Audio lesson: How to maintain audio?

Scientific maintenance of audio equipment is the key to prolong its life. The following describes some basic knowledge about routine maintenance:
1, the normal operating temperature of audio equipment should be 18 ° C ~ 45 ° C. Too low a temperature can reduce the sensitivity of some machines; Too high is easy to burn components, or make components prematurely aging.
2, audio equipment should not direct sunlight, but also to avoid close to the heat source, such as heaters.
3. After the audio equipment is used up, the function keys should be reset. If the function key is no longer positioned for a long time, its pulling button spring is in a state of stress for a long time, which is easy to cause functional dysfunction.
4, before switching the audio power supply, the power amplifier volume to the minimum, which is the power amplifier and speaker one of the most effective means of protection.
5, start from the front to the back, that is, first open the CD player, and then open the front stage and the rear stage, the power amplifier volume power to the minimum. 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 impact current will not be produced and the power amplifier and speaker.
6, the machine should be commonly used, if it is not rotated for a long time, some parts will be deformed.
7. Power on regularly. In the case of long-term non-use, especially in the humid, high temperature season, it is best to power for half an hour every day. In this way, the heat generated by the components in the machine can be used to remove moisture and avoid the internal coil, speaker voice coil, transformer and so on.
8. Wipe the surface of the machine with a clean and damp soft cotton cloth every once in a while; When not in use, apply a dust cover or cloth to cover the machine to prevent dust from entering.
9, do not open the power amplifier to connect the speaker wire, because the speaker terminal distance is generally very close, and the speaker wire is two tightly parallel, and the speaker wire is often accidentally short circuit when wiring, and the consequence will be to quickly burn the amplifier.

10, only put some soft music and listen to music at a medium volume within half an hour of starting the machine, and then turn on the loud volume after the machine is warmed up.
