How to Balance a Tonearm and Set Tracking Force

If you own a turntable with a counterweight on the back of the arm, this is the most consequential ten minutes you will spend with it. Tracking force determines how hard a diamond presses into a groove wall, and getting it wrong in either direction wears records — permanently, and faster than most people expect.

It is also completely undramatic. No tools are required, nothing can be broken by getting it wrong on the first attempt, and the whole procedure is six steps.

What you are actually setting

A tonearm is a lever balanced on a pivot. At one end sits the cartridge; at the other, a movable counterweight. Slide the weight back and the stylus end rises; slide it forward and the stylus end presses down.

Tracking forceis how hard the stylus presses down, measured in grams. Cartridge makers publish a range and a recommended figure — Ortofon gives 1.6–2.0 g with 1.8 g recommended for the 2M Red, for example. That figure is not arbitrary. It is the force at which that particular stylus, with its particular suspension compliance, sits correctly in the groove.

The reason you zero-balancefirst is that the counterweight’s numbered ring is a relative scale, not an absolute one. It only means grams once you have established the point at which the arm is weightless. Skip that and the numbers on the ring are decorative.

Why both extremes are bad

This is the part that surprises people, so it is worth stating before the procedure.

Too heavy is the intuitive failure. More force, more friction, faster wear on both the groove and the stylus. It also raises the temperature at the contact point, which does the vinyl no favors.

Too light is worse.An under-weighted stylus cannot stay seated against the groove wall when the modulation gets violent. It loses contact, bounces, and slams back — hitting the groove wall edge-on at velocity rather than tracing it. That produces audible mistracking and does more physical damage than a slightly heavy setting.

Which is why the honest advice is: set it to the published figure. If you cannot, set it to the middle of the published range. If you must err, err towards the heavy end of that range, not below it.

The procedure

Work through the six steps in the box below in order. Two of them are the ones people get wrong.

Step 2, zero-balance. The arm should float level and stay there. Nudge it gently downward and it should return to level, not sink or spring up. If it drifts persistently in one direction, the counterweight needs moving, not the ring.

Step 3, zeroing the ring. On most arms the numbered ring rotates independently of the weight it sits on. You want to turn only the ring so that 0 aligns with the index mark, leaving the weight itself exactly where balance left it. Turning both together undoes step 2 and is the single most common mistake in this whole procedure.

Anti-skate: what it is compensating for

A pivoted tonearm sweeps an arc across a record while the groove is a spiral. That geometry means the friction between stylus and groove produces a net force pulling the arm inward, towards the spindle. It is a real force with a real magnitude, and it increases as the arm moves towards the center of the record.

Uncorrected, it means the stylus presses harder on the inner groove wall than the outer one. Consequences: uneven wear on both stylus and record, and channel imbalance, since the two groove walls carry the two stereo channels.

Anti-skateapplies a small outward force to cancel it — via a spring, a magnet or a hanging weight on a thread, depending on the deck. Setting it to the same number as the tracking force is the standard approximation and it is close enough for essentially all domestic use.

The diagnostic worth knowing: if a record mistracks or distorts consistently in one channel only, anti-skate is the first thing to adjust, before you suspect the cartridge.

Checking your work

Three levels of confidence, in increasing order of effort:

• By ear. Play a busy, loud, well-mastered side. Clean tracking on the loudest passages and through the inner grooves means you are in the right territory.
• By eye. Watch the arm as it plays. It should move smoothly inward with no visible hesitation or lateral twitching.
• By gauge. A digital stylus force gauge reads the actual force at the tip and takes the factory scale out of the equation. Worth it if you change cartridges regularly.

What to do if your deck has no counterweight

Then there is nothing to balance, and that is by design rather than an oversight. Fully automatic decks like the AT-LP60X use a fixed arm at a factory-set force matched to the fitted cartridge, because their cueing mechanism needs the arm to be a constant. The force is correct; it is simply not yours to change.

The trade-off that follows — no tracking force adjustment means no cartridge upgrades — is covered in automatic vs manual turntables, and the rare deck that offers both is the Denon DP-300F.

When to redo it

Re-balance whenever you change the cartridge (different mass, different specified force), whenever you change the stylus if the new one is a different profile with a different published range, after the deck has been moved or knocked, and as a routine annual check. Counterweights creep, particularly friction-fit ones.

Note the setting somewhere — a piece of tape under the plinth works — so you can tell at a glance whether it has moved. That is the same tape we suggest for stylus dates in how often to replace a stylus.
