Do you know the basic maintenance common sense of the following home theater audio equipment

1. Before turning the speaker power on or off,

Try to adjust the volume potential of the power amplifier to the minimum, which will have a good protection effect on the power amplifier and speakers.

2. After using the speaker equipment, reset each function key;

If it is not reset for a long time, the torsion spring will be under stress for a long time, which will easily cause malfunction of the equipment.

3. The normal operating temperature of the speaker equipment should be 18°~45°. If the temperature is too low, it will reduce the sensitivity of some equipment; if it is too high, it will easily burn out the components or make them age prematurely.

Do not avoid close to heat sources, not direct sunlight.

4. When the theater audio equipment is turned on, first turn on the CD player,

Then turn on the front and back stages, and turn on the volume and power of the power amplifier to the minimum; turn off the power amplifier first when turning off the power, and turn off the amplification function of the power amplifier completely, so that when you turn off the front-end equipment, no matter how much inrush current is generated Amplifiers and speakers too.

5. Do not adjust the volume too loudly when the cinema equipment is just turned on.

Turn up the volume after the machine warms up, which can reduce the damage to the equipment.

6. Cinema audio equipment should avoid using a common power supply with other electrical appliances, because the mutual absorption of noise between the lines will destroy the sound quality;

Therefore, whether it is connecting wires or equipment, it must be kept free from interference from other electrical appliances.

7. Avoid stacking devices.

When the device is played, the two devices will interfere with the transmission of their respective frequency bands, which will cause a kind of sound pollution, which will not only affect the audio-visual but also cause damage to the equipment.

The best solution is to separate all kinds of equipment on fixed racks independently.

8. Never turn on the power amplifier to connect the speaker wire.

Because the spacing between the terminals of the speaker is generally very close, it is easy to cause a short circuit of the speaker wire when wiring, and eventually burn the power amplifier quickly.

9. It is best to use the equipment and equipment of the home theater frequently.

The long-term rotation of the equipment will reduce the service life of the equipment to a certain extent.

Especially in high temperature or humid seasons, it is best to power on for more than half an hour a day. The heat generated by the components in the equipment can drive away moisture to a certain extent and prevent the interior of the equipment from being damp and moldy.

When not in use, cover the device with a dust cover, covering cloth, etc. to prevent dust from entering the device.

10. It is best to clean and check theater equipment every six months.

Metal objects are easily oxidized when exposed to air for a long time.

he cleaning method:

Use a cotton tip to stick alcohol and directly smear the contact to clean it.
