Dual CS 506 Instrucciones De Manejo página 14

So that your receiver or reproducing amplifier be designed for
DIN jacks, have your specialist dealer adapt this by replacing
the complete cartridge lead
Cartrige lead with DIN jack 1.10 m long
Order number 207 303
Dual cartridge leads can also be equipped for plug-in into the
turntable
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 cynch (RCA) to DIN
jacks
An equalized-amplifier is necessary if your stereo amplifier or
receiver has no direct input for magnetic cartridge systems. In
this case, we recommend the Dual TVV 47 which is equipped
with plug-in connections.
Dust cover
In order to place the dust cover in position, turn the unit round
so that the special hinges are in front of you and are easily ac-
cessible. First of all make sure that the insert brackets on the
hinges, into which the cover will be placed, are in correct posi-
tion before you place the dust cover in position parallel to the
brackets and push this in fully
In this position (opening angle approx. 600) the cover can also
be removed at all times.
Should it be necessary to correct the balancing moment (elastic
force which keeps the cover above the console), this can be
carried out by turning both knurled screws. Please adjust both
screws equally. In most cases, correction by half a screw turn
each will be sufficient
Setting up and operation
Select platter speed, 33 1/3 or 45 rpm, then unlock tonearm,
move stylus tip protector upwards.
Now remove tonearm from post and swing it over the record
After the tonearm has been swung over the record the turntable
platter automatically starts to 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 is in this position.
In 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 lift now operates and the diamond 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 Y position. The motor then
switches off automatically, It is recommended to lock the
tonearm and to flap down the stylus protection after play.
Interrupting play (Pause)
Set the cueing lever to position Y . When the cueing lever is
returned to position Y. , playing is continued. The last few
notes before the pause are repeated.
Technical information
Cartridge and stylus
Please refer to the "Information on your unit's cartridge'', en-
closed with these instructions for use.
Installation of a cartridge with 1/2"
standard attachment (see page 27)
Depending on the unit type purchased, the assembly acces-
sories for 1/2" cartridges can consist of special accessories
which do not form part of the unit's standard equipment
The tonearm of your Dual HiFi turntable is designed for HiFi
magnetic cartridges with a 1/2 inch standard attachment and a
total weight of 4.5 to 10 g including attachment material.
Should you wish to install a different cartridge, proceed as
follows:
1. If necessary, remove the locking screw (Fig. 4/s).
2. Remove the cartridge by turning the attachment screw (10)
in anticlockwise direction At the same time, hold the cartrid
ge as otherwise it will drop from the mount (Fig. 5). Remove
the tonearm lines from the contact pins of the cartridge.

3. Attach the 1/2" cartridge to the mounting plate with the
aid of the system installation gauge and using the accessories
enclosed with the cartridge. This has been correctly instal
led if the tape of the stylus — viewed from above — is in the
V-shape recess of the system installation gauge. Viewed
from the side, the stylus must be in the area of the rectan-
gular recess (Fig. 7).
4, Connect the connections of the tonearm head to the con-
necting pins on the cartridge. The connections are colour-
coded
Red R right hand channel
Green RG right hand channel earth
Blue GL left hand channel earth
White L left hand channel
5. Place the mounting plate with the mounted cartridge onto
the tonearm head and — by turning the attachment screw
(10) in clockwise direction — secure this.
6. Unscrew the plastic cover on the rear of the tonearm
counterweight and screw on the additional mass enclo-
sed with the accessories.
7. Now once again carefully balance the tonearm — as described
in the section on "balancing the tonearm'
After having mounted a 1/2 inch cartridge check the height of
the playing needle above the record with the pick-up arm lift
in position Y also check that the needle lowers into the run-in
Stylus
The stylus is subjected 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 replacement
the stylus types recommended in the technical data of the
cartridge. Copied 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. To have the stylus
tested by a trade dealer, you only need to remove the stylus as
described in the following paragraph
Stylus anti-theft lock
The stylus is safeguarded against unauthorised removal by
means of a grub screw on the left hand side beside the system
attachment screw (10) on the cartridge mount (Fig. 4/S). If
you wish to remove the stylus, unscrew its grub screw and
swivel the tonearm grip (9) backwards. You can now pull out
the stylus to the front at a slight inclination.
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
Shifting 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 Z position.
3. If 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
