A stylus crafted for DJ demands within the Ortofon range
The Scratch A belongs to the realm of DJ performance solutions, where priority is given to groove retention and consistency in real-world conditions. Its neon red aesthetic is not just a visual choice: it facilitates immediate identification of the stylus tip and diamond position, a real advantage when the action is fast and lighting changes.
Who is it for, and in what usage contexts?
This stylus is primarily aimed at turntablists, battle DJs, and scratch enthusiasts who require solid tracking and reliable response during intense manipulations. It is also suitable for club or event DJs seeking a responsive and powerful cartridge, especially when the set involves technical gestures, aggressive transitions, and frequent back-cueing. In the studio, it remains relevant for capturing the energy of scratching and achieving stable playback on heavily stressed passages.
Features and innovations
The Scratch A focuses on an effective combination: spherical diamond for tolerant and robust playback, reinforced suspension for better stability under high tracking force, and high output to properly drive the phono preamp and gain presence. The sound reproduction is designed for DJing, with powerful bass and extended highs, to maintain impact on a sound system while preserving definition on attacks and the typical handling noises of scratching.
