Adjusting horizontal zero (0) balance and stylus pressure
1. Without touching the stylus tip, remove the stylus protector (if your cartridge has a detachable one).
2. Release the arm clamp (10) and lift the tone arm (7) off the arm rest (11).
3. Counter clockwise advancement of the counterweight (8) will cause the cartridge side of the tone arm (7) to
be lowered; turning it clockwise will cause the opposite. Turn the counterweight (8) clockwise or counter clockwise
as needed until the tone arm (7) is balanced horizontally. You can easily tell this by watching for the point where the
tone arm (7) “floats” freely.
4. Place tone arm (7) on arm rest (11) and lock it in place with the arm clamp (10).
5. With the tone arm (7) locked on the arm rest (11), hold the counterweight (8) steady with one hand while
rotating the stylus pressure ring (9) until the numeral “0” on the ring aligns with the center line on the tone arm (7)
rear shaft. The horizontal zero (0) balance should be completed.
6. Re-float the tone arm (7) to ensure horizontal zero (0) balance. If zero balance has not been maintained, repeat
counterweight steps 3 - 5.
7. After adjusting the horizontal zero (0) balance, turn the balanced counterweight (8) counter clockwise until the
cartridge manufacturer’s recommend stylus pressure appears on the stylus pressure ring (9) where it meets the
center line of the tone arm (7) rear shaft.
Adjusting the anti-skating control
Set the anti-skating control (12) to the same value as the stylus pressure.
