ROGOZ AUDIO ANTI-VIBRATION PLATFORM 4SG50/BBS

Four-legged platform. The legs contain quartz sand as ballast. The 50 mm thick top is made of wood (MDF), covered in natural wood veneer (palisander). The shelf is separated from the stand frame by the Balancing Board System. BBS has kinematic and dynamic qualities which enable isolated masses to “float” to the sides relative to the system axis, maintaining point support at the same time. BBS also makes it possible to level the stand shelves.

Anti-vibration platforms are designed for high end audio components. The frame has been tuned by a suitable combination of alloy steel and high-fiber content steel. The frame consist of extra-strong legs made of carbon steel S235JR (which is used for load-bearing stuctures subject to heavy dynamic load, e.g. in cranes) connected by crosspieces made from higher-strength alloy steel S355. Adjustable anti-vibration spikes are used for for high-precision leveling.

BOARD BALANCING INVOLVES HORIZONTAL PLANE MOVEMENT IN ALL DIRECTIONS

Balancing Board System The platform structure incorporates a new proprietary Rogoz Audio antivibration system, BBS (Balancing Board System, Patent P.404137). The system consists of a threaded, height-adjustable spike made of high-fiber-content steel alloy, on top of which two elements are placed, each with an inner bearing. An intermediary (middle) element is made of carbon fiber and supports another element, a steel bearing inserted into the shelf. Point contact between the steel spike and the carbon intermediary element prevents movement of either element relative to its axis, but it allows pendular motion. Meanwhile, the contact between the intermediary element and the bearing inserted into the shelf allows restricted rolling motion and sliding motion. Consequently, the advantages of spike point support (contact area has been minimized and kinetic energy turns into heat) have been combined with the effects of deadening vibrations owing to to sliding friction and rolling resistance.
