Many netizens have asked about the relevant knowledge of home theater in the E-home forum, especially the basics of some basic cinema equipment purchase and matching. In order to facilitate the inquiry, I have specially arranged some home theater equipment purchase and matching knowledge skills, and I hope to help the entry-level home theater builders.
THX certification Before you understand the purchase of various equipment, as an entry-level user, it is necessary to know what is THX certification, because this will play a big role in your purchase of equipment. THX certification is mainly to provide complete quality specifications for home audio-visual equipment. An AV system consisting entirely of THX-sized equipment should achieve the following effects: full-range treble and bass; smoother and more natural sound; minimal bass distortion in the hearing range; and clearer vocal positioning.
THX-certified equipment is designed for the function of home theater. For the speaker, of course, the function of the home theater is fully considered. For the power amplifier, it should be full of power. For the audio-visual source, the quality of the image is above a certain level. The same is true, but there are many different levels of difference between the pre-decoding stage and the host.
The ideal home theater speaker for the speaker, in addition to the subwoofer, each channel is best to be consistent, although the main channel, the center surround speaker is not exactly the same in appearance and volume, but at least to ensure the unit, characteristics, sound Consistent. If the built speakers are not from the same brand, there is a big difference between them in terms of shape and tone. Because most of the dynamic and attractive movies are recorded with surround sound effects. Dynamic sound effects include both moving sounds and dramatic changes in size and sound. In order to fully express the moving sound of the entire audiovisual space, a speaker with high consistency can do it.
As a home theater, the sound system must have at least 4 channels, which are left front, right front, left rear, and right rear. It should be noted that for the entry level, there is currently no speaker that combines dynamic and meticulous sound quality, that is, speakers suitable for listening to music will lack explosive power, while speakers suitable for watching movies are lacking in sound quality. . As for the coordination between the speakers, in the purchase process, it may be more practical to listen to, a lot of comparison.
We usually say that 5.1, 7.1 channel means more than 0.1 channel, that is the subwoofer, also called subwoofer, subwoofer. The main purpose is to supplement the low frequency of the whole speaker system. If your main speaker (5 or 7) is very strong, you can also disable it. At this time, you must turn off the decoder's bass. The signal is assigned to the main speaker. But for the small main speakers, adding a heavy bass can be a good rendering of the picture.
AV amplifiers currently have a large number of AV amplifiers on the market. The high-end brands are mainly in Japan, Europe and the United States. Although there are high-end amplifiers in China, the number is not large. In general, the famous brand models in Europe and America are higher in grade, more powerful, and more expensive.
Japanese products are only a few high-end products, and the mid-priced is more popular. Recently, many cheap models have been introduced. National products are mainly based on parity, and the quality is generally around 2000. Because of the emergence of Blu-ray and HDDVD players, amplifiers capable of coping with Blu-ray and HDDVD audio formats have emerged. At present, the manufacturers of new amplifiers supporting the next-generation audio formats mainly include the three brands of Onkyo, Tianlong and Pioneer. The new amplifiers that support the next-generation audio format add a lot of new elements, the effect is better, but the price is also high, it is not recommended for entry-level cinema purchase.
The player sets up the theater, and it is still recommended to buy a DVD. Some entry-level users want to choose a DVD in one step, and the selected DVD is compatible with all formats. At present, DVD can read MPEG1, MPEG2, MPEG4, EVD-specific formats, HDV-specific formats and FLASH audio and video formats as well as MP3, WMA, CD audio, MIDI, HDCD and other audio formats. However, there is currently no DVD that has the ability to read all formats.
It should be noted that entry-level cinemas should be matched with equipment produced by the same manufacturer. One is neat and uniform, and the second is visually better. Furthermore, the products produced by the same manufacturer, the color coordination between the various pieces of equipment, and the matching of the sounds are all carefully considered by the manufacturer in advance, so that they are both beautiful and convenient in terms of visual and use. If you choose a brand like East, pick a model in the West, it is not beautiful, and the tone is not too harmonious.
