Home Air Purifier,Air Purifier,Room Air Purifier,Indoor Air Purifier CIXI KYFEN ELECTRONICS CO.,LTD, , https://www.kyfengroup.com The modern home theater is composed of five parts: large-screen high-definition imaging, high-definition signal playback equipment and program source, multi-channel decoding digital surround sound amplifier, 7.1 speakers that only meet the requirements of sound reproduction, and various connecting lines.
1, large-screen high-definition imaging part - as the name suggests, first of all, the screen should be large, large enough to see the whole, but also to see the details; secondly, the image is highly clear, both the picture is perfect and realistic, and the viewer is naturally comfortable . It can be a large screen plasma TV or LCD TV with a true high definition of 720P or more.
2. The high-definition signal source part—the signal of the high-definition program source must be output through the high-definition signal or the receiving device, the digital high-definition image part is sent to the imaging device, and the digital audio signal is sent to the multi-channel decoding amplifier. HD source can be: 1) high-definition source of media file format, 2) can be Blu-ray DVD, 3) can be HD-DVD, 4) can be HD camcorder HDV, 5) can be digital HD broadcast program Sources, including digital television and satellite broadcasting, etc. The corresponding high-definition playback device is a high-definition player and a receiver.
3, multi-channel decoding digital surround sound amplifier part - with up to 7.1 eight-channel latest decoding digital amplifier, is the core of modern home theater. Multi-channel sound can maximize the actual effect of the field, that is, multi-channel sound has the most realistic reduction, presence and presence. Since the HD source is multi-channel recording, an amplifier with multi-channel decoding and amplification, whether it is replaying movie sound effects, digital TV broadcasting or playing music, is indispensable!
4, seven surround speakers and a subwoofer - seven surround sound boxes are: one in the center, two in the front, two on the side, two on the back, required to meet the full-band high-power requirements. A subwoofer is indispensable for standard configuration.
5, the last part is the wire - the channel of signal transmission and circulation! In order to transmit the signal more smoothly, whether it is a digital line or an analog line, it must be in place, especially in the wall decoration.
Home theater equipment adjustments need to be separated.
1. The power supply of the audio equipment should be separated from other electrical appliances in the home. (that is, a separate power supply from the meter alone) emphasizes two points: First, use a cable with a larger cross-sectional area as much as possible to enable a large current to pass instantaneously. Such as 4mm, or even 6mm-8mm. Second, some people have already achieved the first point, but the effect is obviously improved except for the subwoofer and the power amplifier's transient speed. Other changes are not big. This is because you must use a high-purity fever power cord. Such as 5N, or even 6N. Of course it takes a lot of money, but which one is more important? I think we must do the second thing first, even if the cross-sectional area is smaller, we must also have a high purity, preferably a shielded power cord. The shield is grounded at the meter end and the indoor end is not connected. The specific effect is more details, the music is good, the background is quiet, and the decoding resolution of the power amplifier is high. The single-core copper wire has high resolution and fast transmission speed; the multi-strand copper wire is warmer and more resistant to hearing. Welcome to Home Theater Network
2. The power supply of the sound source should be separated from the power supply of the power amplifier, that is, the sound source or the pre-stage power purifier, and the power amplifier is directly connected to the wall.
3. The power supply of the video and the power supply of the audio should be separated. For example, there is a Tsinghua 05D purifier, you put the DVD player, projector, TV box into it, and the final effect is not ideal. Solution: Either add a separate filter to the power input of the DVD player (to 10A high current, but also listen to whether it affects the audio dynamics of the disc player) to prevent EMI electromagnetic interference from the switching power supply. , pollutes the power of the projector. Either separate the projector and buy a 05D Tsinghua Purifier.
4, the speaker and the ground should be separated. The main speaker (with feet), a marble plate under the middle (to be thicker), a soft cotton pad between the marble plate and the ground (to be thinner, not too thin). To use the foot nails around the tripod, try to choose some of the surrounding tripods. Look inside to see if you can sand or soy beans.
5. The treble and bass in the main speaker should be separated. There are two meanings here. One is to choose the speaker's treble and bass with separate chambers, and the crossover is designed separately for the high-pass part and the low-pass part. Simply put, it is a speaker with a truly separate design. Second, if you have purchased the above boxes, you should try to use double-line sound lines. That is, a single speaker is an example: the treble has a + pole, a pole, the middle bass has a + pole, a pole, and here are 4 binding posts. There are two binding posts on the side of the amplifier. The speaker cable is a banana plug and a banana plug at the other end. Some are 4 binding posts, and the speaker cable is 4 banana plugs at both ends.
