A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music.
Varizone is a fully digital public address system technology developed and produced and by Klotz Digital.. In contrast to traditional public address systems using analogue 70 or 100 volt speaker systems Varizone is a fully digital system that transmits the audio digitally to the speaker, where it is amplified by small, distributed programmable amplifier modules.
Touring systems range from mid-sized systems for bands playing nightclub and other mid-sized venues to large systems for groups playing stadiums, arenas and outdoor festivals. Tour sound systems are often designed with substantial redundancy features, so that in the event of equipment failure or amplifier overheating, the system will continue ...
1 Main Circuit (1MC) is the term for the shipboard public address circuits on United States Navy and United States Coast Guard vessels.This provides a means of transmitting general information and orders to all internal ship spaces and topside areas, and is loud enough that all embarked personnel are (normally) able to hear it.
Speech Transmission Index (STI) is a measure of speech transmission quality. The absolute measurement of speech intelligibility is a complex science. The STI measures some physical characteristics of a transmission channel (a room, electro-acoustic equipment, telephone line, etc.), and expresses the ability of the channel to carry across the characteristics of a speech signal.
For pure and new designs, the system design stage is where an Instruction set and operation is planned out, and in most chips existing instruction sets are modified for newer functionality. Design at this stage is often statements such as encodes in the MP3 format or implements IEEE floating-point arithmetic. At later stages in the design ...
A butler uses an intercom on behalf of a lady. An intercom, also called an intercommunication device, intercommunicator, or interphone, is a stand-alone voice communications system for use within a building, small collection of buildings or portably within a small coverage area, which functions independently of the public telephone network.

The basic study of system design is the understanding of component parts and their subsequent interaction with one another. [ 1 ] Systems design has appeared in a variety of fields, including sustainability, [ 2 ] computer/software architecture, [ 3 ] and sociology.
