Frequency response

Angle
Distance

Frequency response: from the spec sheet (Recording Hacks copy), p. 1. Titled "Frequency Response"; axis "dB re 1 V/Pa", but the line sits about -3 dB at 1 kHz while the sensitivity is -30.5 dBV/Pa, so the scale is relative. Distance, room and smoothing not stated.

Independent measurement: also drawn, from the Multi-Angle, Multi-Distance Microphone Impulse Response Dataset (Juan Carlos Franco Hernández, Bogdan Bacila, Tim Brookes, Enzo De Sena, University of Surrey) (CC BY 4.0): one unit, measured at 1.25 m and set to 0 dB at 1 kHz, from 136 Hz up. Not the manufacturer's 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 spec sheet, p. 2. Titled "Polar Pattern"; 250, 1000, 4000 and 16000 Hz; rings every 2 dB, scale "dB rel. 1V/Pa" from +5 to -25. Measuring conditions not stated. Approximate some frequencies are identified by reasoning, not by the legend: 16k Hz.

From the quick guide
Travel screwSecures the ribbon in transport; fit it (mic upright) whenever the mic is moved, and remove it to recordp. 1
HandlingVery fragile; sensitive to plosives and air blasts, so use a pop filter for close vocals and protect the mic when not in use
