Premounted SH-4 Black Headshell: The OM PRO S comes mounted on the SH-4 Black headshell for convenient installation. This configuration makes mounting and replacement straightforward on compatible S-shaped tonearms.

Universal Mount: The universal mount fits a wide range of S-shaped tonearms. Therefore, DJs can use the cartridge across compatible turntable setups without complicated mounting procedures.

Baerwald Alignment: The premounted configuration provides correct Baerwald alignment with most tonearms using a universal mount. This helps simplify setup and supports accurate cartridge positioning.

Spherical Stylus: The spherical stylus features an 18 μm tip radius. Its design helps minimise scratching while supporting consistent groove contact during regular DJ use.

Solid Cantilever: The solid cantilever handles hectic activity around the turntable. Consequently, the cartridge provides a durable option for DJs who regularly perform active vinyl sessions.

Reliable Tracking: The OM PRO S achieves 70 μm tracking ability at 315 Hz. Its 7 μm/mN dynamic lateral compliance supports the specified tracking characteristics during playback.

4 g Recommended Tracking Force: The cartridge operates within a 3–5 g tracking force range. Ortofon recommends a 4 g tracking force for the specified operating setup.

Replaceable Stylus: The OM PRO S uses the Stylus PRO S as its specified replacement stylus. This gives DJs a dedicated replacement option when the stylus requires changing.

All-Round DJ Performance: Ortofon describes the OM PRO S as a consistent performer and all-rounder. Its design suits a variety of everyday DJ and vinyl applications.
