The AV cable is responsible for the transmission of audio signals and plays an important role in the entire sound system. Good and bad sound rays not only use different materials, but also have different internal structure principles, so there are certain differences in signal transmission performance and resistance to external electromagnetic interference.

The most reasonable investment principle to ensure the best sound effect is: choose the treble line for treble, the sound line for midrange, and the bass line for bass. Some people buy a premium stereo, but they choose a low-end audio cable to save money. Driving a Mercedes to a gas station and filling it up with 90% cheaper gas makes no difference. On the surface, they save money, but they don't actually work well. They couldn't make the most of Mercedes.

Usually in a premium audio configuration, the proportion of audio cable investment is 15% to 30%, which is reasonable. Even for general audio, you can't choose a low-grade AV cable, because this will not only attenuate the signal, but also the transmitted signal is susceptible to external electromagnetic interference, which will eventually lead to sound distortion.

Audio manufacturers: Precautions for the use and maintenance of audio cables

The AV cable has the following aspects in use. If you can pay attention to it, it can not only improve the sound quality performance, but also prolong the service life of the cable:

1. Cables with different functions cannot be mixed at will, such as audio cables cannot replace coaxial cables;

2. Do not bend the AV cable when using it, try to keep it away from the power supply;

3. The AV cable should be as short as possible under the premise that it is too long. If it is too long, it will only increase the signal loss;

4. The size of the speaker wire should be selected according to the sound power. If it is too small, the signal transmission will be delayed, and the speaker will not be able to produce good sound; if it is too large, the signal loss will increase, the power amplifier will be burdened, and the speaker will not be able to produce good sound;

5. The AV cable must be firmly connected to the outside. If the contact is not good (such as collapse, etc.), it will cause noise in the sound, and even cause parts to burn;

6. After the AV cable is used for a period of time, the metal terminals and wire cores may be oxidized ("aging"), which will affect the sound effect. Replace the AV cable according to the actual situation.
