音响设备的音质功能肯定比其他音响的好,音响设备在使用的时候需要注意哪些事项呢?
The sound quality function of professional audio equipment is definitely better than that of other audio equipment. What should we pay attention to when using professional audio equipment?
1、如果音响设备长时间工作在较大的输入功率的状态下,音圈可能由于温度达到一百度以上而导致音箱烧毁。因此需要有一个能保证扬声器长时间正常工作的输入电功率,即额定输入功率,这个数据在设备的资料里都会给出,重要的是在使用中要严格执行,在扩声效果不如人意的情况下应考虑改变配置,而不是简单地加大功率。
1. If the professional audio equipment works in the state of large input power for a long time, the voice coil may burn down due to the temperature reaching more than 100 ℃. Therefore, it is necessary to have an input power that can ensure the normal operation of the loudspeaker for a long time, that is, the rated input power. This data will be given in the data of the equipment. It is important to strictly implement it in use. When the sound reinforcement effect is not satisfactory, we should first consider changing the configuration rather than simply increasing the power.
2、音响设备如果使用不适当很容易引起啸叫,为了减小散射声,提高清晰度,要尽量把音箱的作用区指向受众的座位方向。
2. If the professional audio equipment is not used properly, it is easy to cause howling. In order to reduce the scattered sound and improve the clarity, we should try to point the action area of the speaker to the seat direction of the audience.
3、工作中经常同时使用多个音箱,在连接它们时一定要注意性问题,所有的扬声器应当一致,如果连接后的扬声器不同,则声音输出将相互干涉,听起来感觉低音不足,明显的不调和音。
3. We often use multiple speakers at the same time in our work. When we connect them, we must pay attention to sex. All the speakers should be the same. If the connected speakers are different, the sound output will interfere with each other. It sounds like the bass is insufficient, and there is obvious disharmony.
4、放大器与音响设备之间的功率要匹配。重放声音的综合音质不仅取决于音箱的特性,也取决于放大器的输出及负载特性。如果声音不理想,不要只想到是音箱出了问题,而应当考虑与它相连的放大系统是否存在问题。
4. The power between amplifier and professional audio equipment should match. The comprehensive sound quality of the playback sound depends not only on the characteristics of the speaker, but also on the output and load characteristics of the amplifier. If the sound is not ideal, don't just think that there is a problem with the speaker, but first consider whether there is a problem with the amplifier system connected to it.
音响设备使用安 全要点与注意事项
Safety points and precautions for the use of audio equipment
音响灯光的各个应用领域,安 全问题一直以来是大家为关注的焦点,虽然每一次安 全事故,都有不同的发生原因。但有一点是共同的,那就是生产方都忽视了现场的安 全,或者说在安 全防范上做得不到位。
In various application fields of sound and lighting, safety has always been the focus of attention, although every safety accident has different causes. But there is one thing in common, that is, the producers ignore the safety of the site, or do not do a good job in safety prevention.
对于音响设备操作人员来说,尤其要注意在使用设备的过程中的操作细节!不少用电器都是在火线的位置上有保险丝,接反会造成保险丝断后用电器依然带电的情况。
For audio equipment operators, pay special attention to the operation details in the process of using the equipment! Many electrical appliances have fuses in the position of the live wire. If they are connected reversely, the electrical appliances will still be charged after the fuse is broken.
较好能用双保险丝和双刀开关,可同时切断火线与零线。排式插座是直接连着用电设备的,在接上稳压器等保护装置确定无异常才可在关闭的状态下将各个设备接上。需要注意排插与电源的接触良好。开机前少要确认功率放大器开关是否关着且音量位置小。
It can use double fuse and double pole switch to cut off live line and zero line at the same time. The row type socket is directly connected to the electrical equipment. Only when the voltage regulator and other protection devices are connected, and it is confirmed that there is no abnormality, can each equipment be connected in the closed state. Attention should be paid to the good contact between the plug and the power supply. At least make sure that the power amplifier switch is off and the volume position is low before starting.
