Ortofon OM SCRATCH ON SH4

Core Performance Features

• Factory Pre-Mounted & Aligned: Ships pre-assembled and calibrated to standard 52 mm Technics overhang geometry, allowing immediate plug-and-play connection to any SME bayonet socket.

• Reinforced Scratch Cantilever: Built with an extra-durable suspension and stiff cantilever assembly engineered to resist skipping during rapid backcueing, hard cuts, and aggressive finger manipulation.

• High-Output 7 mV Generator: Delivers a hot 7 mV signal to DJ mixer phono preamps, providing strong dynamic range, high signal-to-noise ratio, and pronounced low-end punch on club sound systems.

• Groove-Preserving Spherical Diamond: Features a precision spherical diamond tip that sits higher in the groove, minimizing record burn and premature groove wear during repetitive cue-point scratching.

• Ergonomic Long Finger Lift: The SH-4 aluminum headshell features an extended, curved finger lift that gives DJs steady, slip-free control when needle-dropping in low-light booths.

• DVS & Real Vinyl Tracking: Fully optimized for clean signal tracking across both traditional analog vinyl and timecode control records (rekordbox, Serato DJ, Traktor Scratch).
