PrimaryControl is presenting a new bearing technology, the FCL is the world’s first field coil loaded unipivot tonearm. This technique provides high torsional stability and a low moment of inertia for the tonearm. Bearing chatter, caused by energy transfer in the unipivot bearing, is eliminated. The field coil also functions as a sensor for unwanted torsional movements. The constant current source regulator provides the power for the field coil. It keeps the current and the magnetic field under all circumstances stable.
In combination with the newly developed ultra-low resonance arm wand, the PrimaryControl FCL leads to fine detail reproduction and a sonic performance unmatched by any other unipivot tonearm design.
