WARNING:
The maximum sensitivity is 100 dB SPL:
In this condition you have dynamic compression with
measurement alteration.
Sound pressure levels over 120 dB SPL
may damage the microphones.
Condenser microphones are extremely sensitive to moisture, so you should put them back in their
special carrying case after use and store them in a dry place.
Always prevent the microphone from falling, as this may cause irreversible damage. Never remove the
capsule protection.
