Must-know rules for safe use of home theater audio systems

1. Requirements for the use of professional home theater audio system

Electronic equipment must pay attention to the use conditions of the equipment during use, and professional home theater audio system equipment should pay more attention to the use conditions. Generally, the operating conditions and requirements of the machine will be listed in the user manual of the machine, such as:

1. Ambient temperature: -10℃--+40℃

2. Relative humidity: 50%--80%

3. Power supply voltage: 190V—240V

4. Power frequency: 50Hz—60Hz

5. Avoid using the machine in an environment with extremely low or high temperature, and avoid direct sunlight on the surface of the machine.

6. Avoid using the machine in a humid environment to avoid premature failure of internal components or premature rusting of the machine.

7. Before use, it must be confirmed that the local power supply voltage matches the machine.

2. The use environment of professional home theater audio equipment

Avoid using the machine in a dusty and vibrating environment.

There should be enough space around the machine to facilitate the heat dissipation of the machine.

For power amplifiers, special attention should be paid to keep the heat dissipation channels unblocked.

Speakers are mostly made of wood, so pay attention to moisture-proof, especially pay attention to weather changes when using outdoors, and don't get drenched in rain.

3. Points for attention in the use of professional speaker system

1. In a professional home theater audio system, attention should be paid to the sequence of power-on and power-off. When starting up, turn on the audio source and other front-end equipment first, and then turn on the power amplifier; when shutting down, turn off the power amplifier first, and then turn off the audio source and other front-end equipment. If the audio equipment has a volume knob, it is best to turn the volume knob to the minimum before turning it on or off. The purpose of doing this is to reduce the impact on the speaker when turning on and off.

2. It is strictly forbidden to pull out or plug in the signal plug while the power is on. So as not to damage the machine or speaker due to the resulting impact.

3. When you need to use professional home theater audio equipment, first turn it on correctly as required, and play music after turning it on, and observe whether the indicator light of the power amplifier is working normally. After playing for a period of time, touch the power amplifier properly with your hands to see if it is overheated.

4. If the sound reinforcement equipment makes abnormal sounds during operation, immediately turn off the power supply and stop using it. And ask experienced and qualified maintenance personnel to repair it. Do not open the machine by yourself, so as not to cause greater damage to the machine or cause electric shock accidents.

4. Pay attention to the maintenance of audio equipment

1. Do not use volatile solutions to clean the machine, such as gasoline, alcohol, etc. to wipe the surface of the machine, and use a soft cloth for dusting. And when cleaning the machine shell, unplug the power first.

2. The machine is generally not waterproof. In case it gets wet, wipe off the water stain with a dry cloth. After the water is completely dry, it can start to work.

3. Do not place heavy objects on the machine to avoid deformation of the machine.

V. Safe use of machinery and equipment

1. Do not pull out or plug in the power plug with wet hands to avoid electric shock.

2. When not in use for a long time, please pull out the power plug from the power socket.

3. Do not let iron needles, hair clips, coins and other metal conductive substances fall into the machine, so as not to damage the machine.

4. When replacing the fuse of the machine, it should be replaced strictly according to the requirements, and it is strictly forbidden to use unqualified substitutes.

5. When the machine is in use, the grounding point of the chassis should be safely grounded.

6. The machine is strictly forbidden to work under overload or short circuit conditions.

7. Generally, there is an auxiliary power socket on the back panel of the civilian power amplifier. Do not connect electrical appliances such as hair dryers and electric irons through it. It can only be used to connect audio equipment.

8. In the constant voltage power amplifier, the output terminal will have a higher output voltage, and the output terminal leads are generally longer, so it is necessary to ensure the safety and reliability of the output terminal leads during use.

Six. Pay attention to the protection of the power cord of home theater audio equipment

1. Be careful not to step on the power cord or be crushed by heavy objects.

2. Do not pull, insert or forcefully twist the power cord.

3. When pulling out the plug from the socket, grasp the plug and pull it out.

Regardless of the quality of the product, the maintenance of the product is very important. Take time as much as possible to maintain your home theater audio equipment. Treat it well, and the happiness it brings to you will appear at the critical moment to obtain the enjoyment of beauty. and avoid unexpected losses.
