Do you really understand the common sense of small stereo maintenance?

Small speakers generally refer to speakers that support or can read memory processors such as SD, TF, etc. on the market. These speaker brands have produced small speakers. At the same time, many multimedia 2.1 speakers now also have card readers. Function.

Scientific maintenance of audio equipment is the key to prolonging its life. Here are some basic common sense of daily maintenance of small audio equipment:
1. The normal working temperature of audio equipment should be 18℃～45℃. Too low a temperature will reduce the sensitivity of some machines (such as electronic tube machines); too high a temperature will easily burn out the components, or cause the components to age prematurely. Special attention should be paid to cooling down and maintaining air circulation in summer;
2. Avoid direct sunlight on audio equipment, and avoid close to 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 time, the tension button spring is in a state of stress for a long time, which will easily cause malfunction;

4. Before turning on or off the audio power, turn the volume potentiometer of the power amplifier to the minimum. This is the most effective way to protect the power amplifier and speakers. At this time, the power amplification of the power amplifier is almost zero, and at least it will not cause harm to the speakers during misoperation;
5. Turn on from front to back when turning on, that is, turn on the CD player first, then turn on the front and back stages, and turn the volume potentiometer of the power amplifier to the minimum when turning on. When shutting down, turn off the power amplifier first, so that the amplification function of the power amplifier is completely turned off. At this time, when you turn off the front-end equipment, no matter how large the inrush current is generated, it will not affect the power amplifier and speakers. Turn the volume potentiometer of the power amplifier to the minimum when the surface is closed, and it can be connected to the CD player before turning it off or after turning it off;

6. The machine should be used frequently. It can extend the life of the machine, such as some parts with motors (recording stand, laser player, laser video disc player, etc.). If it does not rotate for a long time, some parts will be deformed

7. Regularly energize. When not in use for a long time, especially in humid and high temperature seasons, it is best to energize for half an hour every day, so that the heat generated by the components in the machine can be used to drive away moisture and avoid internal coils and speaker voice coils. , Transformers, etc. are broken due to moisture;
8. Wipe the surface of the machine with a clean, damp, soft cotton cloth at regular intervals; when not in use, cover the machine with a dust cover or a drape to prevent dust from entering.
