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.

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.
Pushing carefully, turn the counterweight (7) onto the rear end of the tonearm tube (2), and so that the
downforce scale (7a) 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 (7) 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 (7) without moving it, and
gently revolve the downforce scale ring (7a) until the zero is in line with the anti-skating prong (8). 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. One mark on the scale represents 1 mN (= 0,1g / 0,1 Pond) of
downforce.
Tonearm Pro-Ject 9cc Evolution: The counterweights (7) supplied are suitable for cartridges weighing
between 5 - 7,5g, 7 - 10g, 9 - 11g or 10 - 14g.
Tonearm Pro-Ject 12cc Evolution: The counterweights (7) supplied are suitable for cartridges weighing
between 4 - 7g, 6 - 9g, 8 - 12g oder 10 - 15g.
Adjust the downforce prior to installing the anti-skating weight.

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
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. Note! Do not remove the screw completely!
Screw
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.
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 corresponding to the downforce as follows:
Downforce Groove in the stub (15)
10 - 14mN 1st from bearing rings
15 - 19mN 2nd " " "
20mN and bigger 3rd " " "

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 hang the thread in the groove of the wire support (17).
Adjusting the vertical tracking angle -vta-
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 tube (2) of the tonearm should be parallel to the surface of the record.
If it is not loosen both hexagon screws in the tonearm base (9) 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 screws without applying excessive force (which would deform the arm pillar)
– finger tight is quite sufficient.
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..

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.
