How to maintain home theater audio-visual speaker equipment

2022-12-12 10:31:51

Professional audio-visual speaker equipment also requires special technical processing. The maintenance and use of home theater audio-visual speaker equipment are very particular. Once improperly operated, the speaker equipment may be damaged. Analysis of ten common senses for daily maintenance of home theater audio-visual portable smart speakers.

1. Before switching on and off the power of the portable smart speaker, turn the volume potential of the power amplifier to the minimum, which is to protect the power amplifier and the portable smart speaker.

2. The normal working temperature of home theater audio-visual portable smart speaker equipment should be 18°C to 45°C. If the temperature is too low, it will reduce the sensitivity of some machines; if it is too high, it will easily burn out the electronic components, or make the electronic components age prematurely. Avoid direct sunlight and keep away from heat sources.

3. After the audio-visual portable smart speaker equipment is used up, its function keys must be reset. If it is not reset for a long time, its button spring is under stress for a long time, which will easily cause malfunction.

4. When the home theater audio-visual portable smart speaker equipment is turned on, turn it on from the front to the back, that is, first turn on the DVD player, then turn on the front and rear stages, and turn the volume potential of the power amplifier to the minimum when turning it on. When shutting down, turn off the power amplifier first, so that the amplification function of the power amplifier is completely turned off. At this time, when you turn off the front-end portable smart speaker equipment, no matter how large the inrush current is generated, it will not affect the power amplifier and portable smart speaker.

5. The audio-visual portable smart speaker equipment of the home theater should be used frequently. If it is not rotated for a long time, some parts will be deformed. In the case of long-term non-use, especially in humid and high-temperature seasons, it is best to turn on the power for half an hour every day. In this way, the heat generated by the internal components of the machine can be used to drive away moisture, so as to prevent the internal coil, portable smart speaker voice coil, transformer, etc. from being damp and moldy.


6. Clean and maintain the contacts every six months. Soon after the metal is exposed to the air, the surface layer will oxidize. Even if the surface of the signal cable plug is gold-plated, due to the close contact with the body plug, there will still be a certain degree of oxidation after a long time, so it needs to be cleaned and maintained every six months at most. When not in use, cover the machine with a dust cover or a drape to prevent dust from entering.

7. Do not drive the power amplifier to connect the portable smart speaker wires, because the portable smart speaker wires are generally very close to each other, and the portable smart speaker wires are two tightly parallel. When wiring, the portable smart speaker wires are often short-circuited accidentally, and the consequences will be Burn the power amplifier quickly.

8. Only play some soft music and listen to music at a medium volume within half an hour of starting the machine, and then turn on the volume to listen to the machine after it warms up.

9. Other household appliances and computers should avoid sharing a power supply with the portable smart speakers. Even if they are to be put together, they should obtain power from other sources. Also, getting the cables tangled can cause the wires to absorb noise from each other, ruining the sound quality. Therefore, whether it is equipment or connecting lines in the home theater, it should be kept free from interference from other electrical appliances or power lines.
