MEETING FACILITIES
Audio Systems Guide for
Introduction
Introduction
Audio for meeting facilities is a topic that
encompasses a wide range of applications, from
a simple public address system in a courtroom
to a multi-channel legislative system with
recording and broadcast capabilities. Though
these systems may vary in size and complexity,
they are all governed by the same physical
principles and they share certain types of
equipment. Common components of these
systems include microphones, automatic
and non-automatic mixers, power amplifiers,
loudspeakers, and many types of electronic
signal processing devices such as equalizers,
compressors, and audio time delays. A complete
audio system may involve some or all of these
items. Proper selection and application of this
equipment requires knowledge of both the
intended purpose of the sound system and the
characteristics of individual components.
The scope of this guide is limited to the
selection and application of wired microphones,
wireless microphones, and microphone mixers
for meeting facility sound systems. Since
microphones and mixers act as the interface
between the sound source (the talker) and the
sound system, it is imperative to thoroughly
discuss these two subjects, as well as sound in
general. The objective is to provide the reader
with sufficient information to understand how
microphones and mixers are applied to
meeting facility sound situations.
