GRAS AF0008 Adapter for 1/4" preamplifier and 1/2" microphone



The GRAS AF0008 is an adapter for using a 1/2" microphone cartridge with a GRAS 26AB 1/4" preamplifier.


The GRAS AF0008 is a tube which gives a longer continuing 1/2" diameter of the combined assembly. Thereby it is designed for a minimized acoustic influence from the measurement setup for free-field measurements. The adapter is made of high quality stainless steel. The dimensions are shown on a drawing under the tab “System Setup”. Theoretically, the tube should be infinitely long. 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 restricted space or in pressure measurement setups where the preamplifier is not exposed to the measured sound, then you should consider the GRAS GR0010. Consider also the GRAS RA0003 adapter for any standard microphone i.e. will fit microphones cartridges from other manufacturers as well as from GRAS
