Capsule Head KK 143 (nx)

KK 143 is a pressure gradient transducer
with wide-angle cardioid characteristic.
Attenuation: 4 dB at 90°, 8 dB at 135°,
and 11 dB at 180°. The frequency re-
sponse for sound sources within an an-
gle of ± 90° (off axis) is parallel up to
12kHz.

Capsule Head KK 185 (nx)

KK 185 is a pressure gradient transducer
with a hypercardioid characteristic. At-
tenuation of sound incidence from the
side or rear is approximately 10 dB. Min-
imum sensitivity occurs at an angle of
about 120°.

Capsule Head KK 145 (nx)

KK 145 is a pressure gradient transducer
with cardioid characteristic just like the
KK 184. However, it has an acoustic
bass roll-off characteristic in the free
field and therefore suppresses interfer-
ing LF noise (wind, structure-borne
noise).
Since proximity effect is a natural fea-
ture of pressure gradient microphones,
the KK 145 appears to be optimized for a
flat frequency response at a recording
distance of approximately 15cm (speech
cardioid).

Capsule Head KK 183 (nx)

KK 183 is a diffuse-field equalized pres-
sure transducer with a free-field treble
boost (approx. 7 dB at 10 kHz). The fre-
quency response in the diffuse sound
field is flat up to 10 kHz.

Capsule Head KK 184 (nx)

KK 184 is a pressure gradient transducer
with cardioid characteristic. The fre-
quency curves are very even and parallel
to 0° sound incidence. In typical usage,
there is no coloration of sound over a
wide pickup angle.

Capsule Head KK 131 (nx)

KK 131 is a free-field equalized pressure
transducer. The sensitivity in the free
sound field is flat up to 20 kHz. In the
diffuse sound field there is a roll-off
above 5 kHz.
