About the Series IV.VI

### Detailed Information The SME Series IV tonearm is a well-regarded HiFi product that shares many design features with the more advanced Series V. It is constructed from a unique one-piece pressure die-cast magnesium tone-arm, which replaces conventional fabricated construction. This design provides high rigidity and allows for precise bearing adjustment before the tone-arm is fitted. The Series IV features a fine machined cartridge platform that is enamel-free to avoid interface resonance, and it uses a stainless steel cross shaft carried in a massive yoke on 10mm ABEC 3 ball races. The axis is positioned at the record mean level to minimize warp-wow effects. The tonearm also includes an anti-skate control system that operates through a tension spring and filament, with a dial that corresponds to the vertical tracking force (VTF) and has a positive OFF position. The lowering/raising control provides smooth and positive action, with adjustable height of lift. The Series IV is capable of handling cartridges in the weight range of 5 to 16 grams and supports tracking forces from 0 to 3 grams. It has an effective mass of 10/11 grams and an overhang of 17.80 mm. The SME Series IV.VI, if it exists, would likely build upon these features with potential improvements in materials or design.
