公共廣播系統(tǒng)的使用和維護(hù)技巧你知道有哪些嗎？下面
山東公共廣播音響廠家為您進(jìn)行分析。
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(tǒng)的使用條件，特別要注意以下事項(xiàng)：
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(huán)境中使用機(jī)器，避免陽(yáng)光一直直接照射機(jī)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(huán)境中使用機(jī)器，以免機(jī)內(nèi)元器件過(guò)早失效或機(jī)器過(guò)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(rèn)當(dāng)?shù)氐碾娫措妷号c本機(jī)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(tǒng)的使用環(huán)境：
2) Pay attention to the use environment of public address system:
避免在灰塵以及震動(dòng)環(huán)境中使用機(jī)器。
Avoid using the machine in dust and vibration environment.
在機(jī)器的四周應(yīng)留有足夠的空隙，以利于機(jī)器的散熱。
There should be enough space around the machine to facilitate the heat dissipation of the machine.
對(duì)于功率放大器，應(yīng)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(tǒng)使用中的注意點(diǎn)：
3) Precautions in the use of public address system:
在公共廣播系統(tǒng)的基礎(chǔ)知識(shí)中，應(yīng)注意開(kāi)機(jī)、關(guān)機(jī)的順序。開(kāi)機(jī)時(shí)，應(yīng)先開(kāi)音源等前置設(shè)備，再開(kāi)功率放大器；關(guān)機(jī)時(shí)，應(yīng)先關(guān)功率放大器，再關(guān)音源等前置設(shè)備。音響設(shè)備若有音量旋紐，開(kāi)機(jī)、關(guān)機(jī)前，好把音量旋紐關(guān)小處。這樣做的目的都是為了減輕開(kāi)機(jī)、關(guān)機(jī)時(shí)對(duì)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(yán)禁帶電拔、插信號(hào)插頭。以免由此產(chǎn)生的電沖擊而損壞機(jī)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(jī)器工作過(guò)程中若發(fā)出異常，應(yīng)立即關(guān)斷電源，停止使用；操作人員如不懂維修技術(shù)，自己不要擅自打開(kāi)公共廣播系統(tǒng)，以免使公共廣播系統(tǒng)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(tǒng)一般是不防水的，萬(wàn)一濕了水，要待水份干透后，才能開(kāi)機(jī)工作。不要在公共廣播系統(tǒng)上放置重物，以免公共廣播系統(tǒng)變形。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站

In addition, the public address system is generally not waterproof. In case of wet water, it can only be started to work after the water is dry. Do not place heavy objects on the public address system to avoid deformation of the public address system. Come to our website for more relevant content http://m.74seba.com consulting service
