一.輸出形式區別：1.定壓吸頂音箱的額定電壓不定，定壓系統的音箱以并聯的形式連接，只要音箱的總功率不超過定壓功放的總功率，可以連接
1、 Difference in output form: 1. The rated voltage of a constant voltage ceiling speaker is variable, and the speakers of a constant voltage system are connected in parallel. As long as the total power of the speakers does not exceed the total power of the constant voltage amplifier, they can be connected

1、 Differences in output formats:
、定壓吸頂音箱的額定電壓一定。定壓系統的音箱以并聯的形式連接，只要音箱的總功率不超過定壓功放的總功率，可以連接很多只吸頂音箱，一臺功放可以連接一層樓的吸頂音箱，也可以連接一棟樓的音箱。只要不超過功放的總功率即可。
The rated voltage of a fixed pressure ceiling speaker is fixed. The speakers of the constant pressure system are connected in parallel, as long as the total power of the speakers does not exceed the total power of the constant pressure power amplifier, many ceiling speakers can be connected. One power amplifier can be connected to a ceiling speaker on a floor or a speaker on a building. As long as it does not exceed the total power of the amplifier.
、 定阻吸頂音箱，需要與定阻功放輸出阻抗進行匹配，定阻系統負載電阻一定。 在定阻功放中如果負載阻抗發生變化，功率就發生相應變化。8歐姆100W的定阻功放接4歐姆就變成接近200W。定阻功放連接定阻吸頂音箱，不可隨意增加，需要工程師計算后才可增加。
The fixed resistance ceiling speaker needs to be matched with the output impedance of the fixed resistance amplifier, and the load resistance of the fixed resistance system is fixed. If the load impedance changes in a fixed resistance power amplifier, the power will change accordingly. A fixed resistance power amplifier with 8 ohms and 100W becomes close to 200W when connected to 4 ohms. The fixed resistance amplifier is connected to the fixed resistance ceiling speaker and cannot be added arbitrarily. It needs to be calculated by an engineer before adding.
定壓音箱和定阻音箱的區別
The difference between constant pressure speakers and constant resistance speakers
、定壓音箱與定阻音箱音質區別
Differences in sound quality between constant pressure speakers and constant resistance speakers
定壓音箱用在要求音質不是很高的大空間，反之定阻由于傳輸的限制只能傳輸100米以內，故一般用在小空間時音效相對要好的多。因為定壓功放在電路上使用了變壓器，所以其音質受到了一定的影響。但是如果選用的廣播音箱可以提高廣播系統的音質
Fixed pressure speakers are used in large spaces that do not require high sound quality, while fixed resistance speakers can only transmit within 100 meters due to transmission limitations. Therefore, the sound effect is generally much better when used in small spaces. Because the constant voltage amplifier uses a transformer in the circuit, its sound quality is affected to a certain extent. But if the selected broadcasting speaker can improve the sound quality of the broadcasting system
