Frequency response

Angle
Distance

Frequency response: from the user guide, p. 13. Free field, distance and smoothing not stated; the sheet draws a tolerance band (dashed) around the 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 user guide, p. 13. Rings every 5 dB, labelled 0 to 25 dB down (the 25 half hidden by the curves); 0° at the top. Left half: up to 1 kHz and 2 kHz; right half: 4, 8 and 16 kHz (outer to inner). Measuring conditions not stated. Approximate reading error up to about 1.5 dB; some frequencies are identified by reasoning, not by the legend: 125 Hz, 250 Hz, 500 Hz, 1k Hz, 2k Hz, 4k Hz, 8k Hz, 16k Hz.
