The SV900 is designd for balanced digital signal transmission. It greatly reduce harshness in high-frequency signal transfer and creats a deep ,smooth and dynamic performance. The XLR type connectors are recommend with the SV900. It utilizes OCC as the conductor , twisted pair in triple insulations with high density PE and conductivity PVC, and tight oxygen free copper braid for 100% protection from high-frequency microwave and EMI signal corruption.
