Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. "Frequency Response", Cardioid graph, solid red line (flat). Axis "dB re 1 V/Pa", but 0 dB at 1 kHz, so relative. Distance, room and smoothing not stated.

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

Polar pattern

Polar pattern: from the spec sheet, p. 2. "Polar Pattern", cardioid capsule; 500 Hz, 1 kHz and 4 kHz; rings every 2 dB, scale "dB rel. 1V/Pa" from +5 to -25.
