vs 75 side-address condensers
More output than 77% of 75 side-address condensers.
Each stripe is one side-address condenser with a published sensitivity, and each bar counts them; further right means more output. This mic is in blue.
vs 99 side-address condensers
Quieter than 20% of 99 side-address condensers.
Each stripe is one side-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 107 side-address condensers
Takes louder sound than 84% of 107 side-address condensers.
Each stripe is one side-address condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.
