[. . . ] Store it together with the two red motor transport screws (1) in the original packaging so they are available for any future transportation. Fitting and connecting the cartridge All cartridges with half inch mounting holes can be fitted. Leaving the needle's protection cover on, fit the cartridge to the headshell using the screws supplied with the cartridge by passing one screw through each slot in the headshell (21). Connect the tonearm wires to the cartridge pins as follows: white left channel positive (L+) red right channel pos. [. . . ] 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. 4 © Audio Trade GmbH · Pro-Ject RPM 6. 1 SB · Revision 1. 3. 08/1. 5. 08 Adjusting the vertical tracking angle (vta) Put a record and the record weight on the platter. When the needle is lowered into the record groove and the tonearm is not resting on the lift arm, the tube of the tonearm should be parallel to the surface of the record. If it is not loosen both allen screws in the tonearm base just enough to allow vertical movement of the arm pillar without force and slide the arm up or down until it is parallel. Carefully retighten the allen screws without applying excessive force (which would deform the arm pillar) ­ finger tight is quite sufficient. Adjusting the azimuth 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 allows incorrect azimuth to be Screw corrected if your needle is not mounted exactly perpendicular to the cartridge body (which is often the case). Slacken off the screw just enough to be able to revolve the arm tube without applying force. With the aid of a good magnifying glass adjust the needle until it is vertical in the groove (i. e. Ideally this should correspond to the top surface of the cartridge body being parallel to the record surface. When you are satisfied that the needle is vertical retighten the screw carefully. Under no circumstances should the arm tube be adjusted with the needle still in the record groove!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 Groove in the stub (15) 10 - 14mN 1st from bearing rings 15 - 19mN 2nd " " " rd 20mN and bigger 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). Connection to the amplifier The record player has gold plated female RCA phono sockets (14) so you can substitute the interconnect cables supplied with those of your choice for connection to the amplifier if you wish. Use the Phono input (sometimes labelled gram, disc or RIAA) on your amplifier. Make sure that the phono input offers correct matching and amplification for the type of cartridge used. The right channel is usually marked red, the left channel black or white. Check the manual supplied with your amplifier for relevant information. An earthing wire may be connected to the screw terminal between the sockets if you encounter hum problems when using the record player. 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 or the PRO-JECT TUBE BOX which is then connected between the record player and a free line level input of the amplifier.
