Dear music lover,
Thank you for purchasing your Debut PRO B.
Since 1991 we have been offering high-quality hi-fi products at a reasonable
price for discerning music lovers. We started with turntables because they are
the first choice for the most natural and affordable music reproduction. Our
main focus is always on the materials and technology used. The shape and
design of our turntables are always dictated by the functionality.
To this day, our designs have always been kept functional and clean, so the
first Pro-Ject product was very simple but made from the highest quality
materials: MDF, steel, aluminium, glass, and carbon. Plastic was not used for
reasons of sound, durability, and the love of the environment.
The result was a high-quality but simple-looking product with great sound at a
low price.
After the Debut Carbon EVO revolutionized the Debut series in 2020, the Debut
PRO raised the bar even higher. Now, the Debut PRO B revision also features a
balanced mini XLR output together with our new Pick it PRO Balanced cartridge.
The first ever balanced MM cartridge!
In order to achieve maximum performance and reliability with new Debut PRO B
please read this guide carefully!
Warning of a hazard for the user, the unit or possible misuse.
Important notice.
Safety instructions
The power supply is used to connect and disconnect the unit from the mains.
Make sure that the plug is easily accessible at all times. Hold the plug when
unplugging the power cord. Never handle the power cord while your hands are
wet or damp.
Avoid letting liquids enter the device. Never place any item containing
liquid, like a flower vase, on or near the device. Never spill any liquid on
the device. Never place any naked flame sources, like lighted candles, on or
near the device. The product shall not be used in damp or wet locations, next
to a bathtub, sink, swimming pool or any other similar conditions.
Keep plastic bags away from children to prevent any risk of suffocation.
First Set-up – Making your Debut PRO B ready for playback
The deck is supplied partially disassembled and carefully packaged for safe
transport. The Setup Guide, included in the packaging with your Debut PRO B,
explains the setup process step by step with pictures, so be sure to follow it
first and then refer to this guide should you want more detailed explanations.
Here, some of the more technical set-up steps are covered in detail and you
will gain a lot of important background information which will make you more
comfortable with everything your new Debut PRO B has to offer.
Positioning and levelling your turntable
Make sure the surface you wish to use the turntable on is level (use a spirit
level) before placing the turntable on it. The height adjustable aluminium
feet (19) on the Debut PRO B will also allow you to level the turntable
itself, in case you cannot get the surface it is placed on to be level. Great
surfaces to put your record player on are typically massive, heavy, stable and
also as far as possible away from your speakers. This will avoid the sound of
footsteps and other low frequency rumble noises to be transmitted via your
floor and furniture/surface and picked up by your turntable. If your record
player is super close to your speakers and/or placed on the same surface as
your speakers are, then the sound from your speakers will be picked up by your
turntable over the sound pressure waves in the air and vibrations from
speakers to the surface. It will be a great idea to decouple the speakers from
the surface (for example with our Damp it) and/or get a really heavy, massive
and decoupled surface for your turntable (for example our Ground it range of
accessories). Different locations/rooms/set-up places have different
requirements and if you think you might be running into troubles with your
set-up, definitely do check these upgrades out, so your Debut PRO B can unfold
all of its performance.
Cartridge tracking force adjustment (VTF = vertical tracking force)
The counterweight (6) supplied is suitable for cartridges weighing between
7 – 10.5g (Pro-Ject Pick it PRO Balanced – weight no. 58).
When using different cartridges than the ones supplied with the Debut PRO B,
confirm the exact weight of your cartridge before you set the VTF.
Pushing carefully, move the counterweight (6) onto the rear end of the
counterweight support rod as shown in the picture below.
Place the stylus pressure gauge onto the platter. To set the required VTF,
lower the tonearm lift lever as indicated in the illustrat on and place the
tip of the stylus exactly in the point marked 20mN (20mN = 2g). If the stylus
gauge becomes level, then the correct pressure has been achieved. However, if
the there is insufficient or excessive pressure the gauge will either not move
or tilt down.
Please note: Adjust the tracking force prior to installing the anti-skating
weight.
To adjust the amount of pressure, carefully move the counterweight (6) along
the support rod, until the stylus pressure is sufficient to raise the pressure
gauge to the level position. Moving the counterweight (6) away from the
cartridge will reduce pressure and towards will increase pressure.
The recommended tracking force for the Pro-Ject Pick IT PRO Balanced cartridge
is 20 mN = 2g. Use electronic tracking force scales (like Measure it E) for
more accurate results.
Anti-skating force adjustment
The anti-skating force must be adjusted corresponding to the downforce as
follows:
| Downforce | Groove in the stub (18) |
|---|---|
| 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).
