<br> <BR> Today, many people play on a home theater, there are a lot of people will join the ranks. .A lot of audio-visual equipment will be moved back home, you may be more to consider is how to connect these devices, which involves a problem. .More audio-visual equipment, wire, and sometimes may face long-distance connection (such as the study of computer-controlled living room TV screen), and many of the colored wires exposed if all, not only affects the appearance, nor safe, therefore, wiring every .a home theater an important step in the player can not be ignored. .<BR> Do not hear the wiring to dizziness, in fact, just take a little time to find out, rookie can complete the wiring in your home work. .So, what, when routing? .Fabric which lines? .How to wiring? .You do not worry, follow our tutorial, you will be able to a preliminary understanding of this knowledge. .<BR> Before entering the subject, let's look at the classification of wire. .According to the different connected devices and uses, we will be divided into home theater cable video cable, audio cable and speaker wire three categories. .Video line is used to transmit video signals, connect a TV, projector, computer, etc.; audio line responsible for the transmission of audio signals, the main connecting audio equipment and amplifiers; speaker line suggests that it is connected with the speaker amplifier. .In particular, in recent years there's HDMI cable can transmit video and audio signals, to facilitate the connection, the signal is good, is becoming the mainstream audio-visual equipment, connections, audio-visual equipment in recent years, most of the market with HDMI Interface .. .<BR> Understand the classification of wire to wire to take a look at the mainstream. .<BR> Line is mainly used to connect the video playback device and display device. .Play equipment usually includes DVD, HTPC, etc., the display device is currently still the main TV, in recent years have gradually been recognized projection, home theater with a projector set up more and more. .Let the mainstream video cable to make a simple introduction: <BR> AV cable: is the oldest video transfer analog video signal cable, both ends of the RCA (RCA head), the current DVD and TV have this interface, .Such lines do not need to fabric decoration; <BR> <BR> S Cable: AV line quality better than the video line, the interface is circular, because of its weak anti-interference ability, the use of no longer than 7 meters. .The current line is relatively backward, does not recommend cloth; <BR> <BR> Y / Pb / Pr component cable: S terminal wire line quality than the better video cable, analog signal transmission, the current analog signal should be the most .good video cable, if you use high-quality wire and connectors, even with 10 meters of cable are able to transmit high-quality screen. .When your playback device and display device further away, then, be considered when fitting cloth color line. .<BR> <BR> VGA cable: the D-Sub. .Is also an analog signal video line is the common interface types on the computer, the signal compared with the component cable is different, but with the increasing amount of video data, such as video signals to be transmitted 1920X1080P, then the color line redundancy .I will be even greater, the resolution after more than 1600X1200, VGA cable lesser quality, slightly longer lead to snow, it is recommended cable length should not exceed 10 meters. .In recent years, the family gradually into the projector, the projector comes with all the VGA port, therefore, necessary to consider when wiring the wire. .<BR> <BR> DVI Line: The VGA is the most common computer interface, and the difference is that VGA, DVI can transmit digital signals, no need to carry several analog conversion, so the picture quality is very high. .Currently, many high-definition television also provides a DVI interface. .Note that, DVI interface, a variety of specifications, common is the DVI-D (Digital) and DVI-I (Intergrated). .DVI-D can only transmit digital signals, we can use it to connect the video card and flat-panel TV. .DVI-I can be in and VGA DVI-D conversion. .In general HTPC graphics card is DVI-I interface, the general, and LCD monitors, projectors are DVI-D interfaces, DVI-I to DVI-D interface, although the interface is compatible, but the DVI-I plug is DVI-D plug can not .interface, however, turn with a DVI-I DVI-D converter can be resolved. .<BR> <BR> HDMI cable: the latest digital video cable to transmit uncompressed all-digital signal technology, the maximum transmission speed is 3.95Gbps, HDMI in addition to transmit video, also supports eight channels of 96kHz or 192kHz mono .digital audio transmission, and its interface with the DVI interface converter (audio signal loss.) .If you use high-quality HDMI cable, even if the length of more than 20 meters can still get excellent picture quality. .<BR> Audio line is used to connect audio equipment and power amplifier. .