In the previous article, we mentioned the common fault repair methods of power amplifiers, but in order to prevent problems before they occur and reduce the probability of failure, we need to treat power amplifiers like babies. Let's take a look at the method of protecting the amplifier.
How to maintain the power amplifier
|
1
|
Users should place the power amplifier in a dry and ventilated place, and avoid working in a damp, high temperature and corrosive environment with oil fume chemical agents.
|
2 |
The power amplifier should be placed in a safe and stable table to use, so as not to touch or fall to the ground, the machine damage or cause greater man-made disasters, such as fire, electric shock, etc.
|
3 |
The power amplifier should avoid serious electromagnetic interference environment, such as fluorescent lamp ballast aging and other radioactive electromagnetic interference will cause the machine CPU program disorder, resulting in the machine can not work normally.
|
4 |
After the power amplifier is used up, each function key should be reset. If the functional key is out of position for a long time, the pull button spring is under stress for a long time, which is easy to cause dysfunction.
|
5 |
Before switching sound power supply, the volume potentiometer of the power amplifier should be turned to the mini-mum, which is the most effective means of protection to the power amplifier and sound box. At this time the power magnification that result puts is zero almost, at least error operation won't cause very big harm to sound box.

In the case of long-term non-use, especially in the humid and high temperature season, it is best to power on for half an hour every day. In this way, the heat generated when the internal components of the machine work can be used to remove moisture, to avoid internal coil, loudspeaker voice coil, transformer and other damp mold break.

Wipe the surface of the machine with a clean and damp soft cotton cloth every once in a while. When not in use, cover the machine with dust cover or cloth to prevent dust from entering.
|

The normal working temperature of audio equipment should be 18℃ ~ 45℃. Too low temperature will reduce the sensitivity of some machines, too high temperature will easily burn components, or early aging components. Pay special attention to cooling and maintaining good ventilation in summer.
