Dear music lover
Please
read these
instructions carefully
before
you
start
using
your
Dual
so
that you
will
not
encounter
any problems resulting
from faulty
connections
or
handling.
Move page

outward.
Unpack
Remove
all
parts
used
for
packing,
including
the
wedges
between
the
chassis
and the
plat-
ter.
Notice whether
a cartridge
is
mounted
in
the
tonearm
head
and
remove
the
protective
cap
that
may
be
over
the
stylus.
Remove
the
needle
protector.
Please
follow
the instructions
on
the
special
cartridge
leaflet,
lnstructions
for
setting the stylus force
are
found
on
page
7.
The
technical
data
of
the pick-up
cartridge
are
to
be
found
on
a
separate
information
sheet
enclosed
to
this
instruction. Turn
the
two
securing
screws
clockwise
until
they
slide
about
'1
.5 cm down,
and
tighten
them
with
further
clockwis€
turns.
This
secures
the
chas-
sis
in
springmounted
play
ing
position
( F

Setting up the loudspeakers
Fig.2
For optimum
stereo
reproduction,
the
pair of
speaker systems
should
be
positioned
so
that
the
space
between
them
is
approximately 2/3
of
the
distance
from their
midpoint
to
the
listener.
Their height should
also be
approxi-
mately
that of
the
listener's
head.
The
enclosures
are
finished
on all
four
sides,
allowing them
to be
placed
either
vertically
or
horizontally.
The
cable
con-
nections
are
recessed,
allowing
the
enclosu-
res
to
be
hung
f
lush
to
the wall.
Dual
em-
blem
can be
turned
around. Felt
tips
are
en-
closed
for
placement
on
f
urniture.
When
room
configurations
do not
permit
conventional speaker placement
for
stereo,
they
can
either
be
tilted
down
or
toward
the
center
so
that the
stereo
effectiveness
is
kept
sufficiently broad
in the
general
listening area,
The
balance
control
can
also
be adjusted when compensation is
required,
Connection
to
power supply
The
Dual
operates
on
110/150
or
22OYAC,
50
or 60
Hz,
and
is
usually set
for
22O
volts
50
Hz.
It
requires readjustment
for
operation
on
a
different
voltage
or
frequency.
The
voltage
adjustment
(c)
is
located
on
the
connection
panel
on the
back
of
the
case,
and
requires
only
a screw-driver.
ln
regard
to
voltages
of
130
and
24O V,
this
should be done
only by a
competent
serviceman.
ln
addition
to
this,
the
jum-
pers should
be
resoldered
at the
power
transformer as described
on the wiring
dia-
gram.
The
voltage selector can be set
at
130,
1
50
or
240 volts.
The adjustment
is
simultaneous
for
amplif
ier
and
record
player.
lt
does
not
necessitate
changing
the
fuse.
Defective fuses
can
be
changed
after
loosening
the
screw
and
remo-
ving
the sliding
cover.
b
=
line fuse
for
110, 130, 150 V
d
=
line
fuse
for
22O,24OV
Caution!
Be
sure
to
disconnect
the
line
plug
before touching the
voltage adjustment
or
removing
the sliding
cover!
Connection
to
tape recorder
or
separate
amplifier
The
output
receptacle
"Q",
mounted on
the
connecting
plate,
gives
the possibility
using
the
turntable
without
the
built-in
amplifier
of
the
unit.

Before transporting
the unit,
simply
loosen
the
screws
with
counter-clockwise turns,
lift
them up and continue tightening
them coun-
ter-clockwise
Loudspeaker connections
The
speakers are
connected
with
the
enclosed
cables
CA
3
to
the
sockets
marked
4
(stan-
dard
receptacles
DIN
41
529)
on the
rear
of
the
unit.
Sneqfer connections
left
and right
are
with
reference
to the
I
istener.
These cables
come12 feet
long and
can readily
be
shortened.
ln
special
cases
where
the
stan-
dard
length
will
not
reach',
the
loudspeaker
extersion
cable
(approx.
39
feet
long),
article
no. 223139,
is gecommended
and available at
your
dealer
lmportant!
Make certain
that the
loudspea.
kers connected
to
each
channel
have
a
combi-
ned
impedance
of
at
least
4
ohms. Failure
to
observe
this
precaution
may
cause a
short cir-
cuit!
Do not attempt to
connect
several
loud-
speakers
in parallel
to
the
Dual.

ln
this
case
the
output
receptacle
"Q"
must
be
connected
with
the
phono-input
of
the
separate amplif
ier (phono-input approx.
200
mV
at
47O
kOhm).
For the
recording
of
records
on
tape
there
must be
a
connection between
output
re-
ceptacle
of
the
phonograph
and
the
input
receptacle
"Phono"
of
the tape recorder. ln
both
cases
the audio
cable,
part
no.
203
634
may
be used.
The
output
receptacle
can also
be
used
as
an input
for
usual program sources (tape
re-
recording
or
connection
of
a
tuner). For
the
full
modulation
of
the
built-in
stereo ampli-
fier
an input
voltage
of
approx.
400 mV
at
470
kOhm
is
necessary. Remove
the
con.
nection
for
the
recording
of
records.
