How to Set Up a Turntable Cartridge

A cartridge has five adjustments and they interact, so the order is not optional. Alignment first, then tracking force, then anti-skate, then VTA, then azimuth — because changing an earlier one invalidates the ones after it.

Of the five, exactly one comes with a number the manufacturer publishes. That fact shapes the rest of this page.

1. Overhang and alignment

A record is cut by a lathe whose cutter moves in a straight line across the disc. A pivoted tonearm swings in an arc. The two paths cannot match everywhere, so alignment geometry arranges for them to match exactly at two points on the record — the null points — and to be slightly off everywhere else.

Where those two points sit depends on the alignment geometry being used, and there is more than one in common use. They give different null points, different error curves and different overhang figures.

We are not going to print a null-point distance or an overhang figure here. Not one manufacturer whose decks we cover publishes theirs — Audio-Technica, Fluance, Music Hall and Pro-Ject all publish tracking force and none of them publishes an overhang — and a geometry constant taken from somewhere else, applied to your arm, is exactly the kind of confident-sounding wrong number this site exists to avoid.

What to do instead: use the alignment protractor that came with your turntable, or one supplied by your arm’s manufacturer for that specific arm. It encodes the geometry the designer intended, including the effective arm length — Pro-Ject publishes 218.5 mm for the Debut Carbon EVO, and a protractor drawn for a different length will align your cartridge to the wrong arc.

Practically: loosen the two mounting bolts just enough to slide the cartridge, set the stylus on the protractor’s first null point, rotate the cartridge until the cantilever is parallel with the grid lines, tighten gently, then check the second null point. Expect to go back and forth two or three times.

2. Tracking force

The one adjustment with a published number, and every cartridge we cover gives a range and a recommended value inside it.

Set it to the recommended value where one exists, and to the middle of the range where it does not. The instinct to go light to “protect the record” is backwards: a cartridge tracking below its designed force loses contact in loud passages, and a stylus bouncing in a groove does more damage than one sitting correctly in it.

Set it with a digital gauge rather than the arm’s counterweight dial. The dial assumes the counterweight is calibrated and the arm is level; the gauge measures what is actually happening at the stylus.

3. Anti-skate

A pivoted arm is pulled inward by the friction between stylus and groove, because the cartridge is offset from the pivot. Anti-skate applies an outward force to counter it.

Nobody publishes a correct value, because the required force varies with groove modulation, groove radius and the stylus profile. The convention is to set anti-skate equal to the tracking force, and that convention is a starting point rather than a specification.

Audio-Technica publishes that the AT-LP120XUSB’s arm adjusts from 0 to 4 g of tracking force and has an anti-skate control; it publishes no recommended anti-skate figure, and that absence is normal rather than an oversight.

4. Vertical tracking angle

VTA is set by the height of the arm pivot, and it changes the angle at which the stylus meets the groove wall. The standard starting point is an arm parallel to the record surface with the stylus in the groove.

Two of our cartridges give you something to work with here and the rest do not. Ortofon publishes a tracking angle of 20° for the 2M Red. Audio-Technica, Nagaoka and Grado publish no tracking angle at all.

Most decks in this price range have no VTA adjustment anyway — the arm height is fixed and the designer chose it. If yours does adjust, get the arm parallel and stop; chasing VTA by ear is a well-known way to spend an evening.

5. Azimuth

Azimuth is the stylus’s side-to-side tilt: whether the cantilever is perpendicular to the record. Wrong azimuth degrades channel separation, and channel separation is published.

That gives you the check nobody mentions. Audio-Technica publishes 20 dB at 1 kHz for the AT-VM95E, 22 dB for the VM95EN and 23 dB for the VM95ML; Ortofon publishes 22 dB for the 2M Red; Nagaoka publishes 23 dB; Grado publishes an average of 25 dB. Those are the figures the manufacturer measured with azimuth correct.

You cannot measure separation at home without test equipment, so the practical version is visual: look at the cartridge from the front with the stylus in a groove and get the cantilever vertical. Most decks offer no azimuth adjustment at all, which makes this a check rather than a task.

What the stylus profile changes about all of this

A more advanced stylus profile is less forgiving of misalignment, and the reason is contact geometry.

The same logic runs the other way and it is the useful conclusion. A better stylus is the cheapest real upgrade in vinyl — and it is only an upgrade if the alignment is right.

The order, once more

1. Alignment, with your deck’s own protractor. Changing it changes everything after it.
2. Tracking force, to the manufacturer’s published value, with a gauge.
3. Anti-skate, matched to tracking force as a starting point.
4. VTA, arm parallel, if the deck allows it.
5. Azimuth, cantilever vertical, if the deck allows it.

Then check the tracking force again, because tightening the mounting bolts and moving the arm usually shifts it slightly. The rest of the deck setup — leveling, belt, speed happens before all of this.
