在扩声领域里，音响器材的配置是十分考究的，其中功放与音箱的配置是重要的，虽然，一些音箱生品使用说明中向用户了所配功放的具体牌号或型号，但还是有局限性，因为用户经常面对诸多型号的功放，无从下手。下面
山东公共广播音响厂家就来为您讲讲公共广播中功放与音箱的配置解决方式。
In the field of sound reinforcement, the configuration of audio equipment is very exquisite, among which the configuration of power amplifier and speaker is important. Although the instructions for the use of some speaker products recommend the specific brand or model of the power amplifier to users, there are still limitations, because users often face many models of power amplifier, and have no way to start. Next, Shandong public broadcasting audio manufacturer will tell you about the configuration and solution of power amplifiers and speakers in public broadcasting.
功放与音箱的配置所涉及的方面很多，例如功放牌号、功率管类型的选择及低灵敏度音箱应配置哪种功放等。功放与音箱的具体配置，一般来说与设计人员的经验、爱好、听音习惯等因素有关，很难找到一个统一的标准。
The configuration of power amplifier and speaker involves many aspects, such as the selection of power amplifier brand, power tube type and which power amplifier should be configured for low-sensitivity speaker. The specific configuration of power amplifiers and speakers is generally related to the experience, hobbies, listening habits and other factors of designers. It is difficult to find a unified standard.
有时我们会遇到一些用户或设计人员为了节省开支常给音箱配置较小功率的功放，有些用户又为了所谓的"功率储备充足"给音箱配置很大功率的功放。显然，这样做都是不合适的。重要的是，这样配置会给设备造成损坏。在功放与音箱配置中，功放功率的确是关键，也就是说，功放功率的确定原则应该是统一的。
Sometimes we will encounter some users or designers who often configure the speaker with a smaller power amplifier to save money, and some users configure the speaker with a large power amplifier for the so-called "sufficient power reserve". Obviously, it is inappropriate to do so. It is important that this configuration will cause damage to the device. In the configuration of power amplifier and speaker, the power of power amplifier is indeed the key, that is to say, the determination principle of power amplifier should be unified.
功放与音箱的功率配置与目标响度以及所使用场合也有一定的关系。在一定目标响度下，应该让音乐信号的动态在每件器材上都能得到充分的保证，如果功放功率太大，其增益设置很小时，响度已达到要求，但这时功放的增益就限制了信号的动态范围。所以，功放功率不能太大；否则，既然浪费开支，又会带来响度和音乐动态无法兼顾以及音箱负荷过重的麻烦。
The power configuration of power amplifier and speaker is also related to the target loudness and the use occasion. Under a certain target loudness, the dynamic of the music signal should be fully guaranteed on every device. If the power amplifier is too large and its gain setting is too small, the loudness has reached the requirements, but at this time the gain of the power amplifier limits the dynamic range of the signal. Therefore, the power amplifier should not be too large; Otherwise, since the expense is wasted, the loudness and music dynamics cannot be taken into account and the speaker is overloaded.
根据以往经验，一般语言、音乐扩音场所和大动态的迪厅等场所是有区别的。有一般扩音场所信号起伏小，不需要功放长时间或很快提供很大电流给音箱，所以功放功率应该比要求强劲有力的大动态扩音场所的功率要小；另外，所谓的"功率储备"也应该针对音箱而言，值得注意的是，功放的选定须由音箱决定，不应该有"功率储备"的概念去配置功放。
According to past experience, there are differences between general language, music amplifying places and large dynamic discos and other places. There is little signal fluctuation in general public address places, and it is not necessary for the power amplifier to provide a large amount of current to the speaker box for a long time or soon, so the power of the power amplifier should be smaller than that of the large dynamic public address places that require strong power; In addition, the so-called "power reserve" should also be targeted at the speaker. It is worth noting that the selection of power amplifier must be determined by the speaker. There should be no concept of "power reserve" to configure the power amplifier.
在一定的目标响度下，音箱可以比设计值大一些，以备不同用途，而功放的功率应该严格由音箱决定，没有太大的灵活性。总之，功放与音箱功率配置的具体标准应该是：
At a certain target loudness, the speaker can be larger than the design value for different purposes, and the power of the power amplifier should be strictly determined by the speaker, without much flexibility. In short, the specific standards for power allocation of power amplifier and speaker should be:
在一定阻抗条件下，功放功率应大于音箱功率，但不能太大。在一般应用场所功放的不失真率应是音箱额定功率的1.2-1.5倍左右；而在大动态场合则应该是1.5-2倍左右。参照这个标准进行配置，既然能保证功放放在佳状态下工作，又能保证音箱的，即使对经验不足的操作人员，只要不是操作严重失误或前级周边设备调校不当，就能让音箱和功放工作在稳定状态。更多相关内容就来我们网站

Under certain impedance conditions, the power of the power amplifier should be greater than the power of the speaker, but not too large. In general applications, the distortion rate of power amplifier should be about 1.2-1.5 times of the rated power of the speaker; In large dynamic situations, it should be about 1.5-2 times. The configuration according to this standard can ensure that the power amplifier works in a good state and the safety of the speaker. Even for inexperienced operators, as long as it is not a serious error in operation or improper adjustment of the previous peripheral equipment, the speaker and power amplifier can work in a stable state.
