Cartridge Installation - Oracle PRELUDE TONE ARM Owner's Manual

Cartridge Installation

Select the right screws for mounting your cartridge. Remember that steel screws are 2 ½
-
the weight of aluminum screws, and unnecessary increase in mass will have an adverse
effect of warp riding.
Before installing the cartridge make sure that its stylus protector is firmly in place. Tighten
-
the screws just enough so that the cartridge can still be moved.
Note: We do not recommend the use of any puttu or damping compound between the
-
cartridge and head shell, since these materials will not allow a firm enough coupling.
Retrieve the appropriate tonearm counterweight from the packaging and slide it onto the
-
rear of the tonearm, which its bevelled side facing the head shell.
Note: Hold the tonearm pillar firmly during this operation to prevent damage to the
-
bearings. Make sure that you have removed the stylus protector before setting the
downforce.
Using your stylus pressure gauge as a reference slide the counterweight forward or
-
backward until the downforce is within the range as specified by the cartridge
manufacturer.
First remove the tapered washer and place the calibrator disc on the mat.
-
Cue the arm down so that they stylus at the centre of the black reflective square on the
-
disc.
Note: Looking from the side of the cartridge there should be an even angle reflection on
-
each side of the stylus.
If this is not the case, loosen the VTA tower-locking screw.
-
Rorate the calibrated know clockwise to raise it. Each mark on the calibrated knob
-
represents 0,001" or vertical displacement.
Note:With the VTA tower locking screw loosened this adjustment can be performed while
-
the record is playing so that the optimum setting can eventually be judged by ear.
Cue the tonearm and set is down such that the stylus tip rests precisely in the indentation
-
at the centre of the adjustment grid. Make sure that you use the grid marked "Prelude" and
not the one marked "Finale".
Move the cartridge forward and backward in the head shell until the cartridge body and the
-
sides of the head shell are lined up with the grid when viewed from above with the stylus
resting in the indentation.
