Type 40DP

Type 40DP
The Type 40DP is a 1/8" microphone for very high level and high frequency measurements. Its low sensitivity makes it ideal for measuring very high sound pressure levels of up to 184 dB (10% dist.)
Its small size reduces the disturbances in the sound field, resulting in a frequency range up to 140 kHz.
