How Wireless Speakers Work.
Sometimes, though, it can cause humming over your speakers and even potentially damage your equipment. Skip to content. If you do not switch it on, you will not be able to hear any sound.
Quizzes " " Organ Function Quiz. Like the Supremes, these plugs come in groups of three -- typically red, white and yellow -- each consisting of a signal-carrying pin encircled by a ground ring [source: The result is the cleanest form of signal transfer currently available. Fiber optic audio cables, as the name suggests, use fiber optics to transmit sound.
Ground loops are, from an electrical engineering standpoint, a fairly complex subject. Join 250,000 subscribers and get a daily digest of news, geek trivia, and our feature articles. An optical audio cable can be more prone to problems than a coaxial cable so you have to treat it carefully.
A fiber optic cable is simply several small strands of polished plastic specifically designed to transfer light. Fiber optic audio cables come with caps on the connectors to protect them.
This could be something as simple as connecting to an 'out' connection instead of an 'in' connection.
Fiber optic audio cables come with a variety of connectors, square shaped ones being the most popular. So, as companies dream up better audio and video standards and storage media, they also add new ways to send it crisply from your gear to your ear, which is why the backs of our entertainment systems resemble a 1960s Manhattan switchboard.
It's simply another interval in the evolution of audio, as progressive as Thelonious Monk's compositions. Once upon a time, TVs and stereos were just heavy pieces of wooden furniture.

The name might be an oxymoron, like the jazz waltz "Ugly Beauty," but there's nothing off-key about transposing electrical signals to light waves to deliver powerful, high-quality sound.
You can pipe the HDMI video from the source say your cable box into your TV, then turn right back around and pipe the optical audio out to your receiver and speaker system. The t ip, r ing and s leeve design, in which three insulated sections of the prong handled left channel, right channel and ground, respectively, was so successful that it is still widely used today [sources: The standard was introduced way back in 1983 by Toshiba, and was originally intended for use with their fledgling Compact Disc players.
Try to straighten the cable and see if the sound is restored. At best, this ground conflict does nothing and you never even notice.
Electrical signals degrade over long distances, and are prone to interference from other electrical devices—even when shielded, as with coaxial cable. The other primary type of digital audio connection is the optical connection.
It's an apt comparison, considering that the first analog audio jack, the triple contact plug, or TRS connector , was adapted from the jack first used in telephone exchanges.
