Abstract
본 발명은 브이씨알의 오디오 출력 레벨 제어 장치에 관한 것으로서, 특히 아날로그 식으로 오디오 출력레벨을 제어하여 편집하는 것이 가능한 회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio output level control device of BCAL, and more particularly to a circuit capable of controlling and editing an audio output level in an analog manner.
본 발명은 브이씨알 아날로그식 오디오 출력 레벨 제어 장치에 있어서, 오디오 신호 재생계에 의해 재생된 오디오 신호가 입력되며, 외부에 놓인 오디오 신호 조절기에 의해 각 신호의 레벨을 조절하여 출력하는 레벨 합성 믹서를 포함하여 구성된 것을 특징으로 하며, 상기 레벨 합성 믹서내에는 입력되는 각 오디오 신호의 레벨 업, 다운을 위한 오디오 신호 레벨 변경 회로를 포함하며, 상기 오디오 신호 레벨 변경 회로는 레벨 합성 믹서에 입력되는 각 오디오 신호가 입력되며, 증폭기를 갖으며, 증폭기의 입력단에는 가변 저항단이 장착되며, 상기 가변 저항단을 조절하므로 입력 오디오 신호 레벨을 조절하는 것을 특징으로 한다.The present invention relates to a VAL analog audio output level control device, comprising: a level synthesizing mixer for inputting an audio signal reproduced by an audio signal reproducing system and adjusting and outputting the level of each signal by an external audio signal controller; And an audio signal level changing circuit for leveling up and down of each audio signal input in the level synthesizing mixer, wherein the audio signal level changing circuit includes each audio input to the level synthesizing mixer. The signal is input, has an amplifier, and a variable resistance stage is mounted at an input terminal of the amplifier, and the input audio signal level is adjusted by adjusting the variable resistance stage.
