BASIC PRINCIPLES OF PA MIXING

There w as a tim e w hen the P.A. system and the operator
existed only to increase the overall volu m e of the perform ers,
so that they cou ld be heard in a large room or above high
am bient noise levels. This ju st isn't tru e any m ore. The sou nd
system and the sou nd engineer have becom e an integral part
of the perform ance, and the artists are heavily d epend ent on
the operator's skill and the qu ality of the equ ipm ent.
The follow ing introd u ction to the basics of m ixing are
inclu d ed for the benefit of those u sers w ho m ay not have any
significant fam iliarity w ith sou nd equ ipm ent, and w ho are
