China Home Theater Network (): HD video resources have become popular, HD home theater equipment is also increasingly entering theater homes, large-screen LCD TVs have gradually become popular, so when building new homes, everyone should Considering the problem of home theater audio cabling, even if you don't have HD for the time being, you should lay out the relevant lines in advance to avoid the embarrassment of re-route in the future.
First, the TV connection:
Connected to the TV should be equipped with high-definition cable (HDMI) and at least two sets of audio and video cable (connecting DVD and set-top box and other equipment), or you can reserve VGA cable to facilitate connection to ordinary computers.
The easiest way is to pre-bury a 5 cm diameter PVC pipe between the TV and the TV cabinet. All the wires can pass through from the inside. Because of the short distance, it is very convenient to directly pull out the wire and increase it.
Second, the projector connection:
The price of the projector is lower year by year, 1080P has been within 10,000 yuan; even if it is about 5,000 yuan, as long as the contrast parameter can reach more than 3000 projectors, used to set up a home theater can have a good performance, watching movies, 16: 9 big screens are fun. Therefore, it is necessary for interested friends to pre-wire the projector's line in advance. The large-screen HD home theater is a trend. Because the HD cable is relatively thick, it must be threaded with a thick PVC pipe. It is better to connect more than two (HDMI) HD cables to the cable of the projector, because the plug of the HD cable may be damaged due to repeated plugging and unplugging. When you get to the wall again, you won't be able to pay for it; you can also put a color line and VGA cable at the same time, because the equipment will continue to increase and update to be prepared.
The wiring method of the wire can be extended from the TV cabinet to the floor, and then to the back wall. There is a special HDMI plug-in board on the market, the wire is connected to the rear and the two ends are connected to the plug-in board, and the player and the projector are used in short HD. The cable can be plugged into the terminal block. However, this will affect the transmission quality of HDMI more or less, so it is not recommended.
Third, home theater audio cable wiring:
Home theater audio has more wires, and it is also divided into audio model lines and speaker cables. Pay attention when wiring.
1. Audio cable: The audio cable transmits sound signals. It also needs to be amplified by the circuit to make sound. In home wiring, the main consideration is the subwoofer's audio input. If the subwoofer is an independent amplifier, you need to output a bass audio signal from the 5-channel amplifier to the subwoofer; most subwoofers are placed. The left or right side of the TV cabinet is placed against the wall. Therefore, an audio cable (coaxial cable) is embedded in the TV cabinet position to the left or right. The ends of the TV cabinet are fixed to the wall with the socket of the RCA terminal, and can be inserted and removed at will. Although a good subwoofer has no sense of direction, it is better to be able to put it on the left side. Other audio video cables are connected to the TV through PVC pipes, or directly connected to amplifiers and playback devices. Since the wires are short, no wiring is required.
2, speaker cable, commonly known as speaker cable.
The home theater is generally divided into 7.1 channels and 5.1 channels. In general, the living room and the independent viewing room with a viewing distance of less than 10 square meters are recommended. 5.1 is recommended. If the 7.1 position is unreasonable, the sound will be more chaotic, and the sound painting will be out of touch. The feeling of watching a movie will be worse.
The .1 in 5.1 or 7.1 refers to the subwoofer. The wiring method has been explained above, so only 7 or 5 speaker cables are required. The front is the front left and right speakers, the left and right distance is between 2 and 3.5 meters. If it is combined with the large screen projection, the left and right distances can be extended to the sides of the screen. Also, the connection socket is used to mount the wall, and the middle is used for the tube; The speaker can be connected directly to the amplifier without wiring. The surround speaker is about 1.5 meters on the back wall of the sofa. As for the height and the problem of placing the side wall and the back wall, it can be placed according to the actual situation, not too much, but it must be at the position above the back of the ear. The emerging rear center surround speaker is now parallel to the rear surround, positioned just behind the listening position:
