Conductor
The conductor of L/i 50 series is made of highly-pure OFC. It is processed by long time annealing process in low temperature for stress removal. Therefore, the internal composition of the conductor is equalized and it actualizes stable electric transmission.

Insulator
For the insulation material of L/i 50 V4, we employed reinforced silicon rubber which has excellent vibration damping property and mechanical strength. It absorbs vibration generated by instant current addition changing.

Star-quad structure
The star-quad structure is employed for L/i 50 series. Due to the fact that stranded wires counteract to cancel magnetic field each other, the star-quad cable attenuate noise internally compared to regular cable.
Each wire is covered by reinforced fiber sleeve in order to deaden resonance between wires.

Plug / Connector
We employed our original, P/C-029, for the connectors of L/i 50 V4.
The contact of P/C-029 is made of brass which provides natural and wide range sound image. The body is made of highly rigid 30% glass filled PBT that actualizes high-speed vibration attenuation.
