Sideways Uni-Pivot Arm Torque Reaction Augments Contact
SUPATRAC is a new turntable tone arm with an evolved bearing design which outperforms traditional tone arms. A patent application is in progress.
Sideways Uni-Pivot Arm (SUPA)
Supatrac's sideways uni-pivot directly opposes stylus drag at a single point of contact, avoiding bearing chatter, slippage, and flex in the time axis.
Whatever the temperature, and however old your Supatrac bearing, it has no gap and does not rub during play. Supatrac's zero tolerance bearing is immune to heat, wear, and lubricant decay. Supatrac is designed not to deteriorate with age.
Despite the robustness of Supatrac's zero-tolerance bearing, if you want the peace of mind of factory-fresh parts, you can replace the pivot point in less than two minutes without dismantling your turntable.
Hot signals increase stylus drag, producing a torque around the pivot which increases downforce just when it's needed to abolish the bane of tone arms: mistracking. Supatrac tracks a little firmer when the going gets rough by increasing downforce during loud dynamics, eliminating the raspy sound of mistracking which has plagued vinyl playback for a century.
Time Axis Uni-Pivot
Supatrac is designed to be most rigid in the axis which matters most: the groove's time axis. It never misses a beat, never swallows a detail, and never collapses the raw energy of the musical signal. The single bearing point directly opposes the oscillating drag force on the cartridge so there's no slipping and no timing error in music retrieval.
Supatrac is designed to be lightweight and stable, fitting almost any turntable including classics like Linn, Technics, Garrard, Rega and many more. The arm suspension obstructs the azimuth swing which compromises normal uni-pivot arms, so Supatrac suits suspended turntables as well as free standing ones.
Supasound is aiming to have a production version of Supatrac in production within the next six months, at a price which puts other super-arms to shame.
