When a signal flows through a conductor, electric and magnetic fields are simultaneously produced. They are bound up together so inextricably that if you want to change either the electric or magnetic field only, you need to also change the other. Every effort that were done to shield “electric signals” from electromagnetic effects turns out to be unsuccessful because of its nature.
Musical events occur when instruments stir up acoustic vibrations through the air. The vibrations consequently turn into electric signals, and the electric signals are transformed to other data forms, which can be stored in various storages. We always reverse the field to reproduce musical events. Upon several recording and reproduction of musical events using various systems and cables, we have arrived at the final destination—we should keep magnetic field alive at some extent to have an exact rendering of music’s real sound. Complete shielding is not the panacea; rather it is definitely like pesticide to live music.
FMCF technology makes it possible for us to come closer to real music, through which we can “hear” the picture and “see” the sound of music.
