Fitting a 1/2" cartridge (see page 3)
With extremely light ULM cartridges (ultra-low-mass), your
Dual record player develops outstanding reproduction capabili-
ties. In this case, the characteristicsof the tonearm are so excel-
lent that considerably heavier 1/2" cartridges also function
under optimum conditions. Proceed as follows if you wish to
fit a 1/2" cartridge.
1) If there is one on your unit, remove the removal prevention
screw (Fig. 5/"S").
2) Swivel the tonearm lift (13) backwardsand remove the ULM
cartridge from the holder (Fig. 6).
3) Slide the short holder plate (Fig. 7) approximately 5 mm
backwards and lift it off.
4) Place the long holder plate onto the tonearm (Fig. 8) in
such a way, that it lies on the surface and the back and is
pointing upwards at the front at an angleof approximately
30°. Shift the holder plate so that its large opening lies
above the round guide lug in the tonearm. Now carefully
swivel the holder plate into horizontal position and tightly
pull it forwards until you can feel it clicking into position.
5) Attach the 1/2" cartridge with the enclosed accessories to
the cartridge holder. This has been fitted correctly if the
stylus — viewed from above — is in the V-shaped recess of
the enclosed fitting template. Viewed from the side, the
stylus must be in the rectangular recess (Fig. 9).
6) Connect the cartridge holder's connection to the cartridge.
The connections have color codes:
red R right hand channel
green RG right hand channel chassis
blue GL left hand channel chassis
white L left hand channel
7) Place the cartridge holder at an angle from below onto the
tonearm head, press it fully backwards and upwards until
you can feel it clicking into position. Now carefully swivel
the tonearm lift forwards and, if you wish, lock the cartridge
and the stylus to prevent removal by screwing the described
screw.
8) Depending on requirements, screw on one or both of the
enclosed disk-shaped additional weights to the rear of the
tonearm counterbalance (1). Tum the smaller thread of the
special screw into the thread of the counterbalance. Screw
one additional weight onto the screw -with the knurled
marking on the outside — if the weight of the fitted cartridge
is no more than approximately 6.5 g and a second one if it
is heavier.
9) Now once again carefullybalance the tonearm — as described
in the section on "Balancing the tonearm".
Fitting cartridges with recess-type cartridge assembly
Cartridges with a Dual recess-type cartridge assembly can be
fitted in the same way as 112" cartridges. The cartridge holder
(Fig. 10) is designed to permit fitting of such cartridgeswithout
an additional attachment screw.
Removal prevention
Thanks to an ingenious device, the cartridge and stylus can be
easily safeguarded against unwanted removal. For this purpose,
the self-tapping screw provided with the accessories is screwed
into the hole on the left hand side of shining pin on the
holder plate (Fig. 5). At the same time, make sure that the
tone-arm lift (13) is vertical to the cartridge head center.
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. In order to have
the stylus checked, take the complete cartridge holder (remo-
val from the tonearm is described above) to your specialist dealer.
Setting the tuning anti-resonator
Your Dual record player has a tuning anti-resonator which per-
mits optimum adaption of the tonearm to the cartridge being
used. Not only Dual U LM cartridges but also conventional 1/2"
cartridges with a net weight from 2 to 9 g can be optimally
adapted with this device. For the ULM cartridge fitted in the
factory, you can find the value to be set in the data sheet of
the cartridge which is enclosed with these instructions for use.
However, this can also be determined from the following dia-
gram in the same way as for 112" cartridges.
As the example of the ULM 60 E shows, you select the own
weight of the cartridge on the horizontal scale, move vertically
upwards until you find the corresponding line for the com-
pliance and you project this point to the vertical scale from
which you can then read off the optimum tuning value.
In order to set the tuning anti-resonator, turn the scale ring in
clockwise direction until you see the determined scale value
above the pointer (Fig. 3).
The value for the Dual ULM 60 E is 7.8. It is recommended to
carry out tuning setting beforeinserting the counterbalance into
the tonearm. In this case, hold the stemwith one hand and turn
the scale ring with the other.
Note
If you turn the damping selector in the range of the wedge-sha-
ped marking to stop position, the tuning anti-resonator is safe-
guarded against transport damage.
