Microphone Capsule MK 4
– classic cardioid, with consistent directionality through-
out its frequency range
– suitable for the widest range of applications, either
as a spot microphone or for stereo recording with
coincident, ORTF or M/S microphone arrangements
– often preferred for singing or speaking voices and
most instruments
The MK 4 is our best-selling capsule. It offers the high-
est sound quality, flat frequency response, optimal
rejection of rear-incident sound, and a directional pat-
tern that remains constant throughout the audio fre-
quency range. In the diffuse sound field it shows only
a mild rise around 10 kHz; the sonic impression thus
remains free of coloration even when sound is arriving
from all sides at once. The sonic impression is thus
free of coloration whether sound is arriving at the
front or at the sides of the microphone, as well as for
diffuse sound (reverberation) in a room.
For those who dare to use their ears rather than just
their eyes when choosing a vocal microphone, a Colette
microphone using the MK 4 capsule can be a remark-
able instrument. It is often preferred by opera singers
and other trained vocalists. But its natural, transparent
character also suits it very well for use in pop and rock
applications, on stage or in the studio, where equaliza-
tion is a part of the plan. A microphone with a clear,
neutral sound quality provides the ideal point of
departure whenever special “coloring” is needed.
