Supercardioids
Microphone Capsule MK 41
– supercardioid with highly consistent directionality
throughout its frequency range
– for music and speech
– high directivity, comparable to that of a short “shot-
gun“ microphone up through mid range frequencies
– often preferred for use in film sound recording and
as a spot microphone in orchestras
The MK 41 is strongly directional. Sound arriving from
off axis is attenuated even more than with a cardioid.
The pickup is “drier” and less susceptible to acoustic
feedback than any other SCHOEPS capsule type (a loud-
speaker should not be located directly along the rear
axis of the microphone, however).
Its directivity is highly independent of frequency, so
that even sounds arriving off axis and reverberant sound
are registered without coloration. Consequently, even
distant placement of the capsule produces a very natu-
ral sound pickup. This is a real advantage over interfer-
ence-tube “shotgun” microphones, whose directivity is
very frequency-dependent – exceeding that of a super-
cardioid only at higher frequencies. Inter ference-tube
microphones are notoriously sensitive to their position
in a room, where the shifting patterns of reflections
cause cor responding shifts in sound color. Thus the
MK 41 are sur prisingly effective, space-saving alterna-
tives to shotgun microphones – and being small, they
can often be placed closer to the sound source.
(Regarding shotgun microphones, see also page 129.)
An M/S microphone arrangement can be set up at
quite some distance from the sound source if an MK 41
is used for the “M“ channel.
Compared to the cardioid MK 4, the MK 41 has
slightly more rolloff at the low end due to the gradient
effect. Its diffuse field response elevation is less than
that of the MK 4.
