Dual 1215 Operating Instructions Manual page 8

Dear
record-lover: Please
read
these
instructions carefully before
you set
up
and operate
your new
automatic turntable.
By doing so, you will
avoid faulty operation
or
possible
damage
due
to
mistakes
in
installation.
Move
page 2
outward.
Unpacking
See
the
separate unpacking
instructions.
This
instruction applies
only
if you
have
bought
the Dual
1215
as a
separately
packed component.
lnstall
the platter
by
lowering
it
carefully and slowly onto
the
shaft.
An
oil-soaked
felt
washer
will
be
pushed
out as you
lower
the
turntable
platter,
thus oiling the
shaft.
lt
can
then
be
discarded.
lf
your
1215
does not
have
a
cartridge
installed, you will find
installation
instruc-
tions on page
10.
With the
tonearm locked
in
place,
install
the
counterbalance
at the rear of
the tone-
arm.
You will
find further
instructions for
balancing the
tonearm and setting
stylus
force on
pages
10
and
11
of
these
instruc-
tions. For the correct stylus force,
which
depends on the
make and model of
cart-
ridge,
follow the instructions provided
with
the
cartridge.
Note: After
initial
installation and
after
every
transport,
allow
the
automatic
me-
chanism
to
adjust itself by
operating
the
1215 through one
change
cycle
with
the
tonearm locked on its rest (move the opera-
ting
lever to
"start").
lnstallation
The installatjon instruction
is
only
important
if
the phonograph
is
bought without
bäse.
'
lf yoursystem
requires a preamplifier,
make
the necessary connections
to
the
Dual

The following instructions
are
exceedingly
simple:
Press the
chassis mounting screws
toward
the
edge
of
the chassis with your
thumbs
and set the
chassis down
on the
base cut-
out
so that the three spring cups
slip
into
their
holes
(A).
Then
turn the
mounting
screws cloctwise.
The
chassis
is
now
spring-mounted (B).
To secure the unit
for
transport, unscrew
the
mounting screws,
pull
them up,
then
turn
them
further until the chassis
is
se-
cured tightly to the
mounting board (C).
To
prepare the unit
for
use
again,
turn
the
two
screws clockwise
until they slide
down
about
3/4",
then continue
to
turn in
the
same direction until they are tight.
Power-line connections
For units
already
installed in
concole
or
com-
pact
systems, see
the
instructions
for
thq
system.
The unit can be
used
with
50
or
60
Hz
alternating current, at
1 1
0 or
220
volts.
lt
is
normally pre-set for
220 volts,
50
Hz.
The voltage
for
which
the unit
has
been
pre-set
can be read on the voltage selector.
The frequency
will
be found on the
name-
plate. Both can be found on the
underside
of
the
chassis.
ln
units
without
a
voltage selector,
the
correct
operating voltage must be set
by
inserting the motor power cable into
the
appropriate terminals according to
the
drawing in
the power switch
cover.
The power switch
is
designed
so that
pre-
amplifiers
or
poweramplifiers can be swit-
ched
on
or
off
automatically
as the unit
is
turned on
or
off.
The load
on the
power switch must
not
exceed
400
VA (Volt-amperes). It is gener-
ally used
only with all-transistor
amplifiers,
which have no warm-up
delay.
The connection
is
made
to
contacts pro-
vided on
the plug
portion
of
the
power
switch.
ln
this
case,
the line cord
is to
be
fitted
wjth AMP plugs as
follows:

Connection to amplifier
For units
already
installed in
systems,
consult
the
instructions for the
system.
The unit can be
fitted
with
DIN
41
524
miniature connectors (Fig.
4)
or with
phono
(RCA) plugs
(Fig. s).

lf
your
amplifier
is
fitted
with
a
different
type
of
connector, use
sultable
adapters,
available from audio
dealers.
lf
the unjt is to
be connected
to
a power-
transformerless
("ac-dc")
radio,
amplifier
or other
equipment,
a
suitable
ground
connection
must
be
made
to
prevent
a
possible shock
hazard.
A
contact
is
avail-
able for this purpose
on the power
con-
nector (Figs.
2 and
3).
