Το Oyaide C-004 ειναι βυσμα IEC 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.
