PA Systems Mixers Speakers Mic's

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. Prices vary widely, anywhere from several hundred dollars for a little karaoke set up to several thousand dollars for just one of Bruce Springsteen’s concert speakers. 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
•     Cost

Most basic systems these days include several different parts such as:
    •        one or more microphones
•     one or more speakers
•     a “mixer” that allows the user to control the volume, tone and balance of different voices or instruments
•     an amplifier (built into the mixer, built into the speakers, or purchased separately)
•     stands to hold the speakers and microphones at appropriate height and angles
