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.
The record player is supplied with a factory fitted and adjusted cartridge.
** The following instructions for adjusting the cartridge are provided in case the cartridge is replaced by a
different model at a later date.
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 three feet (22) 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 the supplied spirit level) before placing the turntable on it.
Carefully insert the spindle into the bearing. Put the record weight on the platter and level the plinth using the
supplied spirit level and the adjustable feet (23).
Assemble motor and motor base. Place the motor unit to the left of the turntable. Position the motor unit with
the aid of the supplied template. Fit the drive belt (3) around the platter (5) 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.
Remove the transport lock (18) from the tonearm. Store it in the original packaging so they are available for
any future transportation.
Cartridge downforce adjustment
Counterweigts supplied: SuperPack 1 with Ortofon Rondo Red - for cartridges weighing between 8 - 11g.
SuperPack 2 with Sumiko Blue Point No. 2 - for cartridges weighing between 6 - 10g.
Counterweigts optional: SuperPack 1 with Ortofon Rondo Red - for cartridges weighing between 11 - 15g,
6 - 10g or 5 - 8g. SuperPack 2 Sumiko Blue Point No. 2 - for cartridges weighing between 11 - 15g, 8 - 11g
or 5 - 8g. Adjust the downforce prior to installing the anti-skating weight.
Pushing carefully, turn the counterweight (6) onto the rear end of the tonearm tube (9), and 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. This adjustment must be done
carefully. Do not forget to remove the cartridge protection cap if fitted.
Once the arm is correctly balanced return it to the rest. Hold the counterweight (6) without moving it, and gently
revolve the downforce scale ring (6a) until the zero is in line with the anti-skating prong (15). 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.
The recommended downforce for the Ortofon Rondo Red cartridge is 23mN.
The recommended downforce for the Sumiko Blue Point No. 2 cartridge is 18mN.
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
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. Please 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.
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 according to the mass of the cartridge 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 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. Your dealer can advise you on
alternative cables. 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. 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.
The recommended load resistance for the Ortofon MC Rondo Red cartridge is: 10-200ohms/MC-input.
The recommended load resistance for the Sumiko Blue Point No. 2 cartridge is: 47kohms/MM-input.
Connection the Speed Box SE, 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 Intput ~16V socket on the Speed Box SE.
Connect the power cable supplied to the Output ~16V socket on the Speed Box SE and to the record
player's motor unit (13) before connecting the power supply to the mains.
Switching on and off
Pressing the power switch (20) alternately starts or stops the motor.

Fitting the optional lid
Fit the lid carefully on to the record player from above.
Maintenance and cleaning
Your record player requires little or no regular maintenance. Remove dust with a slightly moistened antistatic
cloth. Never use a dry cloth because this will create static electricity which attract more dust! Antistatic
cleaning fluids are available at specialist stores but must be applied sparingly to avoid damage to rubber
parts. 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 lid (optional) is not only a dust cover but also a resonant structure likely to be excited by, and to pass into
the plinth, the acoustic energy emanating from your loudspeakers during replay. It is therefore recommended
that the lid be removed for optimum sound quality.
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.

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). 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.

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:
