The McDonald Mount has been in use world-wide since 1985. Professional Sound Corporation has been producing and distributing these mounts in cooperation with Randy McDonald since 1990. In late 2013 PSC's Ron Meyer and Randy McDonald once again joined forces to provide you with the ultimate microphone shock mount:
The PSC M5 Pro microphone shock mount builds upon the fundamental design principles of the original PSC/McDonald universal shock mount in use world-wide since 1985. It is made from robust, light weight aircraft aluminum and utilizes a unique clear glide three stage vibration isolation system to virtually eliminate the physical transmission of all unwanted low frequency rumble and handling noise.
