GRAS OP0023 Kit for Sensitivity Calibration of Flush-mount Microphone Sets



For sensitivity calibration of our flush-mount microphone sets, you will in addition to a Pistonphone (e.g. GRAS 42AP) need an adapter for each microphone size.
This kit contains adapters for 1/8”, 1/4" and 1/2" sizes which fit into the GRAS RA0048 1/2" coupler. This coupler is included with GRAS Pistonphones.
