The Oyaide's original "OR-800" speaker cable was launched
25 years ago and quickly established Classic status in Japan. It is composed
of high-purity copper litz wire and star-quad structure, is one of the
pioneers of high-end speaker cable and has been popular for decades.
In 2004, it is remodeled to "OR-800 Advance". Equipped with
the original Y-terminals, it improved the ability to portray music scale
emotionally and sensitively.
Finally in 2008, the long-awaited banana plug version, "OR-800 B",
High quality SRBN banana plug
So far, a banana plug is known as inferior to spade plug in sound quality
due to its low adhesiveness in spite of its user-friendliness. So, we
aimed at producing the high-quality banana plug, with maintaining both
high sound quality and usability. As a result, "SRBN" banana
plug was created in 2008.
Highest manufacturing standard
The original banana plug of "OR-800B" is designed based on "SRBN"
in order to accept very thick conductors of OR-800.
Same as the "SRBN", it is made of deoxidized phosphor bronze which
is used in many contacts due to its excellent springiness and electric property.
The contact tip is slit up in a cross shape and divided in quarters to ensure
the maximum contact area and is designed to be fit tightly into terminals when
it is inserted.
The size was determined based on WBT's speaker terminals, but it can be fit
in any terminals. After more than ten times of repeated cut and try, SRBN was
exquisitely-designed to be inserted smoothly and not to be come off easily.
High purity Litz wire of conductor
For the conductor, almost four hundreds of very thin wires made of OFC (Oxygen
Free Copper) is installed in star-quad structure. Its litz wire structure prevents
deformation among the wires because of enamel coating (UEW) on the surface and
prevents loss of high-frequency characteristic by skin effect.
High sound quality Pb free soldering
The original banana plug and the conductor of the cable is soldered by high-quality
Pb free solder which was selected based on our years of experience. It has well-balanced
sound quality and achieves to get rid of the turbidity of the sound by soldering
to the maximum.
Inner cotton thread insulator
Outer insulator which is made of cross-linked polyethylene is set around inner
Due to the both insulator which has different degree of hardness, it achieved
to prevent negative effect by sympathetic vibration. Moreover, cross-linked
polyethylene has a quarter of permittivity compared to common PVC.
Outer polyethylene insulator
The outer insulator is made from cross-linked polyethylene. This strengthens
insulation property of OR-800B and helps to prevent from adding coloring to
sound sources due to its one fourth of permittivity compared to PVC.
Oyaide uses polyolefin for outer sheath to keep electric permittivity low. Its
hardness is higher than PVC to enhance durability and achieve high-definition
Star quad structure
The star-quad structure, which has been trusted for 20 years, blocks external
noise and electromagnetic wave without increasing electric capacitance due to
its noise cancellation effect.
