Multichannel Control System of Multichannel Audio Playback System

摘要

The present invention allows the user to directly adjust each delay time and gain adjustment value for the multi-channel in the multi-channel data reproduction processing apparatus of the compact disc proposed in Patent Application No. 94-10466, and each channel in matrix form. To provide a multi-channel control device of a multi-channel audio playback system that allows for selective listening while maximizing the realism that the user feels by improving the path from the data conversion means to the amplifier so that the switch can be controlled by will be.;To this end, the present invention separates and records data obtained from a plurality of data sources into N channels, converts and compresses the music signal of each channel to digital by MPEG algorithm, and assigns a unique channel number to each channel. A key input unit 40 for selecting a channel to be listened to during playback of the compact disc having the number recorded in the channel number of the subheader, and inputting a delay time and a gain adjustment value for the selected channel; A microcomputer 42 for controlling the processing operation of the multi-channel data on the compact disc based on the gain adjustment value, and a switching for switching and outputting the data of the selected channel analog-converted by the data converting means 28 under the control of the microcomputer 42. Processing delay operation for data of the analog-converted selected channel applied through the switching means 44 and the switching switching means 44 A delay adjusting means 46 for performing the step and a gain adjusting means 48 for adjusting the gain of the data of the selected channel delayed by the delay adjusting means 46 and applying it to the amplifying means 32.;(Figure 3)
