Sota Moonbeam turntable

The job of any turntable is simply to rotate a record at precise speed with a total absence of extraneous vibration and noise. However, during the record playing process, every part of a turntable is subject to a variety of internally and externally caused vibrations. To deal effectively with the distortions caused by these vibrations, each distortion-generating mechanism must be addressed and resolved if it is to achieve the goal of bringing you closest to the musical experience.
The Series III MOONBEAM carefully identifies and addresses each variable that undermines pure signal retrieval.
The main platter, as well as the sub-platter, utilized on the Series III MOONBEAM is made of a special high-density polymer. The special high-density polymer, precision-machined platter is virtually inert and is therefore effective in dissipating the resonant energy generated by the record-playing process, without the substantial costs of a properly damped aluminum platter system. To further neutralize the resonant LP, an energy damping interface mat in added to the thick Plexiglas main platter.
The spindle/bearing assembly of the MOONBEAM is a state-of-the-art design. Once again, SOTA has turned to the performance advantage of polymers. The bearing cup is manufactured of a high-tech material called Turcite™. Turcite™ is a Teflon-impregnated, self-lubricating polymer designed specifically for ultra-precise bearing applications, and is ideally suited to the turntable spindle/bearing function. In turn, the bearing has a nearly unlimited life and is significantly quieter than even the most expensive and precise metal-to-metal bearing assembly.
The drive system of the MOONBEAM consists of a sub-platter driven by a 24-pole AC synchronous motor designed for ultra-precise computer use. AC motors have the advantage of suffering no speed drift over time, making them ideally suited for precision turntable use. The motor drives a precision-ground, low tension belt which provides a vibration-free drive system for the rotating assembly of the turntable. The MOONBEAM is equipped for both 33 and 45 RPM speeds.
The chassis of the Series III MOONBEAM continues the design theme of isolation from noise and spurious vibrations. Environmental isolation means isolating the moving platter from all the physical and mechanical threats (footfalls, room resonances, air-borne waves) that will ultimately disrupt the retrieval of the information. The MOONBEAM accomplishes this task by way of its solid layering of an internally damped chassis, which effectively isolates the turntable system. Additionally, the MOONBEAM utilizes special energy-absorbing leveling feet to further damp vibrations. Furniture-quality wood veneer enhances this newly designed Series III MOONBEAM. The S202 precision tonearm is a straight, fixed-head tonearm with near frictionless movement. This design offers maximum rigidity, optimal coupling of cartridge to arm, and minimizes spurious resonances.
