Set-up
The deck is supplied partially disassembled and carefully packaged for safe transport. Carefully remove
all parts from the transport packaging.
Make sure the surface you wish to use the turntable on is level (use a spirit level) before placing the
turntable on it.
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 over the spindle of the hub. Level the plinth using a spirit level and the adjustable feet
(23).
Remove the transport lock (18) from the tonearm. Store it in the original packaging so it is available for
any future transportation.
We recommend to use the record player without a mat on the platter.
Cartridge downforce adjustment
The counterweight (6) supplied is suitable for cartridges weighing between 6 - 8g (counterweight
no.48). Alternative counter-weights for cartridges weighing between 4 – 6g (counterweight no.49),
8 – 10g (counterweight no.28), 9-12g (counterweight no.30) are available as accessory part.
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), 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 18mN.
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 hexagon screw 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 hexagon screw without applying excessive force (which would deform the arm
pillar) – finger tight is quite sufficient.
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.
Please note: do not remove the screw completely!
