Power P48 phantom (IEC 61938).
- Type
- Condenser
- Pattern
- Cardioid
- Sensitivity
- −38.4 dBV/Pa computed
- Self-noise
- 14 dB(A)
- Among 258 condensers: quieter than 59%
- Among 272 mics: quieter than 60%
- Max SPL
- 147 dB SPL
- Among 277 condensers: takes louder sound than 86%
- Among 343 mics: takes louder sound than 84%

vs 104 end-address condensers
Quieter than 71% of 104 end-address condensers.
Each stripe is one end-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 110 end-address condensers
Takes louder sound than 94% of 110 end-address condensers.
Each stripe is one end-address condenser 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, p. 2.
Graph with lines labelled "0°" and "180°"; relative dB (0° is 0 dB in the mids). Distance, room and smoothing not stated. Drawn from the left edge (40 Hz) to the right edge (20 kHz).
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.
Three polar plots, 0° up, each with 1 kHz and two other frequencies; rings labelled 0, -6, -12, -18, -24 dB. Measuring conditions not stated.
