Ortofon STYLUS Q.BERT – Spherical Replacement Stylus

Overview:

The Ortofon STYLUS Q.BERT is a spherical replacement stylus for compatible OM and Concorde Q.BERT cartridges. It supports scratching, back-cueing, and demanding turntable techniques. Its spherical profile provides 90 μm tracking ability, while the 11 mV output delivers a strong signal. Additionally, its focused sonic response helps reduce surface noise and emphasise scratching during performance.

Key Features:

•    Scratch and Back-Cueing: Designed for demanding turntablism, it helps DJs maintain control            during expressive techniques.
•    Spherical Stylus Profile: The R 18 μm tip follows record grooves effectively during intensive                turntable movements.
•    90 μm Tracking Ability: Strong groove tracing helps maintain reliable tracking throughout                   demanding scratch and back-cueing sessions.
•    Ultra-High 11 mV Output: The high output delivers a strong signal for energetic DJ and                            turntable applications.
•    Focused Sonic Response: A subdued high-frequency response helps minimise surface noise            from worn vinyl.
•    Accentuated Mid-Range: The enhanced mid-range gives scratching a more prominent position        within the sound stage.
•    Flexible Tracking Force: A 2.0-4.0 g range lets DJs adjust tracking for different                                          performance requirements.