The Pick it PRO Balanced cartridge on your new Debut PRO B has a recommended
tracking force of 20mN (2 grams) so the correct groove for the anti-skating is
the 3rd groove.
Connection to an amplifier (integrated amplifier or phono preamplifier)
The record player has gold plated female RCA Phono sockets (14) on the
back. Use the included Connect it E phono RCA cable to connect your Debut PRO
B to your amplifier. The cable ends with the yellow markings are plugged into
the phono inputs sometimes also 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.
The recommended load impedance for the Pick it PRO Balanced is: 47 kohms
The recommended load capacitance for the Pick it PRO Balanced is: 150 – 300 pF
Check your amplifier documentation!
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 your amplifier does not have an input suitable for phono cartridges you
will require a separate phono amplifier stage for MM cartridges which is then
connected between the record player and a free line level input of the
amplifier. A separate phono preamplifier can also be helpful if you want to
upgrade your sound experience, as external phono preamps are 100% dedicated to
making your turntable sound as good as it can possibly be. They are not
limited by other restrictions typically found in integrated amplifiers, which
are almost always compromising sound quality a bit.
If you have a balanced phono preamplifier (like our Phono Box S3 B) you can
use your Debut PRO B’s full potential by running it in a true balanced
configuration. With a separately available Connect it Phono E RCA/miniXLR you
can connect your Debut PRO B to balanced phono preamplifiers and use your
cartridge’s full potential. Usually this is only possible with MC cartridges,
as typical MM cartridges cannot be ran in a fully balanced configuration. The
Pick it PRO Balanced is the first MM cartridge of its kind, specifically
modified to be compatible with balanced phono preamplifiers!
For detailed product information regarding Pro-Ject Audio interconnect cables
and phono amplifiers please refer to the Pro-Ject web site www.project-
audio.com.
Mains power connection
The turntable is supplied with the universal power supply with 3
exchangeable sockets adapters suitable for all countries. Select the correct
adapter for your country and insert the adapter to the exchangeable part of
the power supply.
Connect the low voltage plug from the power supply to the socket (15) on the
rear of the record player before connecting the power supply to the mains.
6. Fitting the lid
Fit the lid (dust cover 11) carefully over the hinge prongs and adjust the
screws (13) until the lid stays open where you want it to without being too
stiff to open or close.
The lid 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. Therefore, it is recommended to remove the lid
completely during vinyl playback for achieving a better sound quality.
Switching on and off, changing replay speed
The turntable is equipped with a rocker switch for electronic speed change. To
play records at 33 rpm, move the rocker switch to the left side. To play
records at 45 rpm, move the rocker switch to the right side. To be able to
play 78 rpm the flat drive belt has to be removed and the round drive belt has
to be fitted around the sub-platter (4) and the larger diameter part of the
motor pulley (2). To do so, the platter (5) has to be removed.
After the round drive belt has been fitted, moving the rocker switch to the
right selects 78 rpm.
Advanced Debut PRO B adjustment options
The following adjustments are NOT necessary for first time set-up but
important later on when changing or upgrading the cartridge! For the included
cartridge these settings are factory set correctly.
Adjusting the azimuth
The cartridge needle must be vertical in the record groove in order to
trace the groove wall modulations correctly.
The cartridge on your Debut PRO B that comes pre-adjusted by the factory, is
already correctly set up and you do not need to adjust the azimuth anymore!
You should check and/or re-adjust the azimuth if you change or upgrade your
cartridge.
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!
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. Please note : 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.
Fitting and connecting a cartridge
The following instructions for fitting and connecting a cartridge are
provided in case the cartridge is replaced by a different model at a later
date, the included cartridge comes fully adjusted and aligned from the
factory.
** 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 (20). 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. Refer to
the documentation of the alignment tools you are using for setting up your
cartridge correctly. Leave this work to your dealer if you are in any way
unsure of the necessary steps and precautions to be taken.
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 lift arm, the tube of the tonearm
should be parallel to the surface of the record.
If it is not, loosen both hexagon 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.
Retighten the hexagon screws without applying excessive force (which would
deform the arm pillar) – finger tight is quite sufficient. 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.
The platter bearing is important for the correct speed and overall lifetime of
the turntable. The oil can disappear by playing regularly or it gets dirty by
rubbing of the metal (turns from grey to black). You should continually check
if there is oil on the axle. In any case, it is a good idea to renew the
lubrication after 3 years at the latest.
We recommend using Lube it to lubricate your platter bearing.
Always disconnect the record player from the mains power supply as a
precaution before maintenance!

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 not switched on.
Amplifier or speakers 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.
