I want to use the computer, TV box, projector, amplifier, speakers of the big 5 to establish a home theater system, I don't know how to connect between the output terminal, such as high-definition TV box and is connected by the projector or and amplifier or connected to the computer in the access projector? Video output terminal computer is connected directly or through the projector in the power amplifier and the projector connected? All connections are through the amplifier as the center? Thank you for pointing!!!
The problem is very complicated. The complicated reason is that the requirements are different, and the connection modes are different! Here I am from low to high requirements require one said: 1 common VGA (computer graphics, video line) with projection projector, now have a basic VGA port; at the same time the TV box connected with the projection AV cable, head of the yellow line is generally used in DVD; and a two audio line with the sound that is the kind of computer connected line usually active speaker connected on the audio cable TV box; at the same time connected power amplifier, power amplifier and speaker finally. (add here is if the cards have S video S video line with the mouth or, if TV box S port video line do not use a component AV cable, line S line (don't you want to see what instructions have connection and export); the above refers to the music class work on double track, not what 5.1, 7.1 multichannel AV amplifier 2) if your projector is good enough, such as enough 1080I or 1080P HD projector I suggest you buy a HDMI interface card, and now hundreds of yuan. The computer then uses HDMI to connect the projection; the HDTV box uses the S port or the component line to connect the projection;
Now another problem is your power amplifier: three cases, one, music power amplifier, connection method said before. Two, AV multi-channel power amplifier with digital optical interface, you'd better get to pick the sound card with optical output power amplifier, of course, if the card with multi channel output of the power amplifier (also is the sound behind the kind of sound card left right center etc. respectively output). Three, with the HDMI input and HDMI video output AV power amplifier, the power amplifier is relatively high, the computer can HDMI line amplifier, TV box with S or HDMI or component line connecting a power amplifier, the power amplifier with HDMI connected to the projector. Power amplifier to connect the speakers, like nonsense. It's centered on power amplifier, but it's a lot of investment! Look at you ~ ~ ~!Does your power amplifier support HDMI input? And what kind of video card do you have? Some graphics cards integrate 5.1 audio modules, and some do not! Also, your notebook, if there is an optical fiber interface, it solved all the ~HDMI, connected to the projection, the optical fiber connection power amplifier is over! No fiber and then see if there is a "digital 'coaxial interface can be connected with an amplifier 5.1 channel, no external sound card can only buy USB ~ ~ ~ as many of the market innovation X-Fi external sound card more than and 400 ~ ~ OK ~ ~ this is what audio interface.
