Do you know the safe use and maintenance skills of public address system? Next, Shandong public broadcasting audio manufacturer will analyze for you.
1）注意公共廣播系統的使用條件，特別要注意以下事項：
1) Pay attention to the service conditions of the public address system, especially the following items:
避免在溫度低或高的環境中使用機器，避免陽光一直直接照射機器的表面。
Avoid using the machine in low or high temperature environment, and avoid direct sunlight on the surface of the machine.
避免在潮濕的環境中使用機器，以免機內元器件過早失效或機器過早生銹。
Avoid using the machine in a humid environment to avoid premature failure of internal components or premature rusting of the machine.
在使用前必須確認當地的電源電壓與本機相符。
Before use, make sure that the local power supply voltage is consistent with the machine.
2）注意公共廣播系統的使用環境：
2) Pay attention to the use environment of public address system:
避免在灰塵以及震動環境中使用機器。
Avoid using the machine in dust and vibration environment.
在機器的四周應留有足夠的空隙，以利于機器的散熱。
There should be enough space around the machine to facilitate the heat dissipation of the machine.
對于功率放大器，應特別注意保持散熱通道的暢通。
For power amplifier, special attention should be paid to keep the cooling channel unblocked.
3）公共廣播系統使用中的注意點：
3) Precautions in the use of public address system:
在公共廣播系統的基礎知識中，應注意開機、關機的順序。開機時，應先開音源等前置設備，再開功率放大器；關機時，應先關功率放大器，再關音源等前置設備。音響設備若有音量旋紐，開機、關機前，好把音量旋紐關小處。這樣做的目的都是為了減輕開機、關機時對音響的沖擊。
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.
嚴禁帶電拔、插信號插頭。以免由此產生的電沖擊而損壞機器或音響。
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.
機器工作過程中若發出異常，應立即關斷電源，停止使用；操作人員如不懂維修技術，自己不要擅自打開公共廣播系統，以免使公共廣播系統遭受更大的損壞，或造成觸電事故。
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.
此外公共廣播系統一般是不防水的，萬一濕了水，要待水份干透后，才能開機工作。不要在公共廣播系統上放置重物，以免公共廣播系統變形。更多相關內容就來我們網站
