Switchable Microphones
 Microphone Capsule MK 5
Compact Microphone CCM 5
- omni and cardioid patterns, mechanically switchable
- slight emphasis of the high frequencies
- broad range of
applications
The MK 5/ CCM 5 operates with only one membrane, but offers
two selectable directional patterns. The pattern is selected
purely by mechanical means, via a slide switch on the side
of the capsule.
In its omnidirectional setting the capsule is a pressure
transducer with flat response down to the lowest audio frequencies.
The polar diagram shows increasing directivity at high frequencies,
which is typical for this type of transducer.
In the cardioid setting equal components of pressure-gradient
and pressure operation combine to form a cardioid pattern.
(Please make certain that the pattern selector is definitely
in one position or the other; in-between settings will yield
undefined results.)
The fact that response is maintained to the highest audible
frequencies is unusual for a switchable-pattern microphone.
The MK 5/ CCM 5 has a slight high-frequency emphasis as
compared with the corresponding single-pattern omni (MK 2/
CCM 2) and cardioid (MK 4/ CCM 4). The MK 5/ CCM 5 has near-universal
usefulness and it is the capsule which we recommend most
highly for those just starting out with the Colette Series.
Surface finish : matte gray (g) or nickel (ni)
Note:
Although our normal production tolerances are very close,
we can deliver specially matched capsule or Compact Microphone
pairs for a small extra charge.
 Microphone Capsule MK 6
(not available as Compact Microphone)
- omni, cardioid and figure-8, mechanically switchable
- very broad range of applications
- main axis: lateral (perpendicular
to the microphone body)
The MK 6 operates with a single diaphragm. When the ribbed
cap of the capsule is rotated, a system of internal shutters
alters the acoustic chambering around the diaphragm to change
its characteristic from omni to cardioid to figure-8, then
back through cardioid to omni. (There is no functional difference
between the two available cardioid settings.)
In the omnidirectional setting it is a true pressure transducer
with flat response down to the lowest frequencies. In this
setting the MK 6 shows an increasing directivity toward the
high frequencies which is typical for such a transducer.
As with the MK 8, the 0° axis is perpendicular to the
body of the microphone and is indicated by a red dot at the
lower rim of the capsule. A black dot marks the 180° direction.
As with any microphone whose switchable patterns include
the figure-8, the frequency response is neither as flat nor
as extended in the high-frequency region as with the capsules
described earlier. However, in the figure-8 setting, the
MK 6 closely resembles the MK 8.
Note:
Though not specifically designed for such use, the MK 6 capsule
can also be used on the RC Active Tube or the variable
angle joint GVC; when fully tightened it will rarely be
aimed where you intend. On request we will supply an elastic
ring which can be slipped over the threads of the RC or
GVC so that the final turn of the capsule will place it
at the desired angle of rotation.
