Tonearm And Cartridge System - THORENS TD 1500 Manuel D'utilisation

Tonearm and cartridge system

For the correct operation of the TD 1500, a few adjustments have to be made to the tonearm. The supplied
Ortofon 2M Bronze cartridge is pre-installed and does not need to be adjusted. First, the counterweight is
installed and then the tracking force and anti-skating are adjusted.
The counterweight of the tonearm has been packed separately for transport. For the correct adjustment of all
necessary values, please follow the steps listed below:
1. Screw the counterweight onto the back of the end of the tonearm (picture 7).
2. Slide the anti-skating adjustment weight (picture 8) in the arm base as far back as possible towards the
tonearm bearing.
3. Fold the lift lever forward so that the lift bench is lowered.
4. Remove the needle guard on the pick-up and loosen the tonearm lock.
5. Carefully move the tone arm towards the turntable with the finger lever so that it can swing freely up and
down. Make sure that the needle does not touch the platter or the chassis.
6. Turn the counterweight until the tone arm floats freely and swings back into a straight line by itself. If the
arm is up, turn the counterweight slightly counterclockwise, if it is down, turn it in the opposite direction
until it is balanced.
7. Put the tone arm back on the support and fix it.
8. On the counterweight there is a ring with a scale for the tracking force in Pond, which can be moved inde-
pendently of the weight. Now turn this ring alone, without turning the whole weight, until the 0 at the top is
opposite the mark on the bearing block of the tone arm.
9. To set the desired tracking force, now turn the counterweight as a whole until the corresponding number
is at the top. The Ortofon 2M Bronze cartridge supplied requires between 1.4 and 1.7 pounds of tracking
force. Recommendation 1.5 pond.
