Remove the safety
screw which, in
some
cases,
is additionally
mounted on the
left
rear side.
To
release
the transport
locking
screws
(Fig.
1)
turn
these
in
clockwise direction
until
they slide down approximately
1b
mm
and
then tighten
these
by turning
them
further in
clockwise
direction. ln
this
way,
the record player
is spring mounted
in
playing
position
(B)
Remove
the tonearm counterbalance from the polystyrene
in-
sert and place the stem
of
the counterbalance, after
releasing
the
locking screw
(3),
into
the opening intended for
this
at the
back end of
thetonearm Atthesametime,the
triangular
recess
on the
stem
should
point
downwards
(Fig.
2).
Balancing
as
well
as
setting of
stylus pressure
and anti-skating
which
ls
now
necessary are described
in
more detail on pages 12
and
13.
Please
refer
to
the separate data sheet for the stylus pressure
of
the cartridge already
inserted
in the unit.
Now connect to
the
reproducing
amplifier
and
place the
mains
lead
into
the socket.
Please
pay attention to
the separate infor-
mation
in these instructions.
Subsequent
transport
Make sure
that the
tonearm is locked
and
that
the stylus pro-
tection is
swivelled downwards.
ln
addition,
the
transport
locking
screws
must be loosened
in
anti-clockwise direction,
pulled
upwards and secured
by further turning
(A).
The tone-
arm counterbalance
should
be removed.
lf you
intend to dispatch
your unit,
make
sure
that
the
packaging
is
impeccable and,
if
possible,
use
the original packaging.
Dust cover
For
placing the dust cover turn the unit
in such
a
manner
that
the special hinges are readily
accessible. Make sure that the in-
serting
joints (Fig.8/A)
of the
hlnges
into
which the
covershall
be pushed in
are well
placed before
the dust
cover
is
paralleled
to the position of the
inserting
jolnts
and
depressed
(Fig.9).
ln this position
(tilted
at approx. 600) the
dust cover may
be
removed completely
(Fiq.
10).
For
adjustment
of
spring relief
(the cover
is
kept by
spring
force
in
its position)
turn
both
screws marked
"R"
accordingly
(Fis.
1

).
For
consoles
with
relief
screws
"R"
arranged
as
shown
in Fig.8
remove
the
dust cover and adjust spring tension
screws
in
the
same
manner. ln most
cases
half
a
turn
will.be
suff icient.
Connection
to
the
ac mains
The
unit
can
be
operated on
alternating current,
50
or 60
Hz,
1101125
or
22O1240
V
At
the factory,
50 Hz
units
are set
for
23O
Y; 60
Hz
un
its for
1

5 V.
Conversion
of
the
mains voltage should
only
be
carried
out
by
your
specialist dealer
or
by
an
authorized Dual
service
station.
Connection to the amplif
ier
Connect
the
cartridge lead equipped
with
RCA
(cynch)
plugs
to
the
phono-magnet input of
the amplif ier
(black
=
right
chan'
nel, white = left channel).
Connect the one wire equipped
with
the cable bracket or
screw
it
under
the clamp mar(ed
"GND"
on the rear of 'the amplif
ier.
So
that
your
receiver
or
reproducing amplif ier
be designed
for
DIN
jacks,
have
your
specialist
dealer adapt
this by
replacing
the complete cartridge
lead.

Dual cartridge
leads
can also be equipped
for plug-in into
the
tu
rntable.
Please
do not
forget
to
connect
the
chassis
lines
of
the right-
hand
(green)
and left-hand (blue) tonearm
lines
to the
chassis
of
the unit
when converting
this from

DIN
jac
ks.
An
equalized-amplif
ier
is
necessary
if
your
stereo
amplifier or
receiver has
no direct input
for
magnetic cartridge systems. ln
12
thrs case,
we
recommend
the
Dual
M
47
which
is
equipped
with plug-in
connections.
Setting up and operation
Select
platter
speed,
33
113
or 45
rpm, then unlock
tonearm,
move
stylus
tip protector
upwards.
Now
remove tonearm
f
rom post and swing
it
over
the
record.
After
the tonearm
has
been swung over the
record the
turntable
platter automaticallystartsto
rotate.When the tonearm
is
lifted
from its
post and
placed
beside the tonearm rest, the
platter
will
rotate. The record on
the platter
can
be cleaned
(with
an
antistatic cloth
etc.)
when the tonearm
ls
in this position.
ln
order
to
lower the
tonearm
to
a
specific position
of
the
record only
a
light touch of
the
guide lever
(6)
will
do.
The
cueing
Iift
now
operates and the stylus is
placed
care-
fully
on
the
record.
At
the end
of
the
record, the tonearm lifts
off
the
record and
the cue-control
lever returns
to
the
v
position.
The motor
then
switches
off
automatically.
lt
is
recommended
to
lock
the
tonearm
and
to
f
lip down the stylus protection after
play.
lnterrupting play
(Pause)
Set
the
cueing lever
(6)
to position
I
When the cueing lever
is
returned
to
position
I
,
playing is
continued. The last
few
notes before
the
pause are repeated.
Balancing the
tonearm
Precise
tonearm
balancing
is
important,
above all
for
cartridges
with
a
low stylus
pressure. The tonearm
need
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 and
if
it
returns
to this horizontal
posi-
tion
if
pushed upwards or
downwards.
Shiftinq the
counterbalance
(2) on
its shaft
balances the tone-
arm
coarsely;
turning the
knurled
ring
of the
counterbalance
weight
balances the
tonearm exactly.
1. Set
the
tracking force
(4)
and anti-skating
(5)
controls to
"zero"
(with
the
pointer L/H).
2
Unlock
the
tonearm and
move
it
over
the
tonearm
rest.
Place the cue-control
lever
(6)
in
t'
position.
3. lf
the
tonearm
does
not return to
a
horizontal position
on
its own,
release
the
locking screw
(3)
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
knurled
ring
of
the counterweight.
5.
Set the stylus pressure
and anti-skating.
Setting stylus pressure
Each
cartridge requires
a
certain stylus pressure with which
op-
timum
reproduction
is
obtained.
You
will find
this specification
for the fitted
cartridge on the enclosed data
sheet.
lf
the tonearm
has
been
exactly
balanced, the
stylus
pressure
necessary
for the carlridge
is
set by turning the stylus pressure
scale
(4).
The stylus pressure
can be continuously set
within
the
range
from
0 to 30 mN
(0
-:
p1
,whereby the
digits
on
the scale represent
the following.

Anti-skating
The skating force
acting upon each
tonearm
leads
to
one-sided
wear and tear
of
the stylus and
record and can cause distorted
reproduction.
In order
to
balance
out the
skating force,
a
counterforce
exactly
def
ined
with
regards
to
size
and
direction
must
be applied. The
anti-skating device
(5)
of your HiFi
record player
fulfills
this
requirement.
