1. Cables with different functions cannot be mixed at will, for example, audio cables cannot be used instead of coaxial cables.
2. Try not to bend the AV cable when using it, and it is best to keep it away from the power supply.
3. The AV cable should be as short as possible under the premise that it is sufficient. The excess length will only increase the signal loss.
4. The size of the speaker wire should be selected according to the size of the audio power. If it is too small, the signal transmission will be stagnant, and the speaker will not produce good sound; if it is too large, the signal loss will increase, the burden of the power amplifier will increase, and the speaker will also not produce good sound.
5. The connection between the AV cable and the outside must be fastened. If the contact is poor (such as collapse, etc.), it will cause the sound to emit noise, and it will cause the components to burn out in serious cases.
6. After the AV cable has been used for a certain number of years, the metal terminals and metal cores may be oxidized, which will affect the sound effect and should be replaced according to the actual situation.
