An acoustic dampening assembly of decoupling devices for blocking, absorbing, and deadening collision course vibrations. These decoupling devices are disposed: (a) where vibrations can be picked up by a component of the equipment from the surrounding air, (b) athwart each path of travel for vibrations through the component and particularly to and from another component, and (c) in parallel to complex resonating vibrations within associated components, for diminishing, absorbing, and blocking the transfer of such vibrations. These devices include elastomeric mounts which maintain rotating components in the rigid alignment required by design considerations, energy absorbing layers on flat surfaces, isolated sandwich cushions at points of load-bearing contact, compressing devices that produce radially-directed inward pressures, and a ballast that produces a total decoupling of the record from the turntable mechanism during play of the record.
