Knowledge of audiovisual electronic wire

 The original author is "Getting Started Audio visual facilities Basics - Video Interface chapter," describes the audio facilities outside the common video interfaces Here follow the editor to continue the "consciousness" about the most common audio interface bar.
It is currently the most common type of the line audio interface (external as indecent and integrated video interface), is often common for the two, transmit stereo sound. That kind wire connection end female late emerging era, being radio rca filling sound from the company invented, so it is called rca interface. rca audio side female pairs normally used to transmit basic stereo audio signals, commonly marked differences in color: red left channel (letter "r" indicates "left" or "Red"); left channel black or white. And it also carries multichannel no other types of colors.
Knowledge of audiovisual electronic wire entry audio-visual equipment basics - audio interface articles, xlr female balanced side
It is a kind of three-wire connection end female, three wires are reverse polarity, negative and shielding. xlr called "balanced side female" and "microphone plug", the normal terms of use are Boye or broadcast television category, but are some of the more top-class home audio installations are also commonly used to being pre-amplifier and the amp's between the signal transmission. xlr side woman advantage is that the equilibrium linear transfer signals that can be transmitted over long distances the audio signal is greatly reduced electrical female workers do the electromagnetic system, radio disturbance and the audio signal is generated outside the noise and hum.
Women's knowledge scale electric wire 1/4 inch (6.35mm) Labyrinth headphone plugs and jacks are designed to come from the early telephone wiring board, and that women are av class terminal equipment properly on a three-line layout (divided into left / left channel of each one and the ground), so the stereo signal output. Also commonly used Boye or broadcasting equipment on, and this was double layout (divided signal and ground) for transmitting mono signal; without also using the three line layout (divided into reverse polarity, negative and shielding) to equalize mono signal is transmitted.
The Labyrinth 1/8 inch (3.5mm) mini headphone end female little personal confidence will not unfamiliar to the bar. Its ongoing effectiveness and scale is the same as the female headphone end, used for portable equipment altar stereo signal HDMI to DVI.
According to spdif (sony-philipsdigitalinterfaceformat, Sony - Philips Digital Interface Format) of the scale, the appearance of women taking the same side analog audio rca wire can also be used to transmit digital audio signals. Female coaxial terminal can be used to transmit stereo (cd format) or multi-channel (Dolby Digital / dts) digital signal, plugs normally conducted with orange red and black label. Although any use rca plug wire can be used to transmit digital audio signals, but better to use specially designed for the digital audio cable to get the best possible transmission effect, that is, the impedance of the plug and socket must labeled 75ω.
bnc interface, features and doing it is to spend and coaxial end women are the same, just add a bayonet design, multi-Bo and broadcasting facilities are, the more stability.
woman toslink fiber end and coaxial rca side scale women are the same, are spdif digital audio format, the data transfer is not current through bumps, but by the light pulse, using a special optical fiber to make the amount of media. From toslink output port, you can see the red light, it is not a laser, it would not harmful to the human eye. Dirt and dust barriers to the transmission of light, so do not touch the connection when using the mouth, they also take Needless dust caps to the port, in addition, fiber optic cable is not excessively bent together can perhaps distorted, otherwise it will form of injury is always used instead of grams less.
Female end of the fiber optic necessary optical and two conversions, a bit lost signs appear, and cd signs outside jitee is constantly let Peng Ming heart engrave bone fever. But unlike copper susceptible to electromagnetic fiber nuisance is no better long-distance transmission can guarantee.
