A set of excellent audiophile equipment, it is necessary to configure high-end wire, and what grade of wire to choose, the production material of the wire and the impact of the production process on its overall quality, etc. A series of questions should be linked to the grade of the equipment itself. A set of cheap audio using high-level cable tree and the use of ordinary cable is not much different from the replay, and a set of high-end audio using high-grade cable and the use of ordinary cable replay quality is obvious difference. The difference between this small difference and the obvious difference is determined by the quality of the audio equipment itself. But from another point of view, if you want to use only a few high-end audio lines to significantly improve the replay effect of low-end audio equipment, it is unrealistic; and in a reasonable set of middle and high-end equipment, ignore The configuration of the wire will directly limit the full play of the potential of the audio equipment, and the sound quality and resolution of the replay will be affected to a certain extent. Therefore, it is necessary to correctly understand the position of the wire in the audio system.
On the surface, the resistance value of the good wire and the poor wire is very small when the DC signal is passed, and there seems to be no big difference. In fact, this is a simple mistake. Because the signals replayed by audio equipment are alternating signals of different frequencies, rather than constant DC signals, when transmitting audio signals, the transmission of good wires is accurate, the frequency range of transmission is wide, the performance is true, and the level is rich; The signal transmitted by the relatively poor wire will change with the change of frequency, and the signal distortion procedure will also vary according to the frequency band. The difference between the two wires will be relatively obvious at this time. Fever audio cables can be basically divided into three categories: signal cables, speaker cables (speaker cables), and power cables.
Fever signal line
The signal line is a wire used to transmit the acoustic signal generated by the sound source (signal source). It mainly includes coaxial signal cable (RCA) (AV signal cable), digital signal cable, cable signal cable, balanced signal cable.
Coaxial signal cables are the most popular standard signal cables. Both ends of them are RCA coaxial plugs (commonly known as lotus plugs). They can be used for standard disc players, CD players, VCD players, DVD players, LD players, etc. Audio sources such as decks, tuners, LP players, MD, etc. are connected to audio processing / amplification equipment such as HI-FI fever amplifiers, AV functions, etc. This line is widely used, is an unbalanced transmission type, and has certain anti-drying capabilities.
The digital signal line is a kind of coaxial signal line. It has the same appearance as the coaxial signal line and can be used in series with each other. Unlike the coaxial signal line, it has a fast transmission rate, a transmission frequency bandwidth (in the video range), and strong anti-interference ability. The main purpose of the digital signal cable is to connect the CD turntable and the D / A converter (digital / analog converter) to transmit a single digital signal in high-end equipment, and the digital output of the DVD to the D / A converter of the AV amplifier Signal transmission.
The optical fiber (cable) signal line has the same function as the digital signal line, except that it transmits the digital optical signal from the CD turntable / DVD player. Because the digital electrical signal is converted into electric light in the CD turntable, it becomes the optical signal transmitted in the optical fiber, and because the optical signal transmitted in the optical fiber signal line is not affected by the external electromagnetic wave, and the optical fiber transmission can make both There is no common grounding between the signals, and there is no common grounding to avoid the interference of the common ground wire, so the anti-interference ability of the optical fiber signal line is stronger than the digital signal line. The optical fiber signal line uses an optical fiber plug, which is made of optical fiber and is afraid of folding. When using it, try to avoid bending and vibration.
