Frequency response

Angle
Distance

Frequency response: from the manual (Recording Hacks copy), p. 6. Titled "Frequency response curve", "0°, 1 m"; drawn as absolute sensitivity (dBV). Room and smoothing not stated.

The manufacturer draws absolute sensitivity (dBV/Pa); shifted here by a constant so 1 kHz is near 0 dB.

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. 6. Titled "Polar diagram". Each frequency is drawn on one side only (125 to 1000 Hz left, 2000 to 16000 Hz right); the pattern is taken as symmetric. Measuring conditions not stated.
