Balancing
the tonearm
Precise
tonearm balancing
is
important,
above
all
for
cartridges
with
a
low stylus pressure. The tonearm
needs
only
be balanced
once. However,
it
is
recommended
to
check
the tonearm balance
from
time
to
time.
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.

lf
the tonearm does
not return
to
a
horizontal position
on
its own,
release
the lockinq
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
4.
Now find the
exact balance
by turning the
f
ront knurled ring
of the counterweight.
Setting
tracking force
Each
cartridge
requires a
certain tracking force with which
op
timum
reproduction is
obtained.
lf
you
purchased
your
Dual
with
a
factory-mounted cartridge,
you
will
f
ind this
specifica-
tlon for
the
fitted
cartridge on
the enclosed data
sheet.
When
the tonearm
has
been
exactly
balanced, the
tracking force
necessary
for
the cartridge
is set
by
turning the tracking force
scaie (41. The{racking 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=

2=2OmN4

A
graduation
mark in the
range
from2-
15
mN
(O.2

is
equivalent
to this

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.
o
Setting
for
biradial (elliptical) styli
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
Fitting the
cover
lnsert the
cover
into
the slots on the
two
hinges
(3)
located
on
the
chassis.
lt 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.
lf
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.4):
Fotating 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 22O-24OVl5O or60
Hz or
to
1
10
-
125
V
l5A or 60
Hz.
Resetting
the
mains
voltage must
only
be carried
out
by
your
dealer
or by
an
authorized Dual
seruicing agent.
The
unit
may
also
be
connected
to
the
jacks
provided
on
suitably equipped
ampl
ifiers.
Connection to the amplifier
Connect
the
cartridge
lead equipped
with
RCA
(cynch)
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 amplif ier.
lf
your
receiver
or
anrplifier is designed
for
DIN
jacks,
your
dealer may convert
your unit with the
cartridge lead pro-
vided
with
a
DIN
plug,
1 10
m long, available
as
a special acces-
sory, itern no.

Setting up and
operation
Before playing the first
record
or
if you
have
transported the
turntable, please adjust
the pickup
arm
return
mechanism
as
f
ollows:
1.
Release
the pickuparm
and
raise
it
by pressing
button
A(10).
2.
Swing
the arm
to
the
center
of
the
turntable.
(The arm will
return automatical
ly).
Select
platter speed,33
1/3 (15)
or45 rpm
(16),by
pressing the
relevant
button then unlocktonearm, move stylus
tip protector
upwards.
Now
remove tonearm
from post and swing
it
over
the
record.
After the
tonearm has been swung over
the
record
or
placed
on the
tonearm rest
the turntable platter
automatically
starts
to
rotate. The
recorä
on the platter can
be cleaned
(with
an
antistatic
cloth etc.) when the tonearm is in
the
rest position.
When
the
tonearm reaches
the record diameter
of
30
cm
or
1J cm
a
detent
is perceptible. This
indicates
the correct
set-
down
point for
the
diamond to the lead'in groove of the record.
This aid
for
the correct setting
of the tonearm
may beswitched
off.
ln
order
to
lower the tonearm
to a specific position
of
the
record press
button
v
(11).
After
playing
the
record
the tonearm
will
automatical
ly lift,
be returned
to the
tonearm post and
the
unit
will
switch off.
We suggest
you flap down the stylrrs guard after
play.
