Schoeps话筒麦克风 MK 41 话筒头 微型话筒  Schoeps MK41

话筒拾音头 MK 41

超心形拾音头在频率范围内具有高度一致的指

向性

用于音乐和人声拾音

较短的“枪式”话筒，在中频区域具有更高的指向性

通常适用于影视同期声的录制和管弦乐队的点话筒

MK 41 具有很强的指向性，离轴声的衰减比心形话筒更大。与其它类型的SCHOEPS话筒拾音头相比，这类话筒的拾音显得“更涩”，且不易受声音回授的影响（扬声器不能直接位于话筒的后方轴线上）。

其指向性不依赖于频率，从而偏离轴向的声音和混响声都没有声染色。因此,即使作为远距离的拾音头也能产生非常自然的声音。这一点比带有干扰管的枪式话筒（其指向性依赖于频率，只有在高频率范围指向性才会胜过超心形）更具优势。干扰管话筒对空间的摆放位置非常敏感，改变反射模式将导致声音染色的改变。因此与枪式话筒相比，MK 41 更有效、节省空间、体积更小，也可以被放置得离音源更近。

当采用M/S话筒摆放时，如果用 MK 41 作为“M”通道，可以将它放在离音源远一些的位置。

与心形 MK 4 话筒相比，由于梯度效应，MK 41在低频末端会有较多的滑落。它的扩散声场响应提升比 MK 4 小。

MK 41 MICROPHONE CAPSULE

PROPERTIES

Supercardioid directional pattern

High directivity, at low and medium frequencies comparable to that of a shotgun microphone

Natural sound due to flat frequency response which remains largely the same for all directions of pickup. This is particularly important for indoor recording

Preferred uses: recording dialogue for film sound; as a spot microphone in the orchestra and on the opera stage.

DESCRIPTION

The MK 41 effectively attenuates diffuse sound energy and produces a b, "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 approximaby 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.
