Precautions for use and maintenance of HIFI audio equipment

A set of HIFI equipment is expensive, how to make it last longer? Today, Lao Mao will talk about some basic common sense of daily maintenance and use of audio equipment.

First, pay attention to the temperature. Any electronic component has its own normal operating temperature. The normal operating temperature of audio equipment should be between 18 and 45 degrees Celsius. Too high a temperature can easily burn out components or cause them to age prematurely, while too low a temperature can reduce the sensitivity of some machines (such as tube machines). However, as a home appliance, the temperature is rarely below 20 degrees, so we should pay more attention to the high temperature problem. For example, avoid direct sunlight and avoid being close to heat sources (such as heaters). In summer, pay special attention to cooling and maintaining air circulation, and do a good job of dust removal. Dust accumulation is not only unsightly, but also affects the heat dissipation of equipment.

Secondly, good usage habits. When turning on the machine, turn on the CD first, then the amplifier. The opposite is true when turning off the machine. The reason is to avoid the instantaneous current from the CD turning on to impact the amplifier. At the same time, it should be noted that when turning on and off the audio, the volume of the amplifier should be adjusted to the minimum. This is to protect the amplifier and the audio from damage even if they are operated incorrectly. In addition, when the equipment is used up, the function keys should be reset.

Finally, let's talk about some usage misunderstandings. Some people think that in order to extend the life, it is best to use it less. This is actually a common sense mistake. Frequent use of the machine under the correct premise will not only not damage the machine, but will extend the life of the machine. In some humid and hot seasons, even if it is not used, it is best to power on the machine for half an hour every day to prevent components such as speaker voice coils and transformers from getting damp. If it is not turned on for a long time, some parts will malfunction due to deformation. Another taboo is live operation. Everyone should know the harm of live operation when using a PC. Lao Mao will not repeat it here. I just want to emphasize that whether it is wiring or connecting a new device, you must make sure that it is done when the device is turned off, otherwise you will have to wait and buy a new one.
