Abstract

본 발명은 아파트, 빌딩, 공장, 공공기관의 구내 방송을 위한 디지틀사설 방송(PUBLIC ADDRESS; PA)장치에 관한 것으로, 입력된 음성신호를 디지틀화하여 다시 원래의 아날로그신호로 출력시키기 위하여 마이크 및 외부로 부터 입력되는 음성신호를 송출부(100)에 의해 증폭부 및 디지틀음성신호로 만들어 2선의 신호선을 통해 스피커수신부(300a-300n)에 출력하고 스피커의 수가 너무 많아 송출부(100)에서 보내는 출력만으로 부족할때 라인 드라이브(24)에 의해 전류 증폭하는 다수개의 중계부(200a-200n)을 설치하여 원하는 만큼의 스피커수신부(300Aa-300Nn)를 증가시켜도 깨끗한 음질을 물론이고, 설치하는데 작업의 간편성 및 비용도 절감시킬수 있는 매우 유용한 발명이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital private broadcast (PAB) device for broadcasting a premises of apartments, buildings, factories, and public institutions. The present invention relates to a microphone and an external device for digitalizing an input audio signal and outputting the original analog signal. The audio signal input from the amplification unit and the digital audio signal by the transmitter 100 is output to the speaker receivers 300a-300n through two signal lines, and the number of speakers is too high. Even if it is not enough to install a plurality of relays (200a-200n) to amplify the current by the line drive 24 to increase the number of speaker receivers (300Aa-300Nn) as desired, as well as clean sound quality, easy to install and It is a very useful invention that can reduce costs.
