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.
** Your turntable has been delivered with a factory fitted and adjusted cartridge, please ignore the
cartridge set up instructions unless changing the cartridge 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
Make sure the surface you wish to use the turntable on is level (use a spirit level) before placing the turntable on it.
Remove the two red transport screws (1) which secure the motor (22) during transportation.
Remove the transport lock (18) from the tonearm. Store it together with the two red motor transport screws
(1) in the original packaging so they are available for any future transportation.
Fit the drive belt (3) around the hub (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. Fit the
platter (5) and felt mat over the spindle of the hub (4).

Cartridge downforce adjustment
The counterweight (6) supplied is suitable for cartridges weighing between 3,5 - 5,5g. Alternative
counterweights for cartridges weighing between 6 - 9g or 1,5 - 3g are available as accessory parts. 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 factory fitted cartridge is 17,5mN.
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 " " "
Slip the loop of the anti-skating weight's thread over the third groove of the stub to set the correct anti-skating
force for the factory-fitted cartridge. Feed the thread through the loop of the wire support (17).
Connection to the amplifier
The record player has a captive tonearm signal lead (14) for connection to the amplifier. Use a line input (such as
AUX, CD, Tuner, Tape or Video) on your amplifier.
!
Due to the built in phono pre-amplifier, a phono input (sometimes labelled gram, disc or RIAA) is 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. The earthing
wire of the tonearm lead should be connected to the earth terminal on your amplifier (if provided).
The 3,5 mm connector (supplied) can be used to connect your Pro-Ject Debut III/Phono SB to any line
level/auxiliary input (Computer, Midi System, Mixer etc.).
Connect the socket end to the phono plugs at the end of the audio trailing lead from your turntable and
insert the 3,5 mm plug into the relevant socket on your audio component.
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 (13) on the rear of the record player before
connecting the power supply to the mains.
Fitting the lid
Fit the lid (dust cover 10) carefully over the hinge prongs and adjust the screws (12) until the lid stays open
where you want it to without being too stiff to open or close.

Switching on and off
Pressing the power switch (20) alternately starts or stops the motor.
Changing replay speed
Press the speed change button (24) to switch between 33 and 45 r.p.m.. The selected speed is shown
respectively by the lit green LED (33 r.p.m.) or red LED (45 or 78 r.p.m.).
To replay records at 78 r.p.m. perform the following steps: Remove the platter (5) and using the tool (3a)
from the accessory kit. Fit the belt (3) around the larger diameter step of the pulley (2). Replace the Platter,
start the turntable at 33 r.p.m. and switch the speed to 45 r.p.m., the platter will then revolve at 78 r.p.m..
To play at 45 or 78 r.p.m. please always start the turntable at 33 r.p.m. and then switch to the higher speed
when it has attained full speed.
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 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.
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. 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.

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.
