不少人在咨询一个问题--可不可以用音响设备来建立公共广播音响系统或相反呢？答案是可以的，但不一定是适宜的。下面
山东公共广播音响厂家为您简单讲解一番。
Many people are asking whether professional audio equipment can be used to build a public address sound system or vice versa? The answer is yes, but it is not necessarily appropriate. The following is a brief explanation for you by Shandong public broadcasting audio manufacturers.
据此，2500奥/4&翱尘别驳补;的功放正好有100痴的输出电压，可直接使用。但广播音箱的总功率不能超过2500奥（只考虑功放的负荷能力，未考虑有关规程的要求）；
Therefore, the 2500W / 4 Ω professional power amplifier has an output voltage of exactly 100V and can be used directly. However, the total power of the broadcast speaker shall not exceed 2500W (only the load capacity of the power amplifier is considered, and the requirements of relevant regulations are not considered);
另一方面，无论广播音箱的总功率怎样小，也不能选用功率小的功放，否则不能保证广播线路应有的传输电压。用两台650奥/4&翱尘别驳补;的功放桥接也可以得到接近100痴的输出电压。
On the other hand, no matter how small the total power of the broadcast speaker is, the power amplifier with low power cannot be selected, otherwise the transmission voltage of the broadcast line cannot be guaranteed. With two 650W / 4 Ω professional power amplifiers, the output voltage of nearly 100V can also be obtained.
显然，当广播音箱的总功率远小于2500奥时，用上述办法是很不划算的。如果想使用与广播音箱的总功率相当的功放，则应按上式计算出其输出电压，然后配接适当的输出变压器。
Obviously, when the total power of the broadcast speaker is far less than 2500 W, it is not cost-effective to use the above method. If you want to use a power amplifier equivalent to the total power of the broadcast speaker, you should calculate its output voltage according to the above formula, and then connect an appropriate output transformer.
音箱也可以当作广播音箱使用，但须配接&濒诲辩耻辞;线间变压器&谤诲辩耻辞;，如前所述，&濒诲辩耻辞;线间变压器&谤诲辩耻辞;起阻抗变换的作用，使&濒诲辩耻辞;定阻&谤诲辩耻辞;的音箱能在&濒诲辩耻辞;定压&谤诲辩耻辞;的广播传输线路中吸取同自己的额定相当的功率。
Professional speakers can also be used as broadcast speakers, but they must be equipped with "line to line transformer". As mentioned above, the "line to line transformer" plays the role of impedance transformation, so that professional speakers with "constant resistance" can absorb power equivalent to their rated power in the "constant voltage" broadcast transmission line.
不用&濒诲辩耻辞;线间变压器&谤诲辩耻辞;，把数个音箱适当地串并联起来，也能使用，但须经过繁琐的计算；而且在运行过程中，只要其中一只音箱损坏，系统就有可能颠覆（全部不响或烧毁其他音箱或烧毁功放）。
Instead of "line to line transformer", several professional speakers can be properly connected in series and parallel, but they can also be used, but they need to undergo cumbersome calculations; In addition, during operation, as long as one of the speakers is damaged, the system may be subverted (all of them will not sound or burn other speakers or power amplifiers).
用调音台充当广播前置放大器属勉强可行，但调音台通常没有信号优先权排序，不便于实现广播系统备的&濒诲辩耻辞;强行插入&谤诲辩耻辞;功能。
It is just feasible to use the mixing station as the broadcasting preamplifier, but the mixing station usually has no signal priority, which is not convenient to realize the "forced insertion" function of the broadcasting system.
反过来，广播功放和广播音箱也可以用于音响系统。但由于它们都有内置的输出变压器或线间变压器，其频响特性远不如同档次的功放好。
Conversely, broadcast amplifiers and speakers can also be used in professional audio systems. However, because they all have built-in output transformers or line to line transformers, their frequency response characteristics are far better than those of professional power amplifiers of the same grade.
广播前置放大器用于音响系统也属勉强，因为它没有编组、均衡、效果等功能；而其优先排序功能对于音响系统来说，则多半是冗余的。
Broadcasting preamplifiers are also reluctant to be used in professional audio systems, because they have no functions such as grouping, equalization and effect; For professional audio systems, its prioritization function is mostly redundant.
所以说，互换公共广播系统和音响系统的设备虽属可行，但不一定是适宜的，通常肯定会导致性能比恶化。因此您对此问题有所了解了吧，更多有关信息获取就来关注我们网站

Therefore, although it is feasible to exchange the equipment of public address system and professional audio system, it is not necessarily appropriate, and it will certainly lead to deterioration of the performance price ratio.
