Anti-skating force adjustment
The anti-skating force must be adjusted corresponding to the downforce as follows:
Downforce
Groove in the stub (15)
10 - 14mN 1 st from bearing rings
15 - 19mN 2 nd " " "
20mN and bigger 3 rd " " "
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 hang the thread in the groove of the wire support (17).
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, but in practice this is often not the case.
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.
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.
Connection to the amplifier
Connect the tonearm cables to 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 on your amplifier 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 which is then connected between the record player and a free line
level input of the amplifier.

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 (1) on the rear of the record player before
connecting the power supply to the mains.
Fitting the lid
Fit the lid (dust cover 24) carefully over the hinge prongs and adjust the screws (23) until the lid stays open
where you want it to without being too stiff to open or close.
