Electro-Voice ND68
Dynamic supercardioid kick-drum and low-frequency instrument mic
Approximate Some readings for this mic are uncertain; see the graphs.
Power None (passive). Low output: it needs a lot of preamp gain.
- Type
- Dynamic
- Pattern
- Supercardioid
- Sensitivity
- −61.9 dBV/Pa
- Among 78 dynamics: more output than 5%
- Among 311 mics: more output than 2%
- Max SPL
- 140 dB SPL
- Among 36 dynamics: takes louder sound than 20%
- Among 343 mics: takes louder sound than 56%
- Rated range
- 20 – 11k Hz
vs 44 end-address dynamics
More output than 9% of 44 end-address dynamics.
Each stripe is one end-address dynamic with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 19 end-address dynamics
Takes louder sound than 11% of 19 end-address dynamics.
Each stripe is one end-address 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 spec sheet, p. 2.
Titled "Frequency Response"; relative dB, 0 dB labelled; lines marked "1 m" (solid), "5 cm" (dotted) and "2.5 cm" (dashed). 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
From the spec sheet, p. 2. Approximate
Titled "Polar Response": four full-circle plots, two frequencies each (solid and dashed, as the legends under each plot say); rings labelled -5dB to -20dB, centre circle -25 dB. Measuring conditions not stated.
Approximate: reading error up to about 1 dB.
