Why are RCA Cables Necessary in The Wireless Age?

1. Why are RCA Cables Necessary in  The Wireless Age?    Wireless headphones, wireless chargers, wireless speakers and               a whole bunch of other wireless things are here to stay now.                         ‘Cutting the cord’ is the trend.    However, certain products are simply not there yet.    1​​

2. If we talk about televisions, even modern day ones that                     literally roll out of sight, they have to use cables for power, for                           additional I/O needs, etc.    The new age televisions that roll out of sight, or stick to walls                           like posters, still have to have some way of connecting other                       devices to them. So, we are nowhere near getting rid of cables                         altogether yet. The cables themselves have evolved over the                   years. There are of course cables that are simply audio, like the                         much controversial 3.5 mm headphone cable. Then there are                   also solutions for managing both the audio and video,                   together.      2​

3.   So, if we have come this far, why do televisions still have the                           dated red, yellow and white ports? What is the use of them?    Well, those are RCA ports, to which ​RCA cables connect for audio and video. The yellow connector at the end of the cable                                               is for composite video, the red one, for the right audio                       channel, and lastly the white one for the left audio channel of                         stereo sound.    3​

4. The main purpose of these audio video cables in terms of a                         traditional television set is to connect a video input device,                     making the TV itself the audio output device. So if you were to                           connect a video game console to a standard TV, the console                       would be the input for the video, the TV would display it, and                           the TV speakers would provide the sound.    But this is the most basic setup, and standard RCA audio video                         cables are not as updated as one may need them to be. They                           cannot provide the display in extremely high resolution, which                   we have come to expect nowadays. ​RCA audio cables are, however, the analog solution you need if your display lacks the                                           fancy multi-channel HDMI port. You will always find RCA                   ports saving the day.    RCA cables cannot combine multi-channel audio in one cable.                   Therefore, there is one cable for each channel you may want                       to add to your set up, including a certain number of                       subwoofers if that’s your requirement. Anything over four                 channels and a subwoofer might be too overwhelming for a                     home setup. However, audio feedback largely depends on the                   4​

The things that you need to                       connect to a display have increased over time. You probably                     have a satellite DTH box, a gaming console, a DVD player, a                         variety of speakers, and lastly a streaming box or stick. When                       all put together, it requires a minimum of two HDMI ports, a                         5​

And here’s how you can                       do it:  ● The main element of a home theatre setup isn’t just a                       large screen. Proper surround sound is an essential part                   of the whole experience. You can add multiple speakers,                   via RCA cables, connect an array of subwoofers and                   enhance the sound.  ● Adding speakers to a display also has another advantage.                   If one speaker were to malfunction, you can simply                   replace that particular channel without having to replace                 your whole setup. This increases the longevity of a very                     expensive home theatre system.    “RCA Cables were first seen in the 1940s which were introduced by ​Radio Corporation of America​. They didn’t have the idea that their product would last till date.”                                          6​

7. They might not be the best but they do the work.    And in case you were wondering how to connect the RCA                       cables to HDMI or vice versa, then we have covered that in the                           next section.    HDMI is used for digital signal whereas RCA cables are for                       analog signaling. To convert the RCA signal to HDMI or vice                       versa, there needs to be an active signal converter.    How to convert or connect HDMI to RCA?  ● You can find HDMI cable with RCA connectors on the                     other end. These look pretty and seems like a perfect                     solution for a complicated problem, but these cables don’t                   work at all.  7​

8. ● There are companies selling HDMI to RCA converters                 which will do the work you want them to but only if the                           HDMI signal isn’t encrypted.  ● Then you can also go with HDMI to RCA converters which                       come with built-in decryption. With these, the problem of                   HDMI signal encryption goes out of the question.  This article is Originally Posted here; ​Why are RCA Cables Necessary in The Wireless Age?                        If you found this article useful, here are some others that                       may be of interest.    Types and Uses of VGA Cables  Why is an audio flat cable are better than the regular ones?  Tips For Selecting a Right Hospital Grade Power Cord        8​
