What is the VTA on a turntable?

The Vertical Tracking Angle (VTA) describes the vertical angle at which the needle of the pickup lies in the record groove. Ideally, this angle should match the cutting angle of the original master record - typically around 20 degrees.

If the angle is not set correctly, this can have a noticeable effect on the frequency balance, spatial imaging and scanning accuracy.

Why is the correct VTA setting so important?

An incorrect VTA can lead to overemphasis of the treble or bass, make the sound imprecise or aggressive and impair channel separation. Especially with high-resolution systems or MC cartridges, a VTA deviation of just a few degrees can result in audible losses.

How do you set the VTA correctly?

1. adjust the tonearm height

The VTA can usually be adjusted via the height of the tonearm at the bearing base. The aim is to align the tonearm as parallel as possible to the record surface.

2. use a test record

Ideally, you should use a 180g vinyl test record to try out different arm heights. This is because different record thicknesses automatically influence the VTA.

3. sound evaluation by listening

The final fine-tuning is done "by ear": voices, cymbal sound and S-sounds are good references for assessing the naturalness and balance.

What is the Fozgometer - and how does it help with tuning?

The Fozgometer from Musical Surroundings is a precision measuring device for azimuth control, i.e. the lateral alignment of the pickup. Indirectly, however, it also helps with VTA adjustment by making the channel balance visible.

This is how the Fozgometer works:

• A special test signal (e.g. from the Adjust+ record) is played through both channels.
• The Fozgometer measures the difference in level and indicates whether one channel is too dominant.
• A perfect balance can be achieved with small adjustments to the azimuth and - if necessary - to the VTA.

Important: An incorrect VTA can lead to an incorrect azimuth evaluation. For this reason, the VTA should always be roughly adjusted first before the channel balance is fine-tuned.

Conclusion: Perfect sound starts with the right angle

Anyone who values audiophile reproduction should not leave the VTA to chance. With a little patience, listening comparisons and, if necessary, support from measuring devices such as the Fozgometer, you can achieve the optimum geometry of the pickup - with noticeable improvements in sound quality.

Our tip: Adjust regularly - especially when changing cartridges or with records of unusual thickness. Because precision pays off - in every bar.
