ROGOZ AUDIO ANTI-VIBRATION AUDIO PLATFORM GRANDE FINALE / BBS

Anti-vibration platform with „sandwich” structure. Triple shelves 3 x 50 mm thick and bases 50 mm thick are separated by BBS. 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. Antivibration platforms are designed for high endaudio components. The audio 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.

The underside of the bottom shelf can be ordered in either of the following two versions:
(a) fitted with six adjustable spikes and massive protective disks, enabling the platform to be placed firmly on soft or rough and coarse surfaces.
(b) fitted with four wheels with two brakes

The platform is designed for high end audio components. Its structure has been tuned by a suitable combination of MDF, HDF, steel components (INOX, A10X, NZ3), and carbon polymer.

The photographs show a platform designed for Studer A80 reel tape recorder. On request, it can be altered to fit other audio equipment:
CD players;
Analog gramophones
Power amplifiers
Integrated amplifiers
Preamplifiers
Loudspeakers
