RCA connectors are cheap in production, easy to install and can be used in many different applications. RCA connector allows to transfer video and audio signal as well as digital S/PDIF signals, however, the maximum distance is limited due to its susceptibility to electromagnetic interference. This problem can be partially resolved by using shielded cables and individual cables for each signal. |
