Disadvantages of RCA cables
The only problem with RCA cables is that each signal requires its own plug. Even in the case of attaching a cassette deck may need four of them, two for stereo input and two for stereo output. In any setup, this may lead to a mess of cables, which is gone worse if one considers more complex signals like component video.
There have been many attempts to introduce combined audio/video connectors for direct signals, but in the analog world none of these have become universal. The 5-pin DIN connector was however, popular for bi-directional stereo connection between A/V equipment, but it has been entirely displaced on modern consumer devices. Nearly all modern TV sets, VCRs, and DVD players have SCART connectors, though sometimes supplemented by RCA and RF connectors and besides these, there are also SCART-RCA adapters.
Separate RCA connectors are conventionally used, supplemented by RF connectors for backward compatibility and simplicity. Even though mini-DIN connectors are sometimes used for S-Video connections, composite video, component video, and analog audio (mono or stereo), all use RCA cables unless RF is used. In the digital world, however, combined A/V connectors are gaining ground, while HDMI is commonly being used in the modern times.
For the audio signals, an RCA cable is called unbalanced, and a true balanced connection is generally preferred in certain applications as the RCA cables allow for the use of long cables while reducing the susceptibility to external noise.
