Frequency response

Angle
Distance

Frequency response: from the manual (Recording Hacks copy), p. 13. Titled "Frequenzkurve"; relative dB. Curves labelled "10 cm", "1 m" and "180°" (at 1 m); room not stated. Approximate reading error up to about 1 dB.

Independent measurement: also drawn, from the Multi-Angle, Multi-Distance Microphone Impulse Response Dataset (Juan Carlos Franco Hernández, Bogdan Bacila, Tim Brookes, Enzo De Sena, University of Surrey) (CC BY 4.0): one unit, measured at 1.25 m and set to 0 dB at 1 kHz, from 136 Hz up. Not the manufacturer's curve.

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 (Recording Hacks copy), p. 13. Titled "Polardiagramm"; two half-plots, 125 Hz to 1 kHz on the left and 2 to 16 kHz on the right, 0° at the bottom, rings every 5 dB from 0 to -30 dB. Measuring conditions not stated. Approximate reading error up to about 1 dB.
