Balancing the tonearm (with cartridge installed)
Preparation
1. Connect turntable to AC outlet, or to jack (unswitched) on
rear of your amplifier or receiver.
2. Press POWER switch (22) to turn turntable on.
3.
The
|
¥
)
arrow
above
the
lift
switch
(13)
should
be
illu-
minated.
If
not,
press
the
switch.
4.
With
the
tonearm
locked
on
its
rest
post,
press
the
START
switch
(15)
once.
5. Switch the turntable off by pressing the POWER switch (22)
again.
Balancing procedures
1. Set tracking force dial (4) to 0 and pointer of anti-skating
dial (7) to left (off position).
2.
Unlock
the
tonearm
and
pivot
it
toward
platter
over
the
tonearm
rest
bar.
3.
For
coarse
balance,
loosen
locking
screw
(2)
and
shift
the
counterbalance
with
the
shaft.
Then
tighten
the
locking
screw.
4.
For
fine
balance,
turn
the
front
knurled
ring
of
the
counter-
balance.
The tonearm is correctly balanced when it floats horizontally
over
the
rest
bar
and
when
it
returns
to
this
horizontal
position
after being gently pushed up or down.
Tracking Force Adjustment
In
order
to
provide
optimum
reproduction
of
the
sound
signals
cut
into
the
record
groove,
a
certain
pressure
—
called
“tracking
10
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 0 to 20 mN (0 - 2 g), whereby the digits on the scale
represent the following.
1 = 10mN 4 1g
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 g).
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:
Mon
Tracking force setting Antiskating
”Dry'-playing “Wet” playing

12.5 mN A 1.25p 1.25 08
15 mN415 p 1.5 1.0
20 mN420 p 20 13
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
auxiliary
power
outlets
of
certain
amplifiers.
Connection to amplifier or receiver
Connect
the
audio
cables
to
the
phono-magnetic
inputs
of
the
amplifier
or
receiver.
(Black
RCA-type
plug
=
right
channel,
white
RCA-type
plug
=
left
channel.)
Connect
the
ground
wire
to
the
ground
connection
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.
207
303)
as
required.
