Microphones and Other Accessories for Public Address Systems
Public address (PA) systems aren’t just for
musicians. They’re also useful for churches, schools, bars, gyms, outdoor
sports facilities and more. With just a wired or wireless microphone, PA speakers, an amplifier and an audio mixer, you’ll be
able to project your voice or other sounds to a much larger group of people
than if you were simply talking on your own.
You can choose a wired or wireless
microphone, depending on your personal preference. A wireless microphone is often
more convenient and doesn’t present a tripping hazard, as a wired microphone can.
But you’ll need to keep the batteries charged on a wireless microphone.
There are two types of PA speakers you can choose from to project
sound. The first type, passive speakers, requires an external amplifier of some
sort. The other type, active speakers, includes an amplifier.
An audio mixer can take sounds from various sources — such as microphones,
musical instruments, MP3 players, etc. — and adjust them to be as clear as
possible. An audio mixer can also add special effects, such as reverb or delay.
Some audio mixers have an amplifier built in. An audio mixer with
an amplifier is called a power mixer. If your PA system has passive speakers
and your audio mixer lacks a built-in amplifier, you’ll likely need to add an
external amplifier to your system.
Frequently Asked Questions
Q: What does an audio mixer do?
A: An audio mixer enables you to adjust aspects of your PA system’s
sound — including volume and effects, such as reverb and delay. Mixers usually
have bass, midrange and treble controls.
Q: Do audio mixers improve sound quality?
A: Yes, an audio mixer can improve the sound quality of your PA
system. By balancing out high, low and midrange pitches or by adding audio
effects, an audio mixer can make a huge difference that your audience will
likely appreciate.
