Replacing the Stylus

Replacing the Stylus

The AT-PL120 comes supplied with a high-quality 
Audio-Technica ATP-2 cartridge. The stylus should be 
replaced with a genuine Audio-Technica ATP-N2 stylus.

1.

Release the headshell assembly from the tone arm by 
turning the locking ring clockwise.

2.

Carefully remove the headshell assembly and turn it over 
so the stylus is visible.

3.

Remove the stylus assembly by pulling it away from the 
cartridge body at a slight angle. [See Figure 7.]

4.

Remove the replacement stylus from its package and 
carefully align it with the cartridge body.

5.

Gently push the stylus onto the cartridge body, being 
careful not to damage the stylus. The stylus assembly 
should click into place.

6.

Replace the headshell assembly on the tone arm and 
secure with the locking ring.

Figure 7 Removing the Stylus

Replacing the Cartridge

Mechanical Assembly 

1.

To replace the cartridge, first release the headshell 
assembly from the tone arm by turning the locking ring 
clockwise. Carefully remove the headshell assembly and 
turn it over so that the stylus is visible. Remove the stylus 
assembly by pulling it away from the cartridge body at a 
slight angle. [See Figure 7.] Place the stylus assembly out
of harm’s way.

2.

Remove the cartridge body by loosening the two small 
screws securing the cartridge to the headshell. Set the 
hardware aside to be reused with the new cartridge.

3.

Unpack the new cartridge and carefully remove its stylus 
assembly. Place the stylus assembly out of harm’s way. 
Mount the new cartridge to the headshell assembly. Use 
the mounting hardware supplied with the new cartridge or 
the existing hardware removed at step 2. Tighten the 
mounting screws until just snug. Replace the stylus 
assembly briefly to check for mechanical interference with 
the mounting hardware. The stylus assembly should click 
into place. Make certain the new cartridge is properly 
positioned in the headcase assembly per the 
manufacturer’s instructions. Again remove the stylus 
assembly for safekeeping.

Electrical Connections

1.

Four terminals at the rear of the cartridge are color coded 
to match standard wiring in stereo tone arms. [See Figure 
8.] Connect the cartridge with the slip-on lugs provided on 
the headshell wiring. NEVER SOLDER TO CARTRIDGE 
TERMINALS! Heat applied to the terminals will damage 
the internal cartridge wiring.

2.

For monaural operation, the left and right signal leads 
should be connected to the monaural output terminal and 
the left and right ground leads should be connected to the 
ground terminal. 

3.

Finally, gently push the stylus onto the cartridge body being 
careful not to damage the stylus. The stylus assembly 
should click into place. Replace the headshell assembly 
onto the tone arm taking care not to damage the stylus 
assembly.

(Note: After replacing the cartridge, reset the tone arm balance,
stylus force and anti-skate based on the new cartridge’s 
specifications.)
