A public address system (PA system) is an electronic
sound amplification and distribution system with a
microphone, amplifier and loudspeakers, used to
allow a person to address a large public, for
example for announcements of movements at large and
noisy air and rail terminals.
Simple PA systems are often used in small venues
such as school auditoriums, churches, and small
bars. PA systems with many speakers are widely used
to make announcements in public, institutional and
commercial buildings and locations. Intercom
systems, installed in many buildings, have
microphones in many rooms allowing the occupants to
respond to announcements.
Public Address (P.A) systems combine the very latest
technology in amplifiers, microphones and speakers
to bring this ideal audio environment to modern
public spaces. With these equipment so carefully
designed, it looks as good as it sounds.
This unbeatable combination of auditory and
visible quality has made P.A. systems the choice of
acoustic professionals.
