Any system setup requires the use of audio and video cables. From various types of video connectors to setup questions, the process of getting the right connection without having more than you need can be confusing. Here we will briefly describe the various types of cable and answer a few frequently asked questions.

There are seven basic types of cables. RCA Composite Video is standard on a variety of newer devices and offers good quality picture. S-Video and RCA Component Video are preferred to RCA Composite Video and offer higher quality transmission. BNC Component is similar to RCA Component but locks into the device while RCA merely plugs in. BNC is preferred to both S-Video and RCA because of the more secure connection. VGA offers high quality analog video transmission and is standard on PCs, monitors, and video projectors. DVI is used for digital transmission of extremely high speed uncompressed signals. DVI is another option to use whenever possible because of the benefit of uncompressed transfer of HD video. And finally, there is HDMI. Unlike DVI, HDMI sends both audio and video signals simultaneously and adjusts automatically to the most efficient route. However, it has the added bonus of being compatible with DVI in many cases. HDMI is a highly recommended output option.

After choosing the type of cable you need, the next question is often length. While you don't want a cable that is too short, extra length can distort the signal. You'll want to measure the distance between the two devices you'll be connecting. The best way to do this is by using a string to assimilate the connection. Once you run the string from point to point, measure this to determine the cable length you'll need. From here, it's best to round up to the nearest cable length. Too short of a cord can be difficult and awkward to connect. Too long makes it hard to manage and in some cases can reduce the signal quality. However, a little extra length eases the process and can keep things neat.

The two main types of audio cable are digital and analog. Digital offers the best sound quality and is the preferred transmission method. The problem is that many devices aren't wired for a digital connection. That's where analog connectors come into play. While the quality of analog is lower than digital, it still offers a great signal. RCA is the standard connection on most audio components.

What about combo cables? A combo cable, or that carrying the audio and video signal in one cord, is recommended for A/V devices such as a VCR or DVD player. Both audio and video signal on a single cable offers a tidy and low cost connection. However, audio-only devices should only use an audio cable, as suggested by the name.

Overall, the type of cable you use largely depends on the device and your specific needs. Often your owner's manual can tell you exactly which connection you need. These tips will hopefully help to guide you in the right direction as well. Good luck and happy connecting!
