Ortofon ST-7 MC Transformer ORTAST7A1200225

The Ortofon ST-7 is an MC transformer that serves as a useful asset for Moving Coil (MC) cartridge owners. MC transformers are designed to maximise the efficiency of both the cartridge and the phono stage. As a result of their design MC cartridges exhibit a lower output than Moving Magnet cartridges. This necessitates a higher gain from a phono stage for standard listening levels on your audio system.Unlike phono stages which have a steady resistive input impedance MC transformers possess an input impedance that varies with frequency. These transformers are passive thereby minimising the effects of external electrical forces on the cartridges low output signal. The unique design of the transformer allows it to amplify the MC output level while reducing harmonic distortion as the frequency increases creating a purer electrical signal and enhancing sound performance. Encased in robust housing with a compact and stylish design the ST-7 is supported by four rubber feet to minimise unwanted vibrations. Intricate internal wiring and gold-plated terminals ensure optimal signal transmission. An innovative sandwich winding structure enhances high-frequency response and delivers clear open sound across all frequencies. The dual-mono design with individual shielding for each channel improves imaging and minimises environmental noise impact. Perfectly compatible with MC Quintet Series SPU Classic models and SPU #1 models the ST-7 transformer is a valuable addition for vinyl enthusiasts seeking the best possible sound.
