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

from bearing rings
15 - 19mN

20mN and bigger

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 3
rd
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
