THREE-POINT APPROACH
• JEWEL is mounted to the spindle via a so-called shaft seal. The unique design of the shaft seal ring ensures a stable connection with the spindle. The elastic coating of the ring neutralizes the vibrations, that might be transmitted via the spindle. At the same time, the expandable NBR rubber coating allows JEWEL to be used on a wide variety of record players with different spindles. The material NBR (nitrile butadiene rubber) is an elastomer with excellent mechanical properties and has high abrasion and tensile strength. There is a coil spring around the center hole inside the shaft seal that serves to additionally stabilize the spindle mount.
• Eight brass rods are suspended independently of each other in the body. As soon as JEWEL is placed on the record, the rods plunge down and gently touch the surface. These transmit some of the resonances inside JEWEL, where they are eliminated. The suspension allows the individual rods to adapt perfectly to any differences in height of the record surface caused by different label structures. This ensures that the contact surface of the brass rods remains constant for all records.
• In collaboration with Sorbothane Inc., they have developed a unique Sorbothane damping ring. This was developed according to their specifications for the function, mass and shape of JEWEL and ensures balanced damping of unwanted vibrations and resonances from records.
Sorbothane is a proprietary, viscoelastic polymer. Viscoelastic means that the material has properties of both liquids and solids (elastic materials). Sorbothane combines shock absorption, good memory, vibration isolation and vibration damping. While many materials have only one of these properties, Sorbothane combines all of them in a stable material with a long service life.
