Dear music lover,

Thank you for purchasing your Debut PRO.

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 raises the bar even

higher. We designed not only a new turntable, but also a completely new cartridge. Now, for the 30th

anniversary, we are again going back to our roots.

In order to achieve maximum performance and reliability with new Debut PRO 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 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, 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 has to offer.

PRO Info provides additional background information and insights into your Debut PRO and can be

skipped for the first setup. Read them later on if you want to know everything about your Debut PRO.

1. 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 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 can unfold all of its performance.

2. 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 -

weight no. 58).

When using different cartridges than the ones supplied with the Debut PRO, 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 illustration 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.

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.

Please note: Adjust the tracking force prior to installing the anti-skating weight.

The recommended tracking force for the Pro-Ject Pick IT PRO cartridge is 20 mN = 2g.

Use electronic tracking force scales (like Measure it E) for more accurate results.

PRO Info: Tracking Force

Cartridges usually have a tracking force range as stated by the manufacturer (for example 1.8 –2.2 grams).

The recommended tracking force is a result of the individual cartridge placed on the individual tonearm, the

record you play and the wear and age of your stylus. Just to name a few of the most important ones. You are

actually free to move within the range and divert from the recommendations. If your stylus is new you want to

ideally stay pretty much at the recommendation as a starting point. As it gets older (we are talking many,

many thousands of hours playtime) you can apply a little more tracking force. Other reasons why you want

more or less tracking force are old/dirty or badly worn records. Experimenting with a little more force might

enable you to extract more information out of a worn record groove (don’t worry about adding extra wear to

the record groove; the groove will wear if you are at 5g not if you are at 2.5g in our example here). If there

are scratches in the record or your record tends to skip, changing the tracking force a little higher or lower

might also enable you to play these records without skipping.

In general, it is true that if you move beyond the limits of the range as stated by the manufacturer you will

negatively affect the longevity of your stylus/cartridge and records. If you really know what you are doing it is

however possible to also use a little more tracking force beyond the range to get more tracking ability out of

your cartridge. Keep in mind as the tracking force gets higher and higher this will also affect the angle with

which the stylus lies in the record groove. Taking the tracking force to 2.4 grams, if the upper limit it 2.2

grams, you will also need to raise the height of the tonearm (also called the VTA –vertical tracking angle).

Obviously, we would only recommend this to experienced vinyl enthusiasts as correctly figuring out the VTA

setting requires a lot of experience in this case.

3. 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 cartridge on your new Debut PRO has a recommended tracking force of 20mN (2

grams) so the correct groove for the anti-skating is the 3rd groove.

PRO Info: Anti-skating

The anti-skating force counteracts the natural skating of your tonearm and cartridge towards the center of

your record. How strong this naturally occurring skating is, depends on a few factors such as the actual

physical properties of the record groove, where on the record your tonearm is currently sitting and playing

(the skating on the beginning/outside of the record is different than towards the end/inside of your record)

and the applied tracking force to name a few of the more important factors. The anti-skating mechanism on

your Debut PRO (and other Pro-Ject Audio Systems turntables) is able to vary the applied anti-skating force,

depending on whether the tonearm is on the outside or inside of your record. A lot of other common

implementations, like spring or magnet-based anti-skating mechanisms, are not able to vary the applied

force based on arm position.

There are a few popular ways to measure the anti-skating force and a few totally wrong ones. Totally wrong

would be to use a CD, turn the turntable on and think that anti-skating is set correctly when the tonearm will

stay in its place and not move at all. The groove of a vinyl record will generate different levels of friction for

the tonearm and is not comparable to a CD at all. Please don’t measure the anti-skating force with a CD.

The next better option is to use a test record that is made of actual vinyl. The result of the test record can

vary, so please be sure you know exactly what your test record is doing and interpret the results correctly.

The best way to measure anti-skating is a test record with actual music and test tones and dedicated

professional audio and test equipment to measure the actual channel balance and a whole range of other

attributes. The anti-skating mechanism of your Debut PRO turntable has been designed with this process. If

you are interested in checking anti-skating for yourself, please feel free to buy test records or even use a CD

just for the fun of it, but please also keep in mind that you will not achieve the best and accurate results like

this, so please treat them with a grain of salt.

Correctly set anti-skating will positively affect the left/right balance, the tracking of the record groove

(distortion, frequency response, dynamics) and minimize the wear of record and stylus.

4. 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 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 is: 47 kohms

The recommended load capacitance for the Pick it PRO 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.

PRO Info: Phono Cable

The included Connect it E phono cable is a semi-balanced phono interconnect cable purpose-engineered

for best-in-class turntable performance. It is terminated with high-conductivity RCA connectors for a tight fit

that won’t come loose when you move your equipment. They’re 24k gold plated for optimum signal transfer

and corrosion resistance. The Connect it E cable is a parallel symmetrical cable where the shield is only

connected on one end. The yellow mark indicates this side. The marked side should always be connected to

the receiving end (i.e. phono stage or amplifier). It is pretty rare to find a cable of these high specifications

included with turntables, but they are absolutely necessary and so critical for phono performance, which is

why Pro-Ject Audio Systems is including them by default. There is no way you can do it without specialised

cables like that. If you wish, you can further substitute the supplied Connect it E with even higher quality cables

such as the separately available Pro-Ject Connect IT C, CC or Si.

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.

5. 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.

PRO Info: Power Supply Upgrade

Your Debut PRO already has a speed control unit built in which at the same time already acts as a clean power

supply. The exact voltage and frequency for the motor are generated by this speed control unit, resulting in the

most accurate playback speeds. Upgrade power supplies (like the High Power it or Power Box DS2 Sources)

provide proper grounding and dramatically reduce ground hum of „floating mass“ systems/amplifiers.

Every turntable needs proper grounding, otherwise electrical hum may be induced. If a turntable is not properly

grounded, it may have a different reference potential than the connected amplifier. Consequently, these

potential differences induce a compensating current which can be heard as hum. Therefore, all good turntables

have a separate ground cable which can be connected to standard amplifiers or phono stages, which usually

have a ground terminal. This way different potentials are equalized and hum is no longer audible. However,

many modern amps, especially most amps of soundbars or streaming speakers have no ground connection.

These systems are referenced as “floating mass systems“. If a standard turntable is connected to such a

„floating mass“ amplifier, audible hum will be the result.

The Power Box DS2 Sources is also a true linear power supply with a big toroidal transformer and will power

other Pro-Ject Audio Systems Box Design HiFi electronics as well.

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.

7. 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.

PRO Info: Electronic Speed Control

The speed is electronically controlled with precision motor control unit which guarantees the most accurate

and stable speeds. Each motor runs at a certain voltage and frequency. The frequency (50Hz) is not taken

straight from of your wall power, but cleanly generated by the motor control unit. You will not have any

fluctuations in speed caused by slight variances in the frequency from your mains power. The voltage

describes how silent your motor will run. Too much or too little voltage or fluctuations in voltage will cause

the motor to vibrate, which means that, basically, you are generating noise.

So that no motor vibrations reach the pickup, the Debut PRO has the new, proven motor suspension first

seen in our Debut Carbon EVO, which is responsible for the perfect decoupling of the motor.
