Premounted SH-4 Headshell: The OM Scratch White arrives mounted on the blue SH-4 headshell for convenient installation. This ready-to-use configuration supports direct mounting and replacement on compatible S-shaped tonearms.

Universal Mount Compatibility: The universal mount fitting works with a wide range of S-shaped tonearms. Therefore, DJs can integrate the cartridge into compatible turntable setups more easily.

Spherical Stylus: The spherical stylus uses an 18 μm tip radius for consistent groove contact. This design supports demanding DJ techniques, including scratching and back-cueing.

Reinforced Rubber Suspension: The reinforced rubber suspension supports increased tracking ability during demanding vinyl performance. Consequently, DJs can work confidently with higher tracking forces.

High Output: The cartridge produces a 7 mV output voltage at 1 kHz and 5 cm/sec. This high-output design provides a strong signal for suitable phono equipment.

Baerwald Alignment: Ortofon specifies correct Baerwald alignment with the major part of universal-mount tonearms. This feature helps simplify cartridge positioning during compatible installations.

Replacement Stylus: The OM Scratch White supports the Stylus MFS as a replacement stylus option. This allows DJs to maintain the cartridge when the stylus requires replacement.
