Early surround systems (Dolby surround and Dolby Pro-Logic) could be transferred between components by the same RCA cables that carried the left and right audio signal but with the advent of digital 5.1 channel surround came the need for a more complex system of signal transfer. The following are the different ways that the surround signal is transferred between components.
Generally, there is a digital signal source such as a DVD player, DAD player or laser disc player. Some of these players have a built in decoder and will have analog 5.1 channel outputs. If there's no built in decoder, the digital source will offer a fiber optic and/or a coaxial digital output.
5.1 Channel via RCA Cables:
This type of signal transfer is the most low tech but requires more cables to transfer the 6 channels of audio. It simply uses 6 RCA type cables/connectors. This type of connection is generally used to transfer the signal from a component with a 5.1 channel (Dolby Digital or DTS) surround sound decoder to a receiver, preamp or multi-channel amplifer.
As a refresher, the 5.1 channels are:
Left (rear) surround
Right (rear) surround
Digital Signal Transfer:
The raw digital data can be transferred from a DVD player or other digital source via 2 different single cable connectors. They are the optical and the coaxial cables.
This type of cable uses a connector like a common RCA cable but the insulator of the cable itself has much lower capacitance than a common RCA cable. The lower capacitance cable is needed due to the higher frequencies of the digital signal (compared to audio). This type of cable is probably a little more durable than a fiber optic cable but may cause a hum to be induced into the audio. This hum would be a ground loop and would likely only be a problem if several other pieces of audio were connected in the system.
This type of connector uses a fiber optic cable to transfer data between components. It is probably less robust than the coaxial cable but is not going to cause any ground loops because there is no ground connection involved.
This site was started for pages/information that didn't fit well on my other sites. It includes topics from backing up computer files to small engine repair to 3D graphics software to basic information on diabetes.
This site introduces you to macro photography. Macro photography is nothing more than the photography of small objects. It can take quite a while to understand the limitations associated with this type of photography. Without help, people will struggle to get good images. Understanding what's possible and what's not possible makes the task much easier. If you need to photograph relatively small objects (6" in height/width down to a few thousandths of an inch), this site will help.
If you're interested in air rifles, this site will introduce you to the types of rifles available and many of the things you'll need to know to shoot accurately. It also touches on field target competition. There are links to some of the better sites and forums as well as a collection of interactive demos.
This site helps anyone new to computers and anyone with a basic understanding of computers with a desire to learn more about the internal components of a computer. If you have a computer that you'd like to upgrade but don't know where to start, this is a good site for you.
