GRAS RA0118 Attenuator for 1/4" microphones


Recommendation: Choose a microphone with low sensitivity instead of using the RA0118.


The RA0118 is an attenuator for inserting between a 1/4" prepolarized or externally polarized microphone cartridge and preamplifier. It attenuates the output signal of the microphone by approximately 16 dB in order to avoid overloading the preamplifier or following analyzer. The RA0118 is useful when measuring very high sound pressure levels using a preamplifier or analyzer with limited dynamic range.
