A PA sound system is an electronic device featuring amplifiers, electronic microphones, speakers, and other associated audio-related equipment. It enhances the audible volume of either a human voice music, or another recorded sound or music source. It is used mainly in clubs, open-air concerts, workshops, schools, and various other locations where amplification is needed for a number of activities. PA systems also have the added advantage of outputting audio to different devices like radio, music keyboards, and even telephone line.
PA speakers are of different types and each one is suited for certain purposes. Some PA speakers are designed to directly emit sound from speakers into a room through speakers. These are called as true electric pa sound system. On the other hand, some use transducers coupled with magnets or loudspeakers to create the audio output. The latter types are commonly known as power PA speakers. Many home stereo owners prefer to use the latter as it produces clear and precise sound without the distortion often experienced with the former type.
Another important component of PA systems is subwoofers. PA speakers often come with built-in subwoofers. But if you plan to buy separate subwoofers, make sure that the size of the speakers can properly accommodate them. If you find it hard to handle the size of your subwoofers, you can opt for wireless PA speakers that can be controlled and placed anywhere. It is advisable to opt for high quality subwoofers to avoid any audio problems at the venue. For best results, place your subwoofers at a location away from the stage.
