Public address systems at meetings, shows, gathering of employees
or mass audiences of any kind make it possible mechanically to project he
human voice before a large number of people.
Mounted on a mini truck or other mobile auto, the public address
system can be transported from place to place, presenting speakers and
programmes as it goes, and reaching a widely distributed audience. Sound
tracks can also be rigged up at programmes in lieu of a permanently
installed public address system. A portable bullhorn affords great mobility
wherever amplified sound is needed.
A recording makes it possible to ‘capture’ a speech or radio
programme and replay it by radio before an audience or over a public
address system anywhere. Some recordings are made on the spot at
special events. In other instances, special programmes are deliberately
produced at are cording studio.
