The RAD shock mounts provide exceptional microphone isolation from movement, handling noise and other vibrations associated with booming. The mounts come in three variations, the RAD-1, RAD-2 and RAD-3. Each mount has universal mic clips to fit any mic 19-25mm in diameter and includes a pair of standard firmness hoops and a pair of light (softer) hoops -- so you can get the best isolation for your style of booming with any mic you choose. All of the components are produced using virtually indestructible thermoplastic elastomers from high-precision injection moulding in an ISO-9000 certified factory (no 3D printing here). Made in Devon, England.
