The aluminium die-cast chassis is rigidly integrated with a special material consisting of ABS mixed with glass fiber to achieve a two-layer construction. The insulator consists of a spring and rubber to provide optimal vibration-damping characteristics. The tonearm is a static-balance universal S-shape tonearm, another Technics tradition. By adopting a high-precision bearing using the same gimbal suspension construction and machined housing as the SL-1200 Series, high initial sensitivity is achieved. In addition, reliability has been improved by incorporating a removable power cable and gold-plated terminals, which have less sound quality degradation, for the PHONO and LINE terminals.
