顯然，當廣播音箱的總功率遠小于2500W時，用上述辦法是很不劃算的。如果想使用與廣播音箱的總功率相當?shù)墓Ψ?，則應按上式計算出其輸出電壓，然后配接適當?shù)妮敵鲎儔浩鳌?/div>
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.
音箱也可以當作廣播音箱使用，但須配接“線間變壓器”，如前所述，“線間變壓器”起阻抗變換的作用，使“定阻”的音箱能在“定壓”的廣播傳輸線路中吸取同自己的額定相當?shù)墓β省?/div>
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“線間變壓器”，把數(shù)個音箱適當?shù)卮⒙?lián)起來，也能使用，但須經(jīng)過繁瑣的計算；而且在運行過程中，只要其中一只音箱損壞，系統(tǒng)就有可能顛覆（全部不響或燒毀其他音箱或燒毀功放）。
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).
用調(diào)音臺充當廣播前置放大器屬勉強可行，但調(diào)音臺通常沒有信號優(yōu)先權排序，不便于實現(xiàn)廣播系統(tǒng)備的“強行插入”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.
反過來，廣播功放和廣播音箱也可以用于音響系統(tǒng)。但由于它們都有內(nèi)置的輸出變壓器或線間變壓器，其頻響特性遠不如同檔次的功放好。
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.
廣播前置放大器用于音響系統(tǒng)也屬勉強，因為它沒有編組、均衡、效果等功能；而其優(yōu)先排序功能對于音響系統(tǒng)來說，則多半是冗余的。
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.
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.
