Dear music lover,

thank you for purchasing a PRO-JECT AUDIO record player.

In order to achieve maximum performance and reliability with this record player you should study these instructions

for use carefully.

Warning of a hazard for the user, the unit or possible misuse.

Important notice.

During assembly and adjustment of the deck small parts could be lost if not carefully placed in a suitable

receptacle.

Before starting assembly make yourself acquainted with the parts listed above and correspondingly numbered

in the technical drawings above. Separately packed items are marked with an asterisk *.

Set-up

Screw the four feet (7) onto the threaded bolts located on the underside of the plinth. Make sure the surface

you wish to use the turntable on is level (use a spirit level) before placing the turntable on it.

Carefully place the platter bearing housing over the bearing axle. Put the record weight on the platter and

level the plinth using the spirit level (6a) and the adjustable feet (7).

Fit the drive belt (3) around the platter (4) and the smaller diameter part of the motor pulley (2).

Avoid getting sweat or grease on the belt as these will deteriorate the performance and reduce the belt's

lifespan. Use absorbent kitchen paper to remove any oil or grease from the outer edge of the hub and the belt.

Put the pulley cover on its rests.

Ortofon RS tonearms

Cartridge downforce adjustment

Remove the transport lock (3) from the tonearm. Store it in the original packaging so they are available for

any future transportation. Set the knob (5) to 0.

Place the counterweight (7) halfway along the counterweight support rod at rear of arm, being sure to have

the counterweights (7) securing screw uppermost. Lower the armlift and position the cartridge in the space

between tonearm rest (3) and platter. Carefully move the counterweight (7) along the support rod, until the

armtube (2) balances out. The arm should return to the balanced position if it is moved up or down. Do not

forget to remove the cartridge protection cap if fitted.

With the power off, and the platter static, place the supplied stylus pressure gauge onto the platter.

Carefully lower the armlift and position the tip of the stylus on the pressure gauges measuring tongue. The

downforce will be displayed digitally.

Adjust the Downforce, using the knob (6), to the cartridge manufacturer's recommendations. This adjustment

must be done with the tonearm resting on the tonearm rest (3). Finally secure the counterweight with the

securing screw (7).

The counterweight (7) supplied is suitable for cartridges weighing between 18 - 40g.

Anti-skating force adjustment (Ortofon RS and AS tonearms)

The anti-skating force must be adjusted corresponding to the downforce. Rotate the knob (5) to adjust the

Anti-skating force. One mark on the scale represents 5 mN (= 0,5g / 0,5 Pond) of downforce.

Adjusting the vertical tracking angle -vta- (Ortofon RS and AS tonearms)

Put a record on the platter. When the needle is lowered into the record groove and the tonearm is not resting on

the tonearm rest (3), the surface of the cartridge body should be parallel to the surface of the record.

If it is not loosen the hexagon screw in the tonearm base (8 RS tonearms or 7 AS tonearms) 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 hexagon screw without applying excessive force (which would deform the arm pillar) –

finger tight is quite sufficient.

Ortofon AS tonearms

Cartridge downforce adjustment

Remove the transport lock (3) from the tonearm. Store it in the original packaging so they are available for

any future transportation. Set the knob (5) to 0.

Pushing carefully, turn the counterweight (6) onto the rear end of the tonearm tube (2), so that the downforce

scale (6a) shows towards the front of the player. Lower the armlift and position the cartridge in the space

between arm rest and platter. Carefully rotate the counterweight (6) until the armtube balances out. The arm

should return to the balanced position if it is moved up or down. Do not forget to remove the cartridge

protection cap if fitted.

Once the arm is correctly balanced return it to the rest (3). Hold the counterweight (6) without moving it, and

gently revolve the downforce scale ring (6a) until the zero is in line with the black line at the rear end of the

tonearm tube (2). Check whether the arm still balances out.

Rotate the counterweight counter clockwise (seen from the front) to adjust the downforce according to the

cartridge manufacturer's recommendations.

The counterweight (6) supplied is suitable for cartridges weighing between 18 - 25g. An alternative weight

for cartridges weighing between 26 - 38g is available as an accessory part.

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 (1). Do not tighten the nuts yet.

Connect the tonearm wires to the cartridge pins as follows:

white left channel positive (L+)

red right channel pos. (R+)

green right channel return (R -)

blue left channel return (L -)

The full sound quality of the record player can only be achieved if the cartridge is correctly adjusted. Particular

tools like the PRO-JECT alignment tool are required to accomplish this job properly. If you are not well acquainted

with the adjustment of cartridges you are advised to call upon the willing help of your PRO-JECT dealer to

accomplish this task for you.

Please note: adjusting a cartridge and tonearm calls for the greatest care in order to avoid damaging

the cartridge or tonearm bearings. Leave this work to your dealer if you are in any way unsure of the

necessary steps and precautions to be taken.

Connection to the amplifier

Connect the tonearm cables to 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. 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. 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.

For detailed product information please refer to the Pro-Ject web site www.project-audio.com.

Mains power connection

The turntable is supplied with a power supply suitable for your country's mains supply. Check the label before

connecting to ensure compliance with the mains rating in your house.

Connect the low voltage plug from the power supply to the socket (1) on the rear of the record player before

connecting the power supply to the mains.

Fitting the lid

Fit the lid (dust cover 9) carefully over the hinge prongs and adjust the screws (8) until the lid stays open

where you want it to without being too stiff to open or close.

Starting the motor, Stand By

Pressing the button Speed Change will switch on the player from stand by. Press and hold the button Speed

Change to put the unit into stand by.

Changing replay speed

The belt must be on the smaller (50Hz models) larger (60Hz models) diameter part of the motor pulley.

Press the button Speed Change to switch between 33 and 45 r.p.m.. The selected speed will be displayed

digitally.

To replay records at 78 r.p.m. perform the following steps: Remove the pulley cover. Using the tool (3a), fit

the belt (3) around the larger (50Hz models, for 60Hz models the smaller diameter has to be used) diameter

step of the pulley (2). Start the turntable by pressing the button Speed Change and switch the speed to

45 r.p.m., the platter will then revolve at 78 r.p.m.. The display still shows 45 r.p.m..

Speed Change +

45.0

Pitch control

Repeatedly pressing the +or -buttons increases or decreases the replay speed in twenty steps of 0,1 r.p.m.

respectively. The adjusted speed is displayed digitally.

Maintenance and cleaning

Your record player requires little or no regular maintenance. Remove dust with the supplied antistatic cloth.

It is recommended to fit the needle cover before cleaning or maintenance is carried out to avoid damage.

If the player is not used over a long period of time the drive belt can be removed to prevent unequal stretching.

Always disconnect the record player from the mains power supply as a precaution before maintenance!

Useful tips

The base and the record player should be positioned on a low-resonance surface such as wood or multiple

layer ply board to avoid structural vibrations disturbing replay.

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.
