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:
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.
、 定阻吸顶音箱，需要与定阻功放输出阻抗进行匹配，定阻系统负载电阻一定。 在定阻功放中如果负载阻抗发生变化，功率就发生相应变化。8欧姆100W的定阻功放接4欧姆就变成接近200W。定阻功放连接定阻吸顶音箱，不可随意增加，需要工程师计算后才可增加。
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.
The difference between constant pressure speakers and constant resistance speakers
Differences in sound quality between constant pressure speakers and constant resistance speakers
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
