You don’t want to be that guy shouting through a bullhorn, right? We didn’t think so. A quality public address (PA) system just says confidence, competence and, well, cool; not to mention the social power dynamics when you’re holding a microphone. So, here is a word to the wise; look for these factors when considering a PA system.
Unless your entourage has a bunch of Sherpas in it, you’re going to want a PA system that is highly portable, doesn’t weigh much and is easy to set up and take down.
You don’t need Bluetooth connectivity if the only thing you’re using the PA for is to project a speaker’s voice. Since most PA’s have multiple functions, having Bluetooth connectivity enables you to stream your audio from your smartphone or computer, a handy feature even if you’re only playing background music.
The size of the room and the number of people you need to hear what you’re broadcasting will determine how much power you need in your PA system.
