from an average reading. In practice this has no eff ect
on performance and is also common among certain
unipivot designs with very low friction bearings.
Connecting the arm
FIT THE ARM CABLE CLIP
For best performance the arm cable should be
supported by a cable clip screwed into position
underneath the plinth - leave a slight droop on it so
that it isn’t “tight”. Clipping the arm helps prevent
vibration feeding into the arm.
CONNECT THE ARM TO YOUR PHONO
STAGE / AMPLIFIER
Th e bullet phono plugs are usually a very tight fi t to
your phono stage sockets. To avoid possible damage
to your amplifi er sockets, the manufacturers advise
that you should heat the bullet plugs with a hair dryer
(or similar) to soften them slightly till they fi t easily
onto your phono stage / amplifi er phono sockets.
Once fi tted, you do not need to reheat the plugs in
future as they will maintain the correct tightness.
Th e earth lead should be connected to the earth of
your phono stage, pre-amplifi er or amplifi er. Th is
earth lead is best separated slightly from the arm
signal leads so do not wind it around them for best
performance. Avoid pulling the external wires at the
base of the arm as they are not indestructible and
can become detached if excessive force is used to
manipulate them.
If you have XLR plugs , you will not get both plugs
through the mounting hole for the arm. Th e hole is
too small to allow the 2nd plug to go through as the
1st cable wire takes up space.
For this reason we normaly fi t only one XLR plug
and leave you to fi t the other. Full instructions on
how to fi t the other XLR are available on our web site
- see top navigation bar, click “general information”
then “technical support” on the drop down list.
Making the dual points
operational
Th e transit bolts shown in illustration are critical,
to prevent damage to the bearing points in transit.
Gently remove these to make the arm operational.
Keep the bolts and nylon washers in a safe place.
Th
ese MUST be replaced whenever you send the
arm by post or courier as the boxes can get severely
thrown around. Damage to the points occurs, unless
the transit bolts are in place.
CHECK THAT ALL IS WELL - Th e stylus down
force should be consistently accurate to within plus or
minus 0.06 grams from the average (i.e = 0.12 gram
total variation). Higher deviations indicate that the
bearing might be damaged or incorrectly adjusted.
Th e bearing freedom of movement should be checked
by measuring the stylus down force over a succession
of 10 or so movements of the arm into the arm clip
and then onto a stylus force gauge. Th
e force gauge
should read consistently to within plus or minus 0.06
grams from an average over the 10 measurements if
all is well.
It is best to use a digital force gauge for this as a
“balance” type can give inconsistent readings with
errors of up to 0.5 grams .

Remove and keep for future use
DO NOT TAMPER WITH ANY OF THE GRUB
SCREWS IN THE YOKE - Th
ese are precisely set up
at factory and any interference will probably end up
with damage to the pivot points or bearings that don’t
work properly.
