Turntable Setup: Tracking Force, Anti-Skate & Alignment

A turntable straight out of the box — or fresh from a thrift store — needs setup before it sounds its best. Tracking force, anti-skate, and cartridge alignment are the three adjustments that determine whether your records sound clean and detailed or distorted and prematurely worn. This guide covers all three, plus the tools you need to do it right.

Tracking Force

Tracking force is the downward pressure the stylus applies to the record groove, measured in grams. Every cartridge has a recommended tracking force range specified by the manufacturer — typically between 1.0 and 3.0 grams depending on the design.

Too little tracking force and the stylus skips, mistraces, and distorts. Too much force accelerates record and stylus wear without improving sound quality. Set tracking force to the middle of the manufacturer's recommended range as a starting point, then adjust by ear if needed.

Setting Tracking Force

First, balance the tonearm so it floats level — the counterweight on the back of the tonearm adjusts until the arm hovers horizontally without moving up or down. This is your zero point. Then dial the counterweight forward (toward the headshell) by the number of grams your cartridge requires. If your cartridge specifies 1.8 grams, turn the graduated ring to 1.8.

Verify with a digital gauge. Place the gauge on the platter surface (or a record), lower the stylus gently onto the gauge platform, and read the display. Adjust the counterweight until the gauge reads your target force. The graduated markings on most counterweights are approximate — the gauge gives you the real number.

Anti-Skate

As the tonearm tracks inward across a spinning record, geometry creates a force that pulls the stylus toward the center of the record. Anti-skate applies an opposing force to counterbalance this inward pull, keeping the stylus centered in the groove for equal contact with both groove walls.

Set anti-skate to match your tracking force as a starting point. If tracking force is 1.8 grams, set anti-skate to 1.8. Then fine-tune by ear: play a record with vocals and listen for channel imbalance or distortion on inner grooves. If the right channel distorts or sounds louder, increase anti-skate slightly. If the left channel is problematic, decrease it.

Cartridge Alignment

A phono cartridge must be aligned so the stylus sits perpendicular to the groove at specific points across the record surface. Because a pivoting tonearm swings in an arc (not a straight line), the cartridge can only achieve perfect tangency at two specific radii on the record. Alignment protractors set these two null points for minimum tracking error across the entire record surface.

Using an Alignment Protractor

Download a printable Baerwald or Stevenson protractor (both are freely available as PDF files) and print at 100% scale on standard paper. Place the protractor on the platter spindle and lower the stylus onto the inner null point grid. The stylus tip should sit exactly on the crosshair, and the cartridge body should be parallel to the grid lines.

If the cartridge is not parallel, loosen the headshell mounting screws slightly and rotate the cartridge body until it aligns. Tighten the screws and check the outer null point. You may need to adjust overhang (how far the cartridge extends beyond the headshell) by sliding the cartridge body forward or backward in the headshell slots.

This process takes patience — small adjustments at the inner point affect alignment at the outer point and vice versa. Go back and forth between the two points until both are as close to perfect as possible, then lock everything down.

Azimuth and VTA

Azimuth is the left-right tilt of the cartridge when viewed from the front. The stylus should sit perfectly perpendicular to the record surface. Most tonearms do not have an azimuth adjustment; headshell design handles this. If your cartridge appears tilted, check that the headshell is seated properly.

VTA (Vertical Tracking Angle) is set by adjusting tonearm height so the tonearm tube is roughly parallel to the record surface when the stylus is in the groove. Taller cartridges may need the tonearm raised; shorter ones may need it lowered. Not all turntables offer VTA adjustment — on fixed-height tonearms, the cartridge designer has accounted for a typical setup height.

Level the Turntable

Before touching any tonearm adjustments, make sure your turntable is level. Place a small bubble level on the platter (with the platter mat removed) and check both front-to-back and side-to-side. An unlevel turntable causes uneven tracking force across the record surface — the stylus presses harder on one side of the groove than the other, increasing distortion and accelerating wear on one channel.

Most turntables have adjustable feet for leveling. Turn the feet individually until the bubble centers. If your turntable does not have adjustable feet, shim under the base with thin cardboard or rubber pads until level. The surface the turntable sits on matters too — a wobbly shelf or an uneven desk will transmit vibrations into the tonearm. A solid, heavy surface (thick wood shelf, concrete slab, or granite cutting board) provides the best foundation.

Selecting the Right Protractor

Several alignment geometries exist, each optimizing tracking error at different points across the record. The three most common are Baerwald (also called Lofgren B), Stevenson, and Uni-DIN. Each places the two null points (where tracking error is zero) at different radii on the record surface.

Baerwald is the most widely recommended for general music listening. It minimizes the average tracking error across the entire playing surface, providing consistently low distortion from outer to inner grooves. Stevenson minimizes tracking error at the innermost grooves — the most distortion-prone area — at the cost of slightly higher error on outer grooves. This can be preferable if inner-groove distortion bothers you more than overall average distortion.

For practical purposes, the difference between alignment geometries is subtle. Using any protractor correctly is far more important than choosing the "best" geometry. A perfectly executed Baerwald alignment and a perfectly executed Stevenson alignment will both sound excellent. A sloppy alignment using either geometry will sound poor. Precision of execution matters more than geometric theory.

Tonearm Height and VTA Adjustment

Vertical tracking angle (VTA) is set by adjusting the tonearm height so the arm tube is approximately parallel to the record surface when the stylus is in the groove. On turntables with VTA adjustment (a locking collar or grub screw on the tonearm pillar), loosen the lock, raise or lower the arm to level, and re-lock.

The VTA sweet spot depends on the cartridge design. Most cartridge manufacturers design for a 20-degree stylus rake angle, which corresponds to a roughly level tonearm. Raising the back of the tonearm (tilting the cartridge forward) can add brightness and detail. Lowering the back (tilting backward) can add warmth and reduce sibilance. Adjust in small increments and listen for the most natural vocal reproduction.
