Ortofon RS-309D Tonearm
RS-309D - 12 inch - Ortofon’s D series tonearms take analog sound reproduction to a higher level with highly configurable VTF options, and a dynamic balance system for increased stability when tracking warps and other anomalies. D series tonearms can be used for a wide array of cartridges, feature anti-skating control.
Unlike the conventional dynamic-type tonearms that are prone to the adverse effects of spring vibration, the RS tonearm completely eliminates external vibration by implementing a spring mechanism housed within the pivot case.
