SETUP

Platter and drive belt installation

Please remove brown paper insert which holds the platter in transport position. Put the felt mat on the top of the platter. Install the drive belt as shown in the following illustration.

Cartridge installation, stylus exchange
  • If you purchased this turntable in a package that included the cartridge, this has already been done for you. Install the cartridge into the aluminum headshell, using the appropriate hardware included with your cartridge. All cartridges with half inch mounting holes can be fitted. Connect the cartridge as indicated below:

    • White           left channel L+
    • Red              right channel R+
    • Green          right channel R-
    • Blue             left channel L

For correct cartridge alignment, use the two-point cartridge alignment protractor provided with your Essential III accessories. If unfamiliar with two-point setup, please refer to your dealer. A damaged or worn stylus may harm your record collection and should be replaced. Please remove stylus protection before pulling the stylus from the cartridge and replace for a new one. Stylus type is exchange for pre-mounted cartridge Ortofon OM 10: Stylus OM 10. If in doubt, consult your local dealer or distributor.

Vertical Tracking Force setting (VTF)

Before setting the Vertical Tracking Force, confirm the exact weight of your cartridge. The counterweight supplied (no. 00 ) is suitable for cartridges from 3,5 to 5,5g. An alternative counterweight (no. 01 ) for cartridges between 6 – 9g is available on request. Pushing carefully, turn the counterweight onto the rear end of the tonearm tube. With the tonearm lift in lower position, carefully rotate the counterweight until the tonearm tube balances out. Once the tonearm is correctly balanced, return it to the rest. Hold the counterweight without moving it, and gently revolve the downforce scale ring until the zero is in line with the anti-skating stub. 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. Please note: Adjust the VTF prior to installing the anti-skating weight.

Anti-skating force adjustment

Hang the loop of the thread of the anti-skating weight in the groove of the anti-skating stub corresponding to the downforce applied to your cartridge and feed the thread through the loop of the wire support. The anti-skating force must be adjusted corresponding to the downforce as follows:

VTF Groove in the stub
10 – 14mN 1st  from bearing rings
15 – 19mN 2nd    ”          ”          “
20mN and bigger 3rd    ”          ”          “
Azimuth setting

The cartridge needle must be perpendicular to the record in order to trace the groove wall modulations correctly. The azimuth (angle) is precisely set by the factory. In the event that you need to modify this setting, however, follow the instructions below. Loosen the small azimuth screw, again using the 1.5 mm allen key.

DO NOT REMOVE THE AZIMUTH SET SCREW COMPLETELY!

Loosen the screw just enough to be able to gently rotate the arm tube and set the azimuth to the correct position. The correct position can be checked from the front view, preferably with the needle placed on a mirror placed on the platter. Once the azimuth setting is correct, gently re-tighten the azimuth setting screw.

Potential incorrect use and fault conditions

Pro-Ject turntables are manufactured to the highest standards and undergo strict quality controls before leaving the factory. Faults that may possibly occur are not necessarily due to material or production faults but can sometimes be caused by incorrect use or unfortunate circumstances. Therefore the following list of common fault symptoms is included.

The platter doesn’t turn although the unit is switched on:


The unit is not connected to the mains power supply. No mains at the socket. Drive belt is not fitted or has slipped off

No signal through one or other channel or both channels:


No signal contact from the cartridge to the internal tonearm wiring or from that to the arm lead or from that to the phono box or between that and the amplifier. This could be due to a faulty plug, broken wire or solder joint or simply loose plug/socket connection. Phono input not selected at amplifier. Amplifier is not switched on. Amplifier or speakers are defective or muted. No connection to the loudspeakers

Strong hum on phono input:

No earth connection from cartridge or arm or arm cable to amplifier, or earth loop.

Distorted or inconsistent sound from one or both channels:
Record player is connected to wrong input of amplifier, or MM/MC switch incorrectly set. Needle or cantilever damaged. Wrong r.p.m., drive belt overstretched or dirty, platter bearing without oil, dirty or damaged.
