Scientific maintenance of audio equipment is the key to prolong its life. The following describes some common knowledge about routine maintenance :

1, the normal operating temperature of audio equipment should be 18℃ ~ 45℃. Too low a temperature can reduce the sensitivity of some machines (such as electronic tube machines); Too high, easy to burn components, or make components early aging. Pay special attention to cool down and keep the air circulating in summer.

2, audio equipment should not direct sunlight, but also 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 no longer in position for a long time, the pulling button spring is in a state of stress for a long time, it is easy to cause dysfunction.

4. Before switching the sound power supply, turn the volume potentiometer of the power amplifier to the minimum, which is one of the most effective means of protection for the power amplifier and sound box. At this time, the power amplifier amplification is almost zero, at least in the wrong operation will not cause harm to the sound box.