<BR> <BR> Better sound quality on the market line, the production of materials include gold, silver, copper element oxygen, high carbon non-metallic line to import more, but its price is more expensive, both in general .to be a few hundred dollars, mainly in the United States MONSTERSTANDRDINTERLINK (Monster), AUDIO0UEST (Line St.), SUPRA (shark), M0NITERPC (magic), SPACE & TIME (Macross), MISSION (vocal), PATRDNICS (Mitch .), BELKIN (Belkin), the Netherlands, VDH (Fan Denghao), Germany's LUXON (Vivitek), YARBO (Ya Fort), Japan's Furukawa, domestic Akihabara, Po Wan, and also produced the opening of high-definition player .Bor, top tripod, love as of other brands. .<BR> <BR> Million less for the universal audio cable wires do not have to deliberately pursue high quality, as long as the greater use of general cross-section of copper signal cable. .For more high-end home theater audio equipment, consider using high-quality audio cable, high-quality speaker wire for improved sound can get a more significant role. .Always follow the wire with a purpose: as far as possible to the true balance of equipment, the best natural acoustics. .<BR> Audio cable: a audio cable is usually two, is divided into left and right channels, the line ends are RCA (RCA head). .<BR> Coaxial line: for the transmission of multi-channel signals (Dolby AC-3 or DTS signal), and audio line similar to the signal due to large amount of cable joints and thicker than an ordinary audio cable. .Coaxial line suitable for music. .<BR> Fiber-optic lines: also for the transmission of multi-channel signals. .Since the signal transmission process to go through two transmitter and the receiver conversion, the signal is slightly distorted, however, is still very suitable for watching movies. .Fiber-optic lines commonly used plastic materials, quartz and glass, including glass fiber line performance the best, but expensive. .<BR> <BR> Microphone line: a two-core coaxial cable for connecting amplifier and microphone. .The rise of wireless microphones, if not for special consideration, the wiring can not be considered, after the wireless microphone will certainly be more widely applied. .<BR> <BR> Audio cable in the wiring when the basic need to consider, because the audio equipment and amplifiers are often together, these lines are very short, post-configuration can be. .<BR> Speaker cable for connecting the amplifier and speakers, which is much larger than the previous flow of said current signal and audio cable video cable, because the signal amplitude is large, these lines often do not have the shield for this cable, the key .is to reduce the resistance, because modern power amplifier output resistance is very low, so the speaker wire requirements also will be increased, such as a large selection of cross-sectional area or stranded wire. .<BR> <BR> Copper wire to the silver lines are from the more expensive price of a speaker for the oxygen-free copper speaker wire dedicated line, the main characteristics of good conductivity, low resistivity, used it in heavy .put a lot of sound sound increased. .<BR> <BR> Home speakers according to the classification, divided into home theater speaker (generally six) and HIFI music speakers (two), generally known as fever speakers. .<BR> <BR> HIFI speakers for high-fidelity audio sound field reduction, so the lossless transmission of audio signals have sufficient protection. .General transmission line signals on different frequencies have different impedance, which features on the reduction of the sound performance of the sound vague, for it produced a high-end line known as the Intelligent Signal speaker cable, the characteristics of this line .According to the level of the signal frequency is divided into two channels, a certain thickness of the outer layer above the signal line through 5KHZ, 5KHZ following signals transmitted through the inner line, which greatly improved the frequency characteristics of transmission lines, so that playback .clear and transparent sound. .But the price also very expensive, as those mentioned above, the audio cable brand, but also most of the production of fever speaker wire. .<BR> <BR> HIFI speaker line due to their cost, but also two speakers, the proposed renovation without wiring, you can take the open air, so you can upgrade at any time and deal with second-hand products. .Home theater speaker cable wiring when the focus of the decoration, because the number of multi-speaker, will take the open wire clutter. .<BR> <BR> Home theater speaker for playing movies, the film's main purpose is to reproduce surround sound effects, gives rise to the immersive feeling, because its rich multi-channel sound signals, the human ear is no longer capacity .to understand the details, so home theater speaker wire can not be overly demanding, the general cores with copper to 200, usually a few hundred yuan in the 50 meters. .<BR> <BR> Here also emphasize the bass home theater speakers, this speaker is generally active speakers (and amplifier and speaker combined in one), which is the root weak signal speaker cables audio cable, usually in the purchase of speakers .distribution when the manufacturers have had a very long line of active subwoofer, if still not long enough, you can use relatively thick core coaxial signal line. .