Playing vinyl is all about delicacy. LPs have to be handled with utmost care to not damage or spoil the groove on each side. Dust and the tendency of the LP to be become statically charged is a fine combination that leads to ticks or accumulation of dust at the needle tip. The latter creates distortion. In order to have the needle move just enough horizontally and with enough resistance while following the groove, the arm carrying the cartridge needs to be set up with delicate precision. Said groove is only about 0.030mm wide—at 0.16mm, a blonde hair is much thicker—and a needle tracking that groove exercises tremendous force. Literature states that a needle with a vertical tracking force or VTF of 1.5 grams exerts no less than 23.9kgf/cm² of pressure on the contact area. It's a true wonder that the groove doesn't cave under this load. Now one can imagine what a misalignment, however small, can do to a record.

Next to tracking force, there is overhang. Ideally the needle is fully tangential to the groove. But with the majority of tone arms being of the radial kind, there are only a few points during the arch movement of the needle which are actually tangent. These so-called zero points remain subject to debate as to where exactly they are. Therefore protractors for cartridge setup offer multiple geometry options.

But with VTF and overhang dialed in, we are not done yet. There is also the vertical tracking angle or VTA as the rake of the needle relative to the groove. Setting correct VTA is done by raising or lowering the tonearm where it mounts to the plinth. VTA has an influence on perceived soundstaging and tonality and its setting can be done with a software application in combination with a test record or in the old-fashioned way, by ear. In either case it is not a job done in a hurry.

The word azimuth sounds exotic but is just about channel separation. When the needle's tip doesn't sit exactly in the middle of the groove but tilts somewhat to one side, crosstalk from one stereo channel to the other occurs. Of course there are several ways to get azimuth right but they depend on the cartridge used. In many cases a small mirror will do the job.

Next in line is another exotic word, zenith. This is the alignment of the cantilever, the bar where the needle attaches to on one side and the magnets or coils depending on cartridge type (MM or MC) on the other. It often happens that the cantilever is not aligned properly to the cartridge body, hence that body cannot be used as reference to set up proper zenith or the angle the cantilever makes relative to the groove.

Adjustment is done by rotating the cartridge in relation to the head shell.
