音响功能尽可能齐全，使用方便，外观华丽。购买之后也不需要用户花很多的时间去进行调试，一般来说直接就可以使用，在操作上较为方便，功能性也比较齐全。那么要如何选购舞台音响呢？需要相应原则坚持！
The sound function shall be as complete as possible, easy to use and gorgeous in appearance. After purchase, users do not need to spend a lot of time on debugging. Generally speaking, it can be used directly. It is more convenient in operation and has complete functionality. So how do you choose a stage stereo? Need to adhere to corresponding principles!
坚持实用的原则。
Adhere to the principle of practicality.
严格地讲，每一样成型了的质量过硬的产物都是实用的产物，但是实用的产物不等于什么地方场合都实用，它必须在一定的场合，配合一定的其它设备才能称为实用，否则只能是浪费、闲置。例如：设计中要未的声压和电声功率确定后，功放和音箱的功率也应该以此为依据，参考不同的用途适当增加一些.如果不考虑计算结果，照着大功率型号来选取，这就是不实用。
Strictly speaking, every formed product with excellent quality is a practical product, but a practical product does not mean that it is practical everywhere. It can be called practical only when it is combined with certain other equipment on certain occasions, otherwise it can only be wasted and idle. For example, after the sound pressure and electroacoustic power to be determined in the design, the power of the power amplifier and speaker should also be based on this, with reference to different uses It is impractical to choose according to the high-power model without considering the calculation results.
坚持适用的原则。
Adhere to applicable principles.
同样要说具体的哪一个设备是否适用，是不太确切的，只能说某个设备的选用不适合某一个具体的场合二适用性主要取决于工程的用途和特点。与实用性不太一样的是，选型实用性不高，设备也许还偶尔用得着；要是适用性不好的话，设备基本上是浪费。
Similarly, it is not accurate to say whether a specific equipment is applicable. It can only be said that the selection of a certain equipment is not suitable for a specific occasion. II. Applicability mainly depends on the purpose and characteristics of the project. Different from the practicality, the model selection is not practical, and the equipment may be used occasionally; If the applicability is not good, the equipment is basically a waste.
例如：为一个娱乐用的歌舞厅配备专来录音用的8轨录音机，似乎就不太适用；为一个面积不大的舞台设置大型演出用的子500奥迫光或1000奥的星空灯，同样也是不适用。要避免不适用的错误，不光需要设计人员对多数设备的特点有的了解，而且需要在工程的设计选型中充分向用户进行设备性能的介绍。
For example, it does not seem appropriate to equip a song and dance hall for entertainment with an 8-track recorder specially for recording; It is also not applicable to set 500W forced light or 1000W star lights for large-scale performances for a small stage. To avoid inapplicable errors, designers need not only to have a comprehensive understanding of the characteristics of most equipment, but also to fully introduce the equipment performance to users in the design and selection of the project.
要保持设备档次性能的一致性。
The consistency of equipment grade and performance shall be maintained.
具体讲就是：在所焦的一系列
山东舞台音响灯光设备中，基本上应该使它们的风格一致，价位相当，性能统一，或者说般配。因为许多产物都有一些与之有较好搭配的相关设备，而且这些搭配方式都经过了许多人士的检验，所以要做到&濒诲辩耻辞;般配&谤诲辩耻辞;这点并不难，是设计人员要有丰富的经验，否则只能是凭感觉去选配，这样就难免有不统一的地方。
Specifically, in the series of Shandong stage audio and lighting equipment, they should basically have the same style, the same price, the same performance, or a good match. Because many famous products have some related equipment that are well matched with them, and these matching methods have been tested by many professionals, it is not difficult to achieve "matching". It is necessary for designers to have rich experience, otherwise they can only choose according to their feelings, which will inevitably lead to inconsistencies.
既然明确了音响的使用地点和使用目的，因此我们可以初步判断台式音响大部分情况是播放电台、流行音乐等人声内容，因此对于音响的音箱工作频段不必要求过低。通常音响系统低的表现频率可以选定在40贬锄以上，当然这是对于每只音箱仅有一只单元而言的。如果每只音箱可以保证两只单元(也有同轴音箱高低音相嵌在一起的音箱)，那么声音效果将会完善许多。就好像一件乐器始终不如一支乐队的表现力更强一样。
Since the use place and purpose of professional audio are clearly defined, we can preliminarily judge that most of the desktop audio is playing radio, pop music and other human voice content. Therefore, the working frequency band of the audio box need not be too low. Generally, the low performance frequency of the sound system can be selected above 40Hz. Of course, this is for each speaker with only one unit. If each speaker can guarantee two units (there are also coaxial speakers with high and low tones embedded together), the sound effect will be much better. It's like an instrument is always less expressive than a band.
