How to Adjust Cartridge Azimuth
- Move the cartridge to the middle of the record.
- Lower the tonearm so the stylus rests on the record surface.
- Place the ruler in front of the cartridge and check whether the cartridge aligns with the vertical centre line of the grid.
- Verify that the outer contour of the cartridge aligns evenly with the grid lines.
How to Adjust VTA (Tonearm Balance)
- Move the headshell to the middle of the record.
- Lower the tonearm so the stylus rests on the record surface.
- Place the ruler alongside the tonearm and check whether the arm runs parallel to the horizontal lines on the ruler.
- If it is not parallel, adjust the VTA by raising or lowering the tonearm height accordingly.
⚠ Important: Always ensure the turntable platter is NOT spinning when making any adjustments.

Frequently Asked Questions
Q: What is VTA and why does it matter for my vinyl record player?
A: VTA (Vertical Tracking Angle) refers to the angle at which the tonearm and stylus meet the record surface. Correct VTA alignment ensures optimal stylus contact with the record groove, resulting in better channel balance, improved frequency response, and overall cleaner audio reproduction from your LP vinyl setup.
Q: What is azimuth adjustment on a phono cartridge?
A: Azimuth refers to the rotational angle of the cartridge on the horizontal axis — essentially whether the stylus is perfectly perpendicular to the record groove. Proper azimuth alignment maximises channel separation and minimises crosstalk, giving you a more accurate and immersive stereo soundstage.
Q: Is this ruler compatible with all tonearms and cartridges?
A: Yes — this acrylic adjustment ruler is a universal measurement aid compatible with the vast majority of phono tonearms and cartridges used on 33 and 45 RPM turntables. Its clear grid lines allow you to visually assess alignment regardless of cartridge shape, with the guide noting that for irregularly shaped cartridges you estimate proportional alignment.
Q: Do I need to remove the film before using the ruler?
A: Yes. The ruler ships with a protective film applied to the acrylic surface. Peel this film off completely before use to ensure the grid lines are fully visible and clear for accurate alignment readings.
