1）注意公共广播系统的使用条件，特别要注意以下事项：
1) Pay attention to the service conditions of the public address system, especially the following items:
避免在温度低或高的环境中使用机器，避免阳光一直直接照射机器的表面。
Avoid using the machine in low or high temperature environment, and avoid direct sunlight on the surface of the machine.
避免在潮湿的环境中使用机器，以免机内元器件过早失效或机器过早生锈。
Avoid using the machine in a humid environment to avoid premature failure of internal components or premature rusting of the machine.
在使用前必须确认当地的电源电压与本机相符。
Before use, make sure that the local power supply voltage is consistent with the machine.
2）注意公共广播系统的使用环境：
2) Pay attention to the use environment of public address system:
避免在灰尘以及震动环境中使用机器。
Avoid using the machine in dust and vibration environment.
在机器的四周应留有足够的空隙，以利于机器的散热。
There should be enough space around the machine to facilitate the heat dissipation of the machine.
对于功率放大器，应特别注意保持散热通道的畅通。
For power amplifier, special attention should be paid to keep the cooling channel unblocked.
3）公共广播系统使用中的注意点：
3) Precautions in the use of public address system:
在公共广播系统的基础知识中，应注意开机、关机的顺序。开机时，应先开音源等前置设备，再开功率放大器；关机时，应先关功率放大器，再关音源等前置设备。音响设备若有音量旋纽，开机、关机前，好把音量旋纽关小处。这样做的目的都是为了减轻开机、关机时对音响的冲击。
In the basic knowledge of public address system, attention should be paid to the sequence of starting and shutting down. When starting up, turn on the front-end equipment such as sound source first, and then turn on the power amplifier; When shutting down, turn off the power amplifier first, and then turn off the front-end equipment such as the audio source. If the audio equipment has a volume knob, turn the volume knob down before turning on and off. The purpose of this is to reduce the impact on the audio system when the machine is turned on or off.
严禁带电拔、插信号插头。以免由此产生的电冲击而损坏机器或音响。
It is strictly forbidden to pull and plug the signal plug with power. In order to avoid damage to the machine or audio system due to the electric shock.
机器工作过程中若发出异常，应立即关断电源，停止使用；操作人员如不懂维修技术，自己不要擅自打开公共广播系统，以免使公共广播系统遭受更大的损坏，或造成触电事故。
If the machine is abnormal during operation, immediately turn off the power supply and stop using it; If the operator does not understand the maintenance technology, do not open the public address system without authorization to avoid greater damage to the public address system or electric shock.
此外公共广播系统一般是不防水的，万一湿了水，要待水份干透后，才能开机工作。不要在公共广播系统上放置重物，以免公共广播系统变形。更多相关内容就来我们网站
