The SL-1200G turntable uses a three-layer construction that solidly integrates aluminium diecast with brass weight and has deadening rubber attached to the entire rear surface to eliminate unwanted resonance thereby achieving high rigidity and excellent vibration damping characteristics. At 3.6 kg the total weight of the SL-1200G platter is more than twice that of the SL-1200MK6 and achieves an inertial mass surpassing that of the SP-10MK2 which was used by broadcast stations.
