Power None: a dynamic mic needs no power.
- Type
- Dynamic
- Pattern
- Figure-8
- Sensitivity
- −46 dBV/Pa
- Among 311 mics: more output than 41%
- Max SPL
- 140 dB SPL
- Among 343 mics: takes louder sound than 56%

vs 78 dynamics
More output than 99% of 78 dynamics.
Each stripe is one dynamic with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 36 dynamics
Takes louder sound than 20% of 36 dynamics.
Each stripe is one dynamic with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.
Proximity effect: the bass it gains up close
From the data sheet rh, p. 2.
Titled "Frequency response curve (± 2.5 dB)", "Measuring distance" with curves labelled "1 m" and "2 cm"; "correspond to typical machine run specifications for this microphone". Room and smoothing not stated.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
