1. Brief Introduction
A IP broadcast system is composed of a microphone, broadcast software (Windows computer)
and network loudspeaker (or audio receiver). The network loudspeaker is connected through
internetwork. The broadcast can be in human voice and scheduling. The scheduling broadcast
function is to play audio (MP3/WAV) in computer at appointed time, as well as edit group function to
conduct group broadcast or multipoint broadcast. The system composition is simple. It is
unnecessary to have wiring or purchase an amplifier or player if there is a network environment.
The system’s host and loudspeaker shall be set. The audio receivers can be installed in the
broadcast system, to have network broadcast function.
