Modern design paired with perfect technology. That’s the new CS 550 of the brand Dual. The chassis is laquered with a special antistatic laquer in a timeless anthracite colour. The solid MDF chassis has a high rigidity and a low natural resonance. Vibrations, like for example impact noise, will be eliminated before they reach the platter and the motor. The high-class tonearm is only used on the top models CS 550 and CS 600 and was developed just for those turntables. The special hardened 7mm platter axle is turning almost frictionsless in the precise bearing made of brass. The platter is a heavy triple damped sandwich-platter with two damping rings. Additional it is effused with an special damping mass. This minimizes the natural resonance and improves, due to the heavy weight, the speed accuracy. To avoid any bad influences to the sound, we disclaimed on any kind of automatic function. Tonearm technology: The height-adjustable arm has a quadruple ball bearing Cardan joint and a particulary torsioinally rigid headshell mad of carbon fibre with ½“ mounting holes. Counterweight and antiskating are adjustable. Chassis technology: Vibration damping solid wood chassis. Heavy aluminium sandwich platter is weighted with copper rings and a cast damping mass is also located within the interior. The brass bearing is build for longlife and has a bearing mirror made of teflon. Drive technology: The platter is driven by a precision flat belt and a DC motor with electronic speed control. Cartridge is not included.
