Compact and stylish, the Ortofon ST-7 is a step-up transformer with compact dimensions designed to optimize the integration of low output moving coil (MC) cartridges with internal impedance between 2 and 60 ohms in systems equipped only with circuitry for cartridges. moving magnet (MM).

A dual monophonic design, with windings mounted in a sandwich structure specially developed by Ortofon and supported by four treated rubber feet, the ST-7 also includes individual permalloy shielding for each channel to improve sound imaging and reduce noise. influence of environmental noise. With a gain of 24 dB at 1 kHz and a frequency response curve that spans from 15 to 45,000 Hz, Ortofon 's new transformer will enhance both the dynamics and micro-data analysis capabilities of the best analog sources.
