Setting the tracking force (VTF)
Your tonearm features a unique mechanism for coupling the counterweight
to the rear end of the tonearm. A spring-loaded pin connects with the spiral-
groove and allows quick linear positioning as well as precise and backlash-
free adjsutment.
An engraved scale allows setting the vertical tracking force, even if you
don’t have a tonearm scale at hand.
Installing the counterweight
- Hold the counterweight (1) and move it to the rear end of the tonearm (2)
- Move the counterweight horizontally for approcimate setting
- Turn the counterweight clockwise to increase the VTF
- Turn the counterweight anticlockwise to decrease the VTF
Reset the scale
- Turn the counterweight until the tonearm is in fully balanced position
- Hold the main-unit (3) of the counterweight in place
- Turn the scale (4) until the 0-Position is aligned with the marking (5)
Setting the VTF
Turn the counterweight until the wanted value for the VTF is aligned with
the marking (5). The scale shows the value in dg: 10dg = 1g.
Note
The accuracy of the integrated scale is limited to ±0,1g. For more precise
adjustment, please use a separate tonearm scale.

Setting the Vertical Position
For precise adjustment of the vertical tracking angle, your tonearm features
a mechanism to set the vertical position.
Correct setting is achieved when the tonearm is in absolute horizontal
position while the stylus is tracking a record-groove. To compensate for
tolerances of your cartridge, minor deviation from the horizontal position
could be required. Please ask your dealer for further information.
1. Use the 2mm Hex key wrench to release the retaining-screw (1) for
half a turn.
2. Adjsut the vertical position
- Turn the VTA-Ring (2) clockwise to increase the height
- Turn the VTA-Ring (2) anticlockwise to decrease height
3. Tighten the retaining-screw (1) again.
Gently tighten the VTA-Ring (2) towards the Base-Ring (3).

Anti-Skating Device
Your tonearm features a contactless magnetic skating compensation
device. The compensation force can be adjusted continously from minimum
(1) to maximum (5).
Anti Skating Setting
Turn the dial to set the desired compensation force. As a general rule, the
value on the dial should refer to the vertical tracking force (VTF).
Note
The skating-force is not a constant value. It depends on:
a) the vertical tracking force
b) the stylus shape
c) the groove modulation
A blank disk can help to set the compensation force. However, in certain
cases, the procedure may be unsuitable, especially with modern stylus
shape such as Super-Fine-Line or Multi-Radius.
In such cases, we recommend to keep the setting between 2 and 3. For
further information, please contact your dealer.
