Wiring
Miscellaneous
The best Wiring is no Wiring. As the single units have to be connected to each other, in practice, it is recommended to keep the cables as short as possible and to keep the sound interference as low as possible. Furthermore, you need to check if the cables all have to run in the same direction.
The following contains cables and sockets that you will more than likely come into contact with in the setting up of your HomeCinema system.
Video cable
Composite / FBAS cable
RGB cable
S-VHS / S video cable
VGA cable
YUV (component) cable
DVI cable
Composite / FBAS cable
The FBAS cable - also called composite cable - has managed to achieve recognition in the amateur field for transmitting video signals with low conduction from one device to another. Here, all of the color and brightness information is transmitted by wire which means that one must accept losses in contrast, as a result.
RGB cable
The RGB cable, that is known as the highest quality video connection, transmits signals for the three basic colors (red, green, blue), and the horizontal and the vertical deflection in separate cables which means that the color resolution is definitely more sharply focused. At the moment in Europe, this signal is mostly transmitted via SCART cable although the RGB signal from the SCART socket is not compatible with the RGB port of the projector.
S-VHS / S video cable
... also called Y/C cable. It transmits black/white ( Y ) and color signals ( C ) separately and is essential as a minimum requirement to transmit a DVD picture. The S video cable is composed of four internal wires. The name "S video" came about because of the video recorders and the introduction of the S-VHS standards. The high quality Y/C connection, the so called "4 Pin Mini Din plug" was specially developed for this purpose.
VGA cable
This is mostly used in connection with computers to transmit a progressive RGBHV signal. In addition, it is also used for PAL progressive scan DVD player.
YUV cable
The YUV cable has its own wire for every signal. The connection is usually made via three cinch jacks. Y represents the black/white signals, the color part (UV) being transmitted via the other two cables. It is known as a good connection for projectors but is not used with television. It is used for HDTV transmissions.
DVI cable
DVI (Digital Visual Interface) is a very high quality picture-transmission standard developed by the American manufacturer Silicon Image. Especially the sensitive signals of the HDTV (High Definition TV) are only able to be lossless transmitted by DVI. The DVI cable, especially developed for this task, is again defined under DVI-D (only for digital signals) and DVI-I (for digital and analog signals).
SCART cable
The SCART cable offers the most complex connection between a video recorder and respectively, a DVD player to an A/V receiver and an audio component, partly but also directly to a projector. You can see the effects by the extensive replay and passing possibilities for pictures and sound. The following can be transmitted as video: S video (S-VHS video), composite (FBAS) and RGB. The audio signal is transmitted as stereo sound over two NF wires. High quality SCART cable can clearly optimize the quality of your HomeCinema system due to the many transmission variants. Be careful that all of the 21 poles are connected before you purchase your SCART cable.
Audio cables
5.1 DVD audio cable
Cinch cable
Light-wave power cable
Phono cable
Symmetrical / unsymmetrical cable
Subwoofer cable
5.1 Cable
… also called 5.1 DVD audio cable - it is an NF cable for transmission of analog signals. They are, for example, used for the replay from DVD audio sources in contrast to DVD video where a digital data stream is issued. These cables are made up of six NF audio wires. The spectrum of frequencies of DVD audio, in comparison with usual CD's, is far broader. For optimal sound pleasure, it ensures a perfect signal transmission through its high quality Wiring.
Cinch cable
… also called stereo NF cinch cable - transfers the sound signals from, for example, CD player to amplifier. Through its analog transmission form, it is liable to interference, though. That's the reason for high quality cinch cables not only having a high purity internal wire conductor but also an extensive shielding.
Light-wave power cable
The light-wave power cable is a glass fibre cable. It transmits information in the form of light impulses. In comparison to copper Wiring, the light-wave Wiring isn't sensitive to external interference ( e.g. electromagnetic fields ), so that it is not in need of any shields. Due to the high data rate, signals with a very wide band can be transmitted over long stretches loss-free. Light-wave power cables are used in the entertainment electronics to transmit digital audio signals. The plug on a light-wave power cable is called a Toslink plug.
Phono cable
Here we are dealing with an optimal (NF) audio cable especially for the transfer of analog signals from the record player to the amplifier.
Symmetrical / unsymmetrical cable
In comparison to the unsymmetrical cable that has only a neutral wire and shielding, the symmetrical cable has two internal wires with different polarities which mean that it is resistant to interference.
Subwoofer cable
The sub-woofer cable (NF cinch cable) is optimized especially for deep frequencies till 100 Hz so that the bass output of a sub-woofer is increased considerably.
