Cartridge Downforce Adjustment; Anti-Skating Force Adjustment - Pro-Ject Audio Systems X1 Instructions For Use Manual

4.

CARTRIDGE DOWNFORCE ADJUSTMENT

The counterweight (8) supplied is suitable for cartridges weighing between 7 - 10g (counterweight no. 46).
Adjust the downforce prior to setting the anti-skating force.
Place counterweight (8) halfway along the counterweight support rod at rear of arm, so that the downforce
scale shows towards the front of the player. Lower the armlift and position the cartridge in the space between
arm rest and platter. Carefully rotate the counterweight (8) until the armtube balances out. The arm should
return to the balanced position if it is moved up or down. This adjustment must be done carefully. Do not forget
to remove the cartridge protection cap if fitted.
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 prong. 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
downforce.
The recommended downforce for the factory fitted cartridge is 18mN.
