Το Oyaide P-004e ειναι βυσμα Schuko με χαλκο βηρυλλιου (beryllium copper) επιπλατινωμενους και επιπαλλαδιωμενους αγωγους. Made in Japan.
We designed the M1/F1 as our flagship model, making no compromise. The  result is a sound that is powerful, dynamic and highly sophisticated.  The M1/F1 represents a major step forward in cutting edge technology  having inherited and improved upon the advanced technologies of our P/C  series.
Based on the technology of M1/F1, we have achieved to create P-004/C-004  as its cost-performance by integrating the features of M1/F1 and P/C  series.
As well as other P/C seires audio plugs, the core of P-004/C-004 is  composed of the selection of materials, plating technology, and  usablity.
Inheriting the most core factor of M1/F1, the contacts of P-004/C-004  are made of beryllium copper which insures mechanical integrity and high  conductivity. The plating is also same as M1/F1 that is a combination  of platinum and palladium which was selected after repeated listening  tests.
The body is made of 30% glass filled PBT which has excellent  machine-ability and provides superior electrical isolation. And the  outer cover of P/C series is made of PC(PolyCarbonate) for its rigidity  and hardness. In addition, its "Black-Diamond" color of P-004/C-004  outer cover represents its emotional and exciting sound.
Contacts
As well as the Premium Series, M1/F1, we employed beryllium copper for  its superior conductivity and excellent mechanical characteristic.
The contacts of P-004/C-004 are heat treated to insure electromechanical  integrity. The 1.0mm thick and 6.0mm wide contacts provide maximum  contact area, have more than 8kg of holding power and reduce vibrations  at the point of contact with no loss of signal transmission.
Plating
The manufacturing process is started from foundation coating. The  material which was punched out as a part is polished by hand piece by  piece after machined barrel-polishing.
The plating of the P-004/C-004 is a combination of platinum and  palladium which were selected as a result of repeated listening tests.  The inner platinum layer is 0.5 microns thick and the outer palladium  layer is 0.3 microns thick.
GF PBT body
30% glass filled PBT has excellent machine-ability and provides superior  electrical isolation. The highly rigid body of the P-004/C-004  effectively attenuates high-speed vibrations. All screws, which were  originally designed for P/C series, are made of highly rigid stainless  steel which is non-magnetic substance. Moreover, the cable cannot be  separated from the plug by a force less than 30kg, a significant safety  feature.
Outer Cover
The outer cover of P/C series is made of PC(PolyCarbonate) for its  rigidity and hardness. It helps to attenuate tiny vibrations in quick  response and reduce distortions by its superior mechanical strength.
