The G.R.A.S. RA0216 is an adapter to be used for field-verification of the 1/2" flush-mount microphone which is part of G.R.A.S. 67AX & 67AD. In addition to the actual adapter, a ring with two fingerscrews are included. Thereby the adapter can be firmly attached to the plate which has corresponding threaded holes.
The adapter fits both pistonphones (e.g. 42AP Intelligent Pistonphone) and the G.R.A.S. 42AB Sound Calibrator.
In addition, the adapter can be used for field verification of 1/2", 1/4" or 1/8" flush-mounted microphones in test objects. In this case the included ring is not used.
