Cartridge downforce adjustment (Pro-Ject Evolution tonearms)
Remove the transport lock (3) from the tonearm. Store it in the original packaging so they are available for
any future transportation.
Pushing carefully, turn the counterweight (7) onto the rear end of the tonearm tube (2), and so that the
downforce scale (7a) 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 (7) until the armtube balances out.
The arm should return to the balanced position if it is moved up or down. Do not forget to remove the
cartridge protection cap if fitted.
Once the arm is correctly balanced return it to the rest (3). Hold the counterweight (7) without moving it, and
gently revolve the downforce scale ring (7a) until the zero is in line with the anti-skating prong (8). 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.