<BR> Said wiring, the first time is very important. .Is best to choose the new home renovation and decoration have not yet carried out simultaneously, when wiring more convenient, and, decoration does not appear to be destroyed when finished and then wiring the walls and the ground pretty embarrassing. .<BR> <BR> However, there are a lot of friends did not buy a house when considering the purchase of home theater, and have no place left for the route; and some friends use the TV as a display device, and want to install to create a home theater projector ., also encountered a wiring problem. .<BR> <BR> First of all, the wiring for the simultaneous fitting, if only using the TV as the display device, you can not have too many issues to consider wiring, if you want fully compatible with regular TV, LCD and plasma, projector and other equipment, first planted .Most devices support the VGA cable. .Also laid the best component cable analog signals, digital signals and HDMI cable DVI cable. .<BR> <BR> The audio line is used to connect audio equipment and power amplifier, because the two are often placed together, wire short, post-configuration can be. .With the rise of the wireless microphone, if not for special reasons, may not be considered when wiring the microphone line. .<BR> <BR> Speaker wire because of the large number should be the focus of pre-wiring. .<BR> Has been renovated for good friends, of course, you can choose the floor and the wall on the way cabling slotted holes. .If you do not want to bother, you can choose a similar style and decoration to hide the wire trough. .The trough should choose the ground voltage wiring, security, good products, so as not to cause inconvenience to the daily walk; and wall-to trough than focus on safety performance, but also take into account their decorative properties. .<BR> <BR> In fact, in many cases, we have seen some very interesting friends in life, a variety of small ornaments to hide the wire, for example, the projector outside the winding wire of a flower vine, etc. .. .If more than brains, you will find, in fact, cleverly hidden wire is not difficult. .<BR> As more and more friends using the projector, we highlight the wiring method of projection. .Connect one end of the projector's video cable or HTPC such as DVD playback device, the other end connected with the projector. .DVD is generally fixed position, usually in the middle of the front of auditorium, the location of the projector there are three: <BR> <BR> 1. Using the hanger to hang the projector back in the auditorium or the living room ceiling ., the position of the upper and lower adjustable, more flexible; <BR> 2. the projector placed on the back of the auditorium or living room cabinets; <BR> 3. will be portable projector on the projection of the car, placed in the human .front. .<BR> <BR> Either way, have suggested that the video cable from the ground or the ceiling from front to the rear of the Central Office is connected to a suitable location because the two video lines: component cable and the DVI cable is very thick, exposed .the outside is difficult to see. .<BR> <BR> Component cable and the DVI cable is too thick, are not wear tube, only with trunking, floors, wall to consider its height. .<BR> <BR> Component cable and DVI cable do not have the appropriate jack on the junction box mounted on the wall after, leaving a length of one meter for direct connection to DVD or projector. .No suitable panel can use the whiteboard, so that the decoration can be a hole in the above workers. .<BR> For the average home theater and smaller theater, you can choose 5.1, if you require a higher sound quality and room size is large enough, you can consider installing a 7.1 channel system. .<BR> <BR> <BR> <BR> Connect one end amplifier speaker wire, one end to connect to speakers, 5.1 channel connection scheme as shown below, low bass speaker because no direction, generally placed near the PA, not .dark line to be cloth. .<BR> 5.1 multi-channel speaker placement and wiring diagram <BR> <BR> copper core if using 200 words, the speaker wire can wear the PVC tube, junction box at the bottom of the wall marked the location box, using panel .whiteboard will be a (or the holes can be on the board), the speaker wire out of the wall to leave after more than a meter long, for direct connection amplifier and speakers. .<BR> <BR> Height of the front main speakers should be seated ear height with the same surround speakers higher than the human ear can be about 60-90 cm. .<BR> <BR> Understand the basics of wiring is not enough, and placed with audio and video equipment, but a science, requires a little thought to the mystery. .This tutorial limited space, only a limited amount of information, on the home theater should be more interested in looking for information on friends and see Oh! .<BR> <BR> <BR> <BR>.
