I.Fine azimuth Adjustment
Using a Dual Trace Oscilloscope
Even if the cartridge body is square there is no guarantee that the generator within the
cartridge is at the correct angle to the cartridge body. With an oscilloscope and test
record which has channel separation tracks, one can measure how much of the signal
from one channel crosses over to the other. This is called crosstalk and is always
present to some extent, but it should be equalised.
Azimuth affects channel separation. If the cartridge is tilted to one side the separation
will be very good on one channel but very bad on the other. Good sonic results are
gained when the separation is equal. Be sure to measure crosstalk only not output.
Readjustment of Tracking Force
It will now be necessary to readjust the tracking force. This can be done using scales,
if available or by rotating counterweight back until tonearm is balanced (with stylus
guard off) and applying the required tracking force as previously described. (IV C) Fix
counterweight as described.
Final VTA Correction
Once the azimuth has been corrected the VTA should be checked. For optimum
performance recheck VTA after 30 - 40 playing hours. This may be necessary due to
‘settling’ of cantilever suspension in the cartridge, the amount of which varies
according to the make of cartridge.
J. Cueing Device Adjustment
Should you find that in the ‘up’ position the cartridge is too high or too low above the
record then the cueing device can be raised or lowered. (Fig. 25) This can be done
simply by using Allen key 1.5 mm.
1. Insert key into screw on left side of arm rest.
2. Release screw, raise or lower device and retighten.
NOTE: The cueing device may lift slightly as the screw is retightened. Do not
overtighten as this may cause the cueing device to stick in the ‘up’
position. Should this occur, slightly release the screw.
