HQ Ultra cables feature high conductivity, low electric resistance, and excellent signal transmission. They feature OCC oxygen-free copper, which is the most proven conductor currently available for high fidelity audio and video systems. The foamed PE insulation offers a true 75-ohm impedance that transmits image signals with the highest stability and fidelity. Triple shield foil minimizes circuit interference and obtains a high signal-to-noise ratio. Each cable has premium locking RCA connectors. You can count on this design to provide a secure connection in any system.
