Suitable for mounting gooseneck microphones into solid surfaces, such as lecterns, with a high level of isolation from vibration and impact noises. It comprises a black plastic flange that fits into a 50mm diameter cut-out in the surface, with a complex, rubber shock-mount moulding. This accommodates microphones with XLR connectors at the base (around 19mm diameter).
As a theft deterrent, if a Neutrik XLR locking cable connector (stock code 40-319) is used, with its hex screw tightened, the microphone cannot be removed without use of tools.
