ADJUSTMENT OF THE AZIMUTH
The azimuth is the correct vertical angle of
the diamond needle into the grooves of the
record, i.e. seen from the front, the diamond
must be exactly perpendicular to the record.
The easiest way to check this is to use a mirror
onto which the pick-up head is lowered. The
pick-up system and the image must form a line
Fig. 14 Fig. 15
without any kinks.
Alternatively, it is advisable to use a transparent stencil with a line grid, through which a slanted position of
headshell and pick-up becomes directly visible. You may also be able to use a commercially available set
square for this purpose.
To correct a possible deviation from the correct position, the tone arm can be turned.
To do this, loosen the cover of the arm base (Fig 14) with a small flat-blade screwdriver and then slightly loos-
en the cross-head screw (Fig 15) (1) located centrally underneath.
CAUTION: please only loosen slightly, never unscrew!
After loosening the screw, the arm tube can be turned a few degrees in both directions. When doing so, al-
ways check the current position with a mirror or template.
Make sure never to move the arm lengthwise, but only sideways.
