Adjusting the vertical tracing angle (vta)
The cartridge needle must be vertical in the record groove in order to trace the groove wall modulations correctly. A small screw at the bearing end of the arm, which is covered by the outer bearing ring, allows incorrect vta to be corrected if your needle is not mounted exactly perpendicular to the cartridge body (which is often the case). In order to access this screw, the stub for the anti-skating weight thread (15) must be removed by gently unscrewing it with flat nosed pliers or a strong pair of tweezers. Keep the stub in a safe place until you are ready to reinsert it. Now tilt the front of the tonearm up, and slacken off the screw just enough to be able to revolve the arm tube without applying force. Note! Do not remove the screw completely! With the aid of a good magnifying glass adjust the needle until it is vertical in the groove (i.e. perpendicular to the record's surface). Ideally this should correspond to the top surface of the cartridge body being parallel to the record surface, but in practice this is often not the case. When you are satisfied that the needle is vertical retighten the screw carefully and replace the anti-skating stub. Under no circumstances should the arm tube be adjusted with the needle still in the record groove! Irreparable damage may be caused to the cantilever suspension! The arm must be lifted to make each adjustment and lowered afterwards to check it.
Anti-skating force adjustment
The anti-skating force must be adjusted according to the mass of the cartridge as follows: Downforce 10 - 15 mN 15 - 20 mN 20 - 25 mN Groove in the stub (15) 1st from bearing rings 2nd 3

Hang the loop of the thread of the anti-skating weight in the groove of the anti-skating stub (15) corresponding to the downforce applied to your cartridge and feed the thread through the loop of the wire support (17). By applying gentle pressure to the wire support (17) bend it until the anti-skating weight hangs exactly over the spot shown on page 2. With very heavy cartridges it is possible that the anti-skating force will not be sufficient even in the third groove. A heavier anti-skating weight can then be ordered through your PRO-JECT dealer.
Changing replay speed
To play records at 45 r.p.m. first remove the platter (5). Using the accessory tool provided hook the belt (3) over the larger diameter part of the motor pulley (2). Refit the platter. To revert to 33,33 r.p.m. repeat the proceedings using the smaller step on the pulley.
Connection to the amplifier
The PRO-JECT 1.2 has a captive tonearm signal lead (14) for connection to the amplifier. Use the Phono input (sometimes labeled gram, disc or RIAA) on your amplifier. Make sure that the phono input offers correct matching and amplification for the type of cartridge used. Line inputs (such as CD, Tuner, Tape or Video) are not suitable. Take care to connect the left and right channels correctly. The right channel is usually marked red, the left channel black or white. Check the manual supplied with your amplifier for relevant information. The earthing wire of the tonearm lead should be connected to the earth terminal on your amplifier (if provided). If your amplifier does not have an input suitable for phono cartridges you will require a separate phono amplifier stage for MM or MC cartridges such as the PRO-JECT PHONO BOX, which is then connected between the record player and a free line level input of the amplifier.
