The PA system (Public Address System) is mainly divided into the following categories, each type differs in application scenarios, performance and characteristics:
Traditional PA system: mainly composed of sound source, power amplifier, speaker and controller. The sound source can be a CD player, radio, microphone, etc. The power amplifier is used to amplify the sound source signal, the speaker is used to convert the signal into sound, and the volume and sound quality are adjusted through the controller. The traditional PA system has high-quality sound quality and transmission stability, suitable for small and medium-sized places.
Digital PA system: using digital signal processing technology, it can achieve precise control and adjustment of sound, with higher sound quality and more accurate sound positioning effect, suitable for large venues such as stadiums and theaters, and can meet the requirements of high sound quality and long-distance transmission.
Portable PA system: usually composed of an integrated speaker, microphone and power amplifier, small size, light weight, easy to carry and install, suitable for outdoor activities, speeches, weddings and other occasions that need to be set up quickly.
