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.
