Matters needing attention in the use of sound equipment

What are the matters needing attention in the use of sound equipment?

First, pay attention to the conditions for the use of the machine.

In general, the application conditions of machines are listed in the instruction manual of machines, such as:

1. Ambient temperature: -10 C --+40 C

2. Relative humidity: 50%--80%

3, supply voltage: 198V--242V

4, power frequency: 50H--60Hz

Specifically, it requires:

1. Prevent the use of machines in extremely low or high temperature environment, prevent the sun always directly shine on the appearance of the machine.

2. Prevent the use of machines in humid environments, prevent premature failure of machine components or machine rust.

3, before using, it is necessary to admit that the local power supply voltage is consistent with this machine.

Two, pay attention to the application environment of the machine.

1, to prevent the use of machines in the dust and sensational environment.

2, there should be enough space around the machine to facilitate the heat dissipation of the machine.

3, for power amplifiers, special attention should be paid to maintaining heat dissipation channels.

Three, attention should be paid to machine operation:

1, in the sound system, we should pay attention to the order of starting and shutting down. Turn on the power amplifier and turn off the power amplifier before turning on the sound source. If there is a volume button in sound equipment, it is best to turn the volume button to the minimum before turning on or off. The purpose of doing this is to reduce the impact on speakers when turning on or off.

2, prohibit electrified pull, insert signal plug. Prevent the impact and damage the machine or speaker.

3. If abnormal noise is declared during the operation of the machine, turn off the power immediately and stop using it. And ask experienced qualified repairmen to repair it. Do not turn on the machine privately to prevent the machine from being damaged or cause electric shock.

Four, pay attention to machine maintenance:

1. Do not use volatile solution to clean the machine, such as gasoline, alcohol and other wiping machine appearance, dust to use soft cloth. And when you clean the machine case, you need to unplug the power.

2. The machine is generally not waterproof, if wet water, dry cloth to wipe the water stains, until the water is dry, can start operation.

3, do not put heavy objects on the machine to prevent machine deformation.

Five, the safe use of machinery:

1, do not wet hands pull, plug power plug, to prevent electric shock.

2, if you don't use it for a long time, please pull the power plug from the power outlet.

3, do not let metal pins, hairpins, coins and other metal conductive substances fall into the machine to prevent damage to the machine.

4, replace the machine fuse, should be strictly replaced according to the requirements, prohibit the use of substandard substitutes.

5, when the machine is in use, the casing should be connected to the address safely.

6. Machines must not operate under overload or short circuit conditions.

7. Generally, there are auxiliary power sockets on the backplane of civil power amplifiers. Do not connect hair dryer, iron and other electrical appliances through it. It can only be used to connect audio equipment.

8. In the constant voltage power amplifier, the output voltage will be higher, and the output leads are generally longer, so in operation, we must ensure the safety and reliability of the output leads.

Six, pay attention to the maintenance of power lines:

1, pay attention to prevent power lines being trampled and squeezed by heavy objects.

2, avoid pulling, inserting and strongly distorting the power cord.

3. When pulling out the plug from the socket, you should catch the plug and pull it out.

In general, modern audio equipment belongs to high-tech products, must be carefully maintained, safe use, correct operation. In order to get the enjoyment of beauty and prevent accidental loss.
