RPM 1 Carbon utilizes a lot of innovations and enhancements: A low resonance chassis holds a newly designed inverted platter bearing with ceramic ball for further reduced rumble. An outboard 15V AC motor is smoothly driven using an ultra-precision AC generator with DC power supply for further enhanced speed stability. A completely new designed S-shaped tonearm tube is made from carbon fiber, aluminum and resin. Using a complex 3-step process with heat treatment and 100 bar pressure, the arm tube rigidity is strengthened, internal damping is maximized and resonances are reduced to a minimum. This makes the tonearm also suitable for MC cartridges. Additional features include a new magnetic antiskating mechanism and a TPE-damped counterweight.
