Professional audiovisual sound equipment also requires special technical treatment. The maintenance and use of audiovisual audio equipment of home theaters is very particular. Once the operation is improper, it is possible to damage audio equipment and home theater audiovisual audiovisual maintenance common sense analysis.

1. Before switching the audio power, the volume potential of the amplifier is minimized, which is the protection of the amplifier and audio.

2. The normal working temperature of audiovisual audio equipment for home theaters should be 18 ° C to 45 ° C. Too low temperature will reduce the sensitivity of certain machines; too high, it is easy to burn electronic components, or make the electronic components aging early. Avoid direct sunlight, and avoid approaching the heat source.

3. After the audiovisual audio -visual equipment equipment is used up, the function keys of each function should be reset. If it is not reset for a long time, the pull button spring is in a state of stress, and it will easily cause dysfunction.

4. When the home theater audiovisual and audio -visual equipment is turned on from the front to the back, the DVD machine is turned on, and then the front and rear levels are turned on. When the power is turned on, the volume potential of the amplifier is minimized. When shutting down, turn off the amplifier and let the amplification function of the amplifier completely shut down. At this time, when you turn off the front audio equipment, no matter how large the impact current is generated, there will be no seedlings and amplifiers and audio.

5. The equipment for audiovisual audio -visual audio -visual sounds should be commonly used. If it is not rotated for a long time, some parts will deform. In the case of long -term non -use, especially in the humid and high temperature seasons, it is best to power on half an hour a day. In this way, the heat generated by the component in the machine can be used to remove the moisture and avoid moisture and molds such as internal coils, speakers, transformers, etc.

6. Clean and maintenance contact every six months. Shortly after metal is exposed to air, the surface layer will be aerobic. Even if the surface of the signal line plug is plated, due to the close contact with the body plug, the life is over for a long time, and there will still be a certain degree of oxidation, so it is necessary to clean and maintain at most six months. When not in use, cover the dust cover or covering the machine to prevent dust from entering.

7. Do not drive the amplifier to connect the sound line, because the distance between the wiring column of the audio is generally very close, and the audio line is two tightly parallel. Fast burning the amplifier.
