Unpacking and installation
Please also note if the turntable is part of a compact unit or a console
follow the instructions of the latter manufacturer.
Remove all transport protection information sheets and the
packing material from the turntable. Please read all notes before
removal
Remove the safety screw of the turntable (marked by a red
stripe) and loosen the transit safety screws (Fig. 1) by turning
them clockwise until they slide downward (above 15 mm)
releasing the chassis from the base
Then continue turning the safety screws clockwise to tighten
the screws. The turntable is now in the spring-supported posi-
tion required for play (Fig. B).

Next place the platter directly on the motor. Take the tonearm
counterbalance (1) from its styrofoam packing and screw it on
to the rear end of the tonearm (Fig. 2). Page 11 explains how to
balance the tonearm and adjust stylus pressure and anti-skating
The separate technical data sheet advises you on setting tracking
pressure for the cartridge included with the unit.
Later Transport
Important: the platter simply rests on the rotor of the electronic
direct drive and must be removed prior to any transport
Be sure the tonearm is locked and the stylus guard flipped
down. Also, release the transport safety screws counterclock-
wise, then pull them up and tighten again by continuing to turn
so as to secure the chassis against the base (Fig. C). The tonearm
counterweight should be removed
Should shipping of your Dual unit become necessary, make
sure that the packing is adequate. Use, if possible, the original
packing material in which you received your unit.
Attention: After each transport or installation, the unit must
be started once with the tonearm in locked position for auto-
matic adjustment of the shut-off mechanism. To initiate the
automatic "Start" or "Stop" function, press the start switch
all the way in each direction
Start and Operation
First select the correct platter speed, then unlock tonearm. If
the cartridge has a stylus tip protector, move it upward
1. Automatic start
Indexing is interlocked with the speed selector, so the tone-
arm will set down into the lead-in groove of 12" (30 cm) re-
cords when switched to 33 1/3 rpm, and into the lead-in groove
of a 7" (17 cm) record when set to 45 rpm. To initiate "aart"
function, press the switch (7) all the way. The switch returns
to its original position immediately after its release. The tone-
arm moves to the record, lowers slowly and sets the stylus gently
in the lead-in groove of the record
2. Manual start
a) Move cue control lever (6) to position Y.
b) Move tonearm by hand over the desired point on the record
c) Tap control lever to position Y
Attention!
With the cue control lever in position Y and automatic start,
the tonearm moves to the setdown position. By tapping the
control lever the tonearm will descend to the record
The height of the stylus tip over the record when the tonearm
is in the raised position by the cue-control can be varied about
approx. 6 mm by turning the adjustment screw (4)
3. If a record is to be played repetitively or played once more
from the start
Move switch to start"
4. Interrupting play (Pause)
Set the cueing lever to position X. When the cueing lever is re-
turned to position X , playing is continued. The last few notes
before the pause are repeated
5. Shut-off
Move switch to position ,,stop"
The tonearm will return to its rest position and the unit will
shut off automatically
Note: For records with other diameters, such as 25 cm records,
the unit is operated manually. See Section "2. Manual start"
After the record has been played, shut-off and tonearm return
is automatic irrespective of having started the unit manually or
automatically. The tonearm should then be locked and the
stylus tip protector moved down again.
Balancing the tonearm
Precise tonearm balance is most important for cartridges having
a low stylus pressure. Balancing need only be done once. We
recommend, however, that you occasionally check the tonearm
balance
The pick-up arm is correctly balanced if it remains in a horizon-
tal position when released, i.e. if it does not rest against the
lower or upper end stops and if it returns to a horizontal posi-
tion if deflected vertically by a small amount. The tonearm
is balanced exactly by turning the counterbalance weight (1)
1. With the pick-up arm still locked on the arm support, turn
the turntable a few revolutions in a clockwise direction by
hand.
2. Set the tracking force (2) and anti-skating (3) controls to
"zero" (with the pointer L/H), unlock the tonearm, and lift
it from the tonearm rest
3. Should the tonearm not come to rest horizontally, balance
the tonearm exactly by turning the counterweight (see
above.
4. Adjust tracking force and anti-skating
Setting the Stylus Pressure
Each cartridge has an optimum stylus pressure. See instructions
supplied with your cartridge
Once the tonearm is balanced exactly, the stylus pressure is set
to the recommended value for the cartridge by turning the stylus
force scale (2). The stylus pressure can be set to any value
from O — 30 mN (0 - 3 g) whereby the figures on the scale are
to be interpreted as follows.
1 = 10mN ^ 1g
2 = 20mN A 2g
3 = 30mN A 3g
The unit is designed to operate with stylus pressures from 5 mN
(0.5 g)
Antiskating
The skating force which acts upon any pick-up arm causes one-
sided wear on the needle and on the record and can cause
distortion in the reproduction.
To compensate for skating force, a counterforce, precisely de-
fined in weight and direction, must be applied to the tonearm
