Home Theater Audio Wire Category and Purchase Knowledge
Sofa Stewardship Home Theater Introduction With the improvement of people's living standards, more and more families have home theater audio equipment, and they all want perfect sound performance. However, most users put budgets on speakers, amplifiers, or projections. However, it ignored the impact of wire rods on the entire theater system. Today, the author will share relevant knowledge about home theater wire in order to obtain higher quality sound effects when building a home theater in the future.
The importance of wire to home theater
Wires transmit signals in the sound and act as “bridges†and are therefore crucial. Good sound lines and poor sound lines are not only different in material grades, but also have different internal structural principles, so there is a difference in the performance of the signal transmission and resistance to external electromagnetic interference. High-end audio matching high-end audio cable, mid-range audio matching mid-range audio cable, low-grade audio matching low-grade audio cable, which is the most reasonable investment principle to ensure that the best sound effects.
Someone bought a high-end audio, but in order to save money and matching low-end audio line, this is no different from the start of the Mercedes-Benz car to the gas station plus the cheapest 90 # gasoline - on the surface to save money, in fact, the effect is not the best, Wasted high-end audio and wasted Mercedes. Usually in the high-end audio configuration, the audio line accounted for 15% to 30% of the investment is more reasonable.
Home Theater Cable Classification
1, audio and video lines
AV cable: The most "old" cable for transmitting analog audio and video signals.
S-Video line: It is used to transmit analog video signals and the transmission quality is better than the AV cable.
Color-difference components: Analog video cables with the best transmission quality, DVD, TV, and projector all have such ports.
VGA cable: An analog video cable suitable for computers. It must be equipped if you want to use a TV as a computer monitor.
DVI cable: Fully called the Digital Visual Interface, for the transmission of digital video signals without compression, equipped with more DVDs, TVs, and projectors.
HDMI cable: The full name is Hi-Definition Multimedia Interface. Compared with DVI, it increases the transmission of uncompressed audio signals, so it will replace DVI in the future. Of course, for those devices that originally had a DVI port, HDMI-DVI converters or patch cords would be compatible with each other.
Coaxial digital line: The appearance is the same as an ordinary AV cable, and sometimes it can also be used as an AV cable to transmit digital audio signals.
Optical fiber digital cable: It has the same function as the coaxial digital cable, but it is different from the transmission carrier.
Microphone cable: Line used to connect the amplifier, karaoke reverberator and microphone. The range of applications is limited and wireless microphones are also available.
From the current point of view, the complete audio and video cabling should consider the AV line, color difference component line and HDMI line.
The AV cable is the most popular and commonly used; the color difference cable is suitable for connecting DVDs, satellite TV tuners and televisions or projectors, especially wall-mounted flat-panel TVs and projectors, which need to be pre-wired in the wall. Buried; HDMI cable can be used to replace the AV cable, color component cable and DVI cable, but the current video equipment supporting HDMI port is not enough popular.
As for other types of wire rods, since the transmission distance between them is usually not very long, it is possible to consider directly connecting the video and audio equipment.
2, speaker cable
In home theaters, the speaker cables for surround channels are usually led from the AV amplifier/multi-channel rear stage in the front audio cabinet, and then connected to the surround speakers in the back wall. They must be renovated for the sake of cleanliness and aesthetics. Pre-buried. However, the speaker lines of the main channel and the center channel are usually relatively short, so basically do not need to be embedded.
3, power line
DVDs, AV amplifiers, and TVs, as well as the projector itself, come with power cords. For those users with higher requirements, you may consider replacing the original split-type power cable with a better material.
Home Theater Audio Basic Requirements for Wire
1, good contact
Good contact wire is very smooth and uninterrupted when transmitting signals. If the contact performance is not good, the quality of audio image signal transmission will be reduced, or the signal transmission will be interrupted. Consumers are absolutely unacceptable.
2, good durability
When we use a variety of home theater audio equipment, due to different factors such as changing the placement, changing equipment, and maintenance, the wire will be connected multiple times. This requires testing of the durability of wire rods. Excellent quality wire rods do not suffer from poor contact due to repeated insertions and withdrawals.
3, low transmission loss
The transmission loss is also an important factor in evaluating the quality of the wire. The main function of the wire is to transmit the signal, and its own material and structure may cause signal loss or distortion, thereby causing sound staining. Therefore, the impedance of the excellent quality wire itself should be well matched with the home theater audio equipment, so that the signal can be transmitted in a true and complete manner. This is also the ultimate goal pursued by high-quality wire rods.
4, good shielding performance
The wire itself will prevent electromagnetic interference from the surrounding electronic equipment through techniques such as radiation protection and shielding isolation. This kind of electromagnetic interference is not likely to be avoided in daily life. Therefore, the radiation protection and shielding isolation effect of the wire itself is poor, and it may interfere with normal audio and video signals. This is not a result acceptable to consumers.

Wires that do not cut corners are good things. There is no need to pursue branded high-grade wire unless you are not bad. There is no embedded HDMI interface during the renovation, there are wireless HDMI this magical thing can be used, but a set of more than 1000 is required to be reliable.
For the speaker cable, the purity is high, and the thicker wire is a good thing—note that it is not the outer diameter but the diameter of the inner core.
