If you try adjusting the anti-skate with a groove less
record, you will ruin the twist in the tonearm wire and void
your warranty. Do this with the mechanical anti-skate if
you want that much anti-skate.
•
If additional anti-skate is needed you can go to the mechanical anti-skate supplied.
Setting the Tracking Force and Tonearm Height
•
Tracking force is adjusted by moving the tonearm counterweight forward and back on its
shaft. If your cartridge is heavy and the counterweight is all the way back, you can order a
heavier weight from your dealer.
•
The JMW Signature Tonearm does not have a built-in tracking force gauge. We recommend
that you use the Shure Stylus Force Gauge or good digital gauge. Place the gauge on the
platter and raise or lower the arm so it is parallel to the platter when sitting on the record.
Only when the arm is parallel to the platter will you get an accurate VTF reading.
•
Follow the gauge instructions and set the tracking force according to the cartridge
manufacturer’s recommendation. We recommend always going to the high side of tracking
force. High frequency vibrations on a light-tracking cartridge can cause more damage to the
grooves of a record than running a cartridge at a heavy setting. Always go 1/10
th
gram
higher than the maximum recommendation.
•
To adjust the arm height, loosen the setscrews on the base of the arm assembly and turn the
adjustment wheel above the base. When the arm is at the desired height, tighten the screws.
If you put a 5” X 7” lined index card next to the arm when it is on the record you can set the
height very accurately parallel to the record. That should be your zero starting point for
tuning VTA.
Setting the Azimuth
•
Set a drinking straw into the groove behind the mounting screws on the tonearm headshell.
The straw should be parallel to the record.
•
The ring around the bottom of the bearing assembly on the arm wand (shown below) is called
the azimuth ring. Rotating the ring will level the arm and give you a 90 degree azimuth
setting. Turn the flat side of the ring towards the side that is lower.
