 Microphone Capsule MK 2
Compact Microphone CCM 2
- omnidirectional pattern
- flat frequency
response
- corrected for the free (near) sound field
- for use
close to the sound source (frontal sound incidence)
As can be seen from the frequency response
curve, this microphone type has a flat
frequency response for frontal sound incidence.
This yields a very natural sound when recordings are made
within the reverberation radius, where the direct sound (frontal
incidence) predominates over the reverberant sound (random
angles of incidence).
This microphone type can and should be used fairly close
to the sound source – the sound image never becomes overly
brilliant or sharp – and should be directed towards it,
since there is some loss of high frequencies in sound arriving
off axis.
The MK 2 capsule has qualities of a measurement microphone
and is used in acoustimetric applications, where it has gained
a considerable reputation.
For calibration with B&K devices a mechanical adapter
(type AMBK1, from 20 mm to one inch diameter) is available.

 Microphone Capsule MK 2H
Compact Microphone CCM 2H
- omnidirectional pattern
- mild high-frequency rise
to compensate for losses at medium recording distance
Even from its appearance alone, this microphone type distinguishes
itself from the other SCHOEPS pressure transducers: the typical
grill is absent, and the sound inlet (surrounded by a gold-plated
ring) is smaller than that of other types. These special design
features lead to a frequency response that rises only above
6 kHz.
This microphone type would be used in the near field only
if a slight high-frequency emphasis were desired. It resembles
the MK 2S/ CCM 2S, though the high-frequency emphasis of the
MK 2H/ CCM 2H is audibly less pronounced and begins around
an octave higher. The primary application for this capsule
is at a greater distance from the sound source, e.g. near the
reverberation radius, when recording a large orchestra.
This microphone type is particularly designed for the recording
of classical music, a field in which it is highly acclaimed.
The choice between the MK 2H/ CCM 2H and the equally well-liked
MK 2S/ CCM 2S is essentially a matter of personal preference.

 Microphone Capsule MK 2S
Compact Microphone CCM 2S
- omnidirectional pattern
- slight high-frequency rise
to compensate for losses at recording distance near the
reverberation radius
- for universal use
The MK 2S or CCM 2S exhibits a slight high-frequency emphasis
for frontal sound incidence, with only a slight rolloff of
high frequencies off axis and in the reverberant sound field.
This microphone type represents a technically sophisticated
and attractive compromise between the two extremes represented
by the MK 2/ CCM 2 and the MK 3/ CCM 3, and is thus close to
being universally applicable.
It has been proven particularly useful in two- and three-microphone
stereo arrays, where its normal placement near the reverberation
radius of the sound field presents a sonically balanced pickup
favored by many recording engineers. These models have become
our most popular pressure transducers.

 Microphone Capsule MK 3
Compact Microphone CCM 3
- omnidirectional pattern
- corrected for the diffuse
sound field
- for use at a great distance from the sound
source
With the MK 3 or CCM 3 the aim was to create a microphone
type which would compensate for high-frequency losses and brighten
the room sound to some extent when placed at a great distance
from the sound source. Used in a reverberant sound field, well
beyond the source’s reverberation radius in a room, the
high-frequency emphasis shown in the on-axis frequency response
plot is integrated with the less brilliant off-axis pickup
and is not audible as such.
When this type of microphone is used close to the sound source,
the emphasis of high frequencies for on-axis sound incidence
becomes clearly audible, producing an overly brilliant sound
image. Therefore the MK 3/ CCM 3 is most often used as an ambient
room microphone, or in special cases when the extra brilliance
is desired.

Note:
Although our normal production tolerances are very close, we
can deliver specially matched capsule or Compact Microphone
pairs for a small extra charge. |
