In order to provide a wide range of analog disc sound expressions to customers, the developed MC cartridge P-3 (released in year 2005) making good use of high technology is now piling up the results as the cartridge’s standard model for this class until support is provided.


Reviewing the Magnetic Circuit

Even without illustrating the speakers, for the audio devices having an magnetic circuit is known from experience that the magnetic material plays a large effect on the sound quality and due to repetitive test hearing, the following materials have been selected finally.

This unit’s magnetic circuit composed with permendur has the highest retentivity Hc among magnetic materials and could structure a stable magnetic field.

Continuing the Structure of Resonance Free, Vibration Free.

For this unit, the low impedance MC cartridge is developed having the main concept of resonance and vibration free, the accuracy is maintained and in order to reach an ultimate exclusion of vibrations besides the power generator, absolutely no pre-shaped objects were used but all parts were processed with precise carving.
In addition, for the base that establishes a mechanical earth, a DLC (Diamond Like Carbon) processing (sealed by USA) is done on the duralumin carved material and a surface hardness next to diamond is raised at Hv=3000 or more and actualized a case structure excelled in high rigidity and periodic damping.


Introducing High Sound Quality Material

We continue to have a light and highly rigid pure-boron introduced in the cantilever, a generating circuit due to 6N non-oxide copper wire, and a high sound quality element proved on P-1 and P-3 of pure iron coil bobbin, etc having a high density of saturated magnetic flux.
