Safety knowledge of audio equipment

Audio equipment consists of sound source, control equipment, audio processor, power amplifier and sound box. The following is the safety knowledge of audio equipment. Welcome to read and enjoy.

First of all, pay attention to the operating conditions of the machine.

1. Prevent the machine from being used in an environment with extremely low or high temperature, and prevent the sun from always shining directly on the appearance of the machine.

2. Prevent the machine from being used in a humid environment, and prevent the parts in the machine from failing prematurely or the machine from rusting prematurely.

3. Before use, it must be confirmed that the local power supply voltage is consistent with this machine.

4. The equipment used in the hotel is relatively dry in winter, especially the simple static electricity. Humidity should be added near the equipment to prevent static electricity.

2. Pay attention to the operating environment of the machine.

1. Prevent the machine from being used in dust and vibration environment.

2. There should be enough open space near the machine to facilitate the heat dissipation of the machine.

3. For the power amplifier, special attention should be paid to dredge the cooling channel.

3. Precautions for machine operation

1. In the sound system, pay attention to the sequence of startup and shutdown. Turn on the front equipment such as audio source before turning on the power amplifier; When shutting down, the power amplifier should be turned off first, and then the front equipment such as audio source should be turned off. If the audio equipment has a volume knob, it is best to turn it off to the minimum before switching it on. The purpose of this is to reduce the influence on the speaker when it is turned on and off.

2. It is forbidden to plug the signal plug with electricity. Prevent the resulting impact from damaging the machine or sound box.

3. If the machine makes abnormal noise during operation, turn off the power immediately and stop using it. And ask experienced qualified repairmen to repair it. Don't turn on the machine without permission, in case of greater damage or electric shock to the machine.

4. Pay attention to the maintenance of the machine

1. Do not clean the machine with volatile solution. For example, use gasoline, alcohol, etc. Scrub the surface of the machine and wipe the dust with a soft cloth. And unplug the power supply before cleaning the casing.

This machine is usually not waterproof. If it is wet, please dry the water stain with a dry cloth and wait until the water is completely dry before starting the operation.

3. Don't put heavy objects on the machine to prevent the machine from being deformed.

Verb (abbreviation for verb) Safe use of machines.

1. Never plug in the power supply with wet hands to prevent electric shock.

2. When not used for a long time, please unplug the power plug from the power socket.

3. Don't let iron needles, hairpins, coins and other metal conductive substances fall into the machine to avoid damaging the machine.

4. When replacing the machine fuse, it should be replaced in strict accordance with the requirements, and bad substitutes are strictly prohibited.

5. When using the machine, the shell address should be safely grounded.

6. It is forbidden for the machine to work under overload or short circuit.

7. Usually, there are auxiliary power sockets on the backboard of civil power amplifiers. Don't connect electric appliances such as hair dryers and electric irons through them. It can only be used to connect audio devices.

8. In the constant voltage power amplifier, the output terminal will have a high output voltage, and the output terminal lead is usually very long, so it is necessary to ensure the safety and reliability of the output terminal lead in the work.

6. Pay attention to the maintenance of the power cord

1. Pay attention to prevent the power cord from being crushed by heavy objects.

2. Do not pull, plug and strongly twist the power cord.

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