With the economic development, large-scale activities have become more frequent. As an important information delivery tool in large-scale events, the public broadcasting system is also drawing more and more attention. In general, due to the wide range of applications of public broadcasting systems, complex application environments and difficult maintenance, how to effectively ensure the service life of equipment has become the focus of many users. The following Xiao Bian will briefly summarize the issues that should be paid special attention to in daily applications, so as to maximize the use of your investment.
(1) Pay attention to the conditions of use of the machine, paying particular attention to the following:
Avoid using the machine in extremely low or extremely high temperatures, avoiding sunlight shining directly on the surface of the machine.
Avoid using the machine in a wet environment to prevent premature failure of the components inside the machine or premature rusting of the machine.
Before use, make sure that the local power supply voltage matches the unit.
(2) Pay attention to the use environment of the machine:
Avoid using the machine in dust and vibration environments.
There should be enough space around the machine to facilitate the heat dissipation of the machine.
For power amplifiers, special care should be taken to keep the cooling channels clear.
(3) Points for attention in using the machine:
During use, you should pay attention to the order of startup and shutdown. When turning on the power, you should first turn on the front device such as the sound source, and then turn on the power amplifier. When turning off the power, turn off the power amplifier first, and turn off the front device such as the sound source. If the audio equipment has a volume knob, it is best to turn the volume knob to the minimum before turning it on and off. The purpose of this is to reduce the impact on the speakers during startup and shutdown.
It is forbidden to pull and plug the signal plug. In order to avoid the resulting electric shock damage to the machine or speaker.
If an abnormality occurs during the operation of the machine, the power supply should be turned off immediately to stop its use. If the operator does not understand the maintenance technology, he or she should not open the machine without authorization so as not to cause the machine to suffer more damage or electric shock.
(4) Pay attention to the maintenance of the machine:
Do not use volatile solvents to clean the machine. For example, wipe the surface of the machine with gasoline, alcohol, etc. Use a soft cloth for dust. Also, unplug the power supply before cleaning the housing of the machine.
The machine is generally not waterproof, in case of wet water, to be dry until after the boot work.
Do not place heavy objects on the machine to prevent deformation of the machine.
(5) Safe use of the machine:
Do not pull wet hands and plug the power plug to avoid electric shock.
When not using it for a long period of time, unplug the power plug from the power outlet.
Do not let metallic conductive materials such as iron pins, hairpins, and coins fall into the machine to avoid damage to the machine.
When replacing the fuse of the machine, it should be replaced strictly according to the requirements, and the use of unsatisfied substitutes is strictly forbidden.
When the machine is in use, the grounding point of the chassis should be safely grounded.
The machine must not be operated under overload or short circuit conditions.
There is an auxiliary power socket on the back panel of the power amplifier. Do not use it to connect electric appliances such as hair dryers and electric irons. It can only be used to connect audio equipment.
In constant-voltage power amplifiers, the output terminal has a higher output voltage, and the output terminal leads are generally longer. Therefore, in use, it must be ensured that the output terminal leads are safe and reliable.
(6) Pay attention to the protection of the power cord:
Care should be taken to avoid the power cord being stepped on and squeezed by heavy objects.
Do not pull, insert, and strongly distorted power cords.
When removing the plug from the socket, pull it out by grasping the plug.
