Ortofon ST-70 MC Transformer

Product Description

The Ortofon ST-70 is a moving coil (MC) signal transformer combining superior components with world-class engineering to deliver unparalleled sonic fidelity. It is equipped with Lundahl transformers encapsulated within specialised mu-metal shielding. This design ensures every musical nuance is delivered with absolute purity free from both internal & external interference; this a combination that renders the ST-70 one of the most silent yet revealing transformers in existence. The ST-70s dual mono design offers discrete circuitry for each channel eradicating crosstalk & potential distortions for cleaner clearer sonic reproduction. This enhances stereo imaging significantly providing stereo separation that conveys lifelike realism & accurate tonal balance without colouration. Incorporating premium PCB to minimise sonic degradation & maximise signal flow the ST-70 also features gold-plated RCA terminals with Teflon insulation for optimal conductivity. The unit is assembled with minimal internal wiring ensuring absolute signal integrity. Offering compatibility with most moving coil (MC) cartridges the ST-70 features internal jumpers that automatically select between two gain/impedance options. Transformers are essential for the best MC cartridge performance due to their low output requiring higher gain provided by step-up moving coil transformers or MC phono preamplifiers. Despite performing similar functions these devices differ fundamentally in function & sonic character. Step-up moving coil transformers are often preferred for their low noise & distortion properties as well as their excellent sonic integrity thanks to their completely passive operation.
