Frequency response

Angle
Distance

Frequency response: from the manual, p. 10. Distance and room not stated (the analogue KM 184 graph says free field, IEC 60268-4). The solid curve is the nominal response; the dashed lines are its tolerance band.

Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.

Polar pattern

Polar pattern: from the manual, p. 10. Conditions not stated. Each curve is drawn on one side only (125 Hz and 250 to 1000 Hz left, 2 to 16 kHz right); the pattern is taken as symmetric.

From the manual
CapsuleKK 184 cardioid capsule (interchangeable; the KM D takes six capsules)p. 5
Sensitivity (digital)−39 dBFS, 1 kHz, 94 dB SPL, 0 dB pre-attenuation and 0 dB gain. The table lists KM D + KK 131 / KK 143 / KK 145 / KM 183 D / KM 184 D / KM 185 D; this is the fifth value.p. 6
Self-noise13 dB(A), IEC 61672-1 A-weighting, RMS. The table lists KM D + KK 131 / KK 143 / KK 145 / KM 183 D / KM 184 D / KM 185 D; this is the fifth value.
Self-noise (CCIR 468)22 dB, CCIR 468-3, quasi peak. The table lists KM D + KK 131 / KK 143 / KK 145 / KM 183 D / KM 184 D / KM 185 D; this is the fifth value.
Max SPL133 dB SPL, at 0 dBFS, 0 dB pre-attenuation and 0 dB gain. The table lists KM D + KK 131 / KK 143 / KK 145 / KM 183 D / KM 184 D / KM 185 D; this is the fifth value. The digital clipping point; the pre-attenuation (down to -18 dB) moves it up.
Signal-to-noise ratio81 dB, re 94 dB SPL, A-weighted; also 70 dB, re 94 dB SPL, CCIR 468-3. The table lists KM D + KK 131 / KK 143 / KK 145 / KM 183 D / KM 184 D / KM 185 D; this is the fifth value.
