The supreme wall outlet, R-1.
Visual Grand Prix 2008 SUMMER
With the introduction of the R1, the category of wall outlet may now be said to have reached the stage of true maturity.
The contacts are made of beryllium copper which had previously proved its superiority in the ultra high performance M1/F1. After exhaustive testing, a combination of platinum and palladium plating, the same as used in the M1/F1, was chosen. 30% glass filled PBT proved unmatched for its thermal dissipation and vibration damping properties.
The deep emotion and exciting sound provided by the R1 is unmistakable and unforgettable.
The R-1 inherited the basic exterior design of SWO-ULTIMO series. However, responding to needs of users, it can be used for both 20A and 15A.
30% glass filled PBT is employed for its excellent machining characteristic and electrical isolation. Created under extremely high pressure, the body of the R-1 outlets is highly rigid. Its weight is increased over the previous model and improves damping ability. As a result of improved processing accuracy, the holding power of the blade is improved and unnecessary vibration is attenuated to the maximum extent possible. Moreover, its internal structural layout is that of a highly engineered load distribution.
■ Mounting flame
The 1.5mm thick gold mounting flame has preeminent strength and protects against the feedback of unnecessary vibrations from the wall. The housing is that of the R-1 made with the ultimate in design and materials.
All screws are made of stainless steel. Due to its high rigidity, there is no problem such as screw head rounded off. The maximum cable size is 5.5sq.In thorough testing, the cable has never separated from the plug by a force less than 30kg.
■ Plating Process
To complete the R-1, 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 R-1 is a combination of platinum and palladium which was 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.
The contact of the R1 is made of beryllium copper-same as the F1/M1 series using a new and high level of performance. The use of heat treated beryllium copper insures mechanical integrity and high conductivity. It is 1.0mm thick and 6.0mm in width, reducing vibration at the point of contact with no loss of signal transmission.
