/back symmetry, and low inherent noise.

The microphone is comparatively sensitive to solid-borne sound as well as wind and breath noise. Good protection should be considered, e.g. suitable wind screening and/or shock mounting.

The pickup direction is lateral, i.e. perpendicular to the microphone housing, and the 0° and 180° axes are indicated respectively by red and black dots on the capsule housing. When recording with M/S, the 0° axis (as viewed from a position behind the microphone) should point to the left, and the “8” engraved on top of the capsule should be precisely horizontal.
