Electrolytic Touch Pitch (ETP) High Conductivity Copper Audio Cables are used for microphones, studio interconnects, receivers, power amplifiers, speakers, etc and are also used for the internal wiring of high end speakers themselves.
Ruggedized, deployable microphone for studio or live performance; Balanced analog audio XX'foot Belden 8424 20/4C Star Quad Shielded Low Impedance Microphone/Audio/Instrumentation Cable. It has x4 20awg EPDM (Ethylene Propylene Diene Monomer rubber)-insulated color-coded fine stranded (26x34 stranding) high-conductivity tinned copper conductors, spiraled together, then covered with a rayon inner braid to maintain conductor orientation, then wrapped in an 85% coverage tinned copper braid shield, then covered in a cotton separator wrap, lastly all wrapped in a black EPDM jacket. Rated 60C/600V. Made in the USA. See specs below.Quad connection scheme: The black and red wires (or wires directly opposite one another) are connected together to form one conductor, and similarly the white and green wires (or remaining wires) are connected together to form the second conductor. High Conductivity Copper is Belden's version of the oxygen-free copper (OFC) that is touted by some other manufacturers in their audio cables. Electrolytic Touch Pitch (ETP) High Conductivity Copper Audio Cables are used for microphones, studio interconnects, receivers, power amplifiers, speakers, etc and are also used for the internal wiring of high end speakers themselves. Premium Belden audio cables utilize only high-conductivity copper produced by a process called Electrolytic Tough Pitch. This refining process produces a conductor that is pure copper, resulting in high-conductivity per ASTM B115. The high purity obtained from ETP copper results in superior audio cable performance.
