An RCA converter is a device that is intended to run a conversion signal from something that is designed to run on a three cable RCA system to a television that has only been set up to receive signals through a coaxial cable. Chances are that this is something that you might need if you are trying to use a newer model DVD player with an older television set that does not come equipped with the proper output jacks that are needed to run the device. This could also be something that you might need to use for cable and satellite boxes.
If you are unclear as to whether or not the RCA converter is something that you may need with your entertainment system, you only need to check on the back of the television set to find out. If there is not a three cable jack system on the television, but there is a small silver jack that can be directly linked up to a cable line, then you will probably need to buy the converter. There are some converters on the market which can change it to where you can easily plug in the RCA cables to the coaxial cable hook up, but sometimes these do not work that well.
One of the reasons that you might require a more advanced RCA converter is that the signal will remain the same if all that it is doing is modifying the plug to where the cables can be properly hooked up. If you want to make sure that the picture you are getting on the television set is the best one possible, then you will want to make sure that the converter you are using is one that will be able to completely alter the signal that is going through the RCA cables and into the coaxial output node so that it can be properly deciphered by the television. This kind of RCA converter is known as an RF modulator.
However, it might be possible for you to hook up the equipment without having to use an RCA converter at all. For example, you might be able to use a newer model VCR to achieve this transition. This is because the later models of VCRs have both RCA cable outputs as well as coaxial cable outputs. So, you can hook the television set up to the VCR and then you will want to connect the other device (i.e. cable box, DVD player) to the VCR as well. The VCR will then act as a converter for your signal and you can see the picture clearly on the television set once the VCR has been tuned to the proper channel. You will also need to make sure that your television is able to access the video channel in order to view the picture correctly.
With the reduction in the number of VCRs that are available on the market, you will probably want to go ahead get a traditional RCA converter. Not to mention the fact that the converter itself is probably a lot less bulky than using a VCR, so you will have more room around your entertainment center, and this can be greatly beneficial. The good news is that RCA converters are readily available on the market from a number of stores that deal in technology equipment so you do not have to go searching for them as you might have to if you are trying to find a later model VCR that fits your needs so that it can work as a converter.
