Schoeps MK 4

Small-diaphragm cardioid condenser capsule (Colette series), on a CMC 6 amplifier

Approximate Some readings for this mic are uncertain; see the graphs.

Power Phantom, 12 V or 48 V (CMC 6, automatic switchover).

Type

Sensitivity
−37.7 dBV/Pa computed
Self-noise
15 dB(A)
vs 104 end-address condensers

Quieter than 62% 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.

  • Among 258 condensers: quieter than 53%
  • Among 272 mics: quieter than 54%
Max SPL
132 dB SPL
vs 110 end-address condensers

Takes louder sound than 17% 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.

  • Among 277 condensers: takes louder sound than 26%
  • Among 343 mics: takes louder sound than 24%
