The signal line of audio equipment is mainly used for transmission of high-frequency currents, whereas the power cord is for transmission of low frequency currents. The conductor manufacturing substances would affect both.

BTL wires deploy different series of gold, silver and copper material for better regeneration effects and superior high fidelity. A correct proportion and combination of substances helps the transmission signal specifically and makes for effective targeted deployment.

Each wire in the design is based on precise calculations, total length and exact material combinations which need each other to integrate into the required appropriate ratio, and subject to extremely high temperature treatment thereafter. Before being sent out of the factory, the products are tested to ensure they are the best quality based on the industry's best current standards.
