Regardless
of
operating mode (automatic or
manual
), the tone-
arm
will
return
to
the arm
rest
automatically at
the end
of
the
record.
Sir,nultaneously
the
power
will
be
cut off

the
platter stops rotating. We
recommend
to
always
lock
the
tonearm
to
the
arm
rest and
to
swing
down
the stylus
guard
when
the turntable
is
not
in
use.
Tonearm

This
function
overrides
the automatic operation.
For example,
if
the

After
depressing

goes
off
and
the

with

it

After
releasing
the PITCH pushbutton (18) tne OUARTZ
indi
cator
lights up again. Rotational
speed
of
the turntable platter
will
be
quartz controlled
and
corresponds exactly
to
the
selected
nominal
speed
without

to
the adjustment
of
the
PITCH
conrrol

Precise
stroboscope patterns etched
into
the
turntable
platter
rim are
illuminated
by a
special
LED
strobelight
(20).
See
Fig.
4.
The sequence
of
light
pulses
corresponds
to
the
quartz-
stabilized frequency which controls the motor
speed.
This indi
cator
functions
independently
of
line
frequency and
does
not
require
several
stroboscope patterns
for
different
speeds and
line frequencies.
Tunable
acoustic insulators
One
of
the
most frequent problems in turntable operation
are
vi
brations
of
various
origins,
being
picked up
by
the turntable
chassis
and
transferred
to
the cartridge, which converts
these
vi
brations
into
inter{erence
si
gnals.
To
el
iminate
these problems,
Dual's new
generation
of
turn-
tables
is
equipped
with
tunable
acoustic
insulators. (Fig.
10)
Interference
may
be
caused
bv:
l.
External
vibrations. They occur
when the
turntable
is
placed
on
a table
or
shelf
in
a room
with
wooden
floor.
External
vibrations,
such
as
foctsteps
are
transferred
from the floor
to
the furniture
and
from
there
to
the
turntabie. Solution:
rotate the dial
rings
of
the
acoustic insulators
clockwise
(+).
2.
Acoustic
Feedback.
A
loud, howllng
noise
will
be
encoun-
tered
when sound
waves
radiated
by the
loudspeakers
are
being
picked up by the
cartridge.
Acoustic
feedback
is
most
likely
to
occur when
speakers
and
turntable
are
installed
in
the
same
shel
f
.
Solutioni
rotate the
dial
rings
of
the acoustic
insulators countercl
ockwise
(
-)
All
four
acoustic insulators
should
be adjusted
by
the
same
amou
nt
This
will
provide
optimum
acoustic
insulation.
Alignment of the tonearm landing point
When
the START
button
(15)
is
operated, the
stylus automati
cally
lowers
itself
into
the
lead-in
groove
of
the
record.
lf,
in
the
case
of
a
subsequently
fitted
cartridge
for
example,
the
stylus sets
down
too
far
from
the
lead-in groove,
the
landing
point
of
the
diamond stylus can
be
corrected
with
the
align
ment screw (8).
lf
the
stylus sets
down
too far
inside
or
outside
the
record,
turn
the
alignment screw
to
the
left
or the right
accordingly.
The setting
is
effective
not
only
for
17
cm but
also
for
30
cm
records.
Cartridge and stylus
Please
refer
to
the
enclosed data
sheet
supplied separately
with
your
unit.
lnstalling cartridges
Note:
lf
you
purchased
your
Dual turntable
with a
ULM
cartridge,
it
has
already
been installed
and mounted
in
the
tonearm.
lf
you
wish
to
use
an
additional
cartridge
with
11Z-inch
mounting center,
an
optional mounting
kit
is
included
or
available
from your
Dual
dealer.
Replacing
the cartridge
You
may
release
the
complete cartridge
from the
tonearm
by
pressing
the
tonearm
lift
(
12)
to
the
rear.
When doin
g
this,
f
irmly
grip
the
cartridge
as
it will
fall off
once
the locking
device
has
been released
(Fig.
B)
The tonearm
lift
may,
however,
only
be moved
to the
rear
if
you
have
previously
removed the safety screw
(11)
(Fig.
11).
