Direct Drive Turntable System SL-1200G-S uses a coreless direct-drive motor with Blu-ray Disc-based rotation control to greatly reduce cogging and improve speed stability. The three-layer brass and aluminum platter with damping rubber, plus a factory-balanced chassis, minimize resonance. A high-sensitivity magnesium tonearm delivers precise tracking. Output is PHONO with earth grounding, and speeds are 33 1/3, 45, and 78 rpm. The unit ships with a full accessory set.
