Ortofon OM PRO S

Core Performance Features

• Rugged Entry-Level Workhorse: Built to handle the everyday rigors of DJing, offering high durability and reliable tracking across all music genres.

• Low-Wear Spherical Diamond: Features a precision spherical diamond tip (R 18 µm) that sits higher in the groove, preserving vinyl life during repetitive backcueing and practice routines.

• Balanced Sound Reproduction: Delivers an even, musical frequency curve across low, mid, and high frequencies without overly boosting or cutting particular bands.

• Standard Half-Inch (1/2") Mount: Mounts to standard headshells (such as the Ortofon SH-4 or Technics headshells), allowing precise adjustment of overhang, tracking angle, and tonearm balance.

• Removable Weight Plate: Includes Ortofon's classic brass top weight plate, giving users the choice between a lighter 2.5 g body or standard 5.0 g configuration to match various tonearm mass requirements.

• Wide Compatibility: Works cleanly with both analog vinyl pressings and digital vinyl systems (DVS) like Serato DJ Pro, rekordbox DVS, and Traktor Scratch.
