To avoid possibly damaging the microphone, the RA0038 can be used with a microphone fitted with its protection grid, e.g. a GRAS 40AG and a suitable preamplifier, like GRAS 26AS which is a 1/4″ very short preamplifier with 3 m integrated cable.

The RA0038 is also part of the GRAS 43AB Artificial Ear.
