Recta 是HARMONIC TECH使用方芯導體的發燒級線材系列。由於大部分信號只走在導體的表面，造成導體的中心部分子傳送極少量信號，當導體的直徑越大，行走在表面的訊號和中心的信號量的差距就愈大，產生了所謂的集膚效應。方芯導體的出現，由於其物理結構沒有了中心點，所以可以把大部分的信號在表面上傳送，防止了集膚效應的出現。導體的表面由電容值較低的特氟龍物料絕緣, 有助信號流暢地傳送.
Description:
Recta is a high-end cable series from HARMONIC TECH that utilizes flat-core conductors. Since most signals travel along the surface of the conductor, the central part transmits very little signal. As the diameter of the conductor increases, the disparity between the surface signal and the center signal becomes larger, leading to the phenomenon known as the skin effect.
