Direct Drive Manual Turntable SL-1210G-K uses a coreless direct-drive motor with no iron core to eliminate cogging and Blu-ray-inspired rotation control for precision. It features a three-layer platter with deadening rubber to minimize resonance, a factory-balanced chassis, and a magnesium tonearm for improved damping. With 33-1/3, 45, and 78 rpm, it provides stable speed, low wow and flutter, and reliable analog playback for professional installations.
