How do you size a PA system?

Using speakers with average sensitivity, a rock band playing in a medium-sized club will need around 1,500 watts total power at a minimum, whereas a pop or jazz group might need between 250-750 watts. For simple folk music in the same venue, that requirement can come down to as little as 60 watts.

Is one PA speaker enough?

One speaker will definitely work. Whether or not it's sufficient really depends on the size of the room and the type of coverage you require.

What amp do I need for my PA speakers?

Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.

Do bands need their own PA system?

They need a public address system, or “PA system” for short. Many venues, including auditoriums, ballrooms, and even some bars and restaurants, may already have their own in-house PA system, but if you do many live public performances, eventually you'll need a system of your own.
