A “Public Address” system is anything that amplifies sound so more people can hear it. The most basic example might be a megaphone, or single microphone and speaker, used to make someone’s voice louder. These days most PA systems are used for music too. A few things that affect choices for a PA system include:

• The kind of music or speech being played

• How loud it needs to play

• The space where it’s being used

• How portable it needs to be

• Who is running the system

• Desired sound quality and durability
