Precautions for the use and maintenance of HIFI audio equipment

A set of HIFI equipment is expensive, how to make it last longer? What the old cat wants to talk about today is some basic common sense in the daily maintenance and use of audio.

First of all, pay attention to the temperature. Any electronic component has its own normal operating temperature. The normal working temperature of audio equipment should be 18 to 45 degrees Celsius. If the temperature is too high, it is easy to burn out the components or cause the components to age earlier, and if the temperature is too low, it will reduce the sensitivity of some machines (such as electronic tube machines). However, it is not often used as a home when the temperature is lower than 20 degrees, so we should pay more attention to the problem of high temperature. For example, avoid direct sunlight and avoid close to heat sources (such as heating). In summer, you must pay special attention to cooling and maintaining air circulation. At the same time, do a good job of dust removal. The accumulation of dust is not beautiful, and it also affects the heat dissipation of equipment.

Secondly, good usage habits. Turn on the CD first, then the power amplifier. The opposite is true when shutting down. The reason is to avoid the instantaneous current impact power amplifier when the CD is turned on. At the same time, it should be noted that when switching the speaker, turn the volume of the power amplifier to the minimum. This is to protect the power amplifier and audio system from damage even in case of misoperation. In addition, when the equipment is used up, the function keys must be reset.

 
Finally, talk about some misunderstandings. Some people think that if you want to extend your life, the best way is to use less. This is actually a common sense error. Frequent use of the machine under the correct premise will not cause any damage to the machine, but can extend the life of the machine. In some humid and high temperature seasons, even if it is not in use, it is best to power on the machine for half an hour a day to avoid damp components such as the speaker voice coil and transformer. If it is not turned on for a long time, some parts of the machine will work abnormally due to deformation. And another big taboo is live operation. When you use a PC, you should know the hazards of live operation. The old cat will not repeat it here, but only emphasize one point. Whether it is wiring or connecting a new device, you must make sure that it is in the device. It was done when it was closed, otherwise you just wait to buy a new one.
