Laptops have appeared in the miniaturization of computers, mp3s have appeared in the miniaturization of Walkmans, and mobile phones have appeared in the miniaturization of telephones. From people

The scientific maintenance of audio equipment is the key to extending its life. Here are some basic common sense of daily maintenance:

1. The normal working temperature of audio equipment should be 18 45 . Too low temperature will reduce the sensitivity of some machines (such as tube machines); too high temperature will easily burn out components or cause components to age early. Pay special attention to cooling and maintaining air circulation in summer;

2. The audio equipment should not be exposed to direct sunlight, and should also be kept away from heat sources, such as heaters;

3. After the audio equipment is used up, the function keys should be reset. If the function key is not reset for a long period of time, and its pull button spring is in a stressed state for a long time, it will easily cause malfunction.

4. Before turning on the audio power, turn the volume potentiometer of the amplifier to the minimum. This is one of the most effective protection measures for the amplifier and the speaker. At this time, the power amplification of the power amplifier is almost zero, at least it will not cause harm to the speaker during misoperation;

5. Turn on the CD player from the front to the back when the machine is turned on, and then turn on the front and rear stages. Turn the volume potentiometer of the power amplifier to the minimum when the machine is turned on. When shutting down, turn off the power amplifier first, so that the amplifier's amplification function is completely turned off. At this time, when you turn off the front-end equipment, no matter how much impact current is generated, it will not affect the amplifier and speakers. At the same time, turn the volume potentiometer of the power amplifier to the minimum. You can communicate with the CD player before turning it off or after turning it off;

6. The machine should be used frequently. Commonly, it can prolong the life of the machine, such as some parts with a motor (recorder, laser player, laser disc player, etc.). If it is not rotated for a long time, some parts will still be deformed;

7. Power on regularly. When not in use for a long time, especially in humid and hot seasons, it is best to power on for half an hour every day. In this way, the heat generated during the operation of the components inside the machine can be used to drive away moisture and prevent the internal coils, speaker voice coils, transformers, etc. from being damaged by moisture.

8. At regular intervals, clean the surface of the machine with a soft, moist cotton cloth; when not in use, cover the machine with a dust cover or cloth to prevent dust from entering.
