Once the arm is correctly balanced return it to the rest. Hold the counterweight (8) without moving it, and gently
revolve the downforce scale ring until the zero is in line with the anti-skating stub. Check whether the arm still
balances out.
Rotate the counterweight counter clockwise (seen from the front) to adjust the downforce according to the
cartridge manufacturer's recommendations. One mark on the scale represents 1 mN (= 0,1g / 0,1 Pond) of
the down-force.
Please note: Adjust the downforce prior to installing the anti-skating weight.
Anti-skating force adjustment
The anti-skating force must be adjusted corresponding to the downforce as follows:
Downforce
10 - 14mN
15 - 19mN
20mN and bigger
Hang the loop of the thread of the anti-skating weight in the groove of the anti-skating stub (15) corresponding
to the downforce applied to your cartridge and hang the thread in the groove of the wire support (14).
Adjusting the azimuth
The cartridge needle must be vertical in the record groove in order to trace the groove wall modulations
correctly.
A small screw at the bearing end of the arm allows incorrect azimuth to be corrected if your needle is not
mounted exactly perpendicular to the cartridge body (which is often the case).
Slacken off the screw just enough to be able to revolve the arm tube without applying force.
Note! Do not remove the screw completely!
With the aid of a good magnifying glass adjust the needle until it is vertical in the groove (i.e. perpendicular
to the record's surface). Ideally this should correspond to the top surface of the cartridge body being parallel
to the record surface, but in practice this is often not the case.
When you are satisfied that the needle is vertical, retighten the screw carefully.
Please note: Under no circumstances should the arm tube be adjusted with the needle still in the record
groove! Irreparable damage may be caused to the cantilever suspension! The arm must be lifted to
make each adjustment and lowered afterwards to check it.
Adjusting the vertical tracking angle (VTA)
Put a record and the record weight on the platter. When the needle is lowered into the record groove and the
tonearm is not resting on the lift arm, the tube of the tonearm should be parallel to the surface of the record.
If it is not, loosen both allen screws in the tonearm base just enough to allow vertical movement of the arm
pillar without force and slide the arm up or down until it is parallel.
Carefully retighten the allen screws without applying excessive force (which would deform the arm pillar) –
finger tight is quite sufficient.
