recommended optimum tracking force setting is given for each model in the specification section of this manual.
Anti-Skate/Bias: Due to the rotational inertia of pivoted tonearms, the friction of the stylus on the record groove
produces a force pulling the stylus toward the center of the record. Anti-Skate (or mechanical bias) is added to
compensate for this force in order to equalize the stylus tracking on the sides of the groove walls. Because this is a
dynamic force, do not attempt adjustment using a blank or grooveless record, as this will result in over compensation.
When using a Sumiko Oyster™ moving magnet cartridge (Oyster™, Black Pearl™ or Pearl™), a value equal to the
tracking force should be applied.
Because anti-skate is based on the mass and compliance of the cartridge design, the amount applied can be quite
a bit different for the varying designs available. The Oyster™ Series moving coil cartridges (Blue Point No. 2 and
Blue Point Special EVO III) are lower compliance and higher mass designs and are less affected by the vector force
