Headshell alignment block used for VTA and azimuth alignment (vertical tracking alignment)
We can adjust arm height in an effort to duplicate the cutters path through the vinyl disc is to set the angle of the cantilever.
This angle, referred to as the vertical tracking angle or VTA, is changed by modifying the height of the tonearm relative to its base.
Within the limits of your vision to the surface. Once a rough azimuth adjustment is found visually, it can be fine-tuned via measurement.
Material: Acrylic high definition, high transparency, easy to use
