Audio-Technica AT-VTAZ1 Dual Purpose Azimuth and Vertical Tracking Angle Alignment and Adjustment Tool for Proper Playback Geome

Use this tool to achieve accurate tonearm height and cartridge azimuth alignment for precise tracking and proper playback geometry. VTA (vertical tracking angle) refers to the angle formed by the record surface and the line from the stylus (in the groove) to the cantilever pivot point. Incorrect VTA can lead to uneven stylus wear and potential damage to your records over time. The thickness of a record can also alter the VTA slightly. Thicker records (e.g., 180-gram vinyl) may require slightly different tonearm settings than thinner records. This also applies to phono cartridges, which may vary significantly in height. Some tonearms are equipped with a dedicated VTA or tonearm height adjustment dial that makes changes quick and easy. This is helpful if you frequently switch between records of different thicknesses or cartridges of different sizes.
