At present, there are many kinds of professional audio equipments, and the replacement is also changing with each passing day. So many equipments will inevitably have some various faults in the use. Jazz Dragon takes a look at common faults with professional sound systems: 

Professional audio system power failure: three-phase power supply, generally use professional audio equipment will apply for the installation of three-phase power supply, more important places will use two independent three-phase power supply, if one of the whole system is not paralyzed; even very important places will use similar to the computer "UPS" and other backup power supply, visible how the power supply is important. 

Sound, light and power supply is separated: sound system and light had better should have their respective power supply, otherwise one is easy to produce interference, and another work up is not safe.

Total power distribution: a strong power supply is not enough, but also pay attention to the power distribution; in principle, the mixer and various sound source equipment should have an independent power supply; various peripheral equipment should have an independent power supply; power amplifier and other equipments should have at least 2 independent power supply. Each independent power supply is controlled with the corresponding air switch, so that we are very convenient in the switching equipment.
