ZYX ULTIMATE EX ASTRO

Put simply, a moving coil type cartridge can be described as a kind of transducer (a device that converts energy from one form to another).

It induces a current, proportional to the vibration speed in the coil. This is arranged in the direction perpendicular (set off at 90 degrees) to the magnetic field line, by the mechanical movements created by the stylus tip tracking the grooves of the record. This creates and transmits a sound signal. It can be called a converter.
