A set of high-end audio system, in addition to having excellent performance equipment components, but also need to pay attention to the mutual matching between equipment, such as the integration of the personality of the power amplifier and the speaker, but also the acoustic relationship between the speaker and the listening space.

Of course, as the "bridge" between the audio equipment, the role of the audio wire is unquestionable. The wire not only plays a functional role in power supply and signal transmission, but also a "prop" for senior audio fans to tune the sound system using different brands of wire styles.

Audio cable purchase need to know what?

First of all, understand the knowledge you need to know to buy wire

1. The shorter the length of the wire, the better, because the longer the length, the more conductive interference items.

2. The matching degree of wire with its own audio should be high, and the cost performance is high. If your audio itself is equipped with ordinary copper wire, you can buy some advanced gold-containing silver wire, and the improvement will not be obvious. 3. There are copper wire, silver wire, gold wire on the market, and you can tell which one is expensive from the material. Generally, we buy copper wire

Audio cable is divided into 100 core, 200 core, 300 core, 500 core, 600 core audio cable. Such as 100 core, that is, the audio wire composed of 100 copper cores, the more cores the better the effect, the higher the price, of course, if it is an ordinary KTV speaker line, in fact, the choice of 200 to 300 cores is enough.

The choice of speaker line has a certain amount of attention, the internal core can not be more, but also can not be less. Single-core wire strength is enough, but the separation is not good; The separation degree of multi-core wire is enough, but the strength is not enough. So there is no specific number of cores, depending on your requirements for the current speaker. Personally, the so-called separation degree is the ratio of different levels of separation sound. The higher the degree of separation, the stronger the ability to restore sound, that is, the higher the resolution!

How to square the audio cable

100 (core), the audio line on the market is generally about 0.1mm in diameter, how to square it?

Single-core cross-sectional area formula:

π*R2=3.14* radius squared.

Audio line square conversion formula is:

The conversion formula is square =3.14* (copper wire size /2) 2 * the number of unilateral gold and silver wires.

100 audio wire, copper wire is directly 0.1mm, its square is:

Square =3.14* (0.1/2) 2 *100≈0.8mm2
