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.
