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