Lot's of mis-information on tone-arm height adjustment because of that scale. It's strictly a reference and has no bearing whatsoever on what the correct adjustment should be.
Simple procedure : w/platter stopped and a record (and slip mat if used) in place, lower the tonearm so stylus is in the groove.
Adust the height so that, when looking from the side the tonearm is perfectly parallel to the record surface (ie neither nose up nor nose down.) should look like 2 railroad tracks.
If the arm is nose up, raise the height. Nose down, lower it. Keep in mind that a stylus does not track perpendicular to the record, but at an industry standard of 20 degrees. The only time that angle is maintained is when the tonearm is adjusted correctly. Hope this clears things up. BTW as a point of reference, my test set-up 1200mk III , using an Ortofon slip mat (what else?) reads 1.6.
Additionally, that tracking angle is also dependent on the correct trackig force ...please no pennies, dimes, etc on top of the TA...just creates distortion and increase record wear. Whew, I thing that covers it.
In regards to anti-skate
Also commonly misunderstood. If you keep in mind that records were not intended to played in the reverse direction.
Under normal hi-fi use anti- skate counteracts the rotatating records tendency to make the stylus "skate" towards the label by applyng an equal and opposite force towards the outer edge. So if you had a record w/ no grooves, theoretically the stylus would not move.
However, backcuieng and scratching creates a force towards the outer edge (ie reverse play-reverse force), so if you add in the antiskate force towards the outer edge, the stylus is more likely to skip. Sooooo, if you backcue/spin or scratch , you should have antiskate set to ZERO.
This keeps an equal pressure on both walls of a stereo groove.
In normal play direction the heavier tracking forces used by DJ carts makes the antiskate less of a influence that it does in hi-fi use where typical tracking forces are 1 1/2 grams vs 3 1/2 f/DJ carts. Hope this helped. |
