GRAS RA0017 Adapter for 1" microphone and 1/2" preamplifier

Length: 4 mm
Diameter: 23.77 mm
Material: stainless steel



The GRAS RA0017 adapter is intended for the situation when you have a GRAS 1/2" preamplifier and wish to extend its use to also work with a GRAS 1" microphone. Ideally, the microphone cartridge and preamplifier should have the same diameter for a minimum acoustical influence. To install, just screw the microphone cartridge to the adapter. Then screw the preamplifier onto the adapter.


The GRAS RA0017 is a “nut” with 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 less size restrictions then consider the GRAS RA0073.
