The SM-1 Shock Mount is an 8-point flexible suspension support system that helps suppress low-frequency rumble on the microphone line by absorbing and damping vibrations picked up from the studio desk or console.

The SM-1 is designed for use with the slim-line Heil Sound microphones, such as the PR 20. Its 5/8" threads mount onto the PL-2T "Topless" and other mounts, for easy installation.
