Abstract

본 발명은 다채널 오디오신호 전송시스템에 관한 것이다. 본 발명은 디지탈 오디오 소스기기와 앰프를 다채널 PCM오디오신호의 전송이 가능한 ‘MADI(Multichannel Audio Digital Interface)’로 접속하므로써 기존에 소스기기와 앰프에 중복적으로 내장되던 디코더를 소스기기에만 내장한다. 따라서, 앰프에 디지탈회로를 감소시켜 아날로그신호에 미치는 악영향을 감소시킬 수 있다. 또한, MMCD/SD등에서 지원하는 다채널의 비압축된 오디오신호나 하이샘플링의 오디오신호도 출력할 수 있는 효과를 가져온다.The present invention relates to a multichannel audio signal transmission system. According to the present invention, a digital audio source device and an amplifier are connected to a 'multi channel audio digital interface (MADI)' capable of transmitting multi-channel PCM audio signals, so that a decoder that is conventionally embedded in the source device and the amplifier is built only in the source device. . Therefore, the digital circuit in the amplifier can be reduced to reduce the adverse effect on the analog signal. In addition, multi-channel uncompressed audio signals or high-sampling audio signals supported by MMCD / SD can be output.
