圣阳蓄电池恒压功放，多称之为定压功放，也就是说它的输出是按固定电压传输的。

Shengyang battery constant voltage amplifier, called constant voltage power amplifier, i.e. its output is at a fixed voltage transmission.

一般用于远距离扩声和一线多扬声器扩声，如:公共广播、背景音乐。

It is widely used for long distance sound reinforcement and multi speaker sound reinforcement, such as public radio and background music.

其目的是为了减小传输线路对信号的损耗。同时这种传输不存在普通功放的阻抗匹配问题，因此N多喇叭都可以共用一台功放。

The purpose is to reduce the loss of the transmission line to the signal. At the same time, there is no common impedance matching problem in the transmission, so the N multi speaker can share a power amplifier.

音响系统没有恒流功放，除了定压功放，一般所用的功放都是“定阻功放”，也就是说，它的输出和电压不相关，最重要是负载阻抗必须在功放输出阻抗范围内，比如一般功放阻抗8欧(日本功放6欧、电子管机4-16欧都有)，喇叭阻抗就要求一致或接近。

The sound system is not a constant current power amplifier, besides constant voltage power amplifier, the power amplifier is generally used "fixed resistance amplifier", that is to say, it's not related to the output voltage and the load impedance is the most important, must be in the power amplifier output impedance range, such as the general power amplifier impedance of 8 ohms (6 in Europe, Japan power electronics the machine has 4-16 Europe), speaker impedance requires the same or close to.

家庭用功放都是定阻功放，定阻功放由于传输线路中少了变压器，音质更好，频率响应和动态范围都比同价位定压功放优越。

Home power amplifier are fixed resistance amplifier, fixed resistance amplifier due to the transmission line of less transformers, better sound quality, frequency response and dynamic range than the same price fixed voltage amplifier superior.
