In creating the ST.150/STR8.150, Stanton went back to basics and re-engineered everything. These "no nonsense" turntables have everything professional DJs need and nothing they do not. That is why the ST.150 (standard S shaped tone arm) and STR8.150 (skip-proof straight tone arm) are built primarily with quality in mind. Both models offer durable construction designed to minimize feedback, industry-leading torque motor - up to 4.5-kilogram-force per square centimeter, and an ultra-stable platter and tone arm. Other features include key correction, reverse, up to 50% pitch adjustment, and S/PDIF digital outputs.
