20 – 20k Hz

Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 1. Titled "Frequency response", "1/3 Smoothed Frequency Response (Hz)"; relative dB. Which channel (one capsule or the B-format W signal), distance and room are 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. 1. Titled "Polar pattern"; three frequencies; rings every 2 dB, scale bar "dB rel. 1V/Pa" from +5 to -25. Which channel is shown is not stated: its cardioid shape suggests one capsule.
