Professional audio equipment, like people, also need maintenance. So, professional audio equipment how to do maintenance work?

Professional audio equipment maintenance the first trick:

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.

Professional audio equipment maintenance the second trick:

Audio equipment should not be in direct sunlight, but also avoid close to heat sources, such as heaters.

Professional audio equipment maintenance the third trick:

After the audio equipment is used up, all 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.

Professional audio equipment maintenance the fourth trick:

Before switching the sound power supply, turn the volume potentiometer of the power amplifier to the minimum, which is a 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.

Professional audio equipment maintenance the fifth trick:

Turn on the power from the front to the back, that is, start the CD player first, then turn on the front stage and the back stage, turn on the power amplifier volume potentiometer to the minimum. Shut down the power amplifier first, so that the amplifier amplification function is completely closed, at this time you turn off the front-end equipment, no matter how large the impact current will not happen and power amplifier and sound box. Similarly, the volume potentiometer of the power amplifier should be turned to the minimum when the surface is closed, and the CD player can be turned off or put back on.

Professional audio equipment maintenance 6 tips:

The machine should be used frequently. Commonly used but can prolong the life of the machine, such as some parts with motor (recording base, CD player, laser video player, etc.). If not rotated for a long time, part of the machine will be deformed.

Professional audio equipment maintenance the 7th trick:

Power on regularly. In the case of long-term 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 when the components of the machine work can be used to drive away moisture, to avoid the internal coil, speaker voice coil, transformer and other damp mold break.

Professional audio equipment maintenance the 8th trick:

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

Professional audio equipment maintenance 9 tips:

From the principle of electronics, any electronic equipment should not be connected or disconnected from other devices when it is live. I don't want to use too much explanation on this point, friends can understand that live plug active equipment is very dangerous, even passive equipment such as microphones do not advocate live plug and dial. It should be reminded that do not open the power amplifier to connect the speaker line, because the distance between the terminal posts of the speaker is generally very close, the speaker line is two tightly parallel, wiring will often accidentally short circuit the speaker line, the consequence will be quickly burned power amplifier. Although some power amplifier has a protection line, but some HI-FI grade pure power amplifier in order to improve the sound quality, reduce unnecessary sound dyeing, often will avoid this part of the protection measures. So "switch off and reconnect" is a rule that must be followed.

Professional audio equipment maintenance 10 tips:

Some pay attention to some friends in the amplifier heat engine will not open the volume and put some explosive music, the truth is that the power amplifier element just started in a cold state, then let its large current work to shorten its life. Therefore, it is recommended to put some soft music and listen to music at a medium volume within half an hour of starting the machine, and then turn on a large volume to appreciate after the machine is warmed up.
