The supercardioid has the greatest directivity of any first-order pressure gradient transducer. The response 90° off-axis is -10 dB. The polar diagram is consistent at all frequencies, which means that regardless of its direction of origin, sound will be picked up free of unwanted coloration. For this reason the supercardioid is the preferred type of microphone for dialog recording in film and video sound, particularly indoors.
From low to midrange frequencies, the directionality of a supercardioid is comparable to that of a “shotgun” microphone.
Schoeps ColetteMK 41 Capsule
The MK 41 effectively attenuates diffuse sound energy and produces a clear, "dry" sound pickup.
Its polar pattern is exceptionally frequency-independent: sounds from the side and back are strongly attenuated, but picked up without false coloration. This feature has made the MK 41 an international standard for indoor film sound.
The susceptibility of the MK 41 to acoustic feedback is lower than with any other SCHOEPS capsule type, provided that no loudspeaker radiates directly from the rear. The sensitivity minimum of the supercardioid occurs at approximately a 125° angle of incidence.
The directional effect is independent of frequency, so that off-axis and diffuse sound are picked up free of false coloration, thus sounding natural. That is a real advantage over shotgun microphones, which have appreciably greater directivity only at higher frequencies, and frequency response (and thus sound quality) that depends on the direction of sound incidence.
Thus for many situations the MK 41 offers an interesting alternative to a shotgun microphone, even if its small dimensions do not appear to suggest high directivity. As a capsule without an interference tube in front of it, the MK 41 can also be placed closer to the sound source.
