of the tonearm. Adjustments are made by simply loosening
the clamp screw and carefully sliding the entire tonearm up
or down. After the correct position for the VTA has been
found the clamp screw is tightened again and, well, that's all.
5. Azimuth adjustment
Azimuth means the exact perpendicular position of the sty-
lus in the record groove when viewed from the front. It
should be exactly 90° if the stylus has been meticulously
mounted onto the cantilever because otherwise it cannot
precisely track the records. As azimuth cannot be adjusted
with the TP 250 it is highly recommended to acquire only a
quality pick-up cartridge with precisely mounted stylus and
cantilever.
6. Adjusting overhang
and offset angle
Offset is the angle embracing the longitudinal axis of both
tonearm and cartridge. With all pivoted tonearms (like the
ones from THORENS) the optimum offset angle is to be
found between 21° and 24°. We recommend an offset
angle of 23°.
Overhang is the distance between stylus tip and centre of
the platter spindle. Usually, the overhang is defined bet-
ween 12 and 20 mm yet should be adjusted to 17 mm. For
this somewhat tricky work we advise to employ a special
pick-up alignment gauge. As there are still many varieties
commercially of such gauges available your THORENS dea-
ler may have some recommendations.
After finishing the cartridge set-up you should now tigh-
ten the headshell screws to fix the cartridge in the cor-
rect position.
