1、插座接触不良、信号线接触不良。要检查清楚音箱通电、各个信号线接触良好。
1, poor contact socket is bad, the signal line. To check a clear speaker power, each signal line contact is good.
2、济南音响功放最常见的故障就是坏电容或烧功放管了，这有我们使用的问题，但大部分还是设备本身不稳定了。
Fault 2, Ji'nan audio power amplifier is the most common bad capacitors or burning power tube, which is the problem we use, but most of it is the device itself unstable.
3、有些功放会发生一个通道没有声音的故障，问题还是里面电路问题。
Fault 3, some power amplifier will occur a channel without sound, the problem or the circuit problem.
4、至于其它故障还有什么功放音量电位器接触不好、左右声道不平衡、保护功能太频繁、后面板工作转换开关接触不好及信号插口等问题，总之，功放是现在音箱系统中比较容易发生故障的一种电器设备。
4, as for the other fault what amplifier volume potentiometer contact is not good, the left and right channel imbalance, protection function is too frequent, the rear panel work switch contact is not good and the signal socket and other issues, in a word, the power amplifier is a kind of electrical equipment now speaker system is easier to failure.
5、济南音响部分故障最常见的当然是喇叭问题了，可以说一套音箱系统中最容易发生的故障就是烧坏喇叭，这个当然有人为因素，但大部分还是音箱本身质量问题。
The 5 most common, Ji'nan audio part of the fault is of course the horn problem, can say the most fault prone a sound system is burned speakers, this of course is the human factor, but most of it is the speaker itself quality problems.
6、音箱的另外一个常见故障就是接线端口老化，接触不良了，特别是经常流动的音箱容易发生这种故障。
6, the speaker's fault is another common wiring port aging, poor contact, especially easy to the regular flow of speakers for this failure occurs.
