A.S.T.S (Anti Skipping Tone-arm System)
The A.S.T.S (Anti Skipping Tone-arm System) was years in trial and development. Initially the quest was to improve on the
tracing of tone arms available at the time, but soon the quest mutated into designing a completely new tone arm and hold system.
The result of this laborious task has enhanced the turntables potential immensely and is now incorporated into all Vestax
professional level turntables. The system breaks with ill foundered traditional tone arm logic in order to achieve a high level of
non skipping performance, especially during hard play (scratch). Essentially this system focuses on two very separate, yet very
important inventions. One is a short straight arm and the other is the way in which the arm is balanced, both vertically and
horizontally.
• TH (Tracing hold) Balance System. This system allows for both vertical and horizontal movement, which helps the balance of
the tone arm. When combined with a short straight tone arm the best stability ever is provided for the needle, which in turn
allows for hard play.
• The tone arm, both straight and short, is made up of two parts - an inner and an outer tube. The inner tube, brass, is housed
within an outer tube of aluminum, which reduces the effects of howling and also provides a more sensitive pick up. Compared
with other tone arms on the market, the A.S.T.S tone arm reduces howling by approximately 50% more.

The inside force is minimized. The tracking force (frictional force) generated between
the stylus and the record disc makes the inside force.
