Installing and Aligning the Cartridge
• For cartridges with threaded mounting holes, use the screws supplied by the cartridge
manufacturer. Other screws may not fit properly and may cause damage to the threads and
cartridge.
• To avoid damage to the 3D tonearm, use the provided finger lift which also serves as a washer
supplied by VPI under the screw heads and do not tighten the screws too tight.
• For cartridges with pass-through mounting holes, use the hardware supplied with the tonearm.
Be sure to use washers under the screw heads.
• The tonearm wires are colour-coded as follows:
Red tag right hot/+
Green tag right ground/-
White or Black tag left hot/+
Blue tag left ground/-
If your phono section inverts phase, the hot colour becomes the ground colour. In
this case please seek support from you VPI retailer
• Using tweezers or fine-tipped pliers, grip the centre of the red wire’s connector tag not the wire
itself and push it onto the cartridge’s right hot/+ terminal pin. Connect the remaining connectors
in the same way. To avoid damage to the cartridge, do not push the connectors all the way on.
• Place the Alignment Jig on the spindle with the V-groove against the base of the arm bearing
shaft. Tighten the screws of the jig so it fits snugly against the bearing shaft and over the record
spindle.
The arm should be placed in the arm rest when you are not playing a record!
• Line up the red dot on the Lemo connector with the red dot on the receptacle on the junction
box. The Lemo connector can plug in only one way and should not be forced.
