Abstract
본 발명은 다수의 디지탈 오디오 기기가 복합된 시스템에 있어서, 상기 각 디지탈 오디오 기기의 출력단에 연결된 D/A변환부를 하나의 D/A변환부로서 공통으로 사용할 수 있도록 한 복합 디지탈 오디오 시스템에 관한 것으로, 각 디지탈 오디오 기기의 출력단에 각각 별개로 D/A변환부(6)(13)를 연결 사용해야 하므로 각 디지탈 오디오 기기의 구성이 복잡하고 제품의 원가가 상승되는 문제점을 해결하기 위한 것이다.The present invention relates to a complex digital audio system in which a plurality of digital audio devices are combined, so that a D / A converter connected to an output terminal of each digital audio device can be commonly used as a single D / A converter. In order to solve the problem that the configuration of each digital audio device is complicated and the cost of the product is increased because the D / A converters 6 and 13 must be separately connected to the output terminals of the respective digital audio devices.
본 발명은 이와같은 종래 문제점을 해결하기 위하여 복합 디지탈 오디오 기기의 출력단에 공통의 D/A변환부를 연결하여 사용자가 원하는 디지탈 오디오 기기를 선택하였을 경우 마이컴은 이를 감지하여 사용자가 선택한 소오스 종류에 따라 선택스위치부를 전환하여 원하는 기기의 신호가 공통의 D/A변환부를 통해 출력될 수 있도록 한 것으로 복합 디지탈 오디오 기기에 적용한다.According to the present invention, when a user selects a desired digital audio device by connecting a common D / A converter to an output terminal of a composite digital audio device, the microcomputer detects the selection and selects the source according to the type of source selected by the user. The switch unit is switched so that a signal of a desired device can be output through a common D / A converter and applied to a composite digital audio device.
