COPPER LEAD DRAIN WIRE: Drain wires are used in cables in conjunction with a metallic shield to ensure effective grounding. The drain wire serves to complete an electrical circuit from the shield and carry unwanted electrical noise to ground away from the circuit providing superior noise reduction

100% OXYGEN FREE COPPER WIRE: OFC wiring is manufactured using a process that minimizes the presence of impurities, specifically oxygen. By removing oxygen from the copper, OFC wiring reduces the risk of signal distortion and enhances signal purity, resulting in cleaner and more accurate audio reproduction.

LOW SIGNAL LOSS: OFC has a high electrical conductivity, which means it offers low resistance to the flow of electrical signals. This property reduces signal loss and ensures that the audio signal is transmitted with minimal degradation over long distances. It helps in preserving the original audio quality and maintaining clarity.

OXYGEN FREE COPPER CORE AUDIO CABLE: OFC cores have excellent conductivity, allowing for efficient transmission of audio signals. Additionally, the absence of oxygen in OFC reduces the likelihood of oxidation and corrosion, which can degrade the signal quality. By minimizing resistance and maintaining a clean signal path, OFC cores help mitigate the effects of EMI and RFI.
