Frequency response

Angle
Distance

Frequency response: from the spec sheet, p. 2. Titled "Frequency response curve ± 3 dB", "0 dB = 1.5 mV/Pa"; "measuring tolerance ± 3 dB", "correspond to a typical production sample". Mounting (on a boundary or not), 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. Untitled polar under "Frequency response & polar pattern" ("a typical production sample"); one full circle, 0° at the top, 5 dB rings to -20 dB. Measuring conditions and mounting not stated.

From the manual
Placement (beyerdynamic)Lay it in the bass drum or cajon; on a grand piano, inside the body, e.g. on the cast frame. Tilting it changes the sound (half-cardioid)p. 1
