Altronics - Public Address Systems
PA: Public Address System Ideal for school, church, public speaking, party or hall.
A PA system is a sound reinforcement system enabling live performances to be heard by an audience.
In its most basic form, it usually consists of a set of stage microphones connected to a mixing console or desk. A Live Sound engineer operates the console to balance and EQ the sound from the stage. The console outputs are sent to:
1. A Front of House (FOH) power amplifier and FOH speakers for the audience,
2. A Foldback system located on stage for the performers to hear themselves.
While large PA systems are much more complex than shown below, the basic layout of equipment is similar.
Graphic Equalisers are used where shown, not to tweak the performers' sound, but to make the sound of the PA work with the acoustics of the room it is in.
