Talk about the styles and characteristics of audio lines.

Types, selection and sound characteristics of various wires

For the power cord, in the car stereo, it is not necessary to excessively pursue the purity of copper, and the hard truth is that the wire diameter is thick enough. Personally, I think Line 6 is an entry-level power amplifier, which is suitable for one or two power amplifiers with 50W/ channel. Line 4 belongs to the normal level, and the sound pressure is average or the power amplifier pursuing heating sound is suitable for selection. Line 0~2 belongs to high power level and is suitable for high voltage or high power amplifier. Appropriate use of large wire diameter.

The benefits to the middle and low frequencies are obvious. Although the big horse-drawn car is a bit wasteful, it always has enough power.

Sound characteristics of power cord materials:

1, the whole thread is soft, and the copper wire is thin and dense, like a hair. The sound characteristics of this line are generally soft treble, mellow mid-frequency and soft bass, and masking may occur at low frequencies. This line is suitable for some equipment with thin sound base, such as some entry-level equipment. If the whole system is Japanese equipment, this line is most suitable.

2. The whole wire body is tough but not hard, the copper wire is dense, and the diameter of the single branch line has a certain thickness. The sound characteristics of this kind of line are that the high, middle and low tones have a good sense of line, the sound is neutral, and the jumping force and control force of low frequency are ideal, which is suitable for some systems with hazy sound and coarse low frequency.

3. The whole wire body is relatively hard, and the diameter of single branch line is very thick. The sound characteristics of this kind of line are tough, clear and powerful, which will have ideal performance when used in sound pressure system, but if you like listening to human voices, it will appear too rough.

Signal line, commonly known as "nerve line", requires the faithful transmission of music signals to be as sensitive as human nervous system. In car audio, the system with equipment budget less than W yuan does not need to pursue the grade of wire excessively, and good and firm mechanical contact and excellent anti-interference ability are the first choice. However, when the equipment reaches a certain level, the influence of wire on sound really appears. There are two common materials for signal lines, copper and silver. Silver is commonly used for silver-clad copper wire, commonly known as "silver-plated wire".

Viewing sound characteristics from signal line materials;

1, the voice of the silver line is mostly high-pitched and beautiful, and it is Leng Yan. The texture and bounce of the middle and low frequencies are good, but the charm and appeal of the sound are a little weak.

2, copper wire (soft) most of the sound is round, high-pitched cotton, thick alto, soft bass has a certain elasticity, listening to human voices and strings tastes quite good.

3. The sound of copper wire (hardware) is mostly neutral, and the treble resolution is good, but it will not be tight. The midrange thickness is good, but it won't be fat. Bass has the texture and bounce of silver wire, but also has the softness of traditional copper wire. The charm and appeal of sound are basically in the middle of the above two lines.
