MK4g
MK 4 capsules (and CCM 4 microphones) are optimized for maximum rejection of rear-incident sound. Typical of the classic cardioid, at 90° to its axis the attenuation is 6 dB, while from the rear it can be as much as 30 dB, depending on the frequency.
Due to its directivity, the MK 4/ CCM 4 can be placed 1.7 times farther from the sound source than a pressure transducer of equivalent sensitivity, while maintaining the same proportion of direct and reverberant sound. In the diffuse sound field (distant from a sound source in a room, for instance), this microphone type has flat frequency response except for a slight emphasis around 10 kHz.

It is ideal for speech as well as for music recordings, with a well-defined sound image free of coloration. When used for X/Y recording or as a Mid microphone in a Mid-Side configuration, it delivers exceptional results. This microphone type has the most general applicability and is the type most widely used.
