A.S.T.S(Anti Skipping Tone-arm System)

A.S.T.S(Anti Skipping Tone-arm System) has been developed with years of experience and a number of trials, searching for the innovative tone-arm for professional DJ's.This system breaks all of the historic common sense, achieving its non skipping performance in hard scratching. A.S.T.S consists of two inventions, short/straight arm and TH (Tracing Hold) balance system.

●TH balance system gives horizontal movement in addition to vertical. This movement gives much more stable balance (vertical direction) to the needle. The combination of short / straight arm and TH balance system gives the best stability to the needle, which enables anti-skipping in hard scratching.

●The brass arm with aluminum cover is used for A.S.T.S . This combination results in the best pick up sensitivity as well as the best resistance to howling. This new tone-arm allowed A.S.T.S to increase the resistance against the howling by over 50% compared to the normal aluminum arm.
