1. The normal working temperature of professional audio equipment should be 18~45℃. If the temperature is too low, some machines (such as tube machines) will become insensitive, and if the temperature is too high, it is easy to burn out the components or prematurely age the components. In summer, special attention should be paid to cooling and maintaining good ventilation.

2. Avoid direct sunlight to the audio equipment, and do not place it near heat sources such as heaters.

3. After the professional audio equipment is used up, reset the function keys. If the function key is not in place for a long time, the tension button spring will be under force for a long time, which is easy to cause misoperation.

4. Before turning on or off the audio power, turn down the volume potentiometer of the power amplifier, which is an effective means to protect the power amplifier and speakers. At this time, the power of the power supply is close to zero. In case of failure, at least there is no harm to the speaker. Professional stage audio equipment

5. When turning on the power, connect it from front to back. That is to say, turn on the CD player first, then turn on the front and rear ends. When turning on the power, turn down the volume potentiometer of the power amplifier. When turning off the power amplifier, please turn off the amplification function of the power amplifier. If the front-end equipment is turned off at this time, no matter how much inrush current occurs, the amplifier and speakers will not be affected. Similarly, when the power amplifier is turned off, the volume potentiometer of the power amplifier is turned down.

6. The machine must be used frequently. It can prolong the life of the machine, such as some parts with motors (burners, laser players, laser DVD players, etc.). Machine parts will be deformed if they are not rotated for a long time.

7. Turn on the power regularly. Leave it on for about 30 minutes a day, especially when not in use for a long time, especially in hot and humid seasons. In this way, the heat generated by the internal components of the machine can be used to remove moisture and prevent the internal coils, speaker coils, transformers, etc. from being damp and mildewed.

8. Regularly wipe the surface of the equipment with a clean damp cotton cloth. When not in use, cover the device with a dust cover or cloth to prevent dust from entering the device.
