vs 24 side-address ribbons
More output than 100% of 24 side-address ribbons.
Each stripe is one side-address ribbon with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 272 mics
Quieter than 54% of 272 mics.
Each stripe is one mic with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 28 side-address ribbons
Takes louder sound than 11% of 28 side-address ribbons.
Each stripe is one side-address ribbon with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.
Instruments sources recommend it for most
Proximity effect: the bass it gains up close
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.
That unit is from the Multi-Angle, Multi-Distance Microphone Impulse Response Dataset (CC BY 4.0), 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
From the spec sheet, p. 2. Approximate
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 screw | Secures the ribbon in transport; fit it (mic upright) whenever the mic is moved, and remove it to record | p. 1 |
| Handling | Very fragile; sensitive to plosives and air blasts, so use a pop filter for close vocals and protect the mic when not in use | |
