Despite the introduction of more advanced audio and video signal cables such as HDMI and Toslink most audio and a large number of video connections still use the common RCA connector. This is a premium two-channel audio cable made of RG-59 75 ohm coaxial cable. The cable uses a 22AWG conductor and is shielded to prevent EMI or RFI interference from entering your audio system. The connectors are gold plated for smooth connections and to prevent corrosion. Each connector head features embedded color-coded rubber rings to ensure a firm grip when installing or removing the cable.
