The G.R.A.S. RA0072 adapter is intended for the situation when you have a G.R.A.S. 1/2" preamplifier and wish to extend its use to also work with a G.R.A.S. 1" microphone. To install, just screw the microphone cartridge to the adapter. Then screw the preamplifier onto the adapter.


The G.R.A.S. RA0017 is designed for a minimum acoustical influence on the measurement. It has an inner threading for the preamplifier and outer threading for the microphone. The adapter is made of high quality stainless steel. The microphone cartridge and preamplifier interconnects directly and thereby no attenuation is introduced. This means that the characteristics of the microphone are maintained.


In setups with size restrictions then consider the G.R.A.S. RA0017.
