Like people's faces, the audio system also needs daily maintenance and repair every three to five days. So, there are many matters to pay attention to in the maintenance of audio equipment. Shandong audio manufacturers will talk about them for you.
Pay attention to the environment:
The use environment of the audio equipment shall avoid using the machine in the dust and vibration environment. There shall be enough space around the machine to facilitate the heat dissipation of the machine. For power amplifier, special attention shall be paid to keep the heat dissipation channel unblocked. Most loudspeakers are made of wood. Pay attention to moisture. Pay special attention to weather changes when using them outdoors, so as not to be drenched by rain.
Pay attention to the power supply:
The audio equipment shall have a special power supply, which shall be separated from the power supply of the light. Moreover, the light prefers a lower voltage, but the audio needs a standard voltage. After the special power supply is provided, there must be stable and reliable power outlets. The "Power Sequencer" can be used as much as possible. Although the cost increases, the stability and ease of use are improved. Before switching the power supply of the audio equipment, adjust the volume potential of the power amplifier to small, which is an effective protection means for the power amplifier and the speaker.
Note the temperature:
Any electronic component has its own normal operating temperature. The normal operating temperature of audio equipment should be 18 to 45 degrees Celsius. If the temperature is too high, it is easy to burn the components or cause the components to age early. If the temperature is too low, it will reduce the sensitivity of some machines (such as electronic tube machines). However, it is seldom used at home below 20 ℃, so we should pay more attention to the problem of high temperature. For example, avoid direct sunlight, and avoid being close to heat sources (such as heating). In summer, pay special attention to cooling and maintaining air circulation, and do a good job in dust removal. The accumulation of dust will also affect the heat dissipation of equipment.
Pay attention to cleaning:
Clean the contacts every six months. The surface of metal will oxidize soon after it is exposed to air. Even if the surface of the signal cable plug is plated with gold, it will be oxidized to a certain extent after a long time because of the close contact with the body plug. Therefore, it is usually cleaned once every half a year. Smear the contact area with cotton and alcohol. When not in use, cover the machine with a dust cover or cloth to prevent dust from entering.
If the audio is not used for a long time, the battery in the remote controller should be removed to prevent the battery leakage from eroding the circuit board. Finally, pay attention when cleaning. When cleaning the outside of the equipment, it is not necessary to apply organic chemicals and organic solvents. Dry, clean and lint free soft rags can be used.
