What is a PA system?
Well, first off, what does PA even mean? The acronym stands for Public Address system and it involves using microphones, amplifiers, loudspeakers and related equipment to increase the apparent volume of voices, instruments or other sound sources. You may also hear this type of system called a sound reinforcement system.
We’ve all encountered PA systems in venues that feature an announcer or performers that need to be heard at a distance or over a large area. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify sources, and amplifiers and loudspeakers for louder volume or wider distribution.
Main components of a PA system
No matter how simple or complicated the PA system, it almost surely uses these five components.
- Microphones (or line inputs): to convert acoustic sound into electronic signals
- Mixing boards: to process and mix these electronic signals
- Power amp: to amplify signals
- Speakers: to deliver the sound to the audience
- In-ear monitors or speakers: to monitor the performance
What kind of PA system do I need?
Now, chances are, you’re not looking to set up an extremely complicated PA system like those used by arena rock bands. Those require highly trained professionals to set up and cost many thousands of dollars to purchase.
