The main chassis consists of a complex sandwich of materials:aluminium-bullet-proof-wood-aluminium.Within the precision-machined bullet-proof-wood layer,clearaudio have introduced an elaborate resonance damping measure:an internal 'mat' comprising approximately 100,000 tiny stainless steel balls.The powerful and smooth running DC motor is integrated within and is effectively decoupled by the main chassis.Clearaudio's OSC 'Optical Speed Control' technology continuously monitors a micro infra-red strobe to ensure exact speed stability.The motor drives the precision machined aluminium sub-platter via a precision machined POM main platter are supported by clearaudio's patented CMB 'Ceramic Magnetic Bearing'.The drive system is operated by four blue illuminated buttons, ergonomically integrated into the front left of the chassis.
