Dual CS 607 - Cartridge and Stylus

To
eliminate
these
problems,
Dual’s
new
generation
of
turn-
tables
is
equipped
with
tunable
acoustic
isolators.
(Fig.
6).
Interference may be caused by:
1. External vibrations. They occur when the turntable is placed
on a table or shelf in a room with wooden floor. External
vibrations, such as footsteps are transferred from the floor
to the furniture and from there to the turntable. Solution:
rotate the dial rings of the acoustic isolators clockwise (+).
2.
Acoustic
Feedback.
A
loud,
howling
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
shelf.
Solution:
rotate
the
dial
rings
of
the
acoustic
isolators
counterclockwise
(—).
All
four
acoustic
isolators
should
be
adjusted
by
the
same
amount.
This will provide optimum acoustic isolation.
Cartridge and stylus
Please refer to the enclosed data sheet supplied separately with
your unit.
Replacing the cartridge (Dual TKS .. . )
You may release the complete cartridge from the tonearm by
pressing the tonearm lift 10 to the rear. When doing this, firmly
grip the cartridge as it will fall off once the locking device has
been released (Fig. 7).
The
tonearm
lift
may,
however,
only
be
moved
to
the
rear
if
you
have
previously
removed
the
safety
screw
11
(Fig.
8).
In order to replace the cartridge (Dual TKS .. . ) you must
place
it
from
below
against
the
headshell
so
that
the
front
edges
are flush. Please ensure that the cartridge lies absolutely flat on
the headshell before pulling the tonearm lift to the front in order
to
lock
it
in
position
(Fig.
8).
You
may
then,
if
desired,
reinsert
the safety screw 11
Stylus
The stylus is subject to natural wear and tear during normal
playing.
Therefore,
we
recommend
you
occasionally
check
the
stylus
and,
in
the
case
of
diamond
styli,
this
should
be
carried
out
after
approximately
300
playing
hours.
Your
specialist
dealer will be pleased to do this for you free of charge. Worn
or damaged (splintered) styli chisel the modulation from the
grooves and destroy records. Therefore, only use as replacements
the
stylus
types
recornmended
in
the
technical
data
of
the
cartridge.
Imitated
styli
result
in
audible
quality
losses
and
in-
creased
wear
and
tear
of
records.
Please
remember
that,
for
physical reasons, the stylus holder with the diamond stylus is
extremely fine and must therefore be necessarily sensitive to
impacts, shocks or uncontrolled movement.
When
removing
the
stylus please
note
the
information
contained
on
the
separately
enclosed
data
sheet
referring
to
the
cartridge
on
your
unit.
Fitting a cartridge
In the case of units delivered without a cartridge, or if you wish
to fit a cartridge of your own choice.
All cartridges having a total weight of 4.5 — 10 g (including the
attachment fittings) may be fitted. Units without a cartridge
are supplied with the necessary fitting accessories (also available
as special accessories under the Dual part No. 269 611 — in the
case
of
turntables
with
tuning
anti-resonator
—
Dual
part
No.
266 048)
We
recommend
that
you
fit
an
original
Dual
cartridge
(Dual
TKS...),
characterised
by
its
low
mass
and
problem-free
in-
stallation.
(Refer
to
the
section
“Replacing
the
cartridge
ITKS...)".)
The 1/2" cartridge is fitted as follows
1) If necessary, remove the safety screw (Fig. 8/11)
2) Remove the cartridge from the headshell as described in
the section "Replacing the cartridge”
3)
Attach
the
1/2”
cartridge
to
the
mounting
plate
with
the
aid
of
the
system
installation
gauge
and
using
the
acces-
sories
enclosed
with
the
cartridge.
This
has
been
correctly
installed
if
the
tip
of the
stylus
—
viewed
from
above
—
is
in the
V-shaped
recess
of
the
system
installation
gauge.
Viewed
from
the
side,
the
stylus
must
be in
the
area
of
the
rectangular
recess
(Fig.
9).
4)
Connect
the
connections
of
the
headshell
to
the
connecting
pins
on
the
cartridge.
The
connections
are
color-coded:
Red R right channel
Green RG right channel ground
Blue GL left channel ground
White L left channel
When fitting the retaining plate with the cartridge fitted,
ensure that the front edge of the black plastic section is
flush with the headshell. The metallic-coloured mounting
plate projects approx. 5 mm.
6)
If
the
cartridge
has
a
total
weight
of
more
than
6
g,
you
must fit the additional weight included as an accessory. For
this purpose, screw the countersunk screw completely into
the additional weight and then screw this into the rear of the
tonearm counterweight.
In the case of turntables fitted with a tuning antiresonator,
screw 1 or 2—dependingon the total weight of the cartridge —
of the disc-shaped additional weights included as accesories
onto the rear of the tonearm counterweight 1 .
5;
Cartridge - Total weight - Including hardware
upto 6g 1 thin disc
upto 7g 1 thick disc
upto 9g 1 thick disc and 1 thin disc
up to 10g 2 thick discs
Screw the smaller thread of the special screw into the coun-
terweight 1. With the bevelled side to the outside, screw
the corresponding additional weights onto the thicker part
of the screw.

Now
once
again
carefully
balance
the
tonearm
as
described
in
the
section
“Balancing
the
tonearm”
and
set
the
stylus
pressure
and
anti-skating
force
required
for
your
cartridge.
After
having
mounted
a
cartridge
check
the
height
of
the
playing
needle
above
the
record
with
the
cue
control
in
position
a

See
section
“Cue
control”

Servicing
All
the
lubrication
points
have
sufficient
oil.
Thus,
your
unit
will
operate
impeccably
for
many
years
under
normal
condi-
tions.
Never
try
to
lubricate
any
of
the
lubrication
points
your-
self.
If
your
record
player
should
ever
need
servicing,
either
take
it
to
your
specialist
dealer
or
ask
him
for
the
address
of
the
nearest
authorized
Dual
Servicing
Workshop.
Please
make
sure
that
only
original
Dual
replacement
parts
are
used.
Should
the
unit
ever
be
dispatched,
make
sure
that
this
is
packed
perfectly,
if
possible,
by
using
the
original
packaging
The platter
The platter lies directly on the motor spindle and, when placed
in position, is automatically fixed through its own weight. Aa
ditional locking is not necessary and is also not provided for.
Important! Remove the platter before transporting the unit!
Subsequent transport
If
you
wish
to
transport
the
unit
over
long
distances,
we
re-
commend
that
the
cover
and
the
platter
is
removed.
The
coun-
terweight
should
also
be
removed.
Ensure that the tonearm is locked and the stylus cover is in position.
Electrical safety
The
unit
complies
with
the
International
Safety
Regulations
for
radio
and
related
devices
(IEC
65)
and
the
EEC
guidelines
76/889/EWG.
