Tracking Force Adjustment
In order to provide optimum reproduction of the sound signals
cut into the record groove, a certain pressure — called "tracking
force" — must be applied on the stylus. If you purchased your
turntable with a factory-mounted Dual cartridge, you'll find
the correct tracking force in the spec sheet supplied with the
unit.
After adjusting the tonearm balance as described above, set the
tracking force by adjusting the dial ring of the counterweight (4),
The tracking force can be continuously set within the range
from O to 20 mN (0 - 2 g), whereby the digits on the scale
represent the following.
1 = 10mN A 19
2 = 20mN A 2g
A graduation mark in the range from 2 - 15 mN (0.2 - 1.5 g) is
equivalent to this 1 mN (0.1 a)
The unit works reliably from a tracking force of 2.5 mN
(0.25 g) onwards.
Anti-skating
The skating force acting upon any tonearm leads to one-sided
wear
of
the
stylus
and
record
and
can
cause
distorted
repro-
duction
For
stylus
types
generally
available
nowadays,
separate
setting
scales are available in accordance with the printed symbols
O Setting for spherical styli
© Setting for biradial (elliptical) styli.
Adjustment of the anti-skating device should be carried out
to match the setting of the stylus pressure

Adjustment of Tonearm Balance
Before
adjustment
of
the
tonearm
balance,
connect
your
turn
table
to
an
AC
wall
outlet
and
depress
the
POWER
switch
(21)
For
further
details,
please
refer

Check
which
of
the
two
arrow
marks
above
the
LIFT
pushbutton
(13)
is
illuminated.
If
the
w
arrowmark
lights up, release the tonearm lift by depressing the LIFT push-
button.
To
disengage
the
automatic
tonearm
system
when
the
tonearm
is
locked
on
the
arm
rest,
depress
the
START
push-
button (15) once
Now switch the unit off by depressing the POWER switch (21)
again
Adjust tonearm balance as described below.
The
tonearm
is
balanced
if
it
remains
in
a
horizontal
position
when suspended freely (moved inward from its resting post)
and if it returns to this horizontal position if pushed upwards
or downwards.
Shifting
the
counterbalance
(1)
on
its
shaft
balances
the
tone-
arm
coarsely;
turning
the
front
knurled
ring
of
the
counter
balance weight (1) balances the tonearm exactly.
1.
Set
the
tracking
force
(4)
to
O
and
the
anti-skating
device
(7) to “off” (pointer to left).
Unlock
the
tonearm
and
pivot
it
towards
the
centre
of
the
platter over the tonearm rest
2,
If
the
tonearm
does
not
return
to
a
horizontal
position
on
its
own,
release
the
locking
screw
(2)
and
shift
the
counter-
balance
with
the
stem
until
you
have
an
approximate
balan-
ce.
The
stem
of
the
counterbalance
should
then
be
locked
by tightening the locking screw,

Now
find
the
exact
balance
by
turning
the
front
knurled
ring of the counterweight
Tracking force setting Antiskating

The skating force is reduced by approximately 1/3 in the case
of
“wet”
playing
(playing
records
moistened
with
liquid).
The antiskating device is switched off when the pointer is set
to the left.
Dust cover Installation
Insert
the
cover
into
the
slots
on
the
two
hinges
(3)
located
on
the
chassis.
It
will
be
easier
to
insert
or
remove
the
cover
if
the
slots
on
the
cover
hinges
are
in a vertical
position.
The
cover
will
remain
in
any
desired
position
when
opened
a
few
centimeters.
If
it
should
become
necessary
to
reset
the
spring
pressure
that
maintains
the
cover
in
position,
this
may
be
done
by
rotating
the
screws
accessible
at
the
rear
of
the
unit
(Fig.
6)
Rotating the screws clockwise —
increases the spring pressure
Rotating the screws counterclockwise —
decreases the spring pressure
Connection to the AC supply
Depending
upon
the
voltage
rating
on
the
nameplate,
the
turn-
table
is
set
either
to
a
voltage
of
220
—
240
V/50
or
60
Hz
or
to 110
—
125
V/50
or
60
Hz
Resetting
the
line
voltage
must
only
be
carried
out
by
your
dealer
or
by
an
authorized
Dual
servicing
agent.
The
unit
may
also
be
connected
to
the
auxiliay
power
outlets
of
certain
amplifiers
Connection to the amplifier
Connect
the
cartridge
lead
equipped
with
RCA
(cinch)
plugs
to
the
phono-magnet
input
of
the
amplifier
(black
=
right
channel,
white
=
left
channel).
Connect
the
one
wire
equipped
with
the
cable
bracket
or
screw
it
under
the
clamp
marked
"GND"
on
the
rear
of
the
amplifier
If your stereo amplifier or receiver is equipped with 5-pole
DIN phono sockets, a special phono adapter (Dual Part Nr.
262
483)
is
required
for
connection
of
your
turntable.
This
adapter
cable
can
be
obtained
as
optional
accessory
from
authorized Dual dealers. You may also have your turntable
modified at any Dual service center by installing the optional
phono cable with DIN-plug (Dual part Nr. 207303) as required.
