1.0 INTRODUCTION
A public address system allows you to broadcast information to a large group of
people, whether you are giving a speech or playing live or recorded music. Public
address systems typically consist of input sources, preamplifiers, control and
monitoring equipment, and loudspeakers. Input sources refer to the microphones
that provide a sound input for the system. These input sources are fed into the
preamplifiers. The pre amplified signals are then passed into the audio power
amplifiers.
