3. PUBLIC ADDRESS SYSTEM
Public Address Systen is an sound
processor and distribution system with a
microphone,, amplifier and a
transducer(loudspeakers), used to allow
a person to address a large public.
Basically for speeches.
5. PUBLIC ADDRESS SYSTEM
Public Address Systen is an electronic
sound amplification and distribution
system with a microphone, amplifier and
a transducer(loudspeakers), used to
allow a person to address a large public.
6. SOUND REINFORCEMENT SYSTEM
This is the combination of microphones,
signal processors, amplifiers, and
loudspeakers in enclosures all controlled
by a mixing console that makes live
sound(Vocals and musical equipments)
or pre-recorded audio materials
sounds louder and may also distribute
those sounds to a larger or more distant
audience via loud speakers in the form
of sound.
7. SOUND REINFORCEMENT SYSTEM
It is a functional arrangement of electronic
components designed to amplify sound(speech,
music, from other musical equipment)
To reinforce a sound is to enhance or to give
sound more power.
The difference between PA system and Sound
reinforcement is that PA is simple and it is only
for speeeches, but Sound Reinforcement more
elaborate(i.e has more components ) used for
singing, music , speeches and reinforcement of
sound sources.

12. ROOM SIZE & ACOUSTICS
Before you set up any audio system, you need
to consider the environment it will be in. Does
the room have hard surfaces that can reflect the
sound? (i.e. sheetrock walls, glass windows,
tiled floors, wooden pews, vaulted hardwood
ceilings or a metal roof with beams and
columns) Perhaps it’s filled with stuff that
absorbs sound like heavy drapes, carpeting, and
padded chairs. It’s not that one environment is
better than another, but what type of room most
suitable.
16. NUMBER OF PEOPLE & LOCATION
For a 50-100 seats hall, the required
skill to set-up a the sound system will be
less than it would be for 2,000 seat
mega-hall. The equipment needed to
cover a small space is typically less
difficult to connect and operate. The
same applies for an enclosed space or
an open air space.
18. COMPONENTS OF PA SYSTEM
The Microphones(wired/wireless)
The Instruments/Equipment
The Audio Mixer/ Console
The Cables
The Snake
The Sound processors
The Amplifiers
The Loud Speaker
19. AUDIO MONITORING
Headphones-These are used to
monitor audio more closely.
Without it you can’t hear the
problems you need to prevent. It
can be really helpful to check
your audio on multiple sources.
A quality set of headphones will
help you hear details.
