Abstract

Nowadays, based on the advancement of IT techniques, innovative products combining IT techniques to PA system are developing. In this paper, we presented the hybrid mixer controller for digital PA system. We develop the integrated mixer controller which includes the digital mixer composing an existing digital PA system and function of digital integrated controller. Developed integrated mixer controller consists of multichannel mixer function with 16 audio input channels, 8 output channels. And, it has an equalizer for processing digital audio signal, matrix and limiter. Also, the developed controller has some features such as internet connection for controlling of overall PA system and remote monitoring of mixer process condition.

최근 IT기술의 발전을 근간으로 PA시스템에 IT기술이 접목된 혁신적인 제품들이 개발되고 있다. 본 논문에서는 디지털 전관방송을 위한 통합 믹서 컨트롤러를 제안하였다. 기존 디지털 전관방송을 구성하는 디지털믹서와 디지털 통합 컨트롤러의 기능을 포함한 통합믹서컨트롤러를 개발하였다. 개발된 통합믹서컨트롤러는 16개의 오디오입력채널과 8개의 출력채널을 가진 다채널 믹서 기능을 가진다. 그리고, 디지털오디오신호를 처리하기 위한 EQ, Matrix, Limiter을 가지고 있다. 또한, 개발된 컨트롤러는 믹서의 동작상태 모니터링과 전체 PA시스템을 제어하기 위한 인터넷 연결기능을 가진다.
